We present a case of an 11-year-old Indonesian female who was referred to our facility after surgical excision of brain abscess. The patient has been previously diagnosed with right atrial isomerism, complete atrioventricular septal defect, and L-Transposition of great arteries. Multiple staged surgeries are required for the management of this condition.
Coronary ostial atresia seen with pulmonary atresia and coronary-cameral fistulae or, more rarely, in isolation manifested as left main coronary artery atresia, is well described. We describe the clinical course and post-mortem findings in a neonate who suffered a fatal cardiac arrest and was found to have congenital absence of both coronary ostia in a single/common coronary system.
Aneurysms of the right atrium are rare in the paediatric population. We report a case of a foetal diagnosis of right atrial aneurysm with associated atrial tachycardia in foetal and postnatal life. Unique to our case are the findings of isolated pericardial effusion without hydrops fetalis and the development of aortic coarctation in postnatal life.
Retroaortic course of left innominate vein is a rare venous anomaly which is usually associated with CHD. Isolated retroaortic innominate vein is exceedingly rare with only a handful of reported cases. We report an otherwise healthy newborn with isolated retroaortic innominate vein and right aortic arch, a combination which has previously not been reported.
Biatrial drainage of the right superior caval vein is an extremely rare cardiac anomaly that generally presents in childhood. We present a case of anomalous connection of the right superior caval vein with superior sinus venosus atrial septal defect and partial anomalous pulmonary venous return in a 5-month-old male presenting with unexplained cyanosis and hypoxia.
We report the case of a 14-year-old female who had tetralogy of Fallot along with anomalous origin of the left pulmonary artery from the ascending aorta with co-dominant double aortic arch forming a complete vascular ring compressing the oesophagus along with a left main coronary artery to right ventricular outflow tract fistula. She underwent surgical correction without conduit placement.
Isolation of the left innominate artery from the right aortic arch is a rare anomaly. Herein, we present an even rarer case of incomplete isolation of the proximal left innominate artery with the right aortic arch in a 3-month-old female infant with a double-outlet right ventricle and pulmonary stenosis. Surgical repair at 6 months of age was successful, leading to the restoration of adequate flow in the left arm.
Unilateral interruption of pulmonary artery is a rare congenital anomaly which is usually associated with other congenital heart disease. Even more rarely it may occur in isolation. Most of the cases are incidentally detected in adulthood. Some cases develop pulmonary hypertension for yet unknown reasons; such cases usually present in infancy with right heart failure. Surgical correction in such cases is associated with adverse outcomes. Heart lung transplantation should be considered in such patients. We report a 3-year-old boy with interruption of right pulmonary artery with severe pulmonary hypertension and right heart failure who was considered for heart lung transplantation.
We present the second reported case of left pulmonary artery sling with dextrocardia, right pulmonary hypoplasia, and total pulmonary venous connection in a fetus. This case highlights the importance of the determination of pulmonary artery arrangement by fetal echocardiography if right pulmonary hypoplasia and/or congenital heart disease is suspected.
We report a rare case of anomalous aortic origin of the right coronary artery from the posterior/non-coronary sinus of Valsalva in a 9-year-old male diagnosed during the workup of premature ventricular contractions. The finding was initially noted on transthoracic echocardiogram and further confirmed with computed tomography. The anomalous coronary artery shows a wide ostium with no intramural or interarterial course.
Cyanosis in a newborn is commonly due to intracardiac shunts or duct-dependent lesions. Systemic venous anomalies are uncommon and sinus venous atrial septal defects do not usually present with cyanosis. We report the case of a 4-month-old female with persistent hypoxemia due to a right superior vena cava overriding a superior sinus venous atrial septal defect resulting in a right to left shunt.
An isolated left common carotid artery is very rare, and only 13 cases have been reported thus far. All those cases were accompanied by a right aortic arch and aberrant left subclavian artery, and the connecting vessel between the pulmonary artery and left common carotid artery was thought to be ductal tissue. However, there have been no reports that have followed the natural closure of this vessel. We present a case in whom we could observe the closing process of this vessel at the connection between the left common carotid artery and main pulmonary artery in association with a tetralogy of Fallot.
Intracardiac teratomas are rare primary tumours. We report the case of an infant prenatally diagnosed with an isolated multi-cystic mass developed in the right ventricle causing neonatal refractory ventricular arrhythmia. Despite rescue extracorporeal support and partial surgical resection, he died as almost all the previous reported perinatal intracardiac teratomas whatever the prenatal tolerance and the size of the tumour. The common poor outcome of fetal intracardiac teratomas should be known when counselling parents during pregnancy.
A newborn with prenatally diagnosed dysplasia of both atrioventricular valves presented after birth with signs and symptoms of low cardiac output, severe regurgitation of both mitral and tricuspid valves. This combination is as rare as challenging, since it regards both the timing and management of this complex cardiac malformation. We report an early surgical repair of both atrioventricular valves in a symptomatic newborn, which improved his clinical status and, so far, delayed valve replacement.
Congenital complete tracheal rings are usually associated with pulmonary slings. We report a rare association of congenital complete tracheal rings with hypoplastic left heart variant. A term infant with diagnosis of a mildly hypoplastic mitral valve, unicuspid aortic valve, and moderately hypoplastic aortic arch with severe coarctation underwent a hybrid procedure initially. Upon failing extubation attempts, complete tracheal rings were seen on direct laryngoscopy. The combination of the lesions resulted in a poor outcome. In patients with failure of extubation post-cardiac surgery, a diagnosis of complete tracheal rings should be included in the differential and a direct laryngoscopy should be considered.
Cor triatriatum sinister is a rare congenital abnormality, with varying signs and symptoms related to the anatomic features and the components of the accompanying cardiac abnormalities. We present a 3-year-old girl who underwent successful simultaneous operation with complete loss of the membrane and ligation of vertical vein by anomalous venous return. The principles for surgical management of cor triatriatum can be summarised as radical resection of the membrane and correction of other intracardiac anomalies.
Septum primum malposition defect is an extremely rare CHD and is often found in patients with visceral heterotaxy, particularly of the polysplenia type. We describe a unique patient with dextrocardia, situs inversus totalis, and bilateral superior vena caval veins without heterotaxy syndrome who was diagnosed with an interatrial defect and partial anomalous pulmonary venous drainage due to malposition of the septum primum.
In this report, a unique case of a symptomatic vascular ring formed by right aortic arch, aberrant left subclavian artery, and left ligamentum arteriosus in which there is atresia of the proximal left subclavian artery is described. Imaging modalities were non-diagnostic and the patient was sent to surgery based on strong clinical suspicion. Her anatomy was delineated in the operating room and the ring was successfully repaired.
A male neonate with d-transposition of the great arteries was diagnosed with the concomitant anomaly of left circumflex aortic arch and right-sided ductus arteriosus, which formed a vascular ring. Initial postnatal echocardiography had demonstrated an obscured aortic isthmus mimicking coarctation of the aorta, which could be a diagnostic clue to circumflex aortic arch.
Pulmonary atresia with intact ventricular septum may be complicated by coronary aneurysms and myocardial ischaemia. We report a case of an acquired postoperative right ventricular outflow tract aneurysm with communication to the left ventricular outflow tract. Multimodality imaging helped in the characterisation of this structural abnormality, which led to treatment modification of the patient.
