In a lighter vein, we refer to the interventional cardiologists as the ‘cardiac plumbers’ and ‘electricians’. By the same logic, Cardiac Surgeons are the ‘carpenters’ because they repair diseased hearts.
The popular term ‘Bypass Operation’ is short for Coronary Artery Bypass Graft (CABG) surgery. This major operation is undertaken as a treatment in selected cases of coronary artery disease (CAD). This operation improves the blood flow to the heart, eliminates the chest pain and discomfort, reduces fatigue and need for medicines, increases the capacity for physical activity and restores a sense of well being. Without CABG or Coronary Angioplasty, coronary arterial blockages can be debilitating or even fatal.
Luckily, the whole length of an artery is never blocked, only a part of it is. The part of the artery beyond the block is often open. When the blockages are complicated and involve many coronary arteries, the cardiologist will recommend a Bypass Operation. This operation will establish new pathways to carry blood beyond the blockages.
