Are this many complications common after open heart surgery? my dad, 69 years old--overweight but no other health problems other than heart. 11 days ago had triple bypass, aortic valve replacement, and block for afib. two hours after surgery needed anot

I : I am so sorry that your dad and your family are having to go through this. As you know, that is an extremely major surgery. Triple bypass with aortic valve replacement and procedure for atrial fibrillation is extremely extensive surgery. Factors that can affect the surgery and outcome include the condition of the patient prior to surgery, age, kidney function prior to surgery, and the condition of the heart prior to surgery. Keep an open line of communication with the doctor and nursing staff so that your family's questions can be answered to your satisfaction. I wish the best for your father.

Dr Guyton agreed

Depends: Coronary blockage- bypass and generally improved prognosis are the general results risks of procedures are being reduced all the time. But patients are older and bring more intrinsic personal risks. Risks are dying, bleeding, infection, stroke, recurrence. Over all about 2%.
