Fetal cardiac evaluation by two-dimensional and time-motion echocardiography has been possible for some time, and with present technology has been proven to give exquisite definition of fetal cardiac anatomy. In the following report, the diagnosis and localization of multiple fetal intracardiac tumors illustrates the capabilities of current ultrasound technique and technology.
REPORT OF A CASEA 23-year-old gravida 3, para 2, woman noticed decreased fetal movement two weeJ.. --s prior to delivery and consulted her physician who found the fetu s to be tachycardic and the fundal height to be greater than expected for dates . . The patient was referred to the University of Colorado Health Sciences Center for an ultrasound examination which revealed a vertex singleton with a biparietal diameter of 8 em, head circumference of 28 em, abdominal diameter of9.5 em, abdominal circumference of28 em, and femur length of5.9 em, consistent with a gestational age of 31.5 weeks. In addition to polyhydramnios, there was marked fetal hydrops with ascites, pleural effusions, and skin edema. Fetal heart rate was over 200 beats per minute (bpm) and regular. Fetal cardiac examination showed two solid 1.2-cm-diameter eclmgenic intracardiac masses, one originating from the right side of the interventricular septum near the tricuspid valve and the other involving the mitral valve below the aortic root. Both atria, atrioventricular valves, and semilunar valves appeared to be normal. The left and right ventricles were normal in size and wall thickness.Because of the fetal supr.lVentricular tachycardia with accompanying polyhydramnios and fetal hydrops, the mother and infant underwent digitalization, but premature labor prevented the pregnancy from reaching term. The infant was delivered and by physical exam and previous ultrasonography was considered to be a 32-week gestation. The infant was grossly edematous and no dermatologic or optic fundal abnormalities were appreciated. The chest film was normal and an electrocardiogram showed supraventricular tachycardia of the Wolf-Parkinson-White variety.The neonatal eclmcardiogram confirmed the -in utero diagnosis of tumors immediately adjacent to the atrioventricular valves and the aortic valve.
