NEW DELHI: For heart patients, who require valve replacement but are unfit for an open heart surgery, there's hope on the horizon.
Usually, a patient with a defective valve has to undergo CHECK VALVES
an open heart surgery in which the thoracic cavity is cut open to implant a new valve. But patients above 65 years of age and those with poor health condition are considered unfit for the complex surgery. However, they can now bank on a new method widely practised in Europe Percutaneous Aortic Valve Replacement (PAVR) technique to get their diseased valves replaced without having to go under the knife. Using this method, doctors transport a synthetic valve to the heart through a small hole made in the groin area. And now for the first time in India, cardiologists at the Medanta Medicity Hospital in Gurgaon will perform this procedure on patients next week.
"Six patients have been screened already. We have sent letters to more patients, who had to be turned away earlier as they were unfit for open heart surgery. The procedure will be conducted next week by a team of doctors from the hospital and experts from Europe,'' said Dr Praveen Chandra, chairman of the division of interventional cardiology at Medanta Heart Institute, adding that Medanta is the first hospital inGATE VALVES
the country to perform this procedure.
In this technique, Chandra said, a small puncture is done in the groin vessels with or without anaesthesia depending on the condition of the patient. "The prosthetic valve is passed through lower limb blood vessels to the heart and is positioned correctly over diseased valve under X-ray guidance. The entire process takes up to one hour unlike the open heart surgery which requires at least 4-5 hours. Unlike surgery, it doesn'tSAFETY VALVES
require cutting open of chest wall and heart which requires three months for complete recovery,'' Chandra said, adding that patient whose valve has been replaced through PAVI is ready to go home in 4 days. At Medanta, the cardiologists said, they will use tissue heart valve which is made from animal tissues.
"The new surgery will be a boon for old patients suffering from aortic valve stenosis, high-risk patients like those suffering from chronic obstructive pulmonary disease (COPD) and previous bypass surgery patients among others. The only concern is that valve implantation through this process is going toMUD VALVES
to be costlier. It will cost a patient about Rs 12 lakh. But, once the technique is popular, I am sure the rates would come down,'' said Dr Naresh Trehan, chairman and managing director of Medanta Medicity. He said that the technique has proved to be a success in several European countries, including Italy, the United Kingdom, Belgium and France.
Doctors say that valve needs to be replaced if it gets narrowed due to calciumMULTI-FUNCTIONAL WATER PUMP CONTROL VALVE
deposition or degeneration, which may lead to restricted blood supply from the heart to other parts of the body. In some patients, the valve degenerates due to congenital defects.

新德里消息：对于心脏病患者瓣膜置换谁需要一个开放，但不适合心脏手术，有在地平线上的希望。
通常，一个有缺陷的瓣膜病人在接受心脏手术蝶阀
在一个开放而被切开的胸腔植入一个新的阀门。但是，上述患者65岁，健康状况欠佳的那些被认为是不适宜的复杂手术。不过，他们现在可以在欧洲银行在广泛经皮主动脉瓣置换术（PAVR）技术得到实行，而不必去下刀的病变瓣膜替换的新方法。使用这种方法，医生运输一种合成的心脏瓣膜通过在腹股沟领域取得的一个小洞。现在在印度的第一次，在Medanta Medicity呼吸阀
古尔冈医院心脏病患者将执行此程序下周。
“六病人已筛选了。我们已致函给更多的患者，谁不得不转过身去，因为他们是早期心内疏水阀
直视手术不适合。该过程将通过一个从医院的医生和专家小组下周从欧洲，''体育大臣菩钱德拉博士说，对心脏研究所在Medanta介入心脏科董事长，并补充说Medanta是全国第一医院执行此过程。
这种技术，钱德拉说，一个小穿刺做是腹股沟船只或不麻醉根据患者的病情。 “这是隔膜阀
通过人工瓣膜下肢血管，心脏和定位是根据以上X光阀的正确指导患病。整个过程需要长达一小时内直视手术不同的是它至少需要4-5小时。不同于手术，它不要求削减胸壁及心脏，需要3个月完全康复开放，''钱德拉补充说，病人的瓣膜替换已通过PAVI是准备在4天回家Medanta。的心脏病专家说，他们将利用组织心脏瓣膜是从动物组织的。
“新的手术将是从主动脉瓣膜狭窄症老年患者福音，像那些从慢性阻塞性肺疾病（COPD）和以前旋塞阀
的旁路手术病人的痛苦等高危病人。唯一关心的是，通过这一进程阀植入术将是昂贵的。它会使病人约12 500,000卢比。但是，一旦这种技术很受欢迎，我相信利率将下降，''纳雷什Trehan博士说，董事长和总经理Medanta Medicity主任。赫说，该技术针型阀
已被证明是一个在几个欧洲国家，包括意大利，英国，比利时和法国的成功。
医生说，阀门需要更换，如果它得到缩小因钙沉积或退化，这可能导致限制从心脏血液供应到柱塞阀
身体的其他部位。在一些病人，因先天性瓣膜退化的缺陷。
