“…Spearman rank correlation coefficient showed that there is a relationship between LAVI and LVEF, that is consistent with the research data on the contribution of LA to LV function [33,34]. According to our study, only LAVI > 34 ml/m 2 is a risk factor for arrhythmia after TSA (Table 4).…”

“…The findings confirm that LA remodeling and volume expansion reduces the effectiveness of TSA. It is possible that the presence of excess fibrous tissue (more than 20-30%) in the left and right atrium, as well as the presence of epicardial fat in the left atrium, affect the effectiveness of TSA [20,29,33,34]. We will present the results of research in this area in subsequent publications.…”

Research objective: establish the impact of Left Atrium Volume Index (LAVI) on on effectiveness of Thoracoscopic Ablation (TSA) in the Treatment of Atrial Fibrillation (AF) and define the risk factors for manifestation of supraventricular arrhythmias in the long-term follow-up resultsMethods. Prospective cohort study of 121 patients with AF (from 2018 to 2021) who performed TSA. The patients were divided into two groups: patients with increased LAVI (group I), patients with normal LAVI less than 34 ml/m2 (group II).Results. According to echocardiography, the mean LAVI was 45.48 ± 9.3 ml/m2 and 28.59 ± 4.13 ml/m2 in groups I and II, respectively (p = 0.012). The mean value of left ventricular ejection fraction (LVEF) according to Teicholz in group I was 61.62 ± 7.041%, in group II 63.57 ± 6.16% (p = 0.8). Spearman's сorrelation analysis showed the relation-ship between LAVI and LVEF before surgery and in the long-term follow-up period, that is agreed with world literature data about contribution left atrial (LA) to left ventricular (LV) function. According to our study, only LAVI < 34 ml/m2 is a risk factor for arrhythmia after TSA. Effectiveness TSA in I group was 77.8%, that is lower than the II group – 88.9%. 3 months after TSA, 20 (17%) patients were required catheter ablations (CA), mainly in I group.Conclusions. Research results showed that an increase in LAVI significantly reduces the effectiveness of TSA in the long-term period by 11.1% compared with LAVI < 34 ml/m2. That are conform with other data of previously submitted works.

“…In CMR, the development of artificial intelligence techniques has reduced analysis time significantly, but this is not yet available for most atrial analysis techniques. Atrial strain, which is one of the most studied techniques in recent times and has also been included in imaging guidelines (86), is still limited due to measurement variability due to imaging modality, software, and operator factors (87).…”

Changes in atrial size and function have historically been considered a surrogate marker of ventricular dysfunction. However, it is now recognized that atrial cardiomyopathy (ACM) may also occur as a primary myocardial disorder. Emerging evidence that ACM is a major risk factor for atrial fibrillation, heart failure, and thromboembolic stroke, has highlighted the significance of this disorder and the need for better assessment of atrial metrics in clinical practice. Key barriers in this regard include a lack of standardized criteria or hierarchy for the diagnosis of ACM and lack of consensus for the most accurate phenotyping methods. In this article we review existing literature on ACM, with a focus on current and future non-invasive imaging methods for detecting abnormalities of atrial structure and function. We discuss the relative advantages and disadvantages of transthoracic echocardiography and cardiac magnetic resonance imaging for assessing a range of parameters, including atrial size and contractile function, strain, tissue characteristics, and epicardial adipose tissue. We will also present the potential application of novel imaging methods such as sphericity index and four- or five-dimensional flow.

“…The former can be calculated with 2D or 3D techniques from the atrial volumes in the different phases and the latter by speckle tracking or tissue Doppler imaging ( Figure 3 and Figure 4 ). The formulae for the calculation of the three atrial volumetric phases are included in Table 1 [ 23 , 24 , 25 , 26 , 28 ]. However, given the great variability of these parameters between individuals and pathologies, they are rarely used in clinical practice and are mainly applied in research studies [ 29 ].…”

The left atrium (LA) plays a vital role in maintaining normal cardiac function. Many cardiac diseases involve the functioning of the LA directly or indirectly. For this reason, the study of the LA has become a priority for today’s imaging techniques. Assessment of LA size, function and wall characteristics is routinely performed in cardiac imaging laboratories when a patient undergoes transthoracic echocardiography. However, in cases when the LA is the focus of disease management, such as in atrial fibrillation or left atrial appendage closure, the use of multimodality is critical. Knowledge of the usefulness of each cardiac imaging technique for the study of LA in these patients is crucial in order to choose the most appropriate treatment. While echocardiography is the most widely performed technique for its evaluation and the study of wall deformation analysis is increasingly becoming more reliable, multidetector computed tomography allows a detailed analysis of its anatomy to be carried out in 3D reconstructions that help in the approach to interventional treatments. In addition, the evaluation of the wall by cardiac magnetic resonance imaging or the generation of electroanatomical maps in the electrophysiology room have become essential tools in the treatment of multiple atrial pathologies. For this reason, the goal of this review article is to describe the basic anatomical and functional information of the LA as well as their study employing the main imaging techniques currently available, so that practitioners specializing in cardiac imaging techniques can use these tools in an accurate and clinically useful manner.
