Echocardiography was used to evaluate the incidence, flow dynamics and morphological characteristics of right ventricular obstruction in 91 patients with hypertrophic cardiomyopathy. Color flow mapping was used to define the sites of obstruction in the left and right ventricles. Ventricular obstruction was considered to be present if the flow velocity was less than 2.0 m/s as measured by continuous wave Doppler. The thickness of both the right ventricular free wall and anterior ventricular septum was measured to assess the magnitude and extent of hypertrophy. Right ventricular obstruction was present in 14 patients of whom 6 (43%) had left ventricular obstruction also. The right ventricular obstructions were found in the outflow tract (9 patients), mid-base septal bulge (2 patients) and apical trabecular region (3 patients). Doppler waveform was confined to systole in all patients with obstruction in the outflow tract and in one of the patients with mid-base septal bulge. Moreover, the flow wave persisted into early diastole in 4 patients, including 2 with apical trabecular obstruction. The thickness of both the right ventricular free wall and anterior ventricular septum suggested that these hypertrophied regions were the sites of right ventricular obstruction. Thus, echocardiography was useful in evaluating right ventricular obstruction in hypertrophic cardiomyopathy. |
