Bons resultados nos procedimentos de implante transcateter valva-em-valva mitral e valva-em-anel mitral

Fundamentos: Válvulas bioprotéticas são cada vez mais implantadas em cirurgias cardíacas abertas. Estas válvulas geralmente falham, resultando na necessidade de uma nova cirurgia cardíaca, com risco elevado de mortalidade. O implante transcateter valva-em-valva mitral (VIVM) pode eliminar a necessidade de reoperação. A implantação transcateter valva-em-valva e valva-em-anel mitral (VIAM) é uma abordagem menos invasiva e,...

Mitral valve repair in moderate ischemic mitral regurgitation

Article Up to 50% of acute myocardial infarctions are associated to mitral regurgitation of some degree and 10% of these cases present, at least, moderate regurgitation. Ischemic mitral regurgitation is associated to an increase of mortality and morbidity. For surgical patients with moderate regurgitation, the benefits mitral valve repair remain unclear.  301 patients were randomized...

Safety and efficacy of Cardiobrand device for percutaneous mitral annuloplasty

The Cadiobrand device is implanted through a transseptal approach and makes a reduction in the mitral annulus area. The study included 24 patients with moderate mitral regurgitation (functional class III- IV) and high surgical risk. The device was successfully implanted in all cases reducing the annular size by 92 % and to the same extent...

MITRAL: First cases of Transcatheter Mitral Valve Implantation (TMVI)

Severe mitral regurgitation is three times more prevalent than aortic stenosis in the elderly population at high risk and poor prognosis if not treated. Fortis mitral valve was designed using several preclinical models and are now tested for the first time in 4 patients resulting in various technical difficulties and finally the death of 3...

Plastic versus mitral valve replacement in ischemic mitral regurgitation

Unlike degenerative mitral insufficiency, ischemic failure is due to an increase in the left ventricular cavity, the loss of its elliptical form, ring dilation and displacement of the papillary muscles leading to the loss of coaptation the leaflets. European and American guidelines suggest the intervention on the mitral valve in patients with ischemic mitral regurgitation...
