Abstract
Objective:
Minimally invasive combined mitral and aortic valve surgery is still uncommon. We report our experience performing multiple valve procedures through a right-sided minithoracotomy.
Methods:
We present an observational case series with a retrospective analysis of 38 patients who underwent double valve surgery through right anterior thoracotomy from November 2013 to November 2023.
Results:
The median age of our population was 72 years, and 61% were female patients. The median EuroSCORE II was 2.27. Three patients (7.9%) had redo operations. The median cardiopulmonary bypass (CPB) and cross-clamp times were 98 and 85 min, respectively. No conversion to full sternotomy was necessary. In-hospital mortality was 2.6% (1 patient); the patient died of septic shock and consequent multiorgan failure. Of the patients, 53% required transfusions with packed blood cells. Postoperative atrial fibrillation was observed in 12 patients (32%), and 2 patients (5.2%) required pacemaker implantation due to third-degree atrioventricular block. Also, 1 stroke (2.6%) and 1 rethoracotomy for bleeding were observed. The median ventilation time was 10 h. The median intensive care unit and postoperative length of stay were 2 days and 7.5 days, respectively. Survival at 1, 3, 5, and 10 years was 93.8%, 86.3%, 86.3%, and 77.2%, respectively, with a median follow-up time of 6.5 years. Freedom from reintervention at 1, 3, 5, and 10 years was 96.8%, 89.5%, 85.0%, and 69.5%, respectively, with a median follow-up time of 5.7 years.
Conclusions:
In our experience, a minimally invasive approach for combined aortic and mitral valve surgery is safe and feasible, with acceptable CPB and cross-clamp times and good outcomes. Therefore, it can be an attractive option for patients with double valve diseases.
