Abstract

Mechanical valve dysfunction can be classified as endogenous and exogenous according to the etiology. Endogenous dysfunctions are caused by valve damage or defect, which has become extremely rare with the improvement of design, materials, and manufacture and detection methods in vitro. Exogenous causes include inappropriate selection of prosthesis, technical issues or other complications, such as thrombosis, excessive pannus overgrowth into the prosthetic rim, excessively long knot end, residual chordate tendineae stuck in the prosthetic sewing ring, extremely long residual papillary muscles in left ventricle or calcified tissues under the prosthesis hampering leaflet mobility. We are reporting a case of intermittent malfunction of prosthetic aortic valve [21 mm Medtronic hall mechanical prosthesis] in a 37-year-old female, who underwent Aortic Valve Replacement (AVR) eighteen year back for aortic valve endocarditis and severe Aortic Regurgitation (AR).
