Less invasive multivessel coronary artery bypass grafting: now is the time

Abstract

Purpose of review Less invasive multivessel coronary artery bypass grafting techniques have seen a progressive evolution over the last two decades. In their current state, they are easily reproduced and applicable to most patients requiring multivessel revascularization. The purpose of this review is to highlight their importance among a spectrum of evolving therapies and the accruing evidence in their favour. Recent findings The first large dual center experience with minimally invasive coronary artery bypass grafting (MICS CABG) demonstrated the feasibility of performing multivessel surgical revascularization without the need for sternotomy or cardiopulmonary bypass. Subsequent angiographic studies to assess graft patency showed excellent early results. Studies comparing MICS CABG to conventional CABG demonstrate faster recovery while reducing hospitalization and cost. Summary Multivessel less invasive coronary artery bypass grafting is basically limited to two procedures, MICS CABG and robotically assisted totally endoscopic CABG (TECAB). MICS CABG has evolved as a procedure that preserves the safety and efficacy of conventional CABG while avoiding the associated morbidity. It is reproducible, versatile and holds promise as the procedure of choice for multivessel coronary revascularization in the future. TECAB is likely the pinnacle of minimally invasive coronary surgery, the growth of which is hindered by widespread acceptance and industry involvement.
