Ascending Aortic Dissection Late After Aortic Valve Replacement / 대한흉부외과학회지

ABSTRACT

Aortic dissection after aortic valve replacement(AVR) is rare, but it is considered a definite disease entity. It's risk factors are a dilated ascending aorta(>or=50 mm) at the time of AVR, hypertension, and thin fragile aortic wall. We report the surgical treatment of a patient who had ascending aortic dissection 7 years after having undergone AVR due to aortic regurgitation associated with a dilated ascending aorta(50mm in outer diameter).
