Early results of total arterial off-pump coronary artery bypass grafting using bilateral internal mammary arteries

Abstract

Background: The optimal coronary artery bypass grafting (CABG) technique is still evolving. This study aimed to evaluate the early results of the total arterial off-pump technique using bilateral internal mammary arteries.

Methods: This study was performed from May 2018 to May 2019 at a cardiac surgery center in India. It included 200 patients with coronary artery disease who had off-pump CABG using bilateral internal mammary arteries. The patients had follow-ups for three months. There were 50 females, and the mean age was 50±10 years.

Results: Conversion to on-pump was required in one case (0.5%). The use of complete vein grafts was needed in three cases (1.5%), and vein graft extension was done for two cases (1%). Intra-aortic balloon pump was used in one case (0.5%). Postoperative re-exploration for bleeding was done in two cases (1%), and sternal dehiscence or deep infection occurred in two cases (1%). A pacemaker was used in one case (0.5%), and postoperative need for dialysis occurred in three patients (1.5%). No operative mortality or postoperative stroke was reported. Redo surgery was required in one patient (0.5%).

Conclusions: Off-pump total arterial revascularization technique using bilateral internal mammary arteries could have an acceptable early outcome.
