    Low risk patients for infective endocarditis include those with:

    • Previous history of endocarditis

    • Prothetic MV

    • Intravenous drug abuse

    • CAD

    Correct Answer
    A. CAD
    Explanation
    Patients with CAD (coronary artery disease) are considered low risk for infective endocarditis. This is because infective endocarditis is typically caused by bacteria entering the bloodstream and attaching to damaged heart valves or other areas of the heart. CAD does not directly involve damage to the heart valves or increase the risk of bacterial infection. However, it is important to note that this answer assumes that the other options listed (previous history of endocarditis, prosthetic MV, intravenous drug abuse) are high risk factors for infective endocarditis.

    All of the following increase the risk for endocarditis except:

    • PDA prothetic valves

    • AS

    • CAD

    Correct Answer
    A. CAD
    Explanation
    Endocarditis is an infection of the inner lining of the heart, typically caused by bacteria entering the bloodstream. Certain conditions and factors increase the risk of developing endocarditis, such as having a prosthetic valve or a congenital heart defect like Patent Ductus Arteriosus (PDA). Aortic stenosis (AS) is also a risk factor as it causes turbulent blood flow, increasing the chance of bacteria attachment. However, CAD (Coronary Artery Disease) does not directly increase the risk of endocarditis. CAD involves the narrowing of the coronary arteries and does not affect the inner lining of the heart.

    Prosthetic cardiac valves are classified as:

    • Bioprothetic and pericardial

    • Mechanical and bioprosthetic

    • Mechanical and pericardial

    • Mechanical and bileaflet

    Correct Answer
    A. Mechanical and bioprosthetic
    Explanation
    Prosthetic cardiac valves are classified into two types: mechanical and bioprosthetic. Mechanical valves are made of synthetic materials and are designed to be durable and long-lasting. They require lifelong anticoagulant therapy to prevent blood clotting. Bioprosthetic valves, on the other hand, are made from biological tissues, such as animal or human valves, and do not require anticoagulant therapy. They are generally less durable than mechanical valves but have a lower risk of blood clotting. Therefore, the correct answer is "Mechanical and bioprosthetic."

    What is a common symptom of a patient with endocarditis?

    • Fever

    • Positional chest pain

    • Ripping chest pain

    • Aortic stenosis murmur

    Correct Answer
    A. Fever
    Explanation
    Fever is a common symptom of a patient with endocarditis. Endocarditis is an infection of the inner lining of the heart chambers and valves. It is typically caused by bacteria entering the bloodstream and attaching to damaged areas of the heart. The infection leads to inflammation, which can cause fever. Other symptoms of endocarditis may include fatigue, weight loss, night sweats, and heart murmurs. However, fever is a hallmark symptom that is commonly observed in patients with this condition.

    Rate this question:

  • 6. 

    When red blood cells become damaged as they pass through a mechanical prosthetic valve the patient is said to have:

    • Jaundice

    • Cirrhosis

    • Thrombocytopenia

    • Hemolysis

    Correct Answer
    A. Hemolysis
    Explanation
    When red blood cells become damaged as they pass through a mechanical prosthetic valve, the patient is said to have hemolysis. Hemolysis refers to the destruction or rupture of red blood cells, leading to the release of hemoglobin into the bloodstream. Mechanical prosthetic valves can cause turbulence and shear stress on the red blood cells, leading to their damage and subsequent hemolysis. This can result in symptoms such as anemia, fatigue, and jaundice.

    Which is an example of a mechanical cardiac valve?

    • St. Jude bi-leaflet

    • Hancock

    • Carpentier-Edwards

    • Lonescu-Shiley bovine pericardial

    Correct Answer
    A. St. Jude bi-leaflet
    Explanation
    The St. Jude bi-leaflet is an example of a mechanical cardiac valve. Mechanical valves are made from materials such as metal or carbon and are designed to mimic the function of a natural heart valve. The St. Jude bi-leaflet valve has two leaflets that open and close to regulate blood flow through the heart. This type of valve is commonly used in patients who require valve replacement surgery.

