PRENATAL SONOGRAPHIC DETECTION OF CARDIAC ANEURYSMS AND DIVERTICULA

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 divertriculum protruding beneath the tricuspid valve annulus. All three continued to term and at no time demonstrated cardiovascular compromise.
