The current success rate for bypass surgery is 95 to 98 percent, meaning that between 2 and 5 percent of all patients have complications, including death.
The development of cardiac surgery and cardiopulmonary bypass techniques has reduced the mortality rates of these surgeries to relatively low ranks. For instance, repairs of congenital heart defects are currently estimated to have 4â6% mortality rates. A major concern with cardiac surgery is the incidence of neurological damage. Stroke occurs in 2â3% of all people undergoing cardiac surgery, and is higher in patients at risk for stroke. A more subtle constellation of neurocognitive deficits attributed to cardiopulmonary bypass is known as postperfusion syndrome, sometimes called pumphead.
