Percutaneous Treatment of Mitral Paraprosthetic Regurgitation: an Alternative to Surgery

Paraprosthetic regurgitation occurs in approximately 7%–17% of patients undergoing mitral valve replacement and 2%–10% of patients undergoing aortic valve replacement1,2. Typically, this regurgitation is discrete and does imply major clinical complications; however, when it is moderate or severe, the consequences can be serious, leading to heart failure and/or hemolysis3,4. It is estimated that approximately 1%–5% of cases develop to more clinically severe conditions1,4. The main causes of paraprosthetic regurgitation are calcification of the valvular annulus, infection, suture technique, and size and shape of the prosthesis1,5.
