title: [The use of echocardiography for diagnosis of right ventricular hypertension (author's transl)].
abstract: Echocardiographic right ventricular wall thickness (RVWT) and right ventricular dimension (RVD) were performed in 65 patients, undergoing diagnostic heart catheterization. Patients were divided in two groups: 28 patients with right ventricular hypertension (group 1) and 37 patients with normal right ventricular systolic pressure (RVSP) (group 2). 24 patients of group 1 (85.7%) had increased RVWT and 34 patients of group 2 (91.9%) had normal RVWT. In group 1 RVSP was significantly correlated with RVWT (r = 0.92; p < 0.001); an inverse correlation was found between RVSP and RVD (r = -0.63; p < 0.001). Non significative correlations were found in group 2. Our study proves that the echocardiographic evaluation of RVWT can be helpful in separating patients with right ventricular systolic hypertension from patients with normal values of RVSP, and that a positive correlation exists between the increase of RVWT and the increase of RVSP.
