A 32-year-old male who has been diagnosed as having aortic stenosis secondary to a bicuspid aortic valve develops classical angina pectoris after running 1.5 miles on uphill terrain. He consults a physician who confirms the diagnosis and determines that on examination his BP is 140/60 mmHg, and the patient has a harsh systolic ejection murmur radiating to the neck accompanied by a diastolic murmur compatible with associated aortic regurgitation. What is the mechanism for his chest pain most likely to be?
- A.
Supply/demand imbalance
- B.
Undiagnosed coronary artery disease
- C.
Abnormal diastolic blood pressure
- D.
Increased ventricular compliance
- E.
Low O2 saturation
Correct Answer
A. Supply/demand imbalanceExplanation
The mechanism for his chest pain is most likely to be a supply/demand imbalance. This is because aortic stenosis, which the patient has, restricts blood flow from the heart to the rest of the body, leading to inadequate oxygen supply to the myocardium. During exercise, the demand for oxygen by the heart increases, but the stenotic aortic valve cannot deliver enough oxygenated blood to meet this demand. This results in chest pain, known as angina pectoris. The symptoms are aggravated during exercise due to the increased demand for oxygen.Rate this question:

A 30 year old woman presents for a routine checkup. She has no complaints and denies previous medical problems. On heart examination, the patient has a loud S1. She has a low-pitched mid-to-late diastolic murmur that is heard best at the apex. Immediately preceding the murmur is a loud extra sound. Which of the following is the most likely diagnosis?
- A.
Aortic stenosis
- B.
Mitral valve prolapsed
- C.
Ventricular septal defect
- D.
Aortic insufficiency
- E.
Mitral stenosis
Correct Answer
E. Mitral stenosisExplanation
Upon auscultation of an individual with mitral stenosis, the first heart sound is unusually loud and may be palpable (tapping apex beat) because of increased force in closing the mitral valve.
An opening snap which is a high pitched additional sound may be heard after the A2 (aortic) component of the second heart sound (S2), which correlates to the forceful opening of the mitral valve.
A mid-diastolic rumbling murmur with presystolic accentuation will be heard after the opening snap. The murmur is best heard at the apical region and is not radiated. Since it is low-pitched it is heard best with the bell of the stethoscope.Rate this question:

You have been seeing a 2-year-old female child at your clinic who has Tetralogy of Fallot. The parents are concerned because she has often been seen taking a "squatting" position on the floor multiple times per day. Since you know this is normal behavior, how do you explain it to the parents?
- A.
It prevents blood from flowing out of the heart causing it to go into the lungs
- B.
It changes the flow of electrical current in the heart
- C.
It prevents blood from flowing into the liver where it may pool
- D.
It decreases the flow of blood returning to the heart
- E.
It causes more blood to be shunted to the brain
Correct Answer
A. It prevents blood from flowing out of the heart causing it to go into the lungsExplanation
The squatting position that the child takes helps to relieve the symptoms of Tetralogy of Fallot. This condition involves a combination of heart defects that result in decreased blood flow to the lungs. By squatting, the child increases the resistance in the blood vessels in the legs, which helps to prevent blood from flowing out of the heart too quickly. This allows more blood to flow into the lungs, improving oxygenation and relieving symptoms.Rate this question:

Which of the following are the mechanisms of left atrial failure in a patient with a mitral stenosis?
- A.
Reduced preload, volume overload, and pressure overload
- B.
Volume overload, pressure overload, and impaired contractility
- C.
Increased preload, increased afterload, and impaired contractility
- D.
Increased preload, reduced afterload, and impaired contractility
Correct Answer
B. Volume overload, pressure overload, and impaired contractilityExplanation
Left atrial failure in a patient with mitral stenosis can be explained by volume overload, pressure overload, and impaired contractility. Mitral stenosis leads to a narrowing of the mitral valve, which obstructs blood flow from the left atrium to the left ventricle. This obstruction causes an increase in pressure within the left atrium, leading to pressure overload. Additionally, the narrowed valve prevents proper emptying of the left atrium, causing blood to accumulate and leading to volume overload. Finally, the continuous strain on the left atrium can result in impaired contractility, further contributing to left atrial failure.Rate this question:

WHY are his briefs on backwards??????
About half of the cases of aortic insufficiency are due to the aortic root dilatation (annuloaortic ectasia), which is idiopathic in over 80% of cases, but otherwise may result from aging, syphilitic aortitis, osteogenesis imperfecta, aortic dissection, Behçet's disease, reactive arthritis and systemic hypertension.[2] In about 15% the cause is innate bicuspidal aortic valve, while another 15% cases are due to retraction of the cusps as part of postinflammatory processes of endocarditis in rheumatic fever and various collagen vascular diseases. Additionally, aortic insufficiency has been linked to the use of some medications, specifically medications containing fenfluramine or dexfenfluramine isomers and dopamine agonists.
Other potential causes that affects the valve directly include:
*******MARFAN'S SYNDROME, **********Ehlers–Danlos syndrome, ankylosing spondylitis and systemic lupus erythematosus. In acute cases of aortic insufficiency, the main causes are infective endocarditis ,aortic dissection or trauma.Rate this question:

