Camargo FM, Brizot MDL, Francisco RPV, de Carvalho WB, Ikari NM, Peres SV, Lopes MAB, Lopes LM. Perinatal Results and Long-Term Follow-Up of Fetal Cardiac Tumors: A 30-Year Historical Cohort Study. Arq Bras Cardiol 2024; 121:e20220469. [PMID: 38536996 PMCID: PMC11081142 DOI: 10.36660/abc.20220469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 05/28/2023] [Accepted: 10/04/2023] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND This was a 30-year retrospective cohort study that approximates closely to the natural history of cardiac tumors diagnosed in the fetus, since there was no case of pregnancy interruption. OBJECTIVE To assess morbidity and mortality in the perinatal period and at long term in fetuses diagnosed with cardiac tumor. Our secondary objective was to assess the evaluating factors of perinatal and postnatal results. METHODS This was a retrospective cohort study with 74 pregnant women with an echocardiographic diagnosis of fetal cardiac tumor at two referral centers between May 1991 and November 2021. A descriptive analysis was performed, and data were expressed as absolute (n) and relative (%) frequencies, median and interquartile range. Fisher's exact test was used to evaluate the association of echocardiographic characteristics and clinical manifestations with perinatal and postnatal results. Global survival was calculated using the Kaplan-Meier method and the curves were compared by the log-rank test. The time of follow-up, calculated in months, corresponded to the time elapsed from hospital discharge to current status (survived/ censoring or death). The level of significance was set at 5% (p<0.05). RESULTS Rhabdomyoma is the most common type of cardiac tumor (85%), with a high morbidity (79.3%) and overall mortality of 17.4%. The presence of fetal hydrops was a predictor of death. CONCLUSION The presence of fetal hydrops had an impact on mortality, and hence is an important factor in counselling and determining the prognosis. Most deaths occurred before hospital discharge.

Abstract
AIMS The study aims to evaluate the genetic and clinical outcomes of fetal cardiac rhabdomyoma in our tertiary center. METHODS Data of cases with cardiac rhabdomyoma detected by fetal echocardiography during antenatal follow-up were analyzed retrospectively. RESULTS Nine cases were included in the study. The incidence of cardiac rhabdomyoma was 0.003%. The median fetal diagnosis time was 26th weeks, the most common location was the LV. There was no hemodynamic disorder requiring cardiovascular intervention in any of the cases. Of the eight genetically tested cases, four were tuberous sclerosis complex (TSC) gene-negative, one hereditary TSC2, one de novo TSC1, and two de novo TSC2 gene mutants. Postnatal first-year survival rate of the cases was 88.8%. CONCLUSIONS Cardiac rhabdomyoma is a rare fetal and pediatric pathology that generally is a remarkable finding in the clinical process of TSC. Therefore, cases should be evaluated multisystemically and genetic counseling should be given to the family.

Abstract
BACKGROUND Despite its rare incidence of 1/40,000, fetal cardiac rhabdomyoma (CR) represents the prevailing type of benign cardiac fetal tumors, which commonly affects the ventricles. Fetal CRs rarely occur in the right atrium. Thus, the presentation of atrial fibrillation and premature atrial contractions (PAC) due to a solitary cardiac rhabdomyoma is an extremely rare scenario. Our literature review found that only 2% (1 out of 61) of rhabdomyoma cases were found in the right atrium. The majority of fetal cardiac rhabdomyomas are associated with tuberous sclerosis complex (TSC). CASE PRESENTATION A 7-day-old male neonate presented with arrhythmias and an atrial mass for further evaluation. Echocardiography revealed a hyperechoic, round, uniform right atrial mass (25 mm). An abdominal and testicular ultrasound showed multiple thin-walled cortical cysts in both kidneys and a scrotal hydrocele, respectively. His laboratory workup was insignificant except for hypomagnesemia. Electrocardiography revealed junctional rhythm and PACs with wave distortions. A brain magnetic resonance imaging scan revealed multiple subependymal lesions on the frontal and occipital horns of the lateral ventricles. These findings (Fig. 1), along with a family history of TSC, confirmed the diagnosis of TSC with associated CR. The patient was treated symptomatically with an anti-convulsant and monitored with regular follow-ups. Surgical resection was not required. CONCLUSION Despite CR's predominance in the ventricles, a diagnosis of rhabdomyoma should be kept in mind in the presence of a solitary atrial mass and PACs. Physicians should evaluate systemic findings related to TSC and provide appropriate follow-up and family screening. Surgical resection is not always required, and symptom management can be achieved through medical treatment alone.

