Sample Question 1
What could cause coronary sinus dilation?

Atrial septal defect

Aortic valve stenosis

*Pulmonary hypertension, Tricuspid valve stenosis anything that would cause Right Atrium dilation, as coronary sinus drains deoxygenated VENOUS blood from coronary circulation into right atirum.(Check pic and visualize location)Pulmonary hypertension increases afterload for Right heart to work against it>Higher pressure in right heart)*Note that Coronary sinus is derived from Left horn of sinus venosus.(I remember this by: C LEFT=cleft :)*Now another Major HY point is that Left ventricular leads in Biventricular pacemakers course trough the coronary sinus and that coronary sinus itself resides in AtrioVentricular groove on POSTERIOR surface of the heart.*Remember Coronary sinus comes from LEFT horn of Sinus venosus.

Left atrial enlargement

Sample Question 2
Why would a person with myocardial infarction experience radiation of pain from the chest to the left shoulder and down the arm?

*Because Generel VISCERAL SENSORY pain fibers synapse in thoracic DORSAL ROOT ganglia and CNS perceives pain coming from SOMATIC regions innervated by those levels of spinal cord(Levels at which the visceral sensory fibers carrying pain synapse)*As afferent visceral cardiac fibers carrying pain enter dorsal horn at the levesl of brachial plexus pain can be perceived in region of Neck,shoulder,arm.

The pain is actually psychosomatic and not physical

Due to compression of the ulnar nerve causing referred pain

It is a result of muscle strain from overexertion in the affected areas

Sample Question 3
A female in her third trimester of pregnancy complains of light-headedness when she lies down in bed, and is noted to become hypotensive in the supine position. What is the most likely mean arterial pressure (MAP) in this situation? Why? What can she do?

*Hypotension when supine in pregnant patient should make u think of Large uterus in 3rd trimester of pregnancy compressing the IVC.*MAP(Cardiac Output xTPR) will likely be low as compression of IVC will decrease the preload(thus SV will also be decreased and subsequently CO will also be compromised-which btw equals HRxSV)*Now they love to ask management of this one:She should either start lying on the LEFT or she could place the pillow under the RIGHT hip.(To remove the weight of gravid uterus from IVC)*Also don't confuse this condition(manifest with Hypotension that gets Worse when lying down) with ORTHOSTATIC hypotension(Hypotension gets WORSE on standing and gets better when supine-here management could be rehydration if it is due to hypovolemia or salt tablets and other drugs if it is due to autonomic dysregulation), also don't confuse this condition with CHF(which would also get worse with standing-orthostatic nature, and u would also have other signs like peripheral edema)*They really want you to know that IVC is made by union of Left and Right Common iliac veins at L4 and that Renal veins join IVC at L1/2.(as we speak of IVC remember that it enter diaphragm at the level of T8)<But don't worry i'll MIND FUCK u on IVC many times lol, for now remember that pregnant lady,IVC,hypotension,pillow :)

The symptoms are indicative of congestive heart failure, and the patient should be started on diuretics.

The light-headedness is likely due to dehydration, and the patient should increase fluid intake.

The hypotension is a result of orthostatic hypotension, which can be managed by using salt tablets.
