The revolutionary HeartMate-II LVAD (Left Ventricular Assist Device), which made its successful debut in London a few months ago, has featured in another successful heart transplant operation in a Chennai hospital. “It is not just a technological breakthrough but has also given hope for many heart patients,” said Dr K R Balakrishnan, Cardiothoracic surgeon and Director of Cardiac Sciences at the leading Chennai hospital. “HeartMate-II LVAD is a small, battery-driven rotor pump device, the latest version of which is made of “sintered microsphere titanium”, said Dr Suresh Rao, a member of the team that performed the operation.
The new pump is a miniature, but more sophisticated version of the initial version of Heartmate. Shaw explained, “The refined features of the Heartmate 2 include computer technology which will allow Barry to read out power consumption and blood flow if he is feeling unwell to alert doctors. There is also a built-in back up battery in case he accidentally disconnects the power.” The pump is charged by 2 portable batteries which are carried in the patient’s shoulder bag. This landmark device, also known as Left Ventricular Assist Device (LVAD), weighs around 12 ounces and costs £100,000 (INR 55 Lakh).
