Angioplasty

Dr Mathew Samuel Kalarickal, a renowned cardiologist, passed away on April 18, 2025. He was celebrated as the “Father of Angioplasty in India.” His contributions have shaped cardiac care in the country. Angioplasty is a vital medical procedure that addresses blocked arteries supplying blood to the heart.

What Is Angioplasty?

Angioplasty is a minimally invasive technique designed to open blocked arteries. The term combines “angio,” referring to blood vessels, and “plasty,” meaning treatment. Blockages in the coronary arteries can lead to reduced blood supply, causing conditions like angina. Atherosclerosis, characterised by plaque buildup, often leads to these blockages. Angioplasty can be performed during a heart attack or as a preventive measure.

How Angioplasty Differs From Other Procedures

Angioplasty is less invasive than traditional open-heart surgery. It involves a small incision in the groin or arm to insert a catheter. This catheter widens the blocked artery, restoring blood flow. In contrast, bypass surgery requires a larger chest incision and a longer recovery time. Patients often leave the hospital within 24 hours of an angioplasty.

Types of Angioplasties

There are several methods of performing angioplasty: 1. Balloon Angioplasty – A small balloon is inflated to push plaque against the artery walls. 2. Stent Placement – An expandable mesh tube, or stent, is inserted to keep the artery open. Innovations include bioresorbable stents that dissolve over time, allowing natural artery function. 3. Laser Angioplasty – Excimer Laser Coronary Angioplasty (ELCA) uses a laser to remove plaque in severe cases where traditional methods may not suffice.

Dr Mathew Samuel Kalarickal’s Impact

Dr Kalarickal studied at the Government Medical College in Kottayam and pursued further training in the US under Dr Andreas Gruentzig. After returning to India in 1985, he introduced angioplasty to a country where it was largely unknown. He founded the India Live cardiology conference and the National Angioplasty Registry of India, promoting collaboration among interventional cardiologists and ensuring adherence to international standards.

Current Relevance of Angioplasty

Angioplasty remains a critical procedure in cardiac care. It has evolved with advancements in technology and techniques. The introduction of bioresorbable stents exemplifies ongoing innovation in the field. As heart disease continues to be a leading cause of mortality, angioplasty plays an essential role in saving lives and improving patient outcomes.
