A valve area less than one centimeter squared and a mean gradient greater than 40 millimeters of mercury is generally considered severe. These mechanisms result in the classic symptom triad of dyspnea, angina, and syncope. QT-dispersion, which has been shown to be predictive of cardiac death in other pathologies (long QT syndrome, heart failure, hypertrophic cardiomyopathy, after myocardial infarction) has been shown to correlate with left ventricular mass in AS and a reduction in QT dispersion was also observed after aortic valve replacement (2). Aortic valve stenosis affects 3 percent of persons older than 65 years and leads to greater morbidity and mortality than other cardiac valve diseases. The development of symptoms is a critical point in the natural history of patients with AS. By echocardiography, we are able to determine the heart size and function, were also able to quantitate the degree of stenosis. 2017-01. NE Obstruction may be valvular, subvalvular, or supravalvular. Successful valve replacement restores normal life expectancy. The heart has four valves that keep blood flowing in the correct direction: Each valve has flaps (cusps or leaflets) that open and close once during each heartbeat. The American College of Cardiology/American Heart Association guidelines define severe AS as aortic valve area 1 cm2, mean gradient of 40 mm Hg, and peak velocity of 4 m/s.
