Abstract

This was a hospital-based cohort study including 45 retrospective patients who underwent minimally invasive mitral valve repair with endoscopic support at Hanoi Heart Hospital from January 2018 to December 2020, with prolonged postoperative follow-up. average 16.4 months. The mean age was 49 ± 12.5 years old. The male/female ratio is approximately 1:1. Patients with mitral valve repair included 43 degenerative valves, 2 post rheumatic valves. The main mechanism is damage to the posterior leaves (34 cases), the second is damage to both the anterior and posterior leaves in 7 cases; simple anterior leaf lesions include 4 cases. Cardiopulmonary bypass and aortic clamp times were 164 ± 34 and 93 ± 19  minutes. Mitral valve reshaping techniques include: annuloplasty 100% , leaflet  resection 48.9% , folding 24.4%, neochordae implantation 20%, edge -to- edge 13.3%. Overall, in-hospital and 30-day mortality were 0%. We encountered 4 complications including 2 cases of bleeding requiring reoperation, 1 case of 1 pleural effusion (2.2%), 1 case of postoperative thigh infection (2.2%). The ICU length of stay was 2.5 ± 0.7 days, and average time to extubation was 18.9 ± 7.5 hours. All 45 cases were successfully operated, there were no cases that had to widen the thoracotomy or sternotomy. The success rate of mitral valve repair is high. (95.6%).
