Echocardiogram Cardiac Pathology and Disease Recognition 2

Question 1

Which echocardiographic feature best differentiates constrictive pericarditis from restrictive cardiomyopathy?

Accepted Answer

Septal bounce and respiratory variation in mitral inflow >25%

Answer

Septal bounce and >25% respiratory variation in mitral inflow velocities are hallmarks of constrictive pericarditis, reflecting interventricular dependence.

Question 2

A vegetation on the aortic valve with associated aortic regurgitation is most consistent with which diagnosis?

Accepted Answer

Infective endocarditis

Answer

Valvular vegetations with associated regurgitation are the classic echocardiographic hallmarks of infective endocarditis.

Question 3

On echocardiography, which finding is pathognomonic for cardiac tamponade physiology?

Accepted Answer

Right ventricular diastolic collapse with respiratory variation in tricuspid inflow

Answer

RV diastolic collapse combined with respiratory variation >40% in tricuspid inflow is pathognomonic for cardiac tamponade physiology.

Question 4

Ebstein's anomaly is best characterized echocardiographically by which finding?

Accepted Answer

Apical displacement of the tricuspid valve leaflets into the RV

Answer

Ebstein's anomaly is defined by apical displacement of the septal and posterior tricuspid leaflets, effectively 'atrialized' the inlet portion of the RV.

Question 5

Which echocardiographic feature best identifies a rheumatic mitral stenosis?

Accepted Answer

Diastolic doming (hockey-stick deformity) of the anterior mitral leaflet with restricted posterior leaflet

Answer

Rheumatic mitral stenosis classically shows diastolic doming (hockey-stick) of the anterior leaflet with restricted posterior leaflet motion due to commissural fusion.
