Chennai hospital introduces laser angioplasty for blocked arteries

A private hospital in Chennai has introduced laser angioplasty, a new minimally invasive procedure to treat blocked arteries. The technology uses laser energy to vaporize plaque, offering an alternative to traditional balloon angioplasty and stenting.

The hospital announced the launch on Friday. Officials said the procedure can treat blockages that are hard to reach or manage with conventional methods.

How laser angioplasty works

Laser angioplasty involves threading a thin catheter through the artery to the blockage site. A laser tip at the end of the catheter delivers controlled pulses of light energy. This vaporises the plaque, restoring blood flow.

Doctors at the hospital said the technique is particularly useful for patients with long, calcified blockages or those who have failed previous stenting. It can also treat blockages in smaller blood vessels.

Unlike balloon angioplasty, which pushes plaque against the artery wall, laser angioplasty removes the plaque entirely. This lowers the risk of the artery narrowing again, a condition called restenosis.

Targeted treatment for complex cases

The hospital plans to use laser angioplasty primarily for peripheral artery disease (PAD) affecting the legs. PAD can cause pain, ulcers, and even gangrene if left untreated. The technology may also be used for coronary artery blockages in select patients.

Dr. R. Suresh, a senior cardiologist at the hospital, said the procedure is “a game changer for patients who have no other options.” He added that the laser can cut through hard, calcified plaque that balloons cannot open.

The hospital has invested in the laser system, which costs several crore rupees. Officials said the procedure will be available at a premium over standard angioplasty but declined to specify exact pricing.

Recovery and outcomes

Patients who undergo laser angioplasty typically stay in the hospital for a day or two. The procedure is done under local anaesthesia and takes about an hour.

Doctors report high success rates with minimal complications. The laser tip is designed to only target plaque, reducing damage to the artery wall. Bleeding and infection risks are low.

The hospital said it has already performed a few successful procedures. Patient feedback has been positive, with many reporting immediate relief from pain and improved mobility.

What this means for patients

Laser angioplasty is not new globally, but its availability in Chennai expands treatment options for patients in southern India. Until now, patients with complex blockages often had to travel to Delhi, Mumbai, or abroad.

The hospital aims to train more interventional cardiologists in the technique. Plans are underway to start a dedicated laser angioplasty clinic within the next few months.

The technology is not suitable for every patient. Doctors will evaluate each case to determine if laser angioplasty is the best option.

As the hospital rolls out the service, the medical community in Chennai will watch closely for long-term outcomes. If successful, more hospitals in the city may adopt the technology, giving patients more choices for treating stubborn blockages.
