Triple Arterial Minimally Invasive Direct Coronary Artery Bypass Grafting: Step-By-Step Technique Report

Minimally invasive direct coronary artery bypass grafting (MIDCAB) has considerable benefits over the conventional coronary artery bypass grafting procedure. This case report presents the MIDCAB procedure in a multivessel coronary disease using triple arterial grafts and four arterial anastomoses. The initial anastomosis was made between the left intrathoracic mammary artery (LIMA) and the radial artery (RA), as an end-to-side "T" graft. Next, the RIMA was used to left anterior descending anastomosis. The first obtuse marginal (OM1) branch was grafted to allow LIMA-OM1 side-to-side anastomosis. Then, with the diagonal branch (Dg) opened, the formation of a "jumping" anastomosis was made using LIMA-OM1-Dg. The posterior descending artery (PDA) was used to create a LIMA-RA-PDA.
