Minimally Invasive Mitral Valve Surgery: Long-Term (20-Year) Follow-Up After Right Anterolateral Minithoracotomy.

ABSTRACT:

Background

Minimally invasive mitral valve (MV) surgery (MIMVS) through right lateral minithoracotomy has evolved as the standard approach for most patients. Data on long-term functional outcomes, however, are rare. We evaluated long-term outcomes after MIMVS through right minithoracotomy for up to 21.6 years.

Methods

From 1997 to 2017, 301 patients with a median age of 57 years (range, 20-81; 54.5% female) underwent MIMVS through right anterolateral minithoracotomy. Follow-up data were evaluated using Kaplan-Meier analyses and competing risk analysis.

Results

A total of 249 patients (82.7%) underwent MV repair, and 52 (17.2%) received valve replacement. Conversion to sternotomy was required in 2 patients (0.8%), and 2 patients (0.8%) suffered perioperative stroke. Th
