The aim of study was to reveal features of a current and diagnostics of ectopic atrial tachycardias (AT) and atrial fibrillation (AF) from the outfall of superior vena cava (SVC) and to estimate results of interventional treatment of these arrhythmias.
Methods and Results
From 2000 till 2017, 2857 patients were operated with AF (1950 males) and 495 patients with AT (225 males). Arrhythmogenic area in SVC was found in 9 patients with AF and in 7 patients with AT. The average age was 46.1 ± 19.1 years (from 20 till 72), 7 males. Paroxysmal AF was defined in 7 patients (44%), persistent AF in 2 patients (13%). Inefficient radiofrequency isolation of pulmonary vein (PVI) was earlier executed in 5 patients (31.3%). 26 procedures in total were done (1.63 in 1 patient). Repeated radiofrequency ablation of SVC was made in 1 patient (6.25%) with AT due to recurrence of arrhythmia.
Ectopic AT and AF from the area of SVC are rather rare, RF applications in this area associated with high efficacy and low rate of complications.
