Objective
To summarize the 7-year surgical experience with totally endoscopic coronary artery bypass grafting (TECAB) and demonstrate the long-term follow-up results of the graft patency.
Methods
Between March 2007 and November 2015, a total of 114 consecutive patients ( 96 male) at a mean age of 58 years (range, 36 to 78 years) and EuroSCORE of 1.1±1.3 underwent off-pump TECAB with da Vinci Surgical System (Intuitive Surgical, USA) in our institution. Skeletonized left internal mammary artery (LIMA) conduit was used to graft LAD and the blood flow in LIMA graft was measured with Medistim VeriQC system (Medistim ASA, Norway). The patients were followed up after surgery and the coronary angiography or CT angiogram (CTA) was performed to evaluate LIMA graft patency.
Results
All cases (n=114) were successfully performed by single console surgeon (Gao C.) with LIMA graft to LAD (100%). There was no operative death or conversion to median sternotomy. The mean operation duration was 219 ± 58 min. The blood flow of LIMA graft was (36.8±18) ml/min after TECAB. No major complication was observed. The postoperative ventilation time was 13.9 ± 4.0 hours. The chest draining volume was 417.4 ±274.8 ml. Coronary angiography or CTA showed 100% graft patency before discharge. During the follow-up, LIMA graft patency was 98.8% at 1 year, 97.8% at 2 years after surgery, and 97.1% at 3 to 5 years after surgery.
Conclusions
Off-pump TECAB using LIMA to graft LAD is safe and effective procedure and the long-term graft patency is excellent.
