A novel multi-planed mechanical aortic valve for increasing the effective orifice area.
BACKGROUND
Today, there is still confusion about mismatch of the orifice area of the mechanical valve and body surface area of the patient in aortic valve surgery. Creating a larger effective orifice area is the aim with this new valve design.


METHODS
This valve is multi-planed, one housing is seated at the aortic annulus for the coronary orifices to receive blood in diastole, the other housing or housings are seated to the ascending aorta obliquely to increase the orifice area of the valve. The ascending aorta can be enlarged if necessary.


RESULTS
Valves with orifice areas larger than 6 cm(2) can be achieved with multi-planed aortic valves.


CONCLUSIONS
The use of this valve depends on the fact that the aorta is a living tissue and can grow over time to normal values.
