Jaipur, May 21 -- Doctors at Sawai Man Singh Hospital have carried out three rare and highly complex heart surgeries on a 27-year-old patient in a single eight-hour operation, giving him a new lease of life. The operation, led by senior cardiac surgeon Dr Anil Sharma, is being described by hospital staff as among the rarest procedures worldwide, with clinicians saying fewer than 10 such cases have been reported globally, read a statement released by the hospital. "The patient suffered from a congenital narrowing of the aorta, known as coarctation of the aorta (COA), together with a severely damaged heart valve and a dangerous aneurysm in the aortic arch. Doctors estimated he faced more than an 80% risk of death within a year without intervention," the statement read. Surgeons performed three major cardiac procedures in one sitting. First, they carried out the Bentall procedure, replacing the damaged valve and ascending aorta with an artificial graft while reconnecting the coronary arteries. Second, they replaced the aortic arch, addressing a rare bovine-arch abnormality. For this stage, the team cooled the patient's body temperature to 20degC and halted systemic circulation for 32 minutes; cerebral perfusion was maintained separately during this critical phase to prevent brain injury. Third, surgeons repaired the narrowed section of the aorta by excising the constricted segment and attaching an arch graft. Doctors said combining all three procedures made the case exceptionally rare and risky. "Treatment was provided free under the Rajasthan government's Bhamashah health scheme," the statement read. The operation was led by Dr Anil Sharma, head of the cardiothoracic and vascular surgery department, and involved Dr Sunil Dixit, Dr Mohit Sharma, Dr Saurabh Mittal, Dr Vakta Ram Chaudhary, Dr Gaurav, Dr Preetanshi, Dr Rakesh, Dr Kulraj and Dr Suraj. The cardiac anaesthesia team comprised Dr Reemi Meena, Dr Anjum and Dr Arun. Perfusionists Pranjali, Pulkit and Aarti, and nursing in-charge Sudha and her team, also played key roles in the operation....
