Quizplus · Accepted Answer

The surgical procedure described is called minimally invasive direct coronary artery bypass (MIDCAB). It involves making a small incision over the blocked coronary artery while the heart is still beating and using an artery from the chest wall as a bypass. PTCA (percutaneous transluminal coronary angioplasty) involves using a balloon catheter to open up a blocked coronary artery from the inside, while CABG (coronary artery bypass graft) involves creating a bypass using a vein or artery from elsewhere in the body. TMR (transmyocardial revascularization) is a procedure in which channels are created in the heart muscle to improve blood flow.
