Rahman explained: “The pump was able to deliver an additional 3.5 litres of blood a minute – which was in addition to what John’s heart was already able to pump, bringing it to near-normal levels during the procedure.

“Most patients undergoing heart procedures, such as coronary angioplasty or stents, will not need one of these devices.

“But for patients like John, undergoing high-risk procedures, research shows these pumps increase survival by more than 70% up to six months after surgery.”

The 15 pumps gifted by Sheffield Hospitals Charity are expected to benefit about one patient a month.

Those are expected to include patients referred from hospitals in Doncaster, Barnsley and Chesterfield who are experiencing cardiogenic shock, or those who are in acute cardiac distress, such as patients awaiting a heart transplant, those with multiple illnesses and those undergoing high-risk cardiac procedures.
