Transcatheter Aortic Valve Implantation in a Failed Perceval Sutureless Valve, Complicated by Aortic Annular Rupture.

As the use of surgically implanted sutureless aortic valves has increased over the past decade, we expect to encounter their failure increasingly in coming years. We describe a case of Perceval aortic valve failure with stent infolding and severe stenosis. This condition was treated with valve-in-valve transcatheter aortic valve implantation and complicated by aortic annular rupture at the site of infolding. This case is important because it outlines the limited experience with valve-in-valve transcatheter aortic valve implantation to treat failed sutureless valves and identifies sutureless valve infolding as a potential risk for annular rupture.

Puisque l'implantation valvulaire aortique sans suture s'est accrue au cours de la dernière décennie, nous nous attendons à rencontrer de plus en plus de défaillances de valves dans les années à venir. Nous décrivons un cas de défaillance de la valve aortique Perceval avec pliage de l'endoprothèse et sténose grave. Le traitement qui consistait en l'implantation valvulaire aortique de type valve-in-valve par cathéter a été compliqué par la rupture de l'anneau aortique au site du pliage. Il s'agit d'un cas important puisqu'il décrit le peu d'expérience en matière d'implantation valvulaire aortique de type valve-in-valve par cathéter dans le traitement des valves sans suture défectueuses et établit que le pliage d'une valve sans suture expose à un risque de rupture de l'anneau.

Hypertrophic cardiomyopathy with intermittent free mitral regurgitation-a surgical dilemma.

We describe the case of a 52-year-old woman presenting with non-ST elevation myocardial infarction, atrial fibrillation, and a new diagnosis of hypertrophic cardiomyopathy. Transesophageal echocardiography following hemodynamic deterioration revealed completely restricted mitral leaflet motion with free mitral regurgitation, and severe left ventricular outflow tract (LVOT) obstruction. Surgical intervention was considered; however, repeat imaging following a period of clinical stability revealed resolution of the findings suggesting a transient ischemic etiology. The case is supported by clinical and echocardiographic images with movie clips, and a discussion of the likely pathology in the context of the underlying condition.
