Introduction Focal atrial tachycardias (ATs) can arise from several different anatomic regions both in the right atrium (RA) and left atrium (LA). The prevalence of focal atrial tachycardia is not well known. A European study of young males applying for pilot licenses demonstrated that 0.34% had asymptomatic atrial tachycardia and 0.46% had symptomatic atrial tachycardia1. It is well-recognized that these foci do not occur randomly throughout the atria but tend to cluster at characteristic anatomic locations. However, the distribution of these sites in the total amount of ATs is not well recognized. Purpose The objective of this study was to determine the prevalence of different anatomic locations of ATs in the electrophysiology lab of a single large center (300 ablations per year) and to verify the site of ablation. Methods We collected 150 consecutive patients submitted to catheter ablation of ATs between January 2010 to December 2020. Anatomic localization of the atrial focus was performed during tachicardia by analysis of endocardial activation sequence. Results The distribution of the different anatomic locations is rappresented in the figure. In 134 patients (89%) ATs were localized in the RA. In the RA, these foci mainly occured along the crista terminalis (32%), the perinodal region (22,6%), the anterior right sided septum, near the foramen ovale (9,3%), the posterior right-sided septum (8%), the ostium of the coronary sinus (5,3%), the tricuspid annulus (5,3%), the superior vena cava (4,6%), the infero-lateral wall (2,5%), the right atrial appendage (0,6%) and the cavotricuspid histhmus (0,6%). In the LA (11%), foci occur predominantly at the pulmonary vein ostia (5,2%) and less commonly at the mitral annulus (2,5%), the left sided septum (0,6%), the appendage ridge (0,6%), the roof (0,6%) and the anterior wall (0,6%). For each location of AT, the ablation was performed at the earliest activation site, but about the perinodal ATs, the ... |
