    An extra electrical pathway that connects the atria and ventricles and causes rapid heartbeat.

    • Tetralogy of Fallot 

    • Ebstein's anomaly  

    • Wolff-Parkinson-White syndrome  

    • Dextrocardia

    Correct Answer
    A. Wolff-Parkinson-White syndrome  
    Explanation
    Wolff-Parkinson-White syndrome is the correct answer because it is a condition characterized by the presence of an extra electrical pathway between the atria and ventricles. This pathway, called the Bundle of Kent, bypasses the normal electrical conduction system of the heart and causes rapid heartbeat or tachycardia. This can lead to symptoms such as palpitations, dizziness, and shortness of breath. Treatment options for Wolff-Parkinson-White syndrome may include medications, catheter ablation, or surgery to remove the abnormal pathway.

    Small muscular defects often close spontaneously

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Small muscular defects often close spontaneously, meaning that they can heal on their own without any intervention or treatment. This is true because the body has the ability to repair small defects in muscles through natural healing processes. These defects may be caused by various factors such as injury or strain, and the body's natural healing mechanisms can effectively close them over time. However, it is important to note that larger or more severe muscular defects may require medical intervention or surgical procedures to facilitate proper healing.

    Refers to a group of congenital heart defects in which there is a normal amount of oxygen in the bloodstream, giving a pink color to the lips and nail beds.

    • Acyanotic

    • Atresia

    • Ectopia cordis

    • Pericardiocentesis

    Correct Answer
    A. Acyanotic
    Explanation
    Acyanotic refers to a group of congenital heart defects where there is a normal amount of oxygen in the bloodstream, resulting in a pink coloration of the lips and nail beds. This means that the blood is adequately oxygenated and there is no cyanosis, which is the bluish discoloration of the skin due to low oxygen levels. Therefore, acyanotic is the correct answer as it accurately describes the condition mentioned in the question.

    Least common ASD seen near entrance of SVC into the right atrium

    • Ostium primum

    • Ostium secundum

    • Sinus venosus

    • Muscular VSD

    Correct Answer
    A. Sinus venosus
    Explanation
    The correct answer is Sinus venosus. Sinus venosus is the least common atrial septal defect (ASD) and is typically located near the entrance of the superior vena cava (SVC) into the right atrium. This type of defect occurs when there is an abnormal connection between the SVC and the right atrium, allowing oxygenated blood from the left atrium to mix with deoxygenated blood from the right atrium. The other options, Ostium primum, Ostium secundum, and Muscular VSD, are different types of ASDs but are not specifically associated with the entrance of the SVC into the right atrium.

    Rate this question:

  • 6. 

    Complete atrioventricular septal defects are more complex to repair because defect is larger and a single atrioventricular valve more difficult to manage clinically, depending on amount of regurgitation present.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Complete atrioventricular septal defects are indeed more complex to repair. This is because the defect is larger, making it more challenging to close surgically. Additionally, these defects involve a single atrioventricular valve, which can be more difficult to manage clinically, especially if there is regurgitation present. Therefore, the statement is true.

  • 7. 

    Sinus venosus defect is associated with 

    • Cleft mitral valve

    • MVP

    • Anomalous pulmonary venous return

    • VSD

    Correct Answer
    A. Anomalous pulmonary venous return
    Explanation
    Sinus venosus defect is a congenital heart defect where there is an abnormal connection between the right atrium and the pulmonary veins. This results in the mixing of oxygenated and deoxygenated blood, leading to a decrease in oxygen levels in the body. Anomalous pulmonary venous return is another congenital heart defect where the pulmonary veins do not connect to the left atrium properly. Since both conditions involve abnormalities in the pulmonary veins, it is reasonable to associate sinus venosus defect with anomalous pulmonary venous return.

    Refers to the condition in which the heart is displaced further towards the left chest, usually in association with a space-occupying lesion

    • Dextrocardia

    • Levocardia

    • Normal situs

    • Sinus inversus 

    Correct Answer
    A. Levocardia
    Explanation
    Levocardia refers to the condition in which the heart is displaced further towards the left chest, usually in association with a space-occupying lesion. This means that the heart is positioned normally, with the apex pointing towards the left side of the chest. Dextrocardia, on the other hand, refers to the condition in which the heart is displaced towards the right side of the chest. Normal situs refers to the normal positioning of the internal organs, while sinus inversus refers to the mirror image reversal of the internal organs.

