Late Migration of a Paravalvular Leak Closure Device

Abstract

Paravalvular leak (PVL) is a serious complication of surgical valve replacement, often affecting elderly, multimorbid, high-risk patients. The risk of surgical intervention is often prohibitive in these cases, and so percutaneous PVL closure emerged as a feasible and effective management strategy, with a low complication rate. Specific devices for closure of PVL's are currently not widely available, and so PVLs are closed using generic vascular closure devices, which may result in residual paravalvular regurgitation or even closure device displacement. Although rare, late displacement of the closure device with prosthetic impingement can be life threatening, requiring urgent intervention.We present a case of a seventy-year-old gentleman with rheumatic heart disease and multiple previous mechanical aortic and mitral valve replacements. After repeated admissions for decompensated heart failure, secondary to paravalvular mitral regurgitation, a percutaneous paravalvular leak closure was performed with successful reduction of the leak. He represented 30 days later with cardiogenic shock and multiorgan failure secondary to torrential central mitral regurgitation caused by late displacement of the closure device with mitral prosthesi...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Cardiogenic Shock

Cardiogenic shock is a devastating consequence of acute myocardial infarction and is associated with an extremely high mortality. Here is the latest research.
