City docs replace heart valve via electrosurgery in woman
Jaipur: For the first time in India, doctors at Jaipur's Rajasthan Hospital (RHL) have successfully performed the country's first electrosurgical valve-in-valve mitral procedure, officials said Wednesday. The patient, a 74-year-old woman from Jammu and Kashmir's Srinagar, had earlier undergone open-heart surgery for dual valve replacement and was facing heart failure again due to a malfunctioning mitral valve. The mitral valve is one of four valves in the heart and is located between the heart's upper left (left atrium) and lower left chamber (left ventricle). It directs blood from left atrium to left ventricle. According to officials, the doctors in Srinagar and Delhi ruled out conventional surgery due to her age and fragile health condition. Subsequently, the family approached the private hospital in Jaipur for treatment, where the surgery was performed. Dr Ravindra Singh Rao, chairman of RHL Heart Centre, and his team operated on her using an advanced electrosurgical technique. "Using a minimally invasive catheter-based approach, the team employed precision electrosurgical tools, including a fine electrified wire, to precisely open part of the malfunctioning mitral valve and implant a new one, all without opening the chest," Dr Rao said in a release. This procedure is informally referred to as the Batman procedure, as a catheter with a deflated balloon is inserted into the patient's blood vessel to repair or replace the mitral valve. The shape of the balloon resembles Batman's cape, hence the surgery is called the Batman procedure. PTI

28 ventilators lie idle in Hazaribag hosp since 2020, superintendent assures action
1 2 Hazaribag: Since the height of the Covid-19 in 2020, 28 life-saving ventilators have been gathering dust in the ICU of Sheikh Bhikhari Medical College Hospital, unused and forgotten, Hazaribag's Sadar MLA, Pradip Prasad, has raised alarm over this critical healthcare oversight at the health unit. These machines, purchased to combat the pandemic, have yet to see the light of day, leaving patients in dire need to be referred to Ranchi for critical care. Prasad has called this not just negligence but a dangerous gamble with the lives of those seeking medical help. He has demanded swift action from the state health department to rectify this oversight immediately. Speaking to TOI, Prasad said, "These ventilators have been sitting idle for years. No steps were taken to operationalise them, nor was there any effort to appoint trained operators. This is a grave disservice to our community." Prasad also highlighted shone a light on other pressing issues plaguing the hospital, including cleanliness, a shortage of medicines, poorly maintained equipment, and a lack of staff. He stressed the urgent need for solutions. In response to Prasad's concerns, his team met with the hospital superintendent, Dr Anukaran Purti, to delve into these issues. They discussed the hospital's current system, resource status, and the challenges faced on the ground. Purti, acknowledging the gravity of the situation, promised swift action. "I will address these issues, including the ventilators, to ensure they are operational soon," he said.
