Background:
Hybrid coronary revascularization combines minimally invasive coronary artery bypass grafting and catheter-based interventions. This treatment option represents a viable alternative to both open multivessel coronary bypass surgery through sternotomy and multivessel percutaneous coronary intervention. The surgical component of hybrid coronary intervention can be offered in a completely endoscopic fashion using robotic technology. We report on one of the largest series to date.
Methods:
From 2001 to 2011, 226 patients (age, 61 years [range, 31 to 90 years]; 77.0% male; EuroSCORE, 2 [range, 0 to 13]) underwent hybrid coronary interventions on an intention-to-treat basis. Robotically assisted procedures were performed using the daVinci, daVinci S, and daVinci Si surgical telemanipulation systems (Intuitive Surgical, Inc, Sunnyvale, CA) and included 147 single, 72 double, and 7 triple endoscopic coronary artery bypass grafting procedures. Surgery was carried out first in 160 cases (70.8%), percutaneous coronary intervention was carried out first in 38 cases (16.8%), and 28 patients underwent simultaneous operations in a hybrid operating room (12.4%). Drug-eluting stents were used in 70.0% of the patients.
Results:
Hospital mortality was 3 of 226 patients (1.3%), and hospital stay averaged 6 days (range, 3 to 54 days). Patients walked outside 7 days (range, 3 to 97 days) postoperatively and performed general household work 14 days (range, 7 to 180 days) postoperatively. Full activity was resumed at 42 days (range, 7 to 720 days). Five-year survival was 92.9%, and 5-year freedom from major adverse cardiac and cerebral events was 75.2%. At 5 years, 2.7% of bypass grafts and 14.2% of percutaneous coronary intervention targets needed reintervention.
Conclusions:
Robotically assisted hybrid coronary intervention enables surgical treatment of multivessel coronary artery disease with minimal trauma. Perioperative results and intermediate-term outcomes meet the standards of open coronary artery bypass grafting. Recovery time is short, and reintervention rates are acceptable.
