Single Right Ventricles Have Impaired Systolic and Diastolic Function Compared to Those of Left Ventricular Morphology

The SRV has reduced contractility and diastolic function compared with the SLV. Ventricular systolic performance in patients with SRVs was poorest before bidirectional cavopulmonary anastomosis, while differences in diastolic function were more prominent after Fontan completion.
