Intermediate-Term Patency of Saphenous Vein Graft With a Clampless Hand-Sewn Proximal Anastomosis Device After Off-pump Coronary Bypass Grafting

Intermediate-term angiographic follow-up demonstrate an acceptable SV patency rate after OPCAB. The SV patency rate with a clampless device for proximal anastomosis is comparable with that with partial clamping during the first postoperative year.
