Ventricular dimensions and wall motion assessed by echocardiography in patients with arrhythmogenic right ventricular dysplasia

Eur Heart J. 1988 Dec;9(12):1291-302. doi: 10.1093/oxfordjournals.eurheartj.a062446.


Twenty patients with arrhythmogenic right ventricular dysplasia (ARVD) and 20 healthy volunteers underwent cross-sectional echocardiographic examination for the assessment of ventricular dimensions and wall motion. Right ventricular cavity diameters and wall segments were selected from the inflow and outflow tracts and the right ventricular body. The measurement error for measuring cavity dimensions was low throughout and the reproducibility of wall motion scoring was high in both the normal subjects and the patients. All except one patient had increased dimensions and/or abnormal wall motion in the right ventricle. The right ventricular inflow tract was dilated in nine patients, the outflow tract in 11 patients and the short- or long-axis diameters of the right ventricular body were increased in seven patients. Right ventricular wall motion abnormalities, being the most frequent finding, ranged from mild hypokinesia only to dyskinesia or sacculations, and were fairly evenly distributed among the segments studied. Left ventricular abnormalities, found in eight patients, were generally mild. Cross-sectional echocardiography thus provides highly reproducible measurements of right ventricular size and contraction patterns even in patients with wall shape deformities, and is therefore a feasible non-invasive method for the evaluation of right-sided myocardial abnormalities in patients with ARVD. The diagnostic accuracy of this technique warrants further clarification.
