Transthoracic echocardiography revealed an aortic valve opening area of approximately 0.9 cm², a peak systolic flow rate of 4.5 m/s, a differential pressure gradient of 82 mmHg, a left ventricular ...
In patients greater than age 65, more than 90% of aortic stenosis involves trileaflet valves which have developed heavy calcification. [5] In these instances the calcium deposits are thought to ...
The exclusion criteria included myocardial infarction within 6 months, regional wall motion abnormalities on echocardiography, prior cardiac surgery, more than mild mitral valve disease or aortic ...
had stenosis with a minimal aortic valve gradient of 16 mm Hg. In these patients, cardiac and vascular risk factors were compared with 568 control patients using multiple logistic regression analysis.
A small percentage of malfunctioning congenitally abnormal aortic valves are unicuspid or unicommissural,5 but as most reports do not distinguish this from bicuspid aortic valve the abbreviation ...
The latest development should bolster Edwards’ Transcatheter Aortic Valve Replacement ... lower echo-derived gradients across all valve sizes and no paravalvular leak in 84.4% of cases.
