Predictors, Causes, and Consequences of Conversions in Robotically Enhanced Totally Endoscopic Coronary Artery Bypass Graft Surgery

Conversion in TECAB is primarily learning curve-dependent and associated with increased morbidity, but does not significantly affect hospital mortality. Both nonconverted and converted patients show good long-term survival, which is comparable to patients undergoing open sternotomy coronary artery bypass grafting. Long-term freedom from angina or freedom from major adverse cardiac and cerebral events is not influenced by conversion.
