Kochi: In news that can bring in cheer for patients suffering from severe heart diseases in India, a doctor from India has become the first surgeon in the country to undergo advanced training in `artificial heart` technology.
The artifical heart, which is implanted inside the chest just below the patient`s damaged heart, works on the principle of `linear axial flow` and weighs 250 to 300 grams. It has a rotar that would rotate upto 10,000 times per minute and pump blood upto 10 litres a minute, he said. Adding that the artificial heart works on recharged batteries, he said one battery would last up to 15 hours after which another battery can be attached. Six batteries would be given to the patient which can be recharged. The patient would need two batteries a day, he said. Another battery with capacity for half an hour emergency back up would be connected to the machine all the time and would get recharged from the already charged battery, he said. The patient would be given specially made jackets to place the batteries in pouches. A computerised module would be on the patient`s waist from which a cable would go to the artificial heart. One end of the artifical heart would be connected to the damaged heart and the other end to the major artery of the body `aorta`, Dr Moosa said, adding depending on the patient`s requirement, the heart would pump the required blood. Dr Moosa said he was making efforts to bring the technology to India. Efforts would be made to develop artificial hearts in India at much cheaper rates of about Rs 5 lakh, he said. Dr Moosa said that with the new technology, the life spans of patients with "completely damaged hearts" can be increased to 10 years or more from 6 months to one-two years.PTI
