INTRODUCTION Atrial fibrillation was previously reported in patients with esophageal cancer as a complication of total esophagectomy or photodynamic therapy. Here, we propose that atrial fibrillation may also be caused by external compression of the left atrium by esophageal cancer. CASE PRESENTATION We present a 58-year-old man who developed atrial fibrillation with rapid ventricular rate in...

Recent decades have seen rapid developments in arrhythmia treatment, especially the use of catheter ablation. Although the substrates of atrial fibrillation, its initiation and maintenance, remain to be fully elucidated, catheter ablation in the left atrium has become a therapeutic option for patients with this arrhythmia. With ablation techniques, various isolation lines and focal targets are ...

Abnormal connection of the right superior caval vein to the left atrium is an uncommon systemic vein drainage anomaly, with only a few cases reported among congenital heart disease (CHD), around 20 cases published in the medical literature. The inferior vena cava connection with the left atrium, also very rare, can appear directly or in heterotaxy. Clinical suspicion arises due to the presence ...

BACKGROUND Several percutaneous circulatory support systems have been recently introduced into clinical practice for the treatment of cardiogenic shock or refractory nontolerated ventricular tachycardia, in support of high-risk catheter interventions and, occasionally, cardiopulmonary resuscitation. To date, however, a direct comparison of the available systems has not been performed. METHODS...

cor triatriatum is defined as a membrane within the left atrium, which might lead to restricted pulmonary venous return. diagnosis is usually achieved by echocardiography in early infancy. therapy of choice is the excision of the membrane. herein, successful correction of cor triatriatum in a 4-year-old girl is presented, and the clinical features, echocardiographic findings, and the surgical t...

OBJECTIVE To determine the type of atrial fibrillation induced by use of 2 pacing protocols during fentanyl and pentobarbital anesthesia before and after administration of atropine and to determine the organization of electrical activity in the left and right atria during atrial fibrillation in German Shepherd Dogs. ANIMALS 7 German Shepherd Dogs. PROCEDURES Extrastimulus and pacedown proto...

= Abstract =An autopsy case is described of a premature closure of the foramen ovale with a marked dilatation of the left atrium and an intact ventricular septum with aortic atresia but without left ventricular hypoplasia. This 28-week-old male baby was a stillborn to a 34-year-old multiparous mother. An intrauterine sonogram revealed marked ascites with anasarca, an enlarged left atrium and ve...

A 77-year-old man with a history of renal cell carcinoma presented with orthostatic syncope. Investigation revealed metastatic carcinoma in the left lung extending through the pulmonary veins into the left atrium obstructing the mitral orifice. On review of the literature, this case appears to be the first to describe metastatic carcinoma to the left atrium presenting as a primary cause of sync...