Abstract
BACKGROUND AND PURPOSE Strong emphasis has been placed recently on early (4 postnatal months) detection of tuberous sclerosis complex and the introduction of antiepileptic treatment before seizure onset. This objective can be achieved prenatally: Cardiac rhabdomyomas and the major diagnostic tuberous sclerosis complex sign are detected during fetal ultrasound, and prenatal MR imaging allows detection of cerebral major manifestations: cortical tubers, subependymal nodules, and subependymal giant cell astrocytomas. MATERIALS AND METHODS We retrospectively reviewed 50 fetuses with ultrasound-detected cardiac tumors at 19-36 gestational weeks (median, 31 weeks). MR imaging with the use of 1.5T scanners was performed at 24-37 gestational weeks (median, 34 weeks). RESULTS In 11 fetuses (22%), cardiac tumors remained the only criterion. In remaining 39 fetuses (78%), MR imaging revealed a prenatal diagnosis of tuberous sclerosis complex, having shown an additional 1-3 major criteria: subependymal nodules in all cases (39/39 = 100.0%), subependymal giant cell astrocytomas in 6 (6/39 = 15.4%), and cortical tubers in 24 (24/39 = 61.5%). Radial migration lines and cerebellar tuber, not published so far, were shown in 1 case each. CONCLUSIONS A schedule of proper care of children with tuberous sclerosis complex can be established during the perinatal period due to education of women to report for mandatory ultrasound examinations during pregnancy, the good quality of ultrasound, and referral to MR imaging if a cardiac tumor is depicted on ultrasound. Gynecologists and pediatric cardiologists performing fetal ultrasound and radiologists performing prenatal MR imaging are a key to early diagnosis of tuberous sclerosis complex in many cases.

Abstract
OBJECTIVE To investigate the prenatal imaging characteristics, genetic characteristics and pregnancy outcome of fetuses with cardiac rhabdomyoma. STUDY DESIGN The prenatal ultrasound, cranial MRI imaging information and genetic test results of 35 fetuses prenatally diagnosed with cardiac rhabdomyoma were collected and retrospectively analyzed, and the pregnancy outcome was followed up. RESULT Cardiac rhabdomyomas mainly occurred in left ventricular wall and ventricular septum; cranial MRI imaging was found abnormal in 38.1% (8/21) of the fetuses; genetic test was found abnormal in 58.82% (10/17) of the fetuses; the fetus was born in 12 cases and the pregnancy was terminated in 23 cases. CONCLUSION TRIO whole exome sequencing (TrioWES) is recommended as the genetic test regime for cardiac rhabdomyoma. The comprehensive evaluation of prognosis of fetuses needs to consider the genetic results and whether the brain is involved; the prognosis of fetuses with simple cardiac rhabdomyoma is good.

Abstract
OBJECTIVE This study aims to determine the characteristics and outcome of prenatally diagnosed cardiac rhabdomyomas. STUDY DESIGN This retrospective descriptive study includes cases referred to our university hospital. We studied sonographic characteristics of rhabdomyoma along with the neonatal outcome. RESULTS Eight cases were included, with a mean gestational age at diagnosis at 31 weeks of gestation and five patients diagnosed after 32 weeks. We noted a male gender in 75%, multiple rhabdomyoma in 50%, mostly situated in the interventricular septum (41%) and valvular regurgitation in 25%. Most patients delivered at term, including five cesareans (62.5%). Six babies survived (75%); three of them were later diagnosed with tuberous sclerosis (50%). CONCLUSION Cardiac rhabdomyoma have variable ultrasound features. The usual favorable outcome can however be complicated by neonatal death (12%), valvular regurgitation and cerebral tuber.

