Minimally Invasive Mitral Valve Repair for Standalone Secondary Mitral Regurgitation

Chronic secondary mitral valve regurgitation is associated with a poor prognosis. Yet, in contrast to primary mitral regurgitation, there is no clear evidence that a reduction in regurgitation improves survival. The limited availability of data regarding secondary mitral regurgitation has resulted in a low level of evidence for treatment recommendations. We evaluated the influence of minimally invasive mitral valve annuloplasty on survival, freedom from recurrent regurgitation, and other echocardiographic parameters in patients with “standalone” secondary mitral valve regurgitation. The analysis included patients with severe secondary mitral regurgitation, left ventricular function
