At 55, Ratnesh Shah was suffering from frequent chest pain and was advised a coronary angiography — which involves opening up blocked vessels. Unfortunately, both his femoral (groin) arteries were closed because of a vascular disease. Also Read - New test can eliminate need for surgery to diagnose ovarian cancer

His radial (wrist) arteries were also calcified and had lesser capacity to bear with an incision, with tests showing that nothing wider than 1.7 mm could enter the arteries. Also Read - As Google Doodle celebrates 50 years of LGBTQ Pride, know all about gender dysphoria

Thus, it was difficult for him to undergo angiography, in which a tube (called sheath) and another smaller tube (catheter), together measuring at least 2.8 mm, are inserted in the arteries. Also Read - Kidney cancer: All you need to know about the treatment options

It was then that Shah came to know about a new technique called “sheathless” angiography, which is also less painful.

“Not everyone is in a position to undergo angiography, which can be painful owing to the size of insertion required in the arteries,” Narayan Gadkar, a doctor from Jupiter Hospital in Thane, near Mumbai, who started performing the new procedure in 2010, told IANS.

In sheathless angiography, the catheter is directly introduced in the arteries.

Gadkar, among the pioneers of the technique, has done nearly 400 sheathless angiography tests so far, but the procedure is still not well known.

“Angiography is a medical imaging technique used to visualise the inside or lumen of blood vessels and organs of the body with a particular interest in the arteries, veins and the heart chambers. A pipe-like object known as sheath is inserted in the arteries, through which the catheter, 1.8 millimetres ( mm) in diameter, is inserted,” he explains.

“It is a painful experience, specially for Indian patients, as they have narrow arteries,” he added.

“Generally, after puncturing the artery with a wire, we introduce a sheath, through which we put a catheter, which is painful. But in the method we use, we put in a catheter without the sheath, which ensures one millimetre of less invasion,” said Gadkar.

“Traditionally, it was done through groin arteries. The puncture made on the wrist is much smaller than usual,” he said.

The puncture on the wrist is also easier than the groin procedure, which involves complications like immobilisation, Gadkar added.

According to figures released by the World Health Organisation (WHO), 60 percent of the world’s cardio-vascular patients are expected to be in India by 2016. The country already has more than 100 million heart patients.

With a high number of young adults being affected by heart problems, angiography is one of the most widely used methods to diagnose heart problems and blockages at an initial stage.

“People are usually afraid of angiography and they keep on avoiding it. This results in heart attacks,” the doctor adds.
