,Q1. A patient with severe aortic stenosis (aortic valve area 0.7 cm²) is being evaluated for transcatheter
aortic valve replacement (TAVR). The patient has a history of chronic atrial fibrillation and is on warfarin.
Which of the following peri-procedural anticoagulation strategies is most consistent with current guidelines?
A. Continue warfarin throughout the procedure without interruption
B. Bridge with low-molecular-weight heparin (LMWH) and hold warfarin 3 days pre-procedure
C. Hold warfarin 3 days pre-procedure, no bridging, and restart warfarin post-procedure
D. Switch to direct oral anticoagulant (DOAC) 1 week before procedure
Correct Answer: A. Continue warfarin throughout the procedure without interruption
Rationale: Current guidelines recommend continuing warfarin without interruption for TAVR in patients with atrial
fibrillation, as bridging increases bleeding risk and interruption increases thromboembolic risk. DOACs are not
recommended periprocedurally due to lack of reversal agents and limited data.
Why Wrong:
B - Bridging with LMWH is associated with higher bleeding without thromboembolic benefit in this setting.
C - Holding warfarin without bridging increases the risk of periprocedural stroke in a high-risk patient.
D - Switching to a DOAC is not recommended due to absence of reversal agents and lack of evidence for
safety during TAVR.

Disease. Circulation, 143(5), e72-e227.
Q2. Which of the following hemodynamic profiles is most consistent with severe acute mitral regurgitation?
A. Normal left ventricular end-diastolic pressure, tall V waves on pulmonary capillary wedge pressure, and
preserved ejection fraction
B. Elevated left atrial pressure, prominent V waves, and acute pulmonary edema with normal left ventricular
size
C. Elevated left ventricular end-diastolic pressure, low cardiac output, and dilated left ventricle
D. Normal pulmonary capillary wedge pressure, low cardiac output, and elevated systemic vascular resistance
Correct Answer: B. Elevated left atrial pressure, prominent V waves, and acute pulmonary edema with
normal left ventricular size
Rationale: Acute severe MR causes sudden volume overload into a normal-sized left atrium, leading to elevated left
atrial pressure and prominent V waves. The left ventricle is not yet dilated, and pulmonary edema occurs rapidly.
Option A describes chronic compensated MR, C describes chronic volume overload, D is more consistent with
cardiogenic shock from other causes.
Why Wrong:
A - Normal LVEDP and preserved EF are seen in chronic compensated MR, not acute severe MR.
C - Dilated LV is a feature of chronic MR, not acute MR where the ventricle has not had time to remodel.
D - Normal PCWP is not consistent with acute severe MR; elevated PCWP with V waves is classic.
Reference: Mann, D.L. et al. (2022). Braunwald's Heart Disease, 12th Ed., Ch. 64.
Q3. In a patient with severe mitral stenosis (mitral valve area 1.0 cm²) and atrial fibrillation, which of the
following is the most appropriate initial step to reduce the risk of embolic events?
A. Initiate rate control with beta-blocker and start warfarin with INR target 2.0-3.0
B. Perform direct current cardioversion after transesophageal echocardiogram to exclude left atrial thrombus
C. Start a direct oral anticoagulant (DOAC) without bridging
D. Refer for percutaneous mitral balloon valvuloplasty before any anticoagulation
Correct Answer: A. Initiate rate control with beta-blocker and start warfarin with INR target 2.0-3.0
Rationale: In mitral stenosis with atrial fibrillation, anticoagulation with warfarin (INR 2-3) is indicated due to
high thromboembolic risk. Rate control is also essential. DOACs have not been well studied in rheumatic mitral
stenosis and are not recommended. Valvuloplasty may be considered later but does not address acute embolic risk.
Page 3
, Why Wrong:
B - Cardioversion is not first-line; the patient has persistent AF and requires chronic anticoagulation.
C - DOACs are contraindicated in rheumatic mitral stenosis due to lack of efficacy data.
D - Valvuloplasty does not reduce embolic risk acutely; anticoagulation is needed first.
Reference: Nishimura, R.A. et al. (2014). 2014 AHA/ACC Guideline for the Management of Patients With Valvular Heart
Disease. J Am Coll Cardiol, 63(22), e57-e185.
Q4. A patient with a mechanical mitral valve prosthesis presents with a transient ischemic attack despite
therapeutic INR. Which of the following is the most likely cause?
A. Subtherapeutic INR due to dietary vitamin K fluctuation
B. Pannus formation on the prosthetic valve
C. Infective endocarditis with vegetation
D. Nonbacterial thrombotic endocarditis
Correct Answer: B. Pannus formation on the prosthetic valve
Rationale: Pannus formation (fibrous tissue overgrowth) can cause obstruction or embolism even with therapeutic
INR. It is a common cause of late prosthetic valve thrombosis and embolic events. Subtherapeutic INR would be
excluded by the scenario. Endocarditis is possible but less likely without fever or other signs.
Why Wrong:
A - The scenario states therapeutic INR, so subtherapeutic levels are not the cause.
C - Infective endocarditis typically presents with fever and positive blood cultures.
D - Nonbacterial thrombotic endocarditis is associated with malignancy and hypercoagulable states, not a
common cause in mechanical valves.
Reference: Pibarot, P. & Dumesnil, J.G. (2009). Prosthetic valve thrombosis. Circulation, 119(9), 1253-1262.
Q5. Which of the following valve lesions is most likely to result in a normal or decreased left ventricular
end-diastolic volume due to reduced preload?
A. Chronic aortic regurgitation
B. Chronic mitral regurgitation
C. Chronic aortic stenosis
D. Chronic mitral stenosis
Correct Answer: D. Chronic mitral stenosis
Rationale: Mitral stenosis impedes left ventricular filling, leading to reduced preload and decreased LV
end-diastolic volume. Aortic stenosis increases afterload but preload is typically normal. Regurgitant lesions (AR,
MR) increase LV volume due to volume overload.
Why Wrong:
A - Chronic aortic regurgitation increases LV end-diastolic volume due to volume overload.
B - Chronic mitral regurgitation increases LV end-diastolic volume due to volume overload.
C - Chronic aortic stenosis usually maintains normal LV end-diastolic volume until late stages.
Reference: Mann, D.L. et al. (2022). Braunwald's Heart Disease, 12th Ed., Ch. 63.
Q6. In a patient with severe aortic stenosis and low-flow, low-gradient (LFLG) pattern with reduced ejection
fraction (EF < 50%), which of the following findings would best indicate true severe aortic stenosis versus
pseudosevere aortic stenosis?
A. Doppler velocity index (DVI) < 0.25
B. Aortic valve area < 1.0 cm² on dobutamine stress echocardiography
C. Increase in stroke volume > 20% with dobutamine and calculated valve area remains < 1.0 cm²
D. Mean gradient < 40 mmHg at rest
