Minimally invasive approaches to mitral valve repair have demonstrated equivalent technical outcomes and more rapid recovery when compared with traditional sternotomy. These techniques have been widely accepted for mitral insufficiency and stenosis. The utilization of minimally invasive techniques in the presence of left ventricular (LV) dysfunction has been controversial. We hypothesized that minimally invasive mitral valve surgery could be safely performed in the presence of compromised myocardial function, thereby minimizing recovery time. ⋯ Minimally invasive, port-access, mitral valve surgery can be safely performed with minimal morbidity and mortality in the presence of cardiomyopathy. This approach may be considered in patients with isolated mitral valve pathology and LV dysfunction in an experienced center.
