In 2 to 5 out of 100 angioplasty procedures, a coronary artery bypass surgery is required because of complications that develop. This is an infrequent occurrence but you and your family should be prepared for this life-saving intervention, if required.
If your heart cannot provide your body with enough blood during the procedure, an intra-aortic balloon pump may be inserted through a blood vessel in your leg to assist your heart in performing this function. This is a life saving technique, but it is associated with an increased risk for infection, bleeding and blood clots in the leg.
Often your doctor will insert a small pacing wire into the heart to maintain an steady heart rate before, during or after the procedure. This rarely has complications and is often life saving. There is a slightly higher risk of infection and perforation or a tear of the heart with this device but it is commonly used and essential in certain types of heart disease.
