For heart patients, a new stent for a better life

There’s good reason for 62-year-old Mohammed Sayed’s family to take heart.
On World Heart Day observed on Sunday, Sayed was one rare patient in the city to undergo angioplasty using a relatively new stent.
Doctors at Bombay Hospital used a biodegradable stent to operate on the senior citizen.
“The unique feature of a biodegradable stent is that it dissolves, which helps in the healing process,” said, Dr B.K. Goyal, Bombay Hospital’s head of cardiology, who operated on Sayed.
The other option is to use a drug-eluting stent, in which case, the polymer continues to remain attached for at least two years, causing subsequent medical complications which could prove fatal.
Biodegradable stents have a polymer that dissolves in the body within six months.
This mitigates chances of clots that could form within the stent, as seen in the case of drug-eluting stents.
With the rise in case of blockage in coronary arteries in India, senior city-based cardiologists claimed that bio-degradable stents are indeed a boon.
“These [bio-degradable stents] cost the same as drug-eluting stents,” said Dr Shahid Merchant, senior cardiologist at Lilavati Hospital, Bandra, who has operated on several patients, using such stents.
“The polymer is attached to both types of stents. It helps release medication into the arteries,” said Dr Sudhir Vaishnav, chief interventional cardiologist at Asian Heart Institute, Bandra (E).
“In bio-degradable stents, the polymer dissolves and is absorbed by the body after release of medication. In drug-eluting stents, it stays on and could cause inflammation in the artery as it’s a foreign particle,” said Dr Vaishnav.
“Clinical trials are being conducted on a completely biodegradable stent, where the entire stent dissolves and not the polymer alone,” said Dr Vaishnav.
“It leaves the body on completion of its job.”
