My father had a coronary angiogram, the doctor said he had many blocked vessels, couldn't put a stent, he could only have a bypass surgery. So the doctor asked me how the coronary artery bypass surgery procedure is performed? When performing bypass surgery, a blocked branch must be bridged, or only one bridge should be taken for all blocked blood vessels.

Coronary stenting is a cardiovascular intervention that improves myocardial infarction, but not every stent is a cure for coronary artery disease. How long a coronary stent lasts depends on many factors.
