“…The left atrial diverticulum typically has a sac‐like, smooth body with a broad‐based ostium. The aLAA can be identified by its ostium associated with a visible neck, and body with irregular contours that are continuous with the pectinate muscles (Abbara et al, 2009; Balli et al, 2012; Duerinckx & Vanovermeire, 2008; Hoey et al, 2011; Incedayi et al, 2012; Ko et al, 2013; Lazoura et al, 2012; Patel et al, 2013). These differences can be visualized when using multidetector computed tomography (MDCT), the main method of their study.…”

Left atrial (LA) structures, including the accessory left atrial appendage (aLAA) and left atrial diverticulum, have been studied based on their prevalence, shape, and association with arrhythmia and thrombi formation. A pooled prevalence with morphometric data has not been determined in previous research. Our goal is to provide structured, clinically relevant information on said structures for clinical practitioners to use in their daily work. We propose that morphometric data of additional LA structures is necessary when considering the possible complications during cardiac interventions. We conducted a meta‐analysis of all relevant studies which used electrocardiogram (ECG)‐gated computed tomography (CT) imaging to determine the prevalence of LA structures and record their morphometric characteristics as well as the presence of thrombi. Data were extracted from 19 studies (n = 6643 hearts). The pooled prevalence estimate of left atrial diverticulum and/or aLAAs were reported from 14 studies and was 28.8%. The most common location noted was anterosuperior in the LA with 70.2% of structures found there. Data regarding thrombi presence in left atrial diverticulums or aLAAs were extracted from 11 studies and a thrombus was present in 0.2%. The prevalence rates of aLAAs and left atrial diverticulums are essential in performing uncomplicated cardiac interventions and reducing risk of electrophysiological procedures. Our findings show a considerable prevalence of LA structures in varying populations, provides information regarding the general characteristics of said structures, and does not support the previously theorized associated risk of thrombus formation in relation to LA structure presence.

“…Aneurysms are most commonly found in the right coronary artery (RCA, 40%), followed by the left anterior descending (LAD, 32%) and circumflex (LCX, 23%) coronary artery [36]. Aneurysms have traditionally been diagnosed by echocardiography (ECHO) or catheter angiography, but the latter may underestimate the size of the aneurysm if there is considerable intraluminal thrombus [37]. Nowadays, they are increasingly found on CT and MR imaging [35].…”

ObjectiveIncidental cardiac findings are often found on chest CT studies, some of which may be clinically significant. The objective of this pictorial review is to illustrate and describe the appearances and management of the most frequently encountered significant cardiac findings on non-electrocardiographically gated thoracic CT. Most radiologists will interpret multidetector chest CT and should be aware of the imaging appearances, significance, and the appropriate next management steps, when incidental significant cardiac disease is encountered on thoracic CT.ConclusionThis article reviews significant incidental cardiac findings which may be encountered on chest CT studies. After completing this review, the reader should not only be familiar with recognizing clinically significant cardiac findings seen on thoracic CT examinations but also have the confidence to direct their further management.
