Minimally invasive aortic valve replacement in morbidly obese patients: outcomes from a cohort study and pooled data analysis.

ABSTRACT:

Background

In the context of cardiac surgery, morbid obesity poses several perioperative challenges. Some surgeons consider obesity a relative contraindication for minimally invasive aortic valve replacement (MIAVR) due to anatomical and technical complexities. Although MIAVR is increasingly used in standard-risk populations, evidence supporting its safety and efficacy in morbidly obese patients remains limited.

Methods

This retrospective cohort consisted of 920 patients who underwent MIAVR via partial upper ministernotomy at a high-volume cardiac surgery center between 2010 and May 2025. Patients were categorized into three groups based on BMI: Class I obesity (BMI 30-35 kg/m²; n = 164), Class II-III obesity (BMI > 35 kg/m²; n = 54), and
