“…Previous reports regarding accessory LA appendages or diverticula suggested that these out-pouching structures might be associated with an increased risk of thromboembolic disease because of low flow and turbulence within the sac-like structure [5,16]. There have been a few case reports about the aggressive treatment of these out-pouching structures that were regarded as a potential cardioembolic source [10,18,19]. We hypothesized that if the LA out-pouching structures were a possible embolic source, the prevalence of these structures would be higher in patients who were classified as stroke with undetermined etiology than in others that were differently classified.…”

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.

“…With the application of dual-source CT, small left atrial diverticula are detected as common anatomic structures with a prevalence of more than 30% [3]. There have been isolated reports of very large left atrial diverticula that extend to the apex of the heart over the ventricular surface [1,2,4,5]. To our knowledge, this is one of the largest left atrial diverticula to be reported.…”

“…Giant left atrial diverticula are usually diagnosed in childhood because of the appearance of symptoms [1,2] and have even been detected using prenatal fetal echocardiography [4]. Diagnosis can be delayed until adulthood when a patient has only the nonspecific symptom of chest tightness without the other characteristic symptoms of concomitant atrial fibrillation, left atrial thrombus, mitral regurgitation, or other cardiac malformations.…”

“…Diverticula commonly manifest with mitral regurgitation, atrial fibrillation, thromboembolism, or compression of the surrounding structures [1][2][3]. Giant left atrial diverticula are mostly diagnosed in childhood [1,2]. Here, we present a case of giant left atrial diverticulum in an adult who presented with chest tightness and ultimately underwent diverticulum resection.…”

“…While aneurysms of the atrial septum are frequently observed, atrial diverticula especially those of the left atrium represent a rare malformation. Only a limited number of cases has been reported in the literature 2–4 . Both identities are distinguished by their wall structure and motion.…”

Diverticula of the left atrium are very rare malformations of unknown etiology and may be associated with arrhythmias, thromboembolism, or mitral valve regurgitation. We report a patient with suspected coronary artery disease (CAD) in whom we performed a low-dose computed tomography coronary angiography using prospective electrocardiogram triggering. CAD could be ruled out. Incidentally, we found a diverticulum on the posterior wall of the left atrium combined with an interatrial septal aneurysm. The diagnosis was confirmed by transthoracic echocardiography.
