Heart failure due to severe supravalvular aortic stenosis in painless type A aortic dissection.

Severe supravalvular aortic stenosis is a rare complication of aortic dissection. Painless aortic dissection is also relatively rare. We report the case of a 67-year-old man who had New York Heart Association class III heart failure without chest pain and was found to have supravalvular aortic stenosis secondary to chronic type A aortic dissection. The patient underwent ascending aorta and hemiarch replacement with selective antegrade cerebral perfusion under deep hypothermic circulatory arrest. The patient was discharged to home with complete resolution of heart failure and has been carefully followed up for 1 year, during which he has experienced no symptoms.
