Late results of mitral valve repair for mitral regurgitation due to degenerative disease

Mitral valve repair with a malleable bovine pericardium ring

“…This permitted the achievement of a better result, 65% of the patients passing to functional class I with recovery of left ventricular geometry and mechanical function of the mitral valve, as is also reported in the literature 26,28,34,35 . A follow-up period of 16 months showed a survival ratio of 93.8%; other studies, with lower 29 or equal 36 follow-up periods, reported 98% indexes.…”

“…David et al 35 , using a complete, malleable ring in patients with degenerative valve pathology, found 95±2% free from reoperation for more than 8 years. They concluded that only an advanced degree of myxomatous alterations was related to a greater risk of reoperation.…”

“…A follow-up period of 16 months showed a survival ratio of 93.8%; other studies, with lower 29 or equal 36 follow-up periods, reported 98% indexes. Studies with follow-up periods of five 26,28 , eight 35 and 16 34 years, reported survival rates of respectively, 90 to 98.8±1.2%, 88±4%, and 76.1±-3.1%. It is common to find valve repair leading to a higher survival rate in comparison with valve replacement 37 .…”

“…This places the valve rather than the type of technique employed as the probable responsible factor for this complication. Thromboembolism also appears to be related, along with the cause of Mitral valvuloplasty with a malleable bovine pericardium ring volume 75, (nº 5), 2000 the lesion, to preoperative risk factors, rather than to the surgical procedure proper 34,35 .…”

Plastia valvar mitral na doença cardíaca reumática e degeneração mixomatosa: estudo comparativo

“…Essa cirurgia possui resultado bom e reprodutível, e tem a vantagem de preservar a valva nativa funcionante, evitando os problemas associados à prótese. Em tais circunstâncias, entre 80% e 95% dessas valvas podem ser reparadas (2)(3)(4) .…”
