Objective: Safety and sustainability are key elements of a robotic mitral valve (MV) program at any stage of development. Challenges include the positioning of the surgeon at the robotic console, increasing patient complexity, and upstream administrative staffing difficulties. We instituted a systems approach to maximize patient safety and maintain robotic service viability. Methods: A single dedicated robotic operating room (OR) was equipped as a microsystem with team training in the operative steps, ergonomics, digital tools, and an explicit culture of safety. Outcomes of all robotic mitral procedures including concomitant procedures in the microsystem OR by a single surgeon were retrospectively reviewed. Results: From January 2014 through December 2023, 1,529 consecutive MV patients were operated with an endoscopic robotic approach. Ten patients (0.65%) were converted to conventional approaches. Overall, 1,300 MV repairs (85%) were performed with residual MV regurgitation of none to trace in 1,205 patients (92.7%), mild in 92 patients (7.1%), and moderate in 3 patients (0.23%). MV replacements were performed in 229 patients (15%) with no paravalvular leaks. Mortality was 0.08% in the repair group and 0.87% in the replacement group. No deaths have occurred in the last 38 months. Stroke occurred in 0.31% of repair patients and 1.3% of replacement patients. One patient developed transient renal failure. Conclusions: Organization of the robotic OR as a microsystem is associated with surgical efficacy and very low morbidity and mortality. A comparable microsystem approach using all or select components may promote safety and sustainability for robotic MV programs at all levels. Visual abstract
