Abstract

Objective: Minimally invasive aortic valve replacement (MIAVR) procedures have been found to have good short-term results. However, no known reports regarding outcomes of MIAVR via a right lateral minithoracotomy (LT) approach over longer terms have been presented. The aim of the present study was to analyze the midterm outcomes of the use of MIAVR with the right LT approach over an 8-year period.

Methods: Between September 2014 and February 2023, MIAVR was performed for 348 patients with severe aortic valve stenosis and regurgitation at our hospital. Operative mortality, all-cause mortality, and valve-related events were retrospectively examined.

Results: The mean patient age was 72.3 ± 10.9 years, while 78 patients (22.4%) were more than 80 years old. Surgical, cardiopulmonary bypass, and cross-clamp times were 194.7 ± 43.2, 118.6 ± 28.7, and 89.4 ± 23.3 min, respectively. The 30-day mortality rate was 0.3%. The mean follow-up period was 35.6 ± 25.9 months. Overall survival shown by Kaplan-Meier analysis at 1, 3, and 5 years was 96.4%, 90.3%, and 83.2%, respectively, and freedom from valve-related events at those time points was noted in 100%, 99.5%, and 96.9% of the cases, respectively.

Conclusions: MIAVR via a right LT approach was found to be associated with excellent short-term and midterm outcomes and is considered to have the potential to become an established surgical option.
