An unusual complication after chordal sparing mitral valve replacement.
Clinical Summary A 44-year-old man with cardiac failure was admitted to our clinic for increasing dyspnea. Transesophageal echocardiography showed severe mitral regurgitation with a prolapse of the anterior leaflet. Aortic regurgitation was referred to as mild. End-diastolic diameter was 73 mm, end-systolic diameter was 47 mm, and ejection fraction was calculated to be 0.50. Catheterization rev...
متن کاملOutcomes of Mitral Valve Repair: Quadrangular Resection versus Chordal Replacement
BACKGROUND Mitral valve repair for posterior mitral leaflet (PML) prolapse has been considered to be a standard treatment because of its high success rate and high level of patient satisfaction. The aim of this study was to evaluate the clinical results of two different techniques of PML prolapse, quadrangular resection (QR) and chordal replacement (CR). MATERIALS AND METHODS The subjects con...
متن کاملTranscatheter Mitral Valve Replacement With a Novel Dual Stent Bioprosthesis.
There has been great interest in transcatheter mitral valve replacement (TMVR) as a potential therapy for high-risk patients with severe mitral regurgitation, with several distinct device systems undergoing first-in-man clinical studies. The Intrepid TMVR (Medtronic Inc, Redwood City, CA), designed for transapical delivery, comprises 2 interconnected self-expanding nitinol stents: (1) an inner ...
متن کاملSutureless aortic valve replacement in stentless bioprosthesis failure.
Reoperation for a failed stentless bioprosthesis is an extremely challenging procedure due to severe adhesion around the previous stentless graft and the severely calcified aortic root. Although rarely the subject of reports in the literature, sutureless aortic valve replacement allows a fast and simple implantation, which decreases the risk of cardiac ischaemia and cardiopulmonary bypass. Here...
متن کاملEmergency transapical mitral valve-in-valve implantation for bioprosthesis failure: transapical implantation of an Edwards Sapien-XT in a dysfunctional mitral bioprosthesis in a critical patient
Background: Valve-in-Valve (VIV) Transcatheter Aortic Valve Replacement (TAVR) is now the treatment of choice in high-surgical-risk patients with failing aortic bioprosthesis. Although less performed, VIV-Transcatheter Mitral Valve Replacement (TMVR) is a valid treatment option for selected high-risk patients with degenerated mitral bioprostheses. Several cases of elective ViVTAVR and -TMVR hav...
