The expanded role of minimally invasive coronary grafting.

The evolution of minimally invasive direct coronary artery bypass (MIDCAB) grafting has extended the role of this approach for limited coronary revascularization. MIDCAB techniques can now be used to address isolated stenoses in the inferior and lateral coronary distributions. MIDCAB techniques are increasingly being used in the reoperative setting, and multiple vessels can be bypassed during a single operation. This article reviews the expanded role of MIDCAB grafting in the treatment of coronary artery disease.
