Abstract

AIM: The relationship between left atrial appendage (LAA) diameter and length and CHADS2 and CHADS2-Vasc scores has not been established yet. We sought to examine this relationship in atrial fibrillation (AF) patients undergoing catheter ablation.
Methods: Sixty patients who were to undergo catheter ablation for AF were examined with computerized tomography and their LAA diameter and lengths were measured via Cartomerge system (Figure 1).
Results: Of 60 patients, the mean age was 54,83±13,17 years and 48,3%(29) of them were female. Hypertension was present in 46%(28) patients. Diabetes mellitus was present in 10%(6) patient and there was no heart failure patient in our study group. Mean CHADS2-VASc score was 1,42±1,293. Mean LAA length and diameter was 52±9,252mm and 21±6,543mm respectively. By Spearman’s correlation test, there was a significant correlation between LAA diameter and CHADS2-VASc score in our study group (r:0.286, p:0.027).
Conclusions: CHADS2-VASc score was found to be positively correlated with LAA diameter in patients with AF.
