Objectives Isolated prenatal ventricular disproportion with a dominant right ventricle represents a challenge in decision‐making for both physicians and pregnant women. In the current study, we sought to delineate the postnatal outcomes of these cases. Methods This retrospective analysis included consecutive cases of isolated ventricular disproportion identified using complete fetal echocardiography at the Fetal Heart Center of Xinhua Hospital from January 2014 to October 2017. Postnatal cardiac outcome was examined using transthoracic echocardiography within the first 6 months after birth. Results A total of 90 fetuses were included in the final analysis. The median gestational age (GA) at diagnosis was 29 weeks (range 24 to 36). At postnatal examination, cardiac malformations were detected in 39 cases (43.3%), including 25 (27.8%) cases of congenital cardiac septal defects, eight (8.9%) of persistent left superior vena cava, four (4.4%) of left‐sided obstructive diseases, and one (1.1%) case of coronary fistula. Nineteen cases (21.1%) with fetal cardiac malformations had significant lower GA at diagnosis ( P = .01) and greater right to left ventricle ratio (1.38 vs 1.30, P = .02). Neonatal surgical intervention was not required in any of the cases. Conclusions Isolated prenatal ventricular disproportion with a dominant right ventricle comprises minor postnatal cardiac malformations and doesn't require neonatal intervention.