    • Ostium primum

    • Ostium secundum

    • Sinus venosus

    • Coronay sinus

    Correct Answer
    A. Sinus venosus
    Explanation
    The correct answer is sinus venosus. Sinus venosus is a small area located in the superior portion of the atrial septum, close to the inflow pattern of the superior vena cava (SVC). It is one of the four main types of atrial septal defects (ASDs), along with ostium primum, ostium secundum, and coronary sinus defects.

    ASD that is in central atrial septum near foramen ovale

    • Ostium primum

    • Ostium secundum

    • Sinus venosus 

    • Coronary sinus

    Correct Answer
    A. Ostium secundum
    Explanation
    The correct answer is "ostium secundum". The explanation for this is that the ASD (atrial septal defect) is located in the central atrial septum near the foramen ovale. The foramen ovale is a natural opening between the two atria of the heart during fetal development, and it usually closes shortly after birth. However, in some cases, it may not close completely, resulting in an ASD. The ostium secundum is the most common type of ASD, accounting for about 70-80% of cases. It is located in the central part of the atrial septum, making it the most likely location for the ASD described in the question.

    Which ASD is this?

    • Ostium primium

    • Ostium secundum

    • Sinus venosus

    • Not and ASD

    Correct Answer
    A. Ostium secundum
    Explanation
    The given answer "ostium secundum" refers to a specific type of atrial septal defect (ASD). ASDs are abnormal openings in the wall separating the two upper chambers of the heart. In the case of an ostium secundum ASD, the defect is located in the middle of the atrial septum, allowing blood to flow between the atria. This type of ASD is one of the most common and typically requires medical intervention to prevent complications.

    May be seen in ASD malformation in which there is malalignment of atrioventricular valves secondary to defect

    • Ostium primum

    • Ostium secundum

    • Sinus venosus

    • Coronary sinus

    Correct Answer
    A. Ostium primum
    Explanation
    The correct answer is Ostium primum. In ASD (Atrial Septal Defect) malformation, there is malalignment of the atrioventricular valves due to a defect. The ostium primum is a type of ASD where there is an abnormal opening in the lower part of the atrial septum. This opening allows blood to flow between the left and right atria, causing a shunt. The malalignment of the atrioventricular valves can lead to regurgitation and further complications.

    Indirect findings from ASD

    • Volume overload of right heart, volume overload of left heart

    • Volume overload of right heart, PHT

    • Volume overload of left heart, PHT

    • Volume overload of left heart, hypertension

    Correct Answer
    A. Volume overload of right heart, PHT
    Explanation
    The correct answer is volume overload of right heart, PHT. This is because the question is asking for the indirect findings from ASD (atrial septal defect). ASD is a congenital heart defect where there is a hole in the wall separating the two upper chambers of the heart. This can lead to increased blood flow and volume overload in the right side of the heart. Over time, this can cause pulmonary hypertension (PHT), which is an increase in blood pressure in the arteries of the lungs. Therefore, the correct answer is volume overload of right heart, PHT.

    Primum ASD is associated with:

    • Cleft mitral valve

    • MVP

    • Anomalous pulmonary venous return

    • VSD

    Correct Answer
    A. Cleft mitral valve
    Explanation
    Primum ASD, also known as atrial septal defect, is a congenital heart defect characterized by an abnormal opening in the septum between the atria. This condition is commonly associated with other cardiac abnormalities, such as cleft mitral valve. A cleft mitral valve is a malformation of the mitral valve, which separates the left atrium from the left ventricle. This abnormality can cause blood to flow back into the atrium, leading to symptoms like heart murmurs and heart failure. Therefore, it is associated with primum ASD.

    How much pericardial effusion is too much?

    • 2.0mm

    • >2.0mm

    • >1.0mm

    • 1.0 mm

    Correct Answer
    A. >2.0mm
    Explanation
    A pericardial effusion greater than 2.0 mm in thickness is generally considered significant and may indicate an abnormal accumulation of fluid around the heart. This can lead to complications such as cardiac tamponade, which requires prompt medical attention. Effusions smaller than 2.0 mm are typically not as concerning, though clinical context is important for proper evaluation.

