Prenatal diagnosis and outcome of congenital cardiac diventiculum / 中华超声影像学杂志

ABSTRACT

Objective To investigate the clinical outcome and prenatal diagnosis feasibility of fetal congenital cardiac diventiculum.Methods The data of 12 fetuses with congenital cardiac diventiculum were retrospectively reviewed.The prenatal and postnatal medical records,including the characteristics of diverticulum,presence of abnormalities,karyotype and the outcomes of each pregnancy were collected.Results The overall incidence of cardiac diventiculum was 0.03％ (12/40 564) and the rate of incidence between left and right ventricle was 2 ∶ 1.Mean size of diventiculum was (69.75 ± 28.73)mm2,mean diameter of the diventiculum neck was (3.58 ± 0.80) mm and mean thickness of diventiculum wall was (1.54± 0.29)mm.Seven cases (58.4％) as an isolated malformation,5 cases (41.6％) combined with cardiac defect and extracardiac abnormalities,2 cases (16.7 ％) with chromosomal abnormalities.Five cases underwent termination of pregnancy,1 case died in uterus and 6 cases were born live.The mean follow-up periods was (62.33±-36.52)month.Of the 6 follow-up cases,4 cases (66.7％) remained asymptomatic,one case underwent drug therapy because of arrhythmia and one case combined with VSD underwent operation.Conclusions Echocardiography could be an useful tool to demonstrate and monitor congenital cardiac diventiculum prenatally and postnatally.The outcome of cardiac diventiculum depends on the size,progression,and the combined abnormalities and complications.
