Two‐dimensional measurements included ventricular and outflow tract diameters. Doppler ultrasound was used to measure the flow pattern in the ductus venosus and over the pulmonary and aortic valves, right and left ventricular myocardial performance index and the E/A wave ratio over the atrioventricular valves. Stroke volume, cardiac output and shortening fraction were calculated</italic>.</p> </sec> <sec id="uog12561-sec-0003" sec-type="section"> <title>Results</title> <p id="uog12561-para-0003"> <italic>Median gestational age at evaluation was 27.4 (interquartile range, 24.4–28.9) weeks. RCDH cases had a significantly smaller right ventricle and pulmonary valve diameter. Furthermore, stroke volume and cardiac output from the right ventricle were lower than in controls. Myocardial contractility, however, appeared normal</italic>.</p> </sec> <sec id="uog12561-sec-0004" sec-type="section"> <title>Conclusions</title> <p id="uog12561-para-0004"> <italic>Despite significantly reduced right ventricular dimensions and cardiac output, cardiac contractility was normal in a cohort of fetuses with RCDH.
