Although fetal primary cardiac tumors are rare, they are usually detected during fetal echocardiography. The vast majority of primary cardiac tumors are benign, with rhabdomyomas being the most common cardiac tumors in the prenatal period, followed by teratoma, fibroma, and hemangioma. Cardiac rhabdomyomas are usually numerous, depending on the location, they can cause hemodynamic disorders and arrhythmias in the antenatal and early postnatal period.[1] Cardiac rhabdomyomas are frequently observed together with tuberous sclerosis. Other components of the tuberous sclerosis complex are tubercles and nodules in the brain, spots on the skin and renal angiomyolipomas, and fetuses with cardiac rhabdomyoma should be carefully screened for these anomalies.[1,2] With this case report, we aimed to share the clinical presentation and results of a cardiac rhabdomyoma case that we followed in our clinic.


Computer-based and ultrasonography records of an isolated cardiac rhabdomyoma case, who applied to Prof. Dr. Cemil Taşçıoğlu City Hospital Gynecology and Obstetrics Clinic - Perinatology outpatient clinic at the 34th week of pregnancy, were scanned retrospectively from the hospital software and the history of the ultrasonography device. Fetal ultrasonography examination was performed using Mindray Resona 7 device and its 1.2-6 MHz convex abdominal probe.


The 30-year-old patient, who had no additional features in her obstetric history except for one abortion, was referred to our clinic with the suspicion of a cardiac mass. She was at 34 weeks of gestation according to the date of her last menstrual period. Fetal echocardiography revealed multiple rhabdomyomas, the largest of which was 12*6.6 mm in the left ventricle, 10*9 mm in the right ventricle, and 15*10 mm in the apex of the interventricular septum (Figure 1-2). Although there was a rhabdomyoma of 7.7*4.6 mm in front of the aortic valve at the exit of the left ventricle, the vessel sizes were normal in 3 vessels-trachea sections. No nodular image was observed in the cranial examination. Examination of the fetal kidneys was normal in size and anatomically. Umbilical artery, bilateral uterine artery and middle cerebral artery Doppler flows were normal. The patient and her husband did not want to have an invasive diagnostic test in the prenatal period for the differential diagnosis of tuberous sclerosis. Pediatric cardiovascular surgery was consulted about the patient, and postnatal emergency intervention was not considered as the current pathology did not cause any outlet obstruction.During the examination, on the patient’s description of itching on the hands and feet, a diagnosis of intrahepatic cholestasis of pregnancy was made in the further examination. One week later, due to pharmacotherapy-resistant pruritus, high total serum bile acids and unreliable NST, a live female baby was delivered at 35 weeks. The baby’s 1st and 5th minute APGAR scores were 7 and 8, respectively. In the first examination, it was learned that there was no pathological cardiac listening finding. In the first echocardiographic examination, a large number of hyperechoic masses thought to be rhabdomyomas, the largest of which was 16*18mm in diameter, were detected in the intracardiac region, which did not cause heart failure, ventricular tachycardia, valve stenosis, and left and right ventricular outflow tract stenosis. No intervention was required. It was learned that rhabdomyomas spontaneously regressed without the need for any treatment in the pediatric cardiology follow-up of the baby after birth.


Rhabdomyomas may be in the form of multiple intramural lesions in the right and left ventricles, or they may be located in the interventricular septum or atrium. Although they can be seen as a single mass, they often involve the heart multiple or diffusely. Fetal echocardiography is a sensitive method for detecting cardiac tumors. Especially during the second-trimester ultrasonography, 4-chamber and 3-vessels-trachea sections are valuable in detecting cardiac tumors. Tuberous sclerosis accompanies 30-50% of cardiac rhabdomyomas, which is why these patients deserve a detailed evaluation and follow-up.[1,2] 


Cardiac rhabdomyomas may be symptomatic depending on the size and location of the tumor, although by their nature they tend to regress spontaneously after the end of the hormonal effect of pregnancy after delivery. For these reasons, the growth status of the tumor should be evaluated in antenatal follow-ups and it should be recommended to give birth in a tertiary center by deciding with the family.
