Rashtriya Janata Dal chief Lalu Prasad Yadav today underwent an over six-hour-long cardiac surgery at a hospital here today.
According to the hospital statement, during the surgery, which lasted for six hours and 15 minutes, he underwent AVR- aortic valve replacement, aortic repair and repair of a 3 mm hole in the heart.
The former Bihar chief minister has been diagnosed with 'aortic stenosis', and was admitted to the Asian Heart Institute here on Monday.
Institute head Dr Ramakanta Panda, who had operated on former Prime Minister Manmohan Singh five years ago, said the decision to perform the surgery followed a series of medical tests and evaluation on the 66-year-old leader.
Meanwhile, RJD leaders and legislators and well-wishers conducted 'hawan' and special prayers at party headquarters in Patna, for his speedy recovery.
