aortotomy
Pronunciation: ay-or-TOT-oh-mee
Surgical incision into the aorta to provide access for valve surgery or repair of aortic pathology.
Full Definition
Aortotomy is a surgical technique involving the creation of an incision in the wall of the aorta to gain access to the aortic valve or to repair aortic pathology. The incision is typically made in the ascending aorta above the coronary ostia and may be oriented transversely, obliquely, or longitudinally depending on the procedure requirements. This approach is essential for aortic valve replacement, valve repair, or removal of aortic root pathology. The aortotomy must be carefully closed with appropriate suturing techniques to prevent bleeding and ensure hemostasis.
Usage
Usage note: Specify orientation (transverse, oblique, longitudinal) and location relative to coronary ostia.
