Two-dimensional Echocardiography in Semilunar Valve Disease
M-mode echocardiography has been widely employed in the past in attempts to diagnose valvular aortic stenosis [1—4]. It has also been used to examine the pulmonic valve, and has been very helpful in the detection of pulmonary valvular stenosis [5—7]. Cross-sectional echocardiography, by enlarging our field of vision, generally permits an entire area of obstruction to be encompassed within the plane of a single ultrasonic scan. This allows comparison of the area of obstruction with a normal outflow tract both proximal and distal to this region. In addition, more precise characterization of the morphology and extent of valvular lesions — as well as in certain cases, the severity — is made possible by two-dimensional echocardiography. In this report, we will review our experience using cross-sectional echocardiographic systems to detect and characterize areas of valvular left ventricular obstruction, as well as valvular right ventricular obstruction.
