A 60-year-old male has three-vessel disease and supraventricular tachycardia which has been refractory to other management. He previously had pacemaker placement and stenting of LAD coronary artery stenosis, which has failed to solve the problem. He will undergo CABG with autologous saphenous vein and an extensive modified MAZE procedure to treat the tachycardia.
He is brought to the cardiac OR and placed in the supine position on the OR table. He is prepped and draped, and adequate endotracheal anesthesia is assured. A median sternotomy incision is made and cardiopulmonary bypass is initiated. The endoscope is used to harvest an adequate length of saphenous vein from his left leg. This is uneventful and bleeding is easily controlled. The vein graft is prepared and cut to the appropriate lengths for anastomosis. Two bypasses are performed: one to the circumflex and another to the obtuse marginal. The left internal mammary is then freed up and it is anastomosed to the ramus, the first diagonal, and the LAD. An extensive maze procedure is then performed and the patient is weaned from bypass. At this point, the sternum is closed with wires and the skin is reapproximated with staples. The patient tolerated the procedure without difficulty and was taken to the PACU.
