Right atrial appendage aneurysm complicated with atrial septal defect: A rare case report

Right atrial appendage aneurysms (RAAAs) are rare heart malformations, presenting as isolated anomalies or co-existing with other structural heart diseases. We describe a rare case of RAAA complicated with an atrial septal defect (ASD). The diagnosis was established using transthoracic echocardiography and confirmed using cardiac magnetic resonance imaging. To treat the ASD and reduced right atrium volume load, ASD transcatheter closure was performed. On echocardiography performed 3 months post discharge, the RAAA was observed to have reduced in size compared to that presurgery. Six years later, she was in good condition without any adverse events.     

Giant right atrial aneurysm: case report

A 15-month-old boy with atrial fibrillation was found to have gross cardiomegaly on a chest radiography; further evaluation by echocardiography showed a giant right atrial aneurysm which is in the form of a cyst like lesion. The patient underwent successful surgical reduction of the right atrium converting his heart rhythm to normal. The operative measure was taken to prevent thrombus formation in the right atrium and lower the risk of atrial arrhythmias. The morphologic features of the resected atrial tissue showed a thin wall with a central aneurysm and focal endocardial fibrosis without inflammatory response consistent with a diagnosis of idiopathic dilatation of the right atrium.     

Giant right atrial aneurysm: a case report

Giant right atrial aneurysm is a very rare congenital heart defect. We report a case which was diagnosed during fetal life and operated on at 4 months of age with excision of the aneurysmal part and pericardial patch closure. Early repair is recommended to prevent late complications such as arrhythmias and thromboembolic phenomena.     

Diagnosis of atrial septal aneurysm by two-dimensional echocardiography--a case report.

A patient who was evaluated for a syncopal episode was found by two-dimensional (2D) echocardiography to have an aneurysm of the atrial septum. The atrial septal aneurysm appeared as a localized outpouching of the atrial septum that protruded into the left atrium during systole and into the right atrium during early diastole. The 2D echocardiography permits the definitive diagnosis of this condition by a noninvasive technique.     

Right atrial hemangioma presenting as pericardial tamponade. A case report

Intracardiac haemangioma is a very rare benign primary cardiac tumour. A 40-year-old patient, with no notable history, presented with chest pain, accentuated by deep inspiration, associated with NYHA stage III dyspnoea. Physical examination revealed signs of right heart failure and electrocardiogram showed low voltage with diffuse repolarization disorders. Chez x-ray showed a cardiothoracic index CTI > 0.70, and enlarged right margins. A large pericardial effusion with a tumour mass filling the right atrial cavity was discovered on transthoracic echocardiography. Chest computed tomography demonstrated the tissue origin of the tumour and suggested extension to the inferior vena cava and hepatic veins. The patient was referred to a surgeon for tumour resection. Histological examination revealed intracardiac capillary haemangioma. Five month postoperative follow-up did not reveal any abnormalities.     

Right atrial thrombus associated with combined valvular disease: case report

A 77-year-old man had a large right atrial (RA) thrombus associated with a combined mitral and tricuspid valve disease. Echocardiography showed a large, immobile, non-homogeneous, irregularly surfaced mass in the dilated RA, and prolapse of the anterior mitral leaflet resulting in massive mitral regurgitation. Computed tomography (CT) revealed a laminated structure with calcification and distinct margins, without invasion to the wall of the RA. On the basis of these echocardiographic and CT findings, a diagnosis of combined mitral and tricuspid valvular disease complicated with RA thrombus was made. Removal of the RA thrombus, mitral valve replacement and tricuspid annuloplasty were performed simultaneously, with successful outcome.     

Right atrial thrombus masquerading as intracardiac cyst: a case report

Intracardiac cystic lesions are rare. Hydatid disease, blood cysts and bronchogenic cysts in various chambers of the heart have been reported. Right atrial thrombus presenting as a cystic lesion on echocardiogram has not been reported. We describe a patient with mitral regurgitation in atrial fibrillation with a right atrial cyst, which was found to be a cavitating thrombus.     

Right atrial myxoma. Review of the literature and a case report

On the basis of a personal observation and from a complete review of the existing literature, clinical and instrumental findings of right atrial myxoma are described. The clinical presentation appears to be rather characteristic. The presence of systemic symptoms, peripheral venous hypertension and/or right heart failure without apparent cause are a clue to the diagnosis especially in an adult woman. The presence of abnormal sounds and/or murmurs in the tricuspid area and intermittence of the signs of obstruction are further support to the diagnosis. The diagnosis can always be made non-invasively by echocardiography, though some pitfalls seem to be inherent to the M-mode technique. The accuracy of two-dimensional echocardiography in the diagnosis of the right atrial myxoma is such that no further investigations are necessary before surgery.     

Right atrial thrombus following surgical closure of atrial septal defect--a case report

A case of an 11-year-old girl with atrial septal defect is described. The patient underwent surgical closure of the defect, which was complicated by asymptomatic thrombus formation in the right atrium. Anticoagulant therapy was initially successful, but thrombus recurred. Surgical thrombus removal was successful.     

