“…Although previous studies have identified variable locations, the most commonly reported location of left atrial diverticula is the anterior superior part of the left atrium. The least common location is the posterior wall ( 8 ). They are generally asymptomatic; however, they can be associated with arrhythmias, thromboembolism, and mitral valve regurgitation ( 9 ).…”

Cardiac computed tomography (CT) is most commonly performed for the evaluation of the coronary arteries; however, non-coronary cardiac pathologies are frequently detected on these scans. In cases where magnetic resonance imaging cannot be used, cardiac CT can serve as the first-line imaging modality to evaluate many non-coronary cardiac pathologies. In this article, we discuss congenital non-coronary abnormalities of the left heart and their cardiac CT imaging features.

“…Left atrial diverticula are thought to represent remnants of the cardinal venous system (stump or failure of regression) during embryologic development [9]. The prevalence of left atrial diverticulum has been reported to vary between 10 and 46% in the literature [2, 3, 10]. Hołda et al reported the presence of LAD as 18% in their study, which examined heart anatomy in 200 autopsied, non-atrial fibrillation hearts [11].…”

Introduction Catheter ablation (CA) for atrial fibrillation (AF) has been a major cornerstone in the management of AF. Despite promising advances in CA techniques, long-term results reveal a high rate of recurrence after the procedure. Left atrial diverticulum (LAD), a common anatomic variant of the left atrium, was previously shown to be associated with increased risk of thrombus formation, cardiac perforation and arrhythmia. In this study we aimed to investigate the relationship between LAD and recurrence in patients undergoing CA for AF. Material and methods A total of 100 consecutive patients with a mean age of 53 ±12.1 years (53% male) underwent radiofrequency (RF) (46, 46%) or cryoballoon (54, 54%) catheter ablation for atrial fibrillation preceded by cardiac computed tomography (CT) imaging. Clinical and procedural characteristics of the patients with and without AF recurrence were compared. Results Twenty-three (23%) patients had AF recurrence and 77 (77%) patients had no recurrence. The clinical parameters such as hypertension, diabetes mellitus, coronary artery disease and stroke did not differ between the groups. Left atrium diameter was significantly different between the two groups (4.1 ±0.5 vs. 3.9 ±0.5, p = 0.042). Presence of LAD was not different between the two groups (7 (31.8) vs. 21 (28.8); p = 0.794). Multivariate logistic regression analysis revealed RF ablation as the most important independent variable for AF recurrence (β = 3.115, p < 0.001, OR = 22.526, 95% CI: 4.287–118.351). Conclusions The presence of left atrial diverticulum is not associated with recurrence in patients undergoing RF and cryoballoon CA for atrial fibrillation.

“…Accessory LA appendages represent less common abnormalities with prevalence between 3 and 10% of subjects undergoing cardiac CT. LA accessory appendages are defined as sac-like structures with irregular contours that resemble the pectinate muscle and have narrower ostia than diverticula [ 68 ]. They are congenital and carry potential risk for thromboembolic events.…”

In the last decade, there has been increasing evidence that comprehensive evaluation of the left atrium is of utmost importance. Numerous studies have clearly demonstrated the prognostic value of left atrial volume for long-term outcome. Furthermore, advances in catheter ablation procedures used for the treatment of drug-refractory atrial fibrillation require the need for detailed knowledge of left atrial and pulmonary venous morphology as well of atrial wall characteristics. This review article discusses the role of cardiac magnetic resonance and computed tomography in assessment of left atrial size, its normal and abnormal morphology, and function. Special interest is paid to the utility of these rapidly involving noninvasive imaging methods before and after atrial fibrillation ablation.
