Electrophysiological breakthroughs from the left atrium to the pulmonary veins.
BACKGROUND The extent of ostial ablation necessary to electrically disconnect the pulmonary vein (PV) myocardial extensions that initiate atrial fibrillation from the left atrium has not been determined. METHODS AND RESULTS Seventy patients underwent PV mapping with a circumferential 10-electrode catheter during sinus rhythm or left atrial pacing. After assessment of perimetric distribution a...
متن کاملPulmonary Metastatic Leiomyosarcoma with Left Atrial Extension via the Pulmonary Vein Manifests as Acute Pulmonary Edema
We report a case who presented to our emergency department with symptoms of congestive heart failure and acute pulmonary edema. The transthoracic echocardiography demonstrated a large tumor that occupied two-thirds of the left atrium and impeded the mitral valve flow. The patient underwent cardiac surgery with removal of the LA tumor that was intraoperatively found extending through the right i...
متن کاملAnatomic characteristics of left atrium and openings of pulmonary veins.
OBJECTIVE Left atrium (LA) and left atrial pulmonary venous anatomy have clinical importance for atrial fibrillation (AF) and cardiac tumor surgery. A detailed anatomic knowledge of these structures may faciliate clinical evaluations. The aim of this study was to assess LA size and to demonstrate other anatomic features of LA with pulmonary vein openings in normal population. METHODS This des...
متن کاملMorphofunctional study of the junction between the left atrium and the pulmonary veins in patient with pulmonary hypertension.
OBJECTIVE To study the arrangement of the myocardial fiber bundles at the pulmonary venous left atrial junction in patients with pulmonary hypertension, and to discuss the pathophysiological importance of this element in the etiology of acute pulmonary edema. METHODS We obtained 12 hearts and their pulmonary vein extremities from postmortem examinations of patients with the anatomicopathologi...
متن کاملTotal drainage of pulmonary veins into the right atrium.
Anomalies of the pulmonary venous return are uncommon, particularly malformations with total drainage of the pulmonary veins directly into the right atrium. Brody (1942) reviewed the literature on anomalous pulmonary venous drainage, dealing with 106 cases, including four personal ones. Further necropsy reports have since been presented by Vass and Mack (1949) and Smith (1951), the latter also ...
