[The superior vena cava as a site of ectopic foci in atrial fibrillation].
Radiofrequency catheter ablation of ectopic foci that trigger atrial fibrillation has been established as a curative method for patients with symptomatic paroxysmal atrial fibrillation. Although the majority of these foci are located in and around the pulmonary veins, other less common locations have been identified. Recognition that foci can lie outside the pulmonary veins is important for ens...
متن کاملSuperior Vena Cava Isolation In Ablation Of Atrial Fibrillation.
Superior vena cava (SVC) is one of the most important non-pulmonary vein (PV) origins of atrial fibrillation (AF). SVC isolation (SVCI) is effective especially in patients with paroxysmal AF from SVC origin. However, SVCI should be carefully performed because of potential complications such as phrenic nerve paralysis, SVC stenosis, and sinus node injury There are two major different approaches ...
متن کاملFibrillation in the superior vena cava mimicking atrial tachycardia.
A 49-year-old male was referred for catheter ablation for paroxysmal atrial fibrillation (PAF). PAF had recurred after each of 2 prior left atrial ablation procedures. He had a structurally normal heart with a left atrial diameter of 43 mm. The patient presented to the electrophysiology laboratory in AF with an average AF cycle length (CL) of 150 ms and reconnected pulmonary veins. After electr...
متن کاملAtrial fibrillation originating from persistent left superior vena cava.
BACKGROUND The left superior vena cava (LSVC) is the embryological precursor of the ligament of Marshall, which has been implicated in the initiation and maintenance of atrial fibrillation (AF). Rarely, the LSVC may persist and has been associated with some organized arrhythmias, though not with AF. We report 5 patients in whom the LSVC was a source of ectopy, initiating AF. METHODS AND RESUL...
متن کاملFocal Atrial Fibrillation from the Superior Vena Cava.
We report the case of a 66 year-old male who underwent catheter ablation for drug-refractory paroxysmal atrial fibrillation (AF) at our institution. Radiofrequency catheter ablation was performed using a three-dimensional electroanatomical mapping system. During ablation of the pulmonary veins (PV), right atrial ectopics were noted to repeatedly trigger AF and atrial tachycardia (AT). After PV ...
