Angioplasty surgery procedure.
>> Friday, February 28, 2020
.
The doctor threads a thin tiny balloon catheter tube through a blood vessel in the arm or groin up to the involved site in the artery to help widen it and improve blood flow to heart.
. .
A small amount of contrast liquid is put into blood vessel through the catheter. It’s photographed with an X-ray as it moves through heart's chambers, valves, and major vessels.
.
From those pictures, doctors can tell if coronary arteries are narrowed and in some cases whether the heart valves are working correctly.
.
If the doctor decides to perform angioplasty he will move the catheter into the artery that’s blocked. He’ll then do one of the procedures described below.
.
There are several your doctor will choose from. They include:
.
Balloon: A catheter with a small balloon tip is guided to the narrowing in artery. Once in place, the balloon is inflated to push the plaque and stretch the artery open to boost blood flow to the heart.
.
Stent: This is a small tube that acts as a scaffold to support the inside of coronary artery.
.
A balloon catheter, placed over a guide wire, puts the stent into narrowed coronary artery. Once in place, the balloon is inflated, and the stent expands to the size of the artery and holds it open.
.
The balloon is then deflated and removed while the stent stays in place. Over several weeks, artery heals around the stent.
.
The whole thing lasts from 1 to 3 hours, but the preparation and recovery can add much more time. You may stay in the hospital overnight for observation.
