We performed 45 cases of Natural folding plasty without leaflet resection for degenerative mitral regurgitation (MR) between September 2005 and July 2014. Twenty cases of 45 were operated by right small intercostal approach (MICS). There was no operative mortality. No patient had greater than mild MR intraoperative transesophageal echocardiography. The median follow-up was 847 (19~1,747) days. One case needed a second pump run performed without complication. One patient had a reoperation performed for recurrent MR 20 months later. Natural folding plasty for degenerative MR with favorable long term out come in our results. This technique is simple and reproducible for most surgeons. Furthermore, with its simplicity and reversibility, we considered it to be suitable for MICS approach.
