A triple bypass heart surgery occurs when a surgeon reroutes blood around blockage in three arteries, according to the Society for Cardiovascular Angiography and Interventions. Coronary bypass surgery is a treatment for heart attacks or chest pain caused by blockages in arteries that send blood to the heart. Depending on the number of arteries that need the intervention, an individual may have a double, triple or quadruple bypass surgery.
During bypass surgery, a surgeon connects a blood vessel from another body part into the heart artery, so blood goes around the blockage in the artery, explains the Society for Cardiovascular Angiography and Interventions. This surgery can provide relief from angina discomfort and difficulty breathing due to cardiovascular disease. Some complications of this procedure are heart rhythm problems, blood clots and kidney failure. Other severe side effects include death, reactions to anesthesia and infection at the incision site. Patients at higher risk for complications are those over the age of 70, females and those who undergo emergency surgery.
Complications from triple bypass surgery are rare, and the risk of death after surgery is present in only 1 to 2 percent, notes the Society for Cardiovascular Angiography and Interventions. More than 95 percent of people who have bypass surgery do not experience severe complications.
