Data from the large national registry maintained by the Society of Thoracic Surgeons indicate that slightly less than 4% of isolated CABG operations involve bilateral internal thoracic artery (ITA) grafts.
Several cases have been reported in which the SAN artery does not arise in the right aortic sinus (20) or originates in a bronchial artery or directly from the internal thoracic artery (21).
The use of left internal thoracic artery (LITA) as a bypass conduit is associated with the highest long term patency rate and greater life expectancy with respect to saphenous vein (SV) and radial artery grafts after coronary artery bypass grafting (CABG) (1).
Use of bilateral internal thoracic artery (BITA) grafts is associated with improved long-term survival (1), reduced incidence of recurrent angina, and decreased cardiac events compared with patients receiving only left internal thoracic artery (LITA) graft (2, 3).
Objective: Postoperative respiratory functions, arterial blood gases, blood loss and clinical outcome following coronary artery bypass surgery (CABG) were assessed in a prospective randomized single-blind (patient-blind) clinical study comparing two different techniques of internal thoracic artery (ITA) harvesting.

The main strategy of coronary artery bypass grafting (CABG) is based on grafting the left internal thoracic artery (LITA) to left anterior descending artery (LAD) and using the saphenous vein graft (SVG) for the remaining affected vessels and anastomosing the grafts proximally to the ascending aorta.
