background: there is some evidence indicating improvement in myocardial performance after atrial septal defect closure, either device closure or surgical, but ventricular dyssynchrony has not been evaluated before and after surgical closure. the aim of this study was to evaluate ventricular mechanical dyssynchrony in patients with atrial septal defect before and after surgical closure. methods:...

A 27-year-old man with primary oxalosis and extensive visceral involvement was maintained on long-term chronic hemodialysis. He had an episode of presyncope associated with electrocardiographic findings of an erratic atrial rhythm, atrioventricular dissociation due to an accelerated junctional rhythm and right bundle branch block. Electrophysiologic studies showed irregular atrial depolarizatio...

the presence of tumor thrombus in the right atrium is frequently the result of direct intraluminal extension of infra-diaphragmatic malignancy into the inferior vena cava (ivc) or supradiaphragmatic carcinoma into the superior vena cava (svc). right atrial tumor thrombus with extension into both svc and ivc has not been reported in the literature. we present a patient who presented with symptom...

BACKGROUND Parachute tricuspid valve is a rare congenital malformations explained in the literature. In most cases, this malformation coexists with other congenital defects. The importance of this condition depends on its functional consequences. CASE REPORT First case was a 52-year-old female patient presented with palpitation. She had a history of paroxysmal supraventricular tachycardia. Tr...

conclusions the authors emphasize on the rarity of this pathology among children, its clinical polymorphism, the necessity of a rapid diagnosis, and an appropriate treatment to avoid complications and recurrence of the tumor. introduction right atrial myxoma is a rare disease among children and its clinical presentation is not specific. case presentation we reported a four-year-old girl with ex...

BACKGROUND The size of right atrium is expected to be different in diverse healthy ethnic groups. It is important to know the normal size of right atrium in our healthy population. OBJECTIVE The study aimed to find out the normal values of right atrial volume, right atrial short axis diameter and right atrial long axis diameter in healthy Nepalese population with normal echocardiographic find...

A 46-year-old man was admitted to the hospital with anorexia, fever and weight loss. Thoracic computed tomography revealed a right upper lobe mass infiltrating the right atrium (Picture). Bronchoscopy and a biopsy confirmed pleomorphic carcinoma of the lung. The patient received chemoradiotherapy and succumbed to the disease eight months after the initiation of the therapy. Cardiac involvement ...

PHACES syndrome (Posterior Fossa Malformations, Hemangioma, Arterial Anomalies, Cardiac Defects and Coarctation of the Aorta, Eye Abnormalities, and Sternal Abnormalities or Ventral Developmental Defects) is a rare neurocutaneous syndrome, which characteristic feature is large segmental hemangioma. Extracutaneous involvement is an important cause of morbidity in this syndrome.<br /...
