Objective:
We assessed the feasibility of a facilitated, briefly occlusive, sutureless coronary anastomosis technique in which side-to-side preglued (octylcyanoacrylate adhesive) bounded walls were opened by a conventional arteriotomy.
Methods:
In low-flow (prothrombotic milieu,
Results:
Coronary occlusion lasted a median of 1.6 minutes (15th-85th percentile 1.4-1.8 minutes), and anastomosis construction required a median of 5.5 minutes (15th-85th percentile 4.2-6.5 minutes). At 5 weeks all anastomoses were fully patent (FitzGibbon grade A), with an angiographic appearance similar to an end-to-side anastomotic configuration.
Conclusions:
The briefly occlusive adhesive anastomosis technique proved to be feasible in off-pump bypass surgery in the pig even under prothrombotic low bypass graft flow conditions (
