  3. Ever wondered why your heart makes a beating sound? It’s the sound of the opening and closing of your heart valves.

Early intervention often addresses the problem before life-threatening symptoms develop and creates the best chance for survival.

Frequently Asked Questions

What are the myths versus facts about bypass surgery?

  1. Myth: Every heart blockage requires a heart bypass surgery. 
    Fact: Not true! There are also other surgical procedures like angioplasty to clear blockages. In many cases, the symptoms of blockages can even be treated with medicines. A doctor recommends CABG only when the blockage is too severe to be treated with other procedures. 
  2. Myth: A heart bypass surgery is life-threatening. 
    Fact: Like any other surgery, the bypass procedure has some risks, such as infections, bleeding, and arrhythmias. However, the procedure cannot be labelled as life-threatening. With technological advancements, CABG has become one of the safest surgeries. 
  3. Myth: You can undergo CABG only once in a lifetime. 
    Fact: With technological advancements, second bypass surgeries are possible; however, the risk of additional bypass surgeries increases. 
  4. Myth: You cannot do your normal work after bypass surgery. 
    Fact: You need six to eight weeks to recover after the surgery. However, after recovery, you can lead a normal and healthy life as anyone else. Most people return to their normal activities within three to six months. 
  5. Myth: The grafts used in heart bypass surgery can develop blockages. 
    Fact: Traditionally, surgeons used the veins of the legs as grafts for heart bypass surgery, which developed blockage within seven to eight years. However, today, surgeons use the breastbone and forearm arteries as grafts, offering long-term benefits and working for more than 20-25 years.
