Female conjoined throraco-omphalopagus twins were delivered via cesarean section at 35 weeks 5 days gestational age to a 38-year-old mother who received standard prenatal care. After resuscitation, the twins were transferred to the neonatal ICU, where they remained for monitoring and growth as they were assessed for potential separation. CT angiography was performed at 3-4 months of life using a staged approach. Selective IV and oral contrast administration was used over two visits to delineate shared and non-shared structures. Most significantly, there was a single shared liver with anomalous hepatic venous drainage. Twin A had three normal caliber hepatic veins draining into a normal IVC, but a large branch of the middle hepatic vein traversed midline into Twin B and received hepatic venous drainage from Twin B via numerous anomalous vessels. Twin B had a normal IVC but three diminutive hepatic veins, thought to be due to reduced venous drainage as a result of the anomalous shared vasculature. After multidisciplinary discussion, interventional radiology was consulted for hepatic venogram and intervention as needed. The anomalous communicating vessels were identified on hepatic venogram via Twin A femoral approach. Occlusion of the anomalous branches was achieved with serial embolization of the primary draining vessel on the Twin A side using Amplatzer vascular plugs. Successful occlusion was confirmed on venography after the final embolization procedure. Follow-up Doppler ultrasound exams confirmed improved hepatic venous outflow in Twin B, initially with reversal of flow in the anomalous veins back toward the IVC of Twin B, followed by nonvisualization of the anomalous veins on later exams. CT angiography later showed enlarged caliber of the native Twin B hepatic veins. Following the optimization of hepatic venous outflow, the multispecialty surgical team proceeded with separation. The twins were separated at 13 months of age without complication. In addition to restoring venous outflow to allow for a successful surgical outcome, it was noted that the Amplatzer devices were used as surgical landmarks during separation for identification of shared anatomy. Through careful planning and execution, diagnostic and interventional radiology techniques played a critical role in this successful outcome. Read More

Papillary fibroelastomas are benign primary cardiac tumors that usually arise from the valve apparatus and are rare in the pediatric population. Involvement of the tricuspid valve is even rarer, with only a few cases reported in the literature. We present the case of an 11-month-old female referred by her pediatrician after a non-cardiovascular acute visit to investigate a murmur noted since birth. The patient was asymptomatic. Family history was negative for congenital heart disease, seizures or genetic disorders. Her physical exam revealed a soft holosystolic murmur at the left lower sternal border but was otherwise normal. Initial work up with ECG and echocardiogram revealed limb lead reversal and a large mass in the right ventricle. Subsequent MRI showed a mobile 15mm oval mass along the septal surface of the right ventricle, in close proximity to the tricuspid valve, without valve inflow or right ventricular outflow tract obstruction. The mass was faintly visualized on TFE, isointense on T1, centrally-hyperintense and peripherally-hypointense on T2, and peripherally enhancing on post-contrast images. After a multidisciplinary review of the case, the decision was made to proceed with surgical resection. A preoperative CT of the chest did not reveal pulmonary embolism. During surgery, the mass was attached to the septal leaflet and the chordae of the tricuspid valve but not to the septum. Visually, the mass was compatible with a fibroelastoma. Off-bypass intraoperative transesophageal echocardiogram showed moderate tricuspid regurgitation that required on-bypass annuloplasty. Pathology confirmed the diagnosis of papillary fibroelastoma. There were no surgical complications. She was discharged on postoperative day 6 and had been doing well until her most recent follow-up four months after surgery. Papillary fibroelastomas are typically asymptomatic, although they carry potential risks for complications such as pulmonary or systemic emboli, depending on their location. MRI is a valuable examination that can characterize intracardiac tumors and thrombi. To our knowledge, this is the first report of a pathology-proven papillary fibroelastoma of the tricuspid valve characterized by MRI in such a young child Read More

Norwood procedure is a 3-stage surgical palliation for patients with functionally single ventricle anatomy, most commonly hypoplastic left heart syndrome. Complications after stage I operation are not uncommon and include Blalock Taussig Thomas (BTT) /Sano shunt abnormalities, Damus-Kaye-Stansel (DKS) anastomotic narrowing, and neo-aortic arch /branch vessel stenosis. Transthoracic echocardiography (TTE) is traditionally the mainstay for evaluation. The purpose of our study is to compare Gated Cardiac Computed Tomographic Angiography (CCTA) with TTE when evaluating post-operative complications after stage I Norwood procedure and implications of CCTA findings on management.
