Arrhythmogenic left atrial roof vein
نویسندگان
چکیده
A seventy year-old male was referred to our hospital to undergo radiofrequency catheter ablation (RFCA) for drug-refractory paroxysmal atrial fibrillation (AF). Pre-operative three-dimensional computed tomography revealed a unique left atrial (LA) roof vein. Electrophysiological findings showed expansion of the myocardial sleeve and local firing in the LA roof vein. We performed isolation of this arrhythmogenic abnormal vein concomitant with general pulmonary vein isolation in this case, and AF did not recur after the procedure.

متن کاملArrhythmogenicity of the Coronary Sinus
The coronary sinus (CS) is the cardiac venous system that begins at its ostium in the right atrium and ends at the origin of the great cardiac vein.1,2,3 The major tributaries of the CS include the great cardiac vein (anterior cardiac vein), the left obtuse marginal vein, the posterior (or inferior) left ventricular vein, the middle cardiac vein, and the right coronary vein. In addition, atrial...

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...

A 60-year-old man with arrhythmogenic right ventricular dysplasia, dilated right heart chambers, moderate tricuspid regurgitation, and mild pulmonary hypertension (systolic pulmonary pressure of 45 mm Hg) underwent pulmonary vein isolation (PVI) under general anesthesia due to symptomatic atrial fibrillation. Using a single transseptal puncture–double transseptal approach, a 12-F FlexCath Advan...
متن کاملRupture of the left atrial roof due to blunt trauma.
Cardiac rupture after blunt trauma is rare and associated with high mortality. The anatomic pattern of blunt cardiac rupture has been demonstrated with the right cardiac chambers more frequently affected than the left. Furthermore, left atrial injury is usually restricted to the atrial appendage and the pulmonary vein-atrial junction. Herein, we report the first case of a 61-year old man with a...
