The procedure described is transmyocardial revascularization (TMR), which involves using a laser to make small channels in the heart muscle. These channels are thought to stimulate the growth of new blood vessels and improve blood flow to the heart. PTCA (percutaneous transluminal coronary angioplasty), MIDCAB (minimally invasive direct coronary artery bypass), and CABG (coronary artery bypass grafting) are all different procedures for treating coronary artery disease, but they do not involve the use of a laser to make holes in the heart tissue.