    All of the following are increased risk factors for valvular endocarditis except:

    • AR

    • MVP

    • Marantic

    • Carotid artery stenosis

    Correct Answer
    A. Carotid artery stenosis
    Explanation
    Carotid artery stenosis is not a risk factor for valvular endocarditis because valvular endocarditis is an infection of the heart valves, while carotid artery stenosis is a narrowing of the carotid arteries that supply blood to the brain. The other options listed, AR (aortic regurgitation), MVP (mitral valve prolapse), and marantic (nonbacterial thrombotic) endocarditis, are all known risk factors for valvular endocarditis.

    Rate this question:

  • 9. 

    All of the following are etiologies for valvular endocarditis except:

    • Pulmonary hypertension

    • Post cardiac surgery

    • Marantic

    • IV drug abuse

    Correct Answer
    A. Pulmonary hypertension
    Explanation
    Pulmonary hypertension is not an etiology for valvular endocarditis because it is a condition characterized by high blood pressure in the arteries of the lungs, whereas valvular endocarditis is an infection of the heart valves. The other options listed, such as post cardiac surgery, marantic, and IV drug abuse, are all known etiologies for valvular endocarditis.

    Rate this question:

  • 10. 

    All of the following are examples of mechanical cardiac valves except:

    • Bjork-Shiley tilting disk

    • St. Jude bi leaflet

    • Hancock

    • Starr-Edwards ball valve

    Correct Answer
    A. Hancock
    Explanation
    The correct answer is Hancock because it is not a type of mechanical cardiac valve. The other options listed are all examples of mechanical cardiac valves, such as the Bjork-Shiley tilting disk, St. Jude bi leaflet, and Starr-Edwards ball valve.

  • 11. 

    Echo finding in endocarditis often include all of the following except:

    • Shaggy appearance of valve

    • Eisenmenger syndrome

    • Pericardial effusion

    • Increased echos

    Correct Answer
    A. Eisenmenger syndrome
    Explanation
    Echo findings in endocarditis often include a shaggy appearance of the valve, pericardial effusion, and increased echos. Eisenmenger syndrome, on the other hand, is not typically associated with endocarditis. Eisenmenger syndrome is a condition where a long-standing left-to-right shunt in the heart causes pulmonary hypertension, eventually leading to a reversal of the shunt and the development of cyanosis. While endocarditis can lead to various complications, such as valve damage and heart failure, it is not directly related to the development of Eisenmenger syndrome.

    Rate this question:

  • 12. 

    Patients with Marfan syndrome often die from?

    • AR

    • MVP

    • Aortic dissection

    • Endocarditis

    Correct Answer
    A. Aortic dissection
    Explanation
    Patients with Marfan syndrome often die from aortic dissection. Marfan syndrome is a genetic disorder that affects the connective tissue, including the aorta. The aorta becomes weak and prone to tearing, leading to aortic dissection, which is a life-threatening condition. This can result in severe internal bleeding and organ damage, making aortic dissection a common cause of death in patients with Marfan syndrome.

    Rate this question:

  • 13. 

    A patient presents with a 10 year olf ball-cage prothetic valve in the mitral position with a new perivalvulat leak. What might be a cause of this leak?

    • Ring abscess

    • Cardiac tamponade

    • Pulmonary hypertension

    • Systemic hypertension

    Correct Answer
    A. Ring abscess
    Explanation
    A ring abscess can cause a perivalvular leak in a prosthetic valve. This is a complication that can occur after valve replacement surgery. A ring abscess is an infection that develops around the prosthetic valve ring, leading to tissue destruction and weakening of the valve structure. This can result in a leak around the valve, causing regurgitation of blood. It is important to diagnose and treat ring abscess promptly to prevent further complications and damage to the valve.

  • 14. 

