BACKGROUND AND AIM OF THE STUDY: The debate on the usefulness of the minimally invasive approach in mitral valve surgery is still open. The aim of this study is to describe a single-center case series of all comers undergoing minimally invasive mitral valve reconstruction.
METHODS: From 2010 to 2019, all the data recorded in the medical records of 893 consecutive patients undergoing mitral valve reconstruction through a right mini-thoracotomy were retrospectively collected. All patients were contacted by telephone for remote evaluation and integration of echocardiographic information on surgical results.
RESULTS: Mean age was 62.2 ± 14.5; 447 (50%) were female and mean log EuroSCORE was 2.5 ± 2.8%. At a mean follow-up of 4.1 ± 2.2 years (median 3.9), a total of 24 deaths (2.68%) were recorded. Twenty-four patients required rehospitalization for cardiac causes, 13 (1.4%) patients had at least moderate mitral insufficiency on follow-up echocardiography and, of these, seven patients underwent reoperation (0.8%). The cumulative hazard showed that 8.3% of patients experienced at least one event at 5 years. NYHA class improved significantly with 874 patients in NYHA class I, 13 in NYHA class II, 6 in NYHA class III, and 0 in NYHA class IV at last follow-up (p < .001 from baseline as reference point).
CONCLUSIONS: In a high-volume center, mitral valve surgery using a minimally invasive approach is a feasible treatment option for all-comers and is associated with excellent results that are maintained at clinical and echocardiographic follow-up.
