Prosthetic perivalvular leak is best described as which of the following?

• A. A complication of artificial heart valve surgery; may present as a heart murmur or severe anemia and CHF
• B. An infectious endocarditis
• C. A type of atrial fibrillation
• D. A normal post-operative finding

Answer: (A)

Prosthetic perivalvular leak is a leakage around a surgically implanted valve due to imperfect sealing at the valve annulus. This is a known complication of artificial heart valve surgery. The leak allows blood to jet around the prosthesis rather than through it, which can produce a new heart murmur and lead to volume overload with heart failure symptoms. Chronic shear from the abnormal flow can also cause hemolytic anemia. It is not infectious endocarditis, which would present with fever and infection signs, nor is it a rhythm disorder like atrial fibrillation, and it is not a normal post-operative finding.
