A team led by the head of the department at Rajindra Hospital, Dr Manjeet Singh, Dr Anil Suri and Vijay Kumar Bodna, both associate professors have examined the heart samples of Fiza which was in a "highly decomposed" state.
"We have received the heart in a very decomposed state," Dr Bal told reporters here today.
He said that the decomposition of the victim's body for 3-4 days has led to Autolysis of cells.
Elaborating Autolysis, Dr Bal said that Autolytic cell destruction is uncommon in living adult organisms and usually occurs in injured cells or dying tissue.
The doctors have re-examined the heart and arrived at the conclusion that the cause of death is due to Autolysis, he said, adding that it is not clear from the samples why she had a heart failure.
Anuradha Bali (39), the estranged wife of former Haryana Deputy Chief Minister Chandermohan, was found dead at her residence in Mohali near here on August 6.
