Background
Mitral valve surgery through a right mini-thoracotomy (RMT) is gaining widespread acceptance and has become routine in many centers. Although technically challenging, its potential benefits include a decreased postoperative bleeding and pain, and a faster recovery. We report our early experience of mitral valve surgery through a right mini-thoracotomy.
Methods
From October 2018 to October 2021, a total of 101 patients underwent a mitral valve surgery through RMT in our center. A complete minimally invasive procedure was achieved in all patients. Preoperative diagnostics were degenerative mitral valve insufficiency (n=78), rheumatismal mitral valve disease (n=10), endocarditis (n=7), with one case of ischemic mitral valve insufficiency.
Results
The male/female ratio was 67/44. The mean age was 64 years (ranging from 33 to 86). The mean Euroscore II score was 2.4 (ranging from 1 to 17). There were 37 cases of mitral valve replacement, and 64 cases of mitral valve repair. Five cases were associated with a tricuspid valve annuloplasty, 2 cases with closure of an atrial septal defect, and one case with a combined aortic valve replacement. The mean cross-clamp and by-pass times were 95 (56min -178min), and 140 (97 min -239 min) respectively. One case was performed without cross-clamping on a fibrillating heart. There were 9 surgical revision for bleeding, and one for a femoral artery pseudoaneurysm at the canulation site. 30-day survival was 95%.
Conclusions
Although at the beginning of our program with a learning curve period; Minimal invasive mitral valve surgery through RMT is a safe and reproducible approach in our center.
