SECTION 1: CARDIOVASCULAR PHYSIOLOGY & PATHOLOGY Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 68-year-old man with long-standing hypertension presents for a routine
echocardiogram. The parasternal long-axis view reveals a septal wall thickness of 14
mm and posterior wall thickness of 13 mm, with a normal left ventricular cavity size and
preserved ejection fraction. Systolic anterior motion of the mitral valve is not seen.
A. Concentric left ventricular hypertrophy with preserved systolic function ✓ CORRECT
B. Dilated cardiomyopathy with eccentric remodeling
C. Hypertrophic obstructive cardiomyopathy
D. Acute myocardial infarction with compensatory hypertrophy
Correct Answer: A
Rationale: Chronic pressure overload from hypertension produces concentric
hypertrophy characterized by increased wall thickness with normal cavity size and
preserved systolic function. Hypertrophic obstructive cardiomyopathy is unlikely
,because there is no systolic anterior motion or asymmetric septal hypertrophy, and
dilated cardiomyopathy would show ventricular dilation rather than normal cavity
dimensions.
Question 2 of 50
A 54-year-old woman with a history of rheumatic fever as a child is referred for
echocardiography after her physician noted a diastolic murmur. The echo demonstrates
thickened mitral valve leaflets with a hockey-stick deformity of the anterior leaflet and
restricted opening.
A. Mitral valve prolapse with myxomatous degeneration
B. Rheumatic mitral stenosis with commissural fusion ✓ CORRECT
C. Papillary muscle rupture from prior infarction
D. Mitral annular calcification causing functional stenosis
Correct Answer: B
Rationale: The hockey-stick deformity of the anterior mitral leaflet and restricted
opening are pathognomonic for rheumatic mitral stenosis resulting from commissural
fusion and leaflet thickening. Mitral valve prolapse would demonstrate excessive leaflet
motion into the left atrium during systole, not diastolic restricted opening.
Question 3 of 50
During a transesophageal echocardiogram on a 72-year-old man undergoing evaluation
for cryptogenic stroke, the operator visualizes the interatrial septum in the bicaval view.
A thin, mobile membrane with a small central defect is seen dividing the right atrium.
A. Atrial septal defect type secundum
B. Patent foramen ovale with aneurysmal septum
C. Chiari network remnant of the right sinus venosus valve ✓ CORRECT
D. Amplatzer septal occluder device embolization
Correct Answer: C
, Rationale: A Chiari network appears as a thin, highly mobile filamentous structure in the
right atrium and represents a remnant of the embryonic right sinus venosus valve; it is a
benign finding but can be mistaken for pathological structures. A patent foramen ovale
would be visualized at the fossa ovalis rather than as a free-floating membrane in the
right atrial cavity.
Question 4 of 50
A 45-year-old marathon runner presents with exertional dyspnea. Resting
echocardiography shows a left ventricular end-diastolic diameter of 58 mm, end-systolic
diameter of 38 mm, and an ejection fraction of 62%. The left ventricular mass is at the
upper limits of normal.
A. Pathological eccentric hypertrophy from volume overload
B. Dilated cardiomyopathy with early systolic dysfunction
C. Concentric remodeling from chronic pressure overload
D. Physiologic athlete's heart with normal diastolic function ✓ CORRECT
Correct Answer: D
Rationale: Endurance athletes commonly develop physiologic cardiac remodeling with
mild ventricular dilation, increased stroke volume, and preserved or supranormal
systolic function that normalizes with deconditioning. Pathological dilation would be
accompanied by reduced contractility or wall thinning, neither of which is present in this
scenario.
Question 5 of 50
A 78-year-old woman with a history of metastatic breast cancer develops sudden onset
of dyspnea and hypotension. A bedside echocardiogram reveals a large circumferential
echo-free space surrounding the heart, with right atrial diastolic collapse and ventricular
interdependence.
