Atrial anatomical variations on computed tomography angiography associated with atrial fibrillation and those predicting recurrence following pulmonary vein isolation.

ABSTRACT:

Background

We aim to investigate the atrial anatomical variations in patients with and without atrial fibrillation (AF) using cardiac-computed tomography angiography (CCTA) and identify features associated with AF recurrence following pulmonary vein isolation.

Materials and methods

We retrospectively reviewed 502 CCTAs of patients with AF performed prior to a pulmonary vein isolation procedure with 1058 CCTAs of patients without AF performed to rule out coronary artery disease between 2014 and 2017. Anatomical variations of both atria including left atrial diverticula (LAD), right atrial diverticula (RAD), Bachmann bundle shunt (BBS), and pulmonary vein anatomy were assessed.

Results

We found that patients with AF were older (67 ± 14 vs 63 ± 13 years, P = .039)
