Early outcomes of minimally invasive mitral valve replacement via right thoracotomy at Phu Tho Provincial General Hospital

Key Points

Early outcomes indicate minimally invasive mitral valve replacement is safe and effective for patients with rheumatic heart disease.
Mean cardiopulmonary bypass time was 113.8 minutes, with most patients having favorable outcomes after one month.
Surgical approach via right thoracotomy resulted in a low conversion rate to sternotomy at 2.5%, minimizing complications.
A mean hospital stay of 9 days after surgery suggests satisfactory recovery in a provincial cardiac center.

Abstract

Objective: To evaluate the early outcomes of minimally invasive mitral valve replacement surgery (MIMVR) via right mini-thoracotomy at Phu Tho Provincial General Hospital. Methods: A retrospective descriptive study was conducted on 40 patients who underwent MIMVR between June 2023 and May 2025. Postoperative outcomes were assessed at one-month follow-up. Result: Mean age was 57.8 ± 10.4 with females acounting for 60%; pre-operative NYHA class III-IV in 45% (18 cases); 5% (2 cases) had a Left Ventricle Ejection Fraction below 50%. The pathogenesis of rheumatic heart disease 85%, degeneration 15%. The mean cardiopulmonary bypass time was 113.8 minutes and the mean aortic cross-clamp time was 70.6 minutes. Conversion to sternotomy was required in 2.5% (1 case). The mean mechanical ventilation time and hospital stay were 6,6 hours and 9 days respectively. Conclusion: Minimally invasive mitral valve replacement surgery via right thoracotomy is a safe, effective and seasible method with favorable early outcomes in a provincial-level cardiac center.
