short by Saloni Tandon / on 20 Feb 2018,Tuesday
A 56-year-old Indian man, diagnosed with end-stage heart disease, was left with two beating hearts following a 'Piggyback Heart Transplant' at Hyderabad's Apollo Hospital. Doctors decided on keeping both hearts due to size difference, with the donor heart being normal fist-sized, while the patient's heart was the size of a small football. Only about 150 such procedures have been reported.
