Assessment of Aortic Valve Stenosis Severity

Assessment of aortic valve stenosis severity using intelligent phonocardiography.

Assessment of aortic valve stenosis severity: A new index based on the energy loss concept.

BACKGROUND Fluid energy loss across stenotic aortic valves is influenced by factors other than the valve effective orifice area (EOA). We propose a new index that will provide a more accurate estimate of this energy loss. METHODS AND RESULTS An experimental model was designed to measure EOA and energy loss in 2 fixed stenoses and 7 bioprosthetic valves for different flow rates and 2 different...

Aortic Valve Stenosis

DISCRETE, non-mycotic aortic aneurysm associated with aortic stenosis is a rare entity. Only 11'-cases have been reported in the literature, 10 associated with valvtular lesions and one with subvalvular stenosis (table 1). That this association is not mere]y a coincidence has been demonstrated in several recent papers,-i and the pathogenesis of these aneurysms has been investigated.10-15 It is ...
