We have analysed the atrioventricular junction, ventricular mass, and ventriculoarterial junction in 43 hearts with isomeric atrial chambers. Of the hearts, 32 had atrial chambers of bilateral right morphology while 11 had atrial chambers with bilateral left atrial characteristics. Among the hearts with right atrial isomerism, there were 13 biventricular hearts, all with ambiguous atrioventricu...

A case is reported of a 59 year old woman who presented with palpitations. Electrocardiographic studies revealed atrial fibrillation and atrioventricular block. Echocardiography and magnetic resonance imaging showed a right atrial cystic mass attached to the interatrial septum. The patient underwent surgical excision of the mass. Histopathological findings were of a cystic tumour of the atriove...

A 73-year-old woman who had undergone hysterectomy and radiotherapy 17 years previously for uterine leiomyosarcoma presented to the emergency department with newonset exertional shortness of breath of 4-days duration. On admission, she was dizzy and tachypneic at rest. Chest auscultation revealed an apical diastolic murmur, gallop, and bilateral rales, and bilateral pleural effusion and interst...

A70-year-old man with ischemic dilated cardiomyopathy and a known right atrial mass, presumed to be thrombus, presented to the hospital with 3 weeks of fevers and chills. One year before this admission, transesophageal echocardiography had demonstrated a 333-cm mass in the right atrium, extending into the superior vena cava (Figure, panel a). The mass was contiguous with the tip of a Groshong c...

We describe a neonate who presented with an echogenic mass in the right atrium 8 weeks after closure of ventricular and atrial septal defects. On a routine post operative check up after discharge, a mass was detected in the right atrium on echocardiography. As a thrombotic formation was suggested, lysis was started, in combination with the administration of unfractioned heparin. As there was no...

The formation of atrial hematomas with a mass effect in patients who have undergone cardiac surgery originates a clinical and hemodynamic syndrome that is difficult to assess. Hypotension with high right atrial pressure and equalization of pulmonary wedge pressure is not always present due to the irregular distribution of the hematoma in cardiac chambers. Transesophageal echocardiography is a u...

We report a patient with a mass in the right atrium which led to pulmonary embolism. Postoperatively the mass was identified as a tuberculoma and it was culture-positive for Mycobacterium tuberculosis. Patient responded to modified antitubercular treatment and discharged from hospital in satisfactory condition.

Background/Introduction This 62 year-old gentleman presented with increasing shortness of breath on exertion and reduced exercise tolerance (NYHA class III). Brain natriuretic peptide and D-dimer were markedly elevated. ECG showed no evidence of acute ischaemia. There was a history of gastro-oesophageal reflux disease and excessive alcohol consumption 8 years previously. He was an ex-smoker wit...