    Rate this question:

  • 17. 

    How much pericardial effusion should there be?

    • < 2.0 mm

    • > 2.0

    • 5.0 mm

    • >3.0 mm

    Correct Answer
    A. < 2.0 mm
    Explanation
    Pericardial effusion is the accumulation of fluid in the pericardial sac surrounding the heart. The given correct answer suggests that the amount of pericardial effusion should be less than 2.0 mm. This indicates that a small amount of fluid is considered normal, but if it exceeds this measurement, it may indicate a pathological condition. Therefore, the answer implies that a pericardial effusion greater than 2.0 mm is abnormal and requires further evaluation.

    Atypical location of the heart, with cardiac apex pointing towards the midline of the chest

    • Dextrocardia

    • Levocardia

    • Mesocardia

    • Sinus inversus 

    Correct Answer
    A. Mesocardia
    Explanation
    Mesocardia refers to the atypical location of the heart where the cardiac apex points towards the midline of the chest. In this condition, the heart is not located in its usual position. Dextrocardia refers to the heart being located on the right side of the chest, while levocardia refers to the heart being located on the left side of the chest. Sinus inversus refers to the reversal of the normal positions of organs in the chest and abdomen. Therefore, mesocardia is the correct answer as it specifically describes the heart's atypical location with the apex pointing towards the midline of the chest.

    Most difficult to see in urtero because flap of foramen ovale mobile at this point of development

    • Sinus venosus

    • Ostium primum

    • Ostium secundum

    • Muscular VSD 

    Correct Answer
    A. Ostium secundum
    Explanation
    The correct answer is Ostium secundum. The reason why it is the most difficult to see in utero is because the flap of the foramen ovale is mobile at this point of development. The foramen ovale is a hole in the heart that allows blood to bypass the lungs in the fetal stage. The ostium secundum is the second opening of the foramen ovale, and it is located in the septum between the atria. The mobility of the flap in the ostium secundum makes it harder to visualize during prenatal ultrasounds.

    Incomplete ASD is a failure of:

    • Blood moving from right to left

    • To be seen on echo

    • Endocardial cushion to fuse

    • Valve formation 

    Correct Answer
    A. Endocardial cushion to fuse
    Explanation
    Incomplete ASD refers to a condition where the endocardial cushion, which is responsible for the fusion of the heart valves, fails to fully close. This can result in a communication between the right and left atria of the heart, allowing blood to flow from the right side to the left side. This defect can be detected through an echocardiogram, a non-invasive imaging technique used to visualize the heart's structures and blood flow.

    Correct Answer
    A. Four-chamber view
    Explanation
    The correct answer is four-chamber view. In this view, the complete absence of the interatrial septum can be occasionally observed in fetuses. This refers to a condition known as atrial septal defect (ASD), where there is a hole in the wall that separates the two upper chambers of the heart. This defect can be detected during prenatal ultrasound examinations, specifically in the four-chamber view, which allows visualization of the entire heart and its chambers.

  • 22. 

    If myocardium is thick due to something being inside the myocardium such as sarcodosis, the type of cariomyopathy is:

    • Dilated

    • Infiltrative

    • Hypertrophic 

    • None of the above

    Correct Answer
    A. Infiltrative
    Explanation
    If the myocardium is thick due to something being inside it, such as sarcoidosis, the type of cardiomyopathy is infiltrative. Infiltrative cardiomyopathy refers to a condition where abnormal substances, such as sarcoidosis granulomas, infiltrate the myocardium and cause thickening. This can lead to impaired heart function and other symptoms. Dilated cardiomyopathy is characterized by the enlargement of the heart chambers, while hypertrophic cardiomyopathy involves the thickening of the heart muscle itself. None of these conditions specifically address the presence of something inside the myocardium, making infiltrative the correct answer.

    Rate this question:

  • 23. 

    How would you describe a condition where the left ventricle (LV) is enlarged, but the myocardium (muscle of the heart wall) becomes smaller in size?

