Authors' conclusion
In patients with class I obesity, the robotic approach in comparison to sternotomy was associated with lower transfusion rates, shorter hospitalization, and comparable operative mortality and long-term survival relative to sternotomy. Although 30-day readmission was numerically higher among robotic patients, most events were minor and managed without intervention.
Study context
- Population
- Patients with class I obesity (body mass index 30–34.9 kg/m²) undergoing mitral valve (MV) repair, excluding mitral stenosis, active endocarditis, prior sternotomy, or concomitant procedurespatients with class I obesity who underwent MV repair, 429 remained after exclusions, matched 132 per group · after exclusions 429 · robotic (matched) 132 · sternotomy (matched) 132
- Participants
- 880 patients
- Comparison
- robotic vs sternotomy MV repair in patients with class I obesity
- roboticn = 132
- sternotomyn = 132