    Patients with endocarditis may present with all of the following symptoms except:

    • Angina

    • Night sweats

    • Fever

    • New murmur

    Correct Answer
    A. Angina
    Explanation
    Patients with endocarditis may present with symptoms such as night sweats, fever, and a new murmur. Endocarditis is an infection of the inner lining of the heart chambers and valves, which can lead to inflammation and damage. This can cause symptoms like fever due to the body's immune response, night sweats due to the infection, and a new murmur due to the damaged heart valves. However, angina, which is chest pain or discomfort caused by reduced blood flow to the heart, is not typically associated with endocarditis.

    Rate this question:

  • 15. 

    In order to be seen by 2-D echo vegetations need to be how big?

    • 3mm

    • 5mm

    • 1cm

    • 0.5cm

    Correct Answer
    A. 3mm
    Explanation
    In order to be seen by 2-D echo, vegetations need to be at least 3mm in size. This means that any vegetations smaller than 3mm may not be visible on a 2-D echo.

    Rate this question:

  • 16. 

    Echo findings in endocarditis include:

    • Positive blood cultures

    • Shaggy appearance on M-mode

    • Aortic dissection

    • Pulmonary hypertension

    Correct Answer
    A. Shaggy appearance on M-mode
    Explanation
    In endocarditis, the echocardiogram findings often show a shaggy appearance on M-mode. This refers to the presence of irregular, thickened, and roughened areas on the surface of the heart valves. This finding is indicative of vegetations, which are collections of bacteria, fibrin, and inflammatory cells that adhere to the valves. The shaggy appearance on M-mode is a characteristic feature of endocarditis and helps in its diagnosis. Positive blood cultures, aortic dissection, and pulmonary hypertension are not specific findings for endocarditis.

    Rate this question:

  • 17. 

    What type of valve is a St. Jude?

    • Pericardial

    • Bi-disk

    • C) Bioprothetic

    • One leaflet

    Correct Answer
    A. Bi-disk
    Explanation
    A St. Jude valve is a type of bi-disk valve. This means that it consists of two disks that open and close to regulate the flow of blood. The bi-disk design allows for efficient blood flow and reduces the risk of blood clots. This type of valve is commonly used in heart surgeries to replace damaged or diseased heart valves.

    Rate this question:

  • 18. 

    All of the following are different types of endocarditis except:

    • Dressler’s

    • Marantic

    • Eosinophlic

    • Libman-Sachs

    Correct Answer
    A. Dressler’s
    Explanation
    Dressler's is not a type of endocarditis. It is a condition known as post-pericardiotomy syndrome, which occurs after heart surgery or a heart attack. It is characterized by inflammation of the pericardium, the sac-like covering of the heart. Endocarditis, on the other hand, is an infection of the inner lining of the heart chambers and heart valves. Marantic endocarditis is associated with nonbacterial thrombotic endocarditis, Eosinophilic endocarditis is associated with eosinophilia and Libman-Sachs endocarditis is associated with systemic lupus erythematosus.

    Rate this question:

  • 19. 

    Patients with which of the following are at increased risk for endocarditis?

    • Renal artery stenosis

    • Prothetic valves

    • Poor dental work

    • CAD

    Correct Answer
    A. Prothetic valves
    Explanation
    Patients with prosthetic valves are at an increased risk for endocarditis. Prosthetic valves can disrupt the normal flow of blood, creating areas of turbulence and promoting the formation of blood clots. These clots can serve as a nidus for bacterial colonization, leading to the development of endocarditis. Additionally, the presence of foreign material in the form of a prosthetic valve provides a surface for bacteria to adhere to and grow. Therefore, patients with prosthetic valves require prophylactic antibiotics before certain dental procedures to prevent bacterial infection and endocarditis.

    Rate this question:

  • 20. 

    All of the following statements regarding echo in patients with infective endocarditis are true except:

    • It is easy to distinguish between new and healed vegetations

    • Pre-existing valve disease may obscure the presence of a vegetation

    • Vegetations as small as 3mm can be recognized

    • Vegetations usually appear on the flow side of valve leaflets

    Correct Answer
    A. It is easy to distinguish between new and healed vegetations
    Explanation
    Echo is a commonly used imaging technique to diagnose infective endocarditis. It can help identify the presence of vegetations, which are abnormal growths on the heart valves. However, it is not always easy to distinguish between new and healed vegetations using echo alone. This is because echo cannot provide information about the age or stage of the vegetation. Other diagnostic methods, such as clinical history and blood tests, may be needed to determine the status of the vegetation.

