A new instrument for the immobilization and hemostasis of an anastomotic site during off-pump bypass is described. The instrument called "MIDCAB doughnut" was used safely and accurately in 31 patients who underwent MIDCAB without CPB. In these, the instrument was applied in 44 anastomotic sites on the beating heart (30 left anterior descending, 7 right coronary, and 7 obtuse marginal arteries). It can make an operative field motionless and bloodless without distal snaring, because of air sucked fixation of an entire circuit of the anastomotic site. There was no operative and hospital deaths. Postoperative angiography revealed a 100% patency rate of the grafts. MIDCAB doughnut can improve a quality of the anastomosis during beating bypass surgery.

Objectives: We have studied the results of 402 consecutive cases of beating heart coronary artery bypass grafting (CABG) and evaluated the usefulness of gastroepiploic artery (GEA) composite grafts.
Methods: Between March 1993 and August 2001, 402 patients underwent beating heart CABG. They were 321 male and 81 female patients, aged 17 to 88 (mean 66) years.

A new instrument for the immobilization and hemostasis of an anastomotic site is described for use during minimally invasive off-pump direct coronary artery bypass (MIDCAB). The mechanism is based on air suction of the heart surface. The instrument is unique in that it can avoid direct temporary of the distal end of the coronary artery to control bleeding.
