OBJECTIVE: Minimally invasive approaches are more frequently used for treatment of valve disease. We analyzed our five year experience in minimally invasive video-assisted (MIVA) mitral valve surgery.
METHODS: From October 2009 to November 2014, 208 patients with mitral valve (MV) disease underwent a MIVA procedure through a small (5 cm) right mini-thoracotomy at the fourth intercostal space. In one hundred and seventy patients MV was repaired (81,73%); overall concomitant procedures were tricuspid valve anuloplasty by ring insertion (n=24), maze procedure (n=3), interatrial defect closure (n=5). A ring was used in all repair procedures; a leafleat resection was performed in thirty three patients (19,4%) and in 22 patients (13%) Gorotex neo-chordae were inserted. Preoperatively mean logistic euroscore was 5,5 (range 1,51-48,86); mean age was 62,42 (range 20-84) there were eleven reoperation (5,2%).
RESULTS: Mean aortic cross-clamp time and cardiopulmonary bypass time were 146 and 103 min. respectively; an Endo-aortic clamp was used in 121 patients (58,2%). Intraoperatively three patients (1,7%) required mitral replacement for valve incompetence. Overall hospital mortality was 2,4% (n=5), re-exploration for bleeding was necessary in 9 cases (4,3%). Two strokes (0,9%) occurred and pacemaker was necessary in 5 patients (2,4%). Mean follow-up time was 27,3 months. During this period two non cardiac deaths occurred. In the repaired group one hundred forty six patients (89%) had no or trivial mitral regurgitation.
CONCLUSIONS: In our experience MIVA for treatment of MV diseases was safe and effective. This technique demonstrates to have good early and mild-term results in MV surgery.