    • Hypertrophic

    • Infiltrative 

    • Dilated

    • None of the above 

    Correct Answer
    A. Dilated
    Explanation
    The given statement suggests that LV (left ventricle) is bigger, but the myocardium (heart muscle) gets smaller in size. This indicates that there is dilation of the left ventricle. In dilated cardiomyopathy, the left ventricle becomes enlarged and weakened, causing it to pump blood less effectively. This condition can lead to symptoms such as fatigue, shortness of breath, and fluid retention. Therefore, the correct answer is "Dilated."

    • Herediatary factors, chromosomal factors, underlying issues 

    Correct Answer
    A. Environmental factors, chromosomal factors, hereditary factors
    Explanation
    The development of congenital heart disease in the fetus can be influenced by a combination of environmental factors, chromosomal factors, and hereditary factors. Environmental factors refer to external factors such as exposure to toxins or infections during pregnancy. Chromosomal factors involve abnormalities or mutations in the baby's chromosomes. Hereditary factors indicate a genetic predisposition to heart disease passed down from parents. These three factors together contribute to the risk and development of congenital heart disease in the fetus.

    When the heart is in the right chest with apex pointed to the right of thorax

    • Dextrocardia

    • Levocardia

    • Mesocardia

    • SInus invertus

    Correct Answer
    A. Dextrocardia
    Explanation
    Dextrocardia refers to a condition where the heart is located in the right chest rather than the left, with the apex pointing towards the right side of the thorax. This is a rare congenital condition that occurs during fetal development. In dextrocardia, the heart's position is reversed, but its internal structures and connections remain normal. It can be associated with other abnormalities, such as situs inversus, where the internal organs are mirrored from their normal positions. Dextrocardia can sometimes lead to complications in diagnosis and treatment, as medical professionals may mistakenly expect to find the heart on the left side.

    Frequency for pediatric probes

    • 1.5 HHz 

    • 12 MHz

    • 20 MHz

    • 17 MHz

    Correct Answer
    A. 12 MHz
    Explanation
    The frequency of 12 MHz is the correct answer for pediatric probes because it falls within the range commonly used for imaging in pediatric patients. Pediatric probes are designed to be used on infants and young children, and they typically have higher frequencies compared to probes used on adult patients. Higher frequency probes provide better resolution and are better suited for imaging smaller structures, such as those found in pediatric patients. Therefore, a frequency of 12 MHz is appropriate for pediatric imaging.

    What 2D image would you see your pericardial effusion which is anterior to your RV

    • Apical 4

    • Subcostal

    • PSLA

    • Apical 2

    Correct Answer
    A. Subcostal
    Explanation
    The subcostal view is the most appropriate 2D image to visualize a pericardial effusion that is anterior to the right ventricle (RV). This view is obtained by placing the ultrasound probe just below the costal margin, allowing for visualization of the heart from a lower angle. This angle provides a clear view of the anterior structures of the heart, including the RV, making it ideal for detecting and evaluating pericardial effusions in this location. The other options, such as the apical 4, apical 2, and PSLA views, may not provide the same level of visibility for anterior pericardial effusions.

    Explanation
    The correct answer is crista supraventricularis ridge. This is a significant anatomical landmark in ventricular septal defects (VSDs). The crista supraventricularis is a muscular ridge that separates the right and left ventricles in the heart. In VSDs, there is an abnormal opening in the septum between the ventricles, and the crista supraventricularis ridge can help identify the location and extent of the defect. It serves as a reference point for surgeons during repair procedures. The other options listed, such as the foramen ovale, coumadin ridge, and anterior mitral leaflet, are not specific landmarks associated with VSDs.

    16 year old patient comes in for an echo, which probe would you use?

    • 3.5 MHz

    • 12 MHz

    • 2.5MHz

    • 50 MHz

    Correct Answer
    A. 3.5 MHz
    Explanation
    The correct answer is 3.5 MHz. This is because the frequency of the probe should be chosen based on the depth of the structures being imaged. In this case, since the patient is 16 years old, a lower frequency probe like 3.5 MHz would be appropriate as it can penetrate deeper into the body and provide better visualization of the heart structures. Higher frequency probes like 12 MHz or 50 MHz are typically used for superficial imaging.

    What is this?

