If angioplasty is not possible the blocked vessels in the heart can sometimes be replaced by taking healthy vessels (usually from the leg). The procedure is carried out by a cardiac surgeon. There are three cardiac surgeons available at Spire Hull and East Riding Hospital to perform coronary artery bypass graft operations. Patients have at least 1 night in the intensive care suite. With daily physiotherapy patients are usually ready to go home after 8 days.