Abstract
Background Cardiac tumors in infants and children are rare. The most common cardiac tumor is rhabdomyoma, which may be associated with tuberous sclerosis. However, not all cardiac rhabdomyomas are pathognomonic for tuberous sclerosis, and not all congenital cardiac tumors are rhabdomyomas. During the prenatal period, early cardiac tumor detection provides important information about fetal wellbeing, delivery planning, and necessary postnatal care. Case presentation We report a 36-year-old African American pregnant women. At 32 weeks 5 days gestational age, the male fetus had a fetal echocardiogram due to fetal arrhythmia. The fetal echocardiogram showed two small echogenic, RV apex and septal masses, suspicious of rhabdomyomas. After a routine pregnancy and a normal spontaneous vaginal delivery (39 weeks 1 day), the male baby was admitted to the neonatal intensive care unit for further monitoring and postnatal evaluation. Conclusions Rhabdomyomas are extremely rare and unique tumors. These tumors are very dangerous, but they usually regress after birth. During the prenatal period, early cardiac tumor detection provides important information about fetal wellbeing, delivery planning, and necessary postnatal care. We present this case to share our findings with our pediatric colleagues. Although a rarely reported case, we hope this cardiac rhabdomyoma case report and literature review can increase cardiac tumor awareness.

Abstract
Tuberous sclerosis (TSC) is a multisystem autosomal dominant genetic disorder due to loss of function of TSC1/TSC2 resulting in increased mTOR (mammalian target of rapamycin) signaling. In the brain, TSC is characterized by the formation of specific lesions that include subependymal and white matter nodules and cortical tubers. Cells that constitute TSC lesions are mainly Giant cells and dysmorphic neurons and astrocytes, but normal cells also populate the tubers. Although considered as a developmental disorder, the histopathological features of brain lesions have been described in only a limited number of fetal cases, providing little information on how these lesions develop. In this report we characterized the development of TSC lesions in 14 fetal brains ranging from 19 gestational weeks (GW) to term and 2 postnatal cases. The study focused on the telencephalon at the level of the caudothalamic notch. Our data indicate that subcortical lesions, forming within and at the vicinity of germinative zones, are the first alterations (already detected in 19GW brains), characterized by the presence of numerous dysmorphic astrocytes and Giant, balloon-like, cells. Our data show that cortical tuber formation is a long process that initiates with the presence of dysmorphic astrocytes (by 19–21GW), progress with the apparition of Giant cells (by 24GW) and mature with the appearance of dysmorphic neurons by the end of gestation (by 36GW). Furthermore, the typical tuberal aspect of cortical lesions is only reached when bundles of neurofilament positive extensions delineate the bottom of the cortical lesion (by 36GW). In addition, our study reveals the presence of Giant cells and dysmorphic neurons immunopositive for interneuron markers such as calbindin and parvalbumin, suggesting that TSC lesions would be mosaic lesions generated from different classes of progenitors.

Abstract
Cardiac tumors in neonates and infancy are one among the many known congenital cardiac diseases. Although fetal cardiac tumors are rare, there is increased detection because of expertise in echocadiographic examination. Rhabdomyomas are the most common cardiac tumors among infants and children. Here, we describe twin neonates who had multiple cardiac tumors. This kind of presentation appears to be a very rare situation.