    Rate this question:

  • 21. 

    Patients with Marfan syndrome will exhibit all of the following except:

    • AR

    • MVP

    • Aortic dilation

    • LVH

    Correct Answer
    A. LVH
    Explanation
    Marfan syndrome is a genetic disorder that affects the connective tissue in the body. It is characterized by various symptoms, including aortic dilation (enlargement of the aorta), mitral valve prolapse (MVP), and aortic regurgitation (AR). However, left ventricular hypertrophy (LVH), which refers to the thickening of the walls of the left ventricle of the heart, is not typically associated with Marfan syndrome. Therefore, patients with Marfan syndrome will exhibit all of the given symptoms except for LVH.

    Rate this question:

  • 22. 

    If a patient has a porcine MV, all of the following should be ruled out during an echo except:

    • Thrombus formation

    • Ring abscess

    • Valve dehiscence

    • Carcinoid heart disease

    Correct Answer
    A. Carcinoid heart disease
    Explanation
    The correct answer is carcinoid heart disease. Carcinoid heart disease is a rare condition caused by the release of certain chemicals by tumors called carcinoids. It affects the tricuspid and pulmonary valves, not the mitral valve. Thrombus formation, ring abscess, and valve dehiscence are all potential complications that should be ruled out during an echo for a patient with a porcine mitral valve.

  • 23. 

    Coarctation of the aorta is associated with:

    • Bicuspid AV

    • MVP

    • Pulmonary stenosis

    • Endocarditis

    Correct Answer
    A. Bicuspid AV
    Explanation
    Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, the main artery that carries oxygenated blood from the heart to the rest of the body. Bicuspid AV refers to a condition where the aortic valve, which controls blood flow from the heart into the aorta, has only two cusps instead of the normal three. This condition is commonly associated with coarctation of the aorta, as the abnormal valve can contribute to the development of the narrowing in the aorta.

    Rate this question:

  • 24. 

    Which is an example of a bioprothetic cardiac valve?

    • St. Jude bi-leaflet

    • Starr-Edwards ball valve

    • Bjork-Shirley tilting disk

    • Lonescu-Shiley bovine pericardial

    Correct Answer
    A. Lonescu-Shiley bovine pericardial
    Explanation
    The Lonescu-Shiley bovine pericardial valve is an example of a bioprothetic cardiac valve. It is made from the pericardial tissue of a bovine (cow) and is used to replace a damaged or diseased heart valve. Bioprothetic valves are often preferred over mechanical valves because they do not require long-term use of blood thinners and have a lower risk of blood clots.

    Rate this question:

  • 25. 

    In endocarditis the vegetations usually attach on:

    • The flow side of the valve

    • Abnormal leaflets only

    • Only one leaflet

    • The down-stream side of a valve

    Correct Answer
    A. The flow side of the valve
    Explanation
    In endocarditis, the vegetations usually attach on the flow side of the valve. This is because the flow side of the valve is constantly exposed to the high-pressure blood flow, making it more susceptible to damage and the formation of vegetations. These vegetations are made up of platelets, fibrin, and bacteria, and can lead to complications such as valve dysfunction and embolization. Attaching on the flow side allows the vegetations to interfere with the normal flow of blood through the valve, causing further damage and increasing the risk of complications.

    Rate this question:

  • 26. 

    Patients with lupus will sometimes get what type of endocarditis?

    • Eosinophilic

    • Marantic

    • Libman-Sachs

    • Staph aureus

    Correct Answer
    A. Libman-Sachs
    Explanation
    Libman-Sachs endocarditis is a type of non-infectious endocarditis commonly seen in patients with systemic lupus erythematosus (lupus). It is characterized by the formation of sterile vegetations on the heart valves due to immune complex deposition. This condition can lead to valvular dysfunction and complications such as heart failure or embolization. Therefore, the correct answer is Libman-Sachs.

