A guide on how the treatments of Cardiovascular Diseases have evolved. Flickr

According to an estimate, at present, 4.77 million people die in India due to cardiovascular disease, and this number is increasing rapidly. New treatment techniques have come up to make the treatment much easier for those patients who are unable to undergo open chest surgery due to old age or other issues.

World-class techniques are now available in India for the treatment of severe heart disease like aortic stenosis or dangerous calcified blockages in the coronary artery, says Dr. Ravindra Singh Rao, Specialist, Structural Heart Disease, Jaipur.

The heart valve will change without surgery

About three lakh patients in India do not undergo open chest surgery due to old age or other health-related problems. In such a situation, TAVR technology can prove to be a boon for them, believes the doctor. Till now the patient underwent major open chest surgery at the contraction of the aorta valve. It took a time of several days for the patient to recover after surgery.

But now the Transcatheter Aorta Valve Replacement procedure can replace the patient’s valve without a single cut on the body or any major surgery of the patient. For this, an artificial valve can be reached up via a catheter (simply using a flexible tube inserted through a narrow opening into a body cavity) from the thigh vein to the aorta and the artificial valve can be implanted. In just one to one and a half hours this procedure is completed and on the next day of the procedure, the patient starts moving.

This technique does not have all the risks as in open-heart surgery and the patient can get discharged from the hospital in just 4-5 days prior to the procedure. He may soon return to his normal routine. Whereas after open chest surgery, it takes about six months to one year for the patient to recover completely, says Dr. Ravindra Singh Rao.

When the calcified blockage occurs now, Shock Wave Lithotripsy Angioplasty is an alternative to bypass surgery

Heart blockages occurring in about 90 percent of men and 67 percent of women over the age of 70 are of calcium. Until now, bypass surgery was the only means to correct these blockages, but Shock Wave Lithotripsy Angioplasty Technique has come now as an option to treat patients. It is now possible to insert stents through intervention by doing Angioplasty. This will be helpful for those patients who do not have the capacity to bear bypass surgery. Until now, it was very difficult to perform stenting from interventions in arteries with calcified blockages as there is a 30 to 50 percent risk of re-closure or rupture of arteries after stenting.

Shock wave lithotripsy is a sonographic technique. In this technique, calcium is broken through a sonographic wave and a stent is inserted. This causes no damage to the artery and fine particles of calcium become part of the artery. Angioplasty with this technique takes 45 minutes to an hour and the chances of recurrence of blockage remain about five to seven percent only. (IANS)



When you're pregnant, the immune system is seeing the placenta for the first time in decades.

The US researchers have discovered a class of immune cells that plays a role in miscarriage, which affects about a quarter of pregnancies.

Researchers at the University of California-San Francisco found that the recently discovered subset of cells known as extrathymic Aire-expressing cells in the immune system may prevent the mother's immune system from attacking the placenta and fetus.

The researchers showed that pregnant mice who did not have this subset of cells were twice as likely to miscarry, and in many of these pregnancies fetal growth was severely restricted.

"When you're pregnant, the immune system is seeing the placenta for the first time in decades -- not since the mother made a placenta when she herself was a fetus," said Eva Gillis-Buck, from UCSF.

"Our research suggests that this subset of immune cells is carrying out a sort of 'secondary education' -- sometimes many years after the better-known population of the educator cells have carried out the primary education in the thymus -- teaching T cells not to attack the fetus, the placenta and other tissues involved in pregnancy," she added. The findings are published in the journal Science Immunology.

It's not surprising that over half of those surveyed feel more comfortable using emojis than talking on the phone or in person.

The tiny emojis being shared on billions of devices worldwide can play a major role in digital communication, with most people saying that emoji compels them to feel more empathy towards others, according to an Adobe report.

Adobe's global emoji study found that emoji even helps people overcome language barriers and form connections that would otherwise be difficult to do.

"We were surprised and delighted by the discoveries made in the survey, most notably how enthusiastic respondents were for emoji as a means to express themselves," the company said in a statement.

Emojis sometimes get criticized for being overly saccharine, but this sweetness is key when it comes to diffusing some of the heaviness of online communication.

"Many of the emoji are focused on positive emotions, so it's easy to insert them into our conversations and lighten the mood," the Adobe study said.

Jeff Bezos at the ENCORE awards.

Following the grand Richard Branson show where he carried Andhra Pradesh-born Sirisha Bandla and fellow space travelers on his shoulders after successfully flying to the edge of space, it is time for Amazon Founder Jeff Bezos to applaud Sanjal Gavande, one of the key engineers who designed the New Shephard rocket set to take Bezos and the crew to space on July 20.

Billionaire Bezos is set to fly to the edge of space aboard what is touted as the world's first unpiloted suborbital flight. Born in Kalyan, Maharashtra, Gavande is a systems engineer at Blue Origin who always dreamt of designing aerospace rockets.
