Minimally invasive surgical coronary artery bypass in women

Abstract

Minimally invasive coronary artery bypass grafting (CABG) has emerged as a viable alternative to conventional sternotomy CABG in select patients requiring coronary revascularization. Specific techniques vary, but minimally invasive CABG (i.e., MIDCAB) usually involves revascularization of the left anterior descending (LAD) artery with the left internal mammary artery (LIMA). Minimally invasive CABG can be performed without cardiopulmonary bypass through a small anterior thoracotomy incision with robotic assistance. Use of minimally invasive CABG may offer specific benefits for women requiring revascularization, particularly given that female gender is an independent risk factor for inferior outcomes following CABG. Here we describe how to perform robot-assisted minimally invasive CABG, with a focus on technical modifications aimed at improving outcomes in women.
