Coronary artery bypass surgery, also known as Coronary Artery Bypass Graft (CABG), is an open-heart operation that improves blood flow to the heart muscle. It is used for coronary artery disease where blockages are extensive or unsuitable for angioplasty. In some patients, the surgery may be carried out with a small window that avoid the need to open up the breastbone (minimally invasive cardiac surgery).
01Why It’s Done
Dr Lee may recommend this for patients with:
Multiple or complex blockages of the coronary arteries
Disease not suitable for angioplasty
Significant blockage of the distal left main coronary artery involving bifurcation, especially if heavily calcified.
02How It Works
A healthy blood vessel is taken from the leg, forearm or chest.
It is grafted above and below the blocked section of the coronary artery.
Blood flow is rerouted, “bypassed”, around the narrowing.
Several bypasses may be created, giving rise to terms such as “double” or “triple” bypass.
03Duration, Recovery & What To Expect
Coronary bypass is a major operation with a structured recovery and cardiac rehabilitation programme. Dr Lee will refer you to the right surgeon for your condition and will follow up closely throughout the whole process.