Right atrial aneurysm after chest trauma: late presentation

We report the case of a 59-year-old patient, with a history of severe chest trauma with rib fractures at the age of 20 and recent onset of fatigue and palpitations, who was diagnosed with atrial tachycardia, which was converted pharmacologically. Cor triatriatum or Ebstein's anomaly were suspected on initial imaging studies (transthoracic echocardiography and MRI). Due to recurrence of arrhythmia, he subsequently underwent repeat echocardiographic evaluation, which established a diagnosis of right atrial aneurysm. The arrhythmia was converted electrically. The patient has remained asymptomatic during 18 months of follow-up, without arrhythmia recurrence, medicated with carvedilol (after an initial period with amiodarone) and warfarin.     

Right ventricular aneurysm due to myocardial fatty infiltration: report of a case

A case of right ventricular aneurysm due to myocardial fatty infiltration was reported. A 39-year-old man was admitted to our hospital for evaluation of several episodes of syncopal attack presumably induced by malignant arrhythmia. There were frequent observations of ventricular premature beats, which occurred occasionally in couples. Cardiac catheterization disclosed the aneurysm situated at the outflow tract of the right ventricle. Aneurysmectomy was performed and the ventricular premature beats and syncopal attacks were effectively abolished. Etiology of the aneurysm was proved to be a fatty infiltration in the myocardium. To the best of our knowledge, there has been no case report of right ventricular aneurysm due to fatty infiltration in the myocardium.     

Right atrial myxoma with atrial septal defect: A case report and review of the literature

We report the case of a 63-year-old woman presenting with progressive dyspnea of insidious onset culminating in severe central cyanosis. Conventional studies including M-mode echocardiography did not point to the diagnosis. At cardiac catheterization a large right atrial myxoma producing partial dynamic tricuspid obstruction was discovered along with an atrial septal defect with a right to left shunt. After successful surgical excision of the tumor and repair of the atrial septal defect, the patient has been totally relieved of her presenting symptoms.     

Partial resection of atrial septal aneurysm with multiple fenestrations--a case report

Aneurysms of the interatrial septum are uncommon lesions that are often accompanied by other cardiac anomalies or systemic thrombosis. The authors report 1 case of atrial septum aneurysm that was diagnosed by two-dimensional contrast echocardiography. At surgery a membrane-like, fenestrated aneurysmal protrusion to the right atrium without thrombosis was seen. The atrial septum was closed without using an artificial patch after some of the aneurysm with fenestrations was resected.     

Popliteal venous aneurysm: case report

Popliteal vein aneurysms are rare but they have clinical relevance because of their propensity to cause thromboembolic complications. The widespread use of duplex scanning in the work-up of venous complaints will make their diagnosis increasingly frequent. Surgical therapy cures the disease with low morbidity. We present a typical case and review pertinent literature on the subject.     

Right atrial isomerism diagnosed by STIC-HD live flow and autopsy: A case report

Rationale:Right atrial isomerism (RAI) is one of the most severe forms of congenital heart disease. This case of RAI was so complex that it incorporated 7 heart defects. It can be challenging to display the spatial relationship between different anatomical structures using conventional two-dimensional and color ultrasound (2D-Doppler imaging); therefore, we used spatio-temporal image correlation (STIC) and high definition live flow imaging technology to vividly display this case of RAI in a stereoscopic mode.Patient concerns:A 24-year-old woman was referred to our tertiary center at 24 weeks of gestation. The woman had difficult conceiving. Once pregnant, she was opposed to abortion, even if there was a possibility of deformity.Diagnosis:The fetus presented with an atrioventricular septal defect, persistent left superior vena cava, supra-cardiac total anomalous pulmonary venous connection (TAPVC), double outlet right ventricle, right ductus arteriosus, right aortic arch (RAA) with mirror image branching, and aortic arch dysplasia.Interventions:After consulting a pediatric cardiologist, the woman requested an abortion and consented to an autopsy.Outcomes:Autopsy supported the echocardiographic findings.Lessons:Accurate diagnosis of RAI is essential for clinical and parent decision making. 2D-Doppler imaging combined with STIC-HD live flow can be used to visualize the spatial morphology of blood vessels, including the cardiac chambers and great vessels of the fetal heart, and smaller peripheral vessels.     

Left atrial appendage aneurysm: correlation of noninvasive with clinical and surgical findings: report of a case.

Congenital left atrial appendage aneurysm is rarely diagnosed on the basis of an abnormal cardiac silhouette. Patients with a left atrial appendage aneurysm often present with symptoms of systemic emboli or supraventricular arrhythmias. A patient with left atrial appendage aneurysm was diagnosed by correlation of two noninvasive techniques echocardiography and radionuclide scintiscanning. Angiography was confirmatory and aneurysmectomy was successfully performed.
