Abstract

Purpose: The safety and long-term durability of minimally invasive mitral valvuloplasty (MIMVP) remain controversial. This study aimed to compare the perioperative and long-term outcomes of minimally invasive mitral valve surgery (MIMVS) and conventional sternotomy.

Methods: This study included 476 patients who underwent mitral valve surgeries at our institution between January 2011 and December 2023. Patients were classified according to whether they underwent sternotomy: the nonsternotomy (NS: 271 cases) and sternotomy (S: 205 cases) groups. Perioperative and long-term outcomes were compared between the two groups.

Results: The NS group had a lower preoperative age and EuroScore II. In the S group, the left ventricular ejection fraction was lower, while the left ventricular end-systolic diameter and left atrial diameter were larger. Operative time, cardiopulmonary bypass time, and aortic cross-clamp time were longer in the NS group. Postoperative atrial fibrillation, more transfusion, and increased length of hospital stay were more frequent in the S group. The 10-year freedom from reoperation and 10-year survival rates in the NS and S groups were 98.1% vs. 93.6% (p = 0.07) and 94.8% vs. 86.9%, respectively (p = 0.08), with no significant differences.

Conclusion: MIMVP demonstrates noninferior perioperative and long-term outcomes compared with conventional sternotomy.

期刊介绍： Journal of Cardiac Surgery (JCS) is a peer-reviewed journal devoted to contemporary surgical treatment of cardiac disease. Renown for its detailed "how to" methods, JCS''s well-illustrated, concise technical articles, critical reviews and commentaries are highly valued by dedicated readers worldwide. With Editor-in-Chief Harold Lazar, MD and an internationally prominent editorial board, JCS continues its 20-year history as an important professional resource. Editorial coverage includes biologic support, mechanical cardiac assist and/or replacement and surgical techniques, and features current material on topics such as OPCAB surgery, stented and stentless valves, endovascular stent placement, atrial fibrillation, transplantation, percutaneous valve repair/replacement, left ventricular restoration surgery, immunobiology, and bridges to transplant and recovery. In addition, special sections (Images in Cardiac Surgery, Cardiac Regeneration) and historical reviews stimulate reader interest. The journal also routinely publishes proceedings of important international symposia in a timely manner.
