What invasive medical procedures treat heart disease?
When angina symptoms worsen despite medications, you may need an invasive procedure in the cardiac catheterization lab to clear the blocked artery. These procedures are performed by a cardiologist, not a cardiac surgeon, and have fewer complications.
Coronary angioplasty (PTCA): This procedure is similar to coronary angiography (cardiac catheterization or a dye study to visualize the inside of coronary arteries) but is therapeutic as well as diagnostic.
Stent: A stent is a small, sieved, coil-like metallic tube or scaffold mounted over a balloon.
What about surgery for heart disease?
Surgery in coronary heart disease is reserved for people whose disease is either severe or is not improved or stabilized by medication and other less invasive therapies.
Coronary artery bypass grafting (CABG): This is the standard operation for blockages of coronary arteries.
Off-pump bypass surgery: Sometimes surgeons can perform open heart surgery without using a bypass pump and while the heart is beating. The procedure causes fewer side effects than the standard procedure, but it is not feasible in all situations.
Minimally invasive coronary bypass (MINI-CABS): If just your front or right coronary arteries need bypass, a surgeon may replace the blocked artery with an artery from the