    Rate this question:

  • 27. 

    Patients with an aortic coarctation commonly have blood pressure in the legs?

    • Lower than the right arm

    • Higher than the right arm

    • Unable to record

    • Equal to the right arm

    Correct Answer
    A. Lower than the right arm
    Explanation
    Patients with an aortic coarctation commonly have lower blood pressure in the legs compared to the right arm. This is because aortic coarctation is a narrowing of the aorta, which reduces blood flow to the lower body. As a result, the blood pressure in the legs is lower than in the arm.

    The normal pHT for a mitral prothetic valve is:

    • 8 mmHg

    • 1-3 m/sec

    • >280 msec

    Correct Answer
    A.
  • 29. 

    Coarctation of the aorta most often occurs at the?

    • Aortic isthmus

    • Thoracic aorta

    • Ascending aorta

    • Aortic sinuses

    Correct Answer
    A. Aortic isthmus
    Explanation
    Coarctation of the aorta is a narrowing of the aorta, the main artery that carries oxygenated blood from the heart to the rest of the body. It most commonly occurs at the aortic isthmus, which is the narrowest part of the aorta just distal to the origin of the left subclavian artery. This narrowing can lead to increased pressure in the upper body and decreased blood flow to the lower body. Treatment usually involves surgical repair or balloon angioplasty to widen the narrowed area.

    If the patients pulmonic valve, annulus and trunk are excised and relocated to the aortic position, what type of valve do they have?

    • Autograft

    • Heterograft

    • Mechanical

    • Homograft

    Correct Answer
    A. Autograft
    Explanation
    If the patient's pulmonic valve, annulus, and trunk are excised and relocated to the aortic position, they would have an autograft. An autograft refers to a surgical procedure where tissue is taken from one part of the patient's body and transplanted to another location within the same individual. In this case, the patient's own pulmonic valve, annulus, and trunk are being used to replace the aortic valve, making it an autograft.

  • 31. 

    All of the following will cause aortic dilatation except:

    • Pulmonary hypertension

    • Systemic hypertension

    • Type I dissection

    • Marfan syndrome

    Correct Answer
    A. Pulmonary hypertension
    Explanation
    Pulmonary hypertension is not typically associated with aortic dilatation. Aortic dilatation refers to the enlargement or widening of the aorta, the main artery that carries oxygenated blood from the heart to the rest of the body. While systemic hypertension (high blood pressure), Type I dissection (a tear in the inner layer of the aorta), and Marfan syndrome (a genetic connective tissue disorder) can all contribute to aortic dilatation, pulmonary hypertension primarily affects the blood vessels in the lungs, not the aorta. Therefore, pulmonary hypertension is the exception in this list of potential causes of aortic dilatation.

  • 32. 

    You are in the emergency department and a patient presents with the signs and symtoms of aortic dissection. Which modality would give you the most rapid diagnosis?

    • Chest CT

    • X-ray

    • TEE

    • MRI

    Correct Answer
    A. TEE
    Explanation
    Transesophageal echocardiography (TEE) would provide the most rapid diagnosis for a patient presenting with signs and symptoms of aortic dissection in the emergency department. TEE is a minimally invasive imaging technique that uses an ultrasound probe inserted into the esophagus to obtain detailed images of the heart and aorta. It allows for real-time visualization of the aorta and can quickly identify the presence of a dissection. Chest CT and MRI are also imaging modalities that can diagnose aortic dissection, but they may take longer to perform and interpret compared to TEE. X-ray is not as sensitive or specific for diagnosing aortic dissection compared to the other modalities mentioned.

