Perinatal diagnosis of cardiac tumors

Abstract

Cardiac tumors are detectable as early as 22 weeks of gestation. Presenting symptoms may be arrhythmia, dysfunction of the atrioventricular valves, pericardial effusion and fetal hydrops. The most common perinatal diagnosis is rhabdomyoma, which is often associated with tuberous sclerosis. Sequential examination in high risk patients should be considered as most tumors increase in size during pregnancy and may become evident in late second and third trimester of pregnancy. Postpartum, however, regression of tumor size is common.
