Less invasive coronary artery bypass grafting: without cardiopulmonary bypass and via reduced surgical access

摘要

The beating heart creates two formidable obstacles to coronary artery bypass grafting (CABG): the motion of the coronary target site hampers accurate anastomosis suturing; and, to reach posterior anastomosis sites, the beating heart needs to be dislocated which causes a pre- cipitous drop in arterial pressure. The use of cardiopulmonary bypass and crystalline car- Dioplegia provides the cardiac surgeon with a perfectly still Surgical field, absence of blood in the target area, and free- Dom to manipulate the heart liberally to expose all major Coronary branches.