    The majority of organisms attach to the ____ side of the atrioventricular valves:

    • Downstream

    • Ventricular

    • Atrial

    • Epicardial

    Correct Answer
    A. Atrial
    Explanation
    The correct answer is "Atrial." This is because the atrioventricular valves are located between the atria and ventricles of the heart. When the heart contracts, blood flows from the atria to the ventricles, and the atrioventricular valves prevent backflow of blood. Therefore, it is logical for organisms to attach to the atrial side of these valves, as this is the side where blood is coming from.

    When using Doppler to interrogate a Starr-Edwards mitral valve which window would you use?

    • Parasteral

    • Suprasternal

    • Subcostal

    • Apical

    Correct Answer
    A. Apical
    Explanation
    The apical window would be used when using Doppler to interrogate a Starr-Edwards mitral valve. The apical window provides a view of the heart from the apex, allowing for visualization and assessment of the mitral valve. This window is commonly used to obtain Doppler measurements and evaluate the function of the mitral valve.

    The degree of prothetic valce stenosis depends on all of the following except:

    • Presence of regurg

    • Valve type

    • Valve size

    • Degree of pannus growth

    Correct Answer
    A. Presence of regurg
    Explanation
    The degree of prothetic valve stenosis depends on valve type, valve size, and degree of pannus growth. The presence of regurgitation, however, does not directly affect the degree of stenosis. Regurgitation refers to the backward flow of blood through the valve, while stenosis refers to the narrowing of the valve opening. These are two separate conditions that can occur simultaneously but do not directly impact each other in terms of determining the degree of stenosis.

    All of the following are examples of bioprosthetic cardiac valves except:

    • Starr-edwards ball valve

    • Lonescu-Shiley bovine pericardial

    • Hancock

    • Carpentier-Edwards

    Correct Answer
    A. Starr-edwards ball valve
    Explanation
    The Starr-edwards ball valve is not an example of a bioprosthetic cardiac valve. Bioprosthetic valves are made from animal tissue, such as bovine pericardial tissue or porcine valves, and are used to replace damaged or diseased heart valves. The Starr-edwards valve, on the other hand, is a mechanical valve that consists of a metal ball and cage. It is not made from animal tissue and does not fall under the category of bioprosthetic valves.

    High frequency systolic vibrations on the aortic valve M-mode is consistent with:

    • Normal findings

    • Aortic stenosis

    • Low cardiac output

    • Aortic regurgitation

    Correct Answer
    A. Normal findings
    Explanation
    High frequency systolic vibrations on the aortic valve M-mode are consistent with normal findings. This indicates that the aortic valve is functioning properly and there are no abnormalities such as aortic stenosis (narrowing of the valve), low cardiac output (reduced blood flow from the heart), or aortic regurgitation (leaking of blood back into the heart). The presence of high frequency systolic vibrations suggests that the valve is opening and closing efficiently, allowing blood to flow smoothly through the aorta.

    Rate this question:

  • 39. 

    An M-mode of a mitral heterograft valve resembles an M-mode of which valve?

    • Pulmonic

    • Aortic

    • Mitral

    • Tricuspid

    Correct Answer
    A. Aortic
    Explanation
    The correct answer is Aortic. An M-mode of a mitral heterograft valve resembles an M-mode of the aortic valve. M-mode is a type of echocardiographic imaging that allows for the visualization of the movement of heart structures over time. In this case, the mitral heterograft valve, which is a prosthetic valve used to replace the mitral valve, would have a similar appearance and movement pattern to the aortic valve when viewed using M-mode imaging.

    Rate this question:

  • 40. 

    If a patient has Starr-Edwards valve in both the mitral and aortic positions mitral regurg might be best detected from which window?

    • Left parasternal

    • Suprasternal

    • Apical

    • Subcostal

    Correct Answer
    A. Subcostal
    Explanation
    The subcostal window is the best position to detect mitral regurgitation in a patient with Starr-Edwards valves in both the mitral and aortic positions. This is because the subcostal window provides a clear view of the mitral valve and allows for accurate assessment of regurgitation. The other windows mentioned, such as left parasternal, suprasternal, and apical, may not provide as clear or direct a view of the mitral valve, making it more difficult to detect regurgitation.
