A rare case series of mechanical prosthetic heart valve structural deterioration presented as severe mitral regurgitation

Abstract

Objective: Structural valve deterioration in the form of stenosis or regurgitation or both though being a rare complication with newer generation mechanical heart valves can occur and can be critical. Case presentation: We report two cases of severe mitral regurgitation due to structural deterioration of TTK Chitra mechanical heart valve (disc fracture) in mitral position. Conclusion: In patients with mechanical heart valve prosthesis who present with acute decompensated heart failure or congestive heart failure, structural valve deterioration should be suspected and early diagnosis and treatment is the key to success in structural valvular deterioration.
