“…The prevalence of LA out-pouching structures was slightly higher than previously reported prevalence values of accessory LA appendages and LA diverticula that were around 10%-46% [5-7,9,17]. The location of LA out-pouching structures was concordant with previous results where they were commonly seen in the right anterosuperior wall and left lateral wall of the LA although somewhat different classifications have been used to categorize the location of LA out-pouching structures in previous studies [5,8,9,16]. …”

“…In general, an accessory LA appendage was defined if the structure had a discernible ostium and irregular contours suggestive of the presence of pectinate muscles, and LA diverticulum was defined if the structure had a saclike shape with a broad-based ostium and a smooth contour at the body portion. However, the differentiation of an accessory LA appendage from LA diverticulum can be difficult because the defining features may be subtle and some cases may express features of both appendages and diverticula [5,16]. Thus we recorded these structures together as out-pouching structures.…”

Background and PurposeClinical significance of out-pouching structures of the left atrium (LA) as potential embolic sources remains unclear. We sought to evaluate the association between stroke and LA out-pouching structures.MethodsA case-control study was conducted to assess the prevalence of LA out-pouching structures in subjects with and without stroke. Case subjects were 270 stroke patients who had undergone cardiac CT. Control subjects were 270 age- and sex-matched patients without a history of stroke and who had undergone cardiac CT. Presence of LA out-pouching structures was determined by ECG-gated cardiac CT. The location of out-pouching structures was categorized as near Bachmann bundle, anterior, inferoseptal, inferior, and lateral. The prevalence, number and location of out-pouching structures and clinical characteristics were compared between the two groups.ResultsOne hundred sixty eight out-pouching structures were identified in 139 stroke patients (51%), while a total of 169 out-pouching structures were found in 155 control patients (57%) (p=0.1949). The prevalence of LA out-pouching structures with different locations was not significantly different between the stroke group and control group. In the stroke group, the prevalence of out-pouching structures was not significantly different by subtypes of ischemic stroke and the prevalence of LA out-pouching structures was not different between patients with atrial fibrillation (AF) and without AF.ConclusionThe left atrial out-pouching structures are commonly seen in a population with and without stroke with similar prevalence. Our study suggests that LA out-pouching structures are not significant risk factors of stroke.

“…Although the number of previous studies on left atrial diverticula is limited, the ability to perform cardiac imaging has been improved by MDCT (14,15). In contrast to earlier reports, the present results demonstrate a high frequency of atrial diverticula among the general population.…”

“…In addition, electrocardiographically-gated (ECG) multidetector CT (MDCT) scans have allowed for unprecedented three-dimensional spatial resolution for morphologic evaluation of the left atrium [3] [4]. As a result of constant enhancement in MDCT imaging, numerous previously undescribed left atrial anatomic abnormalities (LAAA) including accessory appendages, diverticula and septal pouches have been identified with remarkably high prevalence [3] [5]- [13].…”
