Indian Hospitals Provide a Ray of Hope to Heart Patients

Non Surgical Heart Valve Replacement at MyMedOpinionaffiliated hospitals in India

Medical professionals have recently given a new hope of life to all those heart patients in India, who couldn’t undergo open chest surgery due to aging factors or any other complication. India’s first non-operative procedure to replace the damaged aortic heart valve gives a ray of hope to elderly people unfit to undergo surgery.

Doctors at MyMedOpinion affiliated Heart Institute recently performed the path-breaking procedure— per cutaneous trans catheter aortic valve  implantation (TAVI) — on three people above 70 years of age, with damaged aortic heart valve, who were declared inoperable because of their age and underlying medical conditions such as lung or kidney problem, previous heart surgery etc.

“The conventional valve replacement surgery is a major surgery where the heart is exposed by cutting open the chest, but in this procedure, the artificial valve is mounted on a catheter and inserted thorough the femoral artery with a puncture in the groin. It’s more like an angioplasty that is performed in the cath lab under general anesthesia.

The procedure takes about two hours and the person can go home by the fourth day.

Open heart surgery to replace the heart valve remains the first preference of doctors, but for those who cannot be operated on, this technique is a boon. More than 30 percent people with AS can’t undergo open chest surgery due to old age and other complications. For such patients, TAVI will prove to be a fresh lease of life, without which they wouldn’t have life expectancy of more than one year.

At present, the valve is known to last up to 15 years, and the  surgery costs much less than at similar hospitals in USA. After the age of 75 years, 5% population is at the risk of developing a problem in their heart valve, out of which 35% are not suitable for surgery. If not treated, 50% of them will not survive for more than two years.

“I’m happy that I got it done here, otherwise would have had to go to the United States and get it done at an exorbitant price,” said  an 80 year old  patient  who the doctors say would not have survived for more than a year, if the procedure had not been performed.

Drug-Eluting Stents - Angioplasty, Stenting, Interventional Cardilogy Treatments in India

Drug-Eluting Stents

 

Most coronary angioplasty procedures (also called "Percutaneous Coronary Interventions" or PCIs) involve implanting a stent, a small metal scaffold-like device. The stent is mounted on a balloon and guided to a blockage in the coronary artery. The balloon is inflated, compressing the obstructive plaque and opening up the blockage. The balloon is then deflated and withdrawn, but the stent is left behind to support the artery and keep it open as it heals.

Drug-eluting stents are metal stents that have been coated with a pharmacologic agent (drug) that is known to suppress restenosis: the reblocking or closing up of an artery after angioplasty due to excess tissue growth inside or at the edge of the stent.

Restenosis has a number of causes; it is a very complex process and the solution to its prevention is equally complex. Traditional bare-metal stents have restenosis rates of up to 25%; current 2nd and 3rd generation drug-eluting stents have reduced that rate to single digits.

There are three major components to a drug-eluting stent:

• The metal stent structure, also called the stent platform; this is usually made of surgical stainless steel or a cobalt-chromium alloy; these all contain nickel;
• The polymer which coats the metal stent -- this coating contains the drug and delivers (elutes) it to the arterial wall over a period of time;
• The drug itself, which suppresses the formation of excess tissue, sometimes called "scar" tissue.

How are stents placed in an artery?

During an angioplasty, a stent is permanently inserted into the coronary artery.

During angioplasty, the balloon is placed inside the stent and inflated, which opens the stent and pushes it into place against the artery wall to keep the narrowed artery open. Because the stent is like woven mesh, the cells lining the blood vessel grow through and around the stent to help secure it. Your doctor may use a bare metal stent or a drug-eluting stent.

To decide which type of stent to use, your doctor will consider your overall health and your risk of a heart attack. He or she will also consider whether you can and want to take blood-thinning medicines for at least one year.

How do drug-eluting stents work?

All stents have a risk that scar tissue will form and narrow the artery again. This scar tissue can block blood flow. But drug-eluting stents are coated with drugs that prevent scar tissue from growing into the artery. Drug-eluting stents may lower the chance that you will need a second procedure (angioplasty or surgery) to open the artery again.

Living with a stent

You don't have to live differently if you have a stent. But you'll want to take care of your heart by eating healthy, being active, and taking your medicines. There are a few precautions to follow.

Stent identification card. Carry your stent identification card. Your doctor will give you a card for your wallet or purse that you can show to your health professionals so they know that you have a stent.
