aortic insufficiency
Also written as: AI — aortic insufficiency
Backward flow of blood from the aorta into the left ventricle due to incompetent aortic valve.
Full Definition
Aortic insufficiency, also known as aortic regurgitation, is a valvular heart disease characterized by incomplete closure of the aortic valve, allowing blood to flow backward from the aorta into the left ventricle during diastole. In cardiac anesthesia, this condition significantly impacts anesthetic management and surgical planning. Severe aortic insufficiency can compromise cardioplegia delivery, affect preload management, and influence the choice of monitoring techniques. The condition may be acute or chronic, with different hemodynamic implications for perioperative care.
Usage
Usage note: Often abbreviated as AI; use aortic regurgitation interchangeably.
