aortotomy
Pronunciation: /ā-ˌȯr-ˈtä-tə-mē/
Surgical incision into the wall of the aorta to access the aortic valve or aortic root.
Full Definition
Aortotomy is a surgical incision made into the wall of the aorta, typically performed during aortic valve surgery or aortic root procedures. The most common approach is a transverse aortotomy made in the ascending aorta above the coronary ostia, providing excellent exposure of the aortic valve. The incision must be carefully planned to avoid injury to the coronary arteries and to ensure adequate closure without distortion of the aortic root geometry. Following completion of the intra-aortic procedure, the aortotomy is closed with a running polypropylene suture, often reinforced with pledgets or felt strips. Proper technique is essential to prevent bleeding and maintain aortic root integrity.
