Fetal cardiac anomalies involving the atrial septum, ven tricular outflow tract, chambers, and valves are often found in routine examinations. However, prenatal detection of left ven tricular diverticulum (LVD) is rare(1,2). A 28-year-old primipa rous pregnant woman underwent a routine ultrasound in the 22nd week. The fetal heart was found to be topic, with nor mal axis and volume. In the four-chamber view, we observed a structural cardiac abnormality characterized by the presence of an anechoic sac-like formation in the free wall of the left ventricle, near the apex of the heart, rounded and in the form of an exophytic cavity with thin walls, measuring approximately 1.7 cm × 2.0 cm (Figure 1). The two-dimensional examination revealed slight contractility of its walls, and a rhythm consistent with predominance ventricular rate, which would suggest a di agnosis of LVD. Power Doppler ultrasound showed filling of the entire cavity during ventricular systole and emptying during di astole (Figure 2). Spectral Doppler ultrasound showed triphasic flow and high pulsatility within the LVD (Figure 3); the cardiac morphology was otherwise normal. The remaining fetal anatomy was also normal. During prenatal care, the fetal heart showed no significant changes in its dimensions or its other aspects, and.