Abstract
Cardiac rhabdomyoma is the most prevalent cardiac tumors in the pediatric population, in close association with tuberous sclerosis complex. It is usually detected antenatally or postnatally by echocardiography. Clinical presentations depend greatly on the size and position of the tumor mass. Interestingly, rhabdomyoma has a propensity to regress spontaneously and is not usually operated upon, unless the patient becomes hemodynamically compromised. Herein, we report an unusual case of surgically treated cardiac rhabdomyoma in a baby boy presented at birth with a progressive enlarging intraventricular mass, complicated with left ventricular outflow tract obstruction 7 weeks later. Histopathological examination of the intracardiac mass revealed sheets of tumor cells with spider-like morphology (known as "spider cells"), confirmed the diagnosis of rhabdomyoma. Close disease monitoring of patient's hemodynamic status in a newly diagnosed cardiac rhabdomyoma is inevitable as the tumor, although rare, may progress.

Abstract
Abstract
Background
Congenital tumors, including mesenchymal rhabdomyoma, are highly infrequent. The combination of a congenital tumor and rhabdomyoma is rarer yet, even more so when primary origin is in the heart.
Case presentation
We present a case of fetal hydrops fetalis, wherein the post-mortem exam revealed a cardiac tumor more than twice the size of the heart itself; histological study confirmed primary rhabdomyoma involving the left ventricle.
Conclusion
It is essential to keep in mind that fetal tumors should always be differentiated from malformations; in fetuses tissue immaturity must be taken into account for categorization; despite benign labeling, they can be lethal.

Abstract
OBJECTIVE Rhabdomyomas are the most common type of prenatal cardiac tumors. When isolated, 50% to 70% are related to the tuberous sclerosis complex (TSC). The aim of this study was to reinforce the importance of additional clinical data in patients with prenatal heart tumors. METHODS From 2010 to 2017, 10 prenatally detected cardiac tumors were referred to the Genetics Department, and a complete family history was taken. Postnatal echocardiographic and full clinical evaluation were completed. Next generation sequencing (NGS) of the TSC1 and TSC2 genes was performed. RESULTS The 10 cases were postnatally confirmed as rhabdomyomas. Four de novo and four family cases were detected, and only one patient was previously aware of the TSC diagnosis. Molecular analysis by NGS was performed in four patients with three TSC2 mutations, two of which were previously reported and one not. DISCUSSION Prenatal cardiac tumors are associated with TSC in 60% of cases. Prenatal diagnosis of cardiac tumors permits a further analysis of family members using the fetus as a clue for familial disease diagnosis.

Abstract
Cardiac rhabdomyomas are the most common fetal cardiac tumor. They can be detected in the second and third trimesters. Rhabdomyomas are most commonly associated with the genetic disorder tuberous sclerosis complex. When associated with tuberous sclerosis complex, cardiac rhabdomyomas usually regress within the first few years of life, without complications. Symptoms depend on the size, number, and location of the rhabdomyomas. A case report of multiple cardiac rhabdomyomas that was found at 35 weeks’ gestation and is discussed.

Abstract
Tuberous sclerosis complex is a dominantly inherited genetic disorder of striking clinical variability. It is caused by mutations in either TSC1 or TSC2 gene, which regulate cell growth and proliferation by inhibition of mTORC1 signaling. TS is characterized by the development of benign tumors in many tissues and organs and its neurological manifestations include epilepsy, autism, cognitive and behavioral dysfunction, and giant cell tumors. With mechanism-based mTOR inhibitors therapy now available for many of its manifestations, early diagnosis of TSC is very important in order to offer appropriate care, long-term surveillance and parental counseling. Fetal ultrasound and MRI imaging techniques have evolved and may capture even earlier the following TSC-associated lesions: cardiac rhabdomyomas, subependymal nodules, cortical tubers and renal cysts. Often these represent an incidental finding during a routine ultrasound. Furthermore, in the past decades prenatal molecular diagnosis of TSC has emerged as an important option for families with a known affected member; however, the existing evidence with regards to the clinical characteristics and long-term outcome of babies diagnosed prenatally with TSC is yet limited and the path that follows early TSC detection merits further research.