A 74-year-old Caucasian female presents to her family physician for evaluation of recurrent episodes of chest pain, shortness of breath with exertion, and lightheadedness. Two weeks earlier she experienced an episode of syncope while walking up the stairs of her house. Doppler ultrasonography reveals a heavily calcified aortic valve. The image below represents gross appearance of the patient’s heart. Which of the following is the most likely diagnosis?
- A.
Aortic stenosis of rheumatic heart disease etiology
- B.
Aortic stenosis of luetic etiology
- C.
Aortic stenosis after subacute bacterial endocarditis
- D.
Calcific stenosis of congenitally bicuspid valve
- E.
Senile calcific aortic stenosis
Correct Answer
E. Senile calcific aortic stenosisExplanation
The most likely diagnosis for this patient is senile calcific aortic stenosis. This is supported by the patient's age (74 years old) and the presence of heavily calcified aortic valve on Doppler ultrasonography. Senile calcific aortic stenosis is a common degenerative condition that occurs with aging, leading to narrowing of the aortic valve and symptoms such as chest pain, shortness of breath, and lightheadedness. The other options, such as aortic stenosis of rheumatic heart disease etiology, aortic stenosis of luetic etiology, aortic stenosis after subacute bacterial endocarditis, and calcific stenosis of congenitally bicuspid valve, are less likely given the patient's age and clinical presentation.Rate this question:

The lesion shown in PICTURE below was observed at autopsy of a 35-year-old African American male, intravenous drug user who died 3 days after an acute febrile illness. What laboratory test finding is most likely to be found in the patient’s medical record?
- A.
Elevated anti-streptolysin–O titer
- B.
High serum c-ANCA titer
- C.
High p-ANCA titer
- D.
Positive culture for Staphylococcus aureus
Correct Answer
D. Positive culture for StapHylococcus aureusExplanation
The given scenario describes a patient who died after an acute febrile illness, and the lesion observed at autopsy suggests an infection. The most likely finding in the patient's medical record would be a positive culture for Staphylococcus aureus, indicating that the patient had a Staphylococcus aureus infection. The other options, such as elevated anti-streptolysin-O titer, high serum c-ANCA titer, and high p-ANCA titer, are not specifically related to Staphylococcus aureus infection and are less likely to be found in this patient's medical record.Rate this question:

A 34-year-old Caucasian male is brought to the emergency room with shortness of breath and heart palpitations. His past medical history is significant for a ventricular septal defect. Physical examination reveals cyanosis, pitting edema of the lower legs, distended jugular veins, and hepatosplenomegaly. Heart examination reveals harsh holosystolic murmur and thrill at the left sternal border. Which of the following complications has most likely developed in this patient?
- A.
Eisenmenger syndrome
- B.
Atrial fibrillation
- C.
Ventricular fibrillation
- D.
Myocardial infarction
Correct Answer
A. Eisenmenger syndromeExplanation
The patient's presentation of cyanosis, pitting edema, distended jugular veins, and hepatosplenomegaly, along with a ventricular septal defect and a harsh holosystolic murmur and thrill at the left sternal border, is consistent with Eisenmenger syndrome. Eisenmenger syndrome is a complication of congenital heart defects, such as a ventricular septal defect, where there is a reversal of shunt flow due to increased pulmonary vascular resistance. This leads to cyanosis and the development of right-sided heart failure. Therefore, Eisenmenger syndrome is the most likely complication in this patient.Rate this question:

A 56-year-old Caucasian man presents with recurrent precordial pain and frequent episodes of lightheadedness, muscle weakness and feeling faint. The patient reports that the symptoms first occurred three years ago and then gradually progressed. Physical examination reveals a heart rate of 88 bpm, BP of 130/69 mm Hg, a systolic "thrill" at the second right intercostal space, S4, and diminished S2 and crescendo-decrescendo systolic murmur over the aorta. What type of carotid pulse is most likely to be found in this patient?
- A.
Pulsus alternans
- B.
Pulsus parvus and tardus
- C.
Pulsus paradoxus
- D.
Pulsus bigeminus
Correct Answer
B. Pulsus parvus and tardusExplanation
pulsus tardus et parvus, also pulsus parvus et tardus, slow-rising pulse and anacrotic pulse, is a sign where, upon palpation, the pulse is weak/small (parvus), and late (tardus) relative to its usually expected character.
It is seen in aortic valve stenosis.
Typical findings in aortic stenosis include a narrow pulse pressure, left ventricular hypertrophy, a harsh late-peaking systolic murmur heard best at the right second intercostal space with radiation to the carotid arteries, and a delayed slow-rising carotid upstroke (pulsus parvus et tardus).[Rate this question:

Squatting has which of the following cardiovascular effects?
- A.
It has the opposite effect of passive leg raising
- B.
It decreases the murmur of mitral regurgitation
- C.
It decreases the murmur of ventricular septal defect
- D.
It increases the murmur of aortic insufficiency
Correct Answer
D. It increases the murmur of aortic insufficiencyExplanation
Squatting increases thoracic pressure, decreasing right to left shunting. Aortic insufficiency (AI), also known as aortic regurgitation (AR), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle.Rate this question:
