A very elegant transcatheter strategy for complicated mitral valve replacement associated with severe mitral annular calcification

摘要: DISCUSSION MAC can pose a significant challenge for even the most experienced surgeons and multiple techniques have been proposed to address this challenging problem.Novel atrial sliding plasties, anterior leaflet transposition, autologous or xenograft patch plasty reported. These extensive procedures require prolonged myocardial ischemic cardiopulmonary bypass times, however, they are associated with not insignificant risk of circumflex artery injury, atrioventricular dissociation, calcific embolization. The patient had severe severely narrowed mitral orifice, limiting surgical options. Because patient’s advanced age, concomitant aortic stenosis,
