Question: I am 44 years old, two years ago I underwent surgery and had four bypasses implanted. I would like to know if they will last forever or will have to be changed over time. José (Granada).
Answer: The coronary bypass technique is used in patients with obstructions of the coronary arteries, to improve the blood "supply" to the myocardium. There are two types of coronary bypass (or grafts): arterial (from the mammary or radial artery) and venous (saphenous vein grafts, which is a vein in the leg). We assume that you, having four bypasses, will have both types, both arterial and venous.