    • Normal

    • Dextrocardia

    • Sinus invertus

    • Levocardia

    Correct Answer
    A. Normal
    Explanation
    The given options are all related to cardiac conditions. Normal refers to a typical or healthy condition, where the heart is positioned in the left side of the chest. Dextrocardia refers to a condition where the heart is positioned on the right side of the chest. Sinus invertus is a condition where the internal organs are mirrored or reversed in position. Levocardia refers to a normal position of the heart on the left side of the chest. Since the question is asking for what "this" is, and the options are all cardiac conditions, the correct answer would be Normal.

    Usually associated with chromosomal abnormality of trisomy 21

    •  Ostium primum ASD

    • Ostium secundum ASD

    • Sinus venosus ASD

    • Dextrocardia 

    Correct Answer
    A.  Ostium primum ASD
    Explanation
    Ostium primum ASD is usually associated with chromosomal abnormality of trisomy 21, also known as Down syndrome. Trisomy 21 is characterized by the presence of an extra copy of chromosome 21, which can lead to various developmental abnormalities, including heart defects. Ostium primum ASD refers to a specific type of atrial septal defect, where there is an abnormal opening in the lower part of the atrial septum. This defect is commonly seen in individuals with Down syndrome.

    May be seen in ASD malformation in which there is malalignment of atrioventricular valves secondary to defect

    • Ostium primum

    • Ostium secundum

    • Sinus venosus

    • Perimembranous inlet 

    Correct Answer
    A. Ostium primum
    Explanation
    The correct answer is "Ostium primum." In ASD (atrial septal defect) malformation, there is a malalignment of the atrioventricular valves due to a defect. The ostium primum is a type of ASD where there is a defect in the lower part of the atrial septum, near the atrioventricular valves. This defect allows blood to flow between the left and right atria, leading to a shunting of blood and potentially causing symptoms such as shortness of breath and fatigue.

    Most common single cardiac abnormality is

    • VSD

    • ASD

    • PDA

    • Dextrocardia 

    Correct Answer
    A. VSD
    Explanation
    VSD stands for Ventricular Septal Defect, which is the most common single cardiac abnormality. It is a congenital heart defect where there is a hole in the wall (septum) that separates the two lower chambers of the heart (ventricles). This hole allows oxygen-rich and oxygen-poor blood to mix, leading to inefficient circulation and potentially causing symptoms such as shortness of breath, poor growth, and fatigue. VSD can vary in size and severity, and treatment options include medication, catheter-based procedures, and surgery.

    VSD accounts for ____% of all structural heart defects

    • 10%

    • 15%

    • 20%

    • 30%

    Correct Answer
    A. 30%
    Explanation
    Ventricular septal defect (VSD) is a common type of structural heart defect where there is a hole in the wall separating the two lower chambers of the heart. The given answer, 30%, suggests that VSD accounts for 30% of all structural heart defects. This means that out of all the different types of heart defects, VSD is responsible for approximately one-third of them.

    Correct Answer
    A. Perimembranous
    Explanation
    This question is asking about the type of VSD (ventricular septal defect). The correct answer is "perimembranous." This type of VSD is located near the membrane that separates the ventricles of the heart. It is the most common type of VSD and is often associated with other heart abnormalities.

    • None of the above

    Correct Answer
    A. Trisomy 21, trisomy, 13, trisomy 18 and Turner's syndrome
    Explanation
    The correct answer is "Trisomy 21, trisomy, 13, trisomy 18 and Turner's syndrome." This is because the question is asking for the chromosomal abnormalities that are commonly associated with congenital heart disease. Trisomy 21 (Down syndrome), trisomy 13 (Patau syndrome), trisomy 18 (Edwards syndrome), and Turner's syndrome are all known to be linked to congenital heart disease.

    In _____ cardiomyopathy, all four chambers dilated, with thinning of myocardial walls

    • Restrictive 

    • Hypertrophic 

    • Constrictive 

    • Viral

    Correct Answer
    A. Viral
    Explanation
    In viral cardiomyopathy, all four chambers of the heart dilate and the myocardial walls become thinner. This condition is caused by a viral infection that affects the heart muscle, leading to inflammation and damage. As a result, the heart becomes weakened and enlarged, leading to symptoms such as fatigue, shortness of breath, and fluid retention. Treatment for viral cardiomyopathy typically involves managing symptoms and addressing the underlying viral infection.
