Projected aortic valve area
WebProjected aortic valve area at normal transvalvular flow rate (250 mL/min) - EOA proj - is an echocardiographic parameter that was developed in order to overcome this limitation. It consists of the effective orifice aortic area that would have occurred at a standardized flow rate of 250 mL/min, ... WebWhere is the aortic valve located? The aortic valve is between your left ventricle and aorta. Looking at your heart straight on, your aortic valve is near the middle of your heart. Your pulmonary valve is to the right and in front of your aortic valve.
