Surgical strategy for video-assisted minimally invasive surgery of multiple valvular diseases

OBJECTIVE: To explore the feasibility and effect of video-assisted minimally invasive surgery for combined heart valvular diseases through an intercostal incision. METHOD: From July 2022 to April 2025, a total of 50 video-assisted minimally invasive combined heart valve surgeries were performed in the Department of Cardiovascular Surgery of the First Affiliated Hospital of Anhui Medical University. Combined heart valve procedures include mitral and tricuspid valve surgery and mitral and aortic valve surgery, as well as large atrial septal defect repair combined with mitral and tricuspid valve surgery. The 4th right intercostal incision along the anterior axillary line was set as the primary access for the surgical procedure of combined mitral and tricuspid valves. The 3rd intercostal incision next to the sternum was set as the primary access for the surgical procedure of combined aortic and mitral valves. The 4th right intercostal incision along the midclavicular line was set as the primary access for the surgical procedure of combined mitral and tricuspid valves concomitant with a large defect of the atrial septal. The perioperative data of patients was collected. RESULTS: All patients underwent the video-assisted minimally invasive surgery completely. A total of 49 patients were discharged as expected except for only 1 older patient who was transferred into a local medical institution for extended rehabilitation due to delayed postoperative awakening. Postoperatively, excellent function of replaced prosthetic valves without paravalvular leaking has been confirmed. Moreover, there was no or less than mild regurgitation for repaired mitral and tricuspid valves. Also, postoperative complications, including III atrioventricular block, renal failure, and severe hypoxaemia, have not been found. CONCLUSION: Video-assisted minimally invasive surgery for combined heart valves is safe and effective with a short-term satisfactory outcome.
