What Is PCI and How Is It Performed?

Understanding Percutaneous Coronary Intervention (PCI)

Percutaneous Coronary Intervention (PCI), commonly known as coronary angioplasty, is a nonsurgical, minimally invasive procedure designed to improve blood flow to the heart. Performed by a cardiologist in a hospital cardiac catheterization laboratory, PCI is used to open coronary arteries narrowed or blocked by atherosclerotic plaque buildup. It helps relieve symptoms of coronary heart disease and limits heart muscle damage during or after a heart attack.

Step-by-Step Procedure Guide

Patients remain awake during PCI but receive relaxing medications and IV drugs to prevent blood clots. The procedure follows a precise workflow:

Vascular Access: The doctor cleans and numbs an access site-typically on the wrist or groin-makes a small puncture, and inserts a catheter into the blood vessel.

Catheter Guidance & Angiography: Guided by live X-rays, the doctor navigates the catheter to the heart and injects an iodine-based contrast dye to highlight blockages.

Opening the Artery: A second catheter with a deflated balloon is advanced over a guidewire to the blockage site. Inflating the balloon flattens the plaque against the artery wall.

Stent Placement: A small mesh tube called a stent is frequently deployed to prop the artery open and maintain healthy blood flow long-term.

Post-Procedure Recovery and Care

After the catheters are removed and the access site is bandaged, recovery involves several key steps:

Monitoring & Rest: Patients recover in a specialized hospital unit for a few hours or overnight. Mild soreness or bruising at the puncture site is common.

Medication Adherence: Patients who receive a stent must strictly take prescribed anticlotting medications-typically for 3 to 12 months-to prevent blood clots from forming inside the stent.

Follow-Up Care: Due to mild sedatives used during the procedure, patients require a ride home, and physicians monitor healing and recovery during scheduled follow-up visits.
