An apicoaortic conduit, also called aortic valve bypass, is a cardiothoracic surgical procedure that relieves obstruction of blood flow from the heart left ventricle caused by a narrowed or diseased aortic valve. A bioprosthetic valve is implanted to create a second pathway so blood can bypass the native valve and exit the heart, reducing the pressure gradient responsible for the patient symptoms.

Which patients is an apicoaortic conduit considered for?
It is described as an option for selected patients at extreme risk for standard aortic valve replacement.
A case report in the medical literature describes the conduit as an option for selected patients who are at extreme risk for standard surgical aortic valve replacement owing to porcelain aorta and high-risk resternotomies. This fits the purpose of the procedure, which gives blood a second pathway out of the heart so that it bypasses the narrowed native valve instead of replacing it.

History section
The concept of an apicoaortic conduit to bypass valvular aortic stenosis (AS) was conceived by Carrel in 1910, and performed experimentally by Sarnoff and colleagues on dogs in 1955.

Apicoaortic Conduit (AAC), also known as Aortic Valve Bypass (AVB), is a cardiothoracic surgical procedure that alleviates symptoms caused by blood flow obstruction from the left ventricle of the heart.
Treats: Aortic Stenosis, Outcomes
AVB effectively relieves the LVOTO caused by aortic stenosis.
