MITRAL VALVE REPAIR-INDICATION AND LATE RESULTS-

In recent years, mitral valve repair has become more widespread because it promises a reduction in both mortality and morbidity compared with valve replacement. As the incidence of rheumatic valve disease has declined in Japan, degenerative disease has become the most common cause of mitral regurgitation (MR), for which repair techniques can be successfully applied. The standard repair techniques, including artifitcial chordal implantation, increase the indications for valve repair to up to 95% of patients with MR and improve the long-term results. The indications for surgical intervention in patients with MR have evolved. Asymptomatic patients are considered for surgery when left ventricular function begins to deteriorate or atrial arrhythmias appear.
