Key result
Isolated fetal ventricular aneurysms and diverticula appear to progress to term without cardiovascular compromise.
Case Report (n=3)
Prenatally detected isolated ventricular aneurysms or diverticula can have a benign course without cardiovascular compromise through term.
May inform cautious prenatal counseling for isolated cases; leaves open need for larger prospective studies.
We describe three cases of isolated ventricular aneurysm or diverticulum detected antenatally, with subsequent prenatal serial study and postnatal follow-up. Two pregnancies with in utero left ventricular aneurysm, both involving the apex, were referred for fetal atrial arrhythmias at 28 and 25 weeks of gestation, respectively. The aneurysms had a saccular appearance and were thin-walled and hypokinetic. In a third pregnancy, referred for an abnormal four-chamber view, the fetus was found to have a right ventricular aneurysm or diverticulum protruding beneath the tricuspid valve annulus. All three continued to term and at no time demonstrated cardiovascular compromise.

Hornberger et al. (1994) conducted a case report in Fetal ventricular aneurysm or diverticulum (n=3). Prenatal sonographic detection was evaluated on Cardiovascular compromise. Three fetuses with prenatally detected isolated ventricular aneurysms or diverticula all continued to term without demonstrating cardiovascular compromise.
