“…RA dysfunction may cause POAF development with mechanisms similar to LA dysfunction because they share the same embryonic origin and cellular structure. 9,22,27,28 During the evaluation of the RA by deformation analyses, conduit, reservoir, and contraction functions can be calculated. RASr is the most commonly studied of these functions.…”

Purpose Atrial fibrillation (AF) is relatively frequent in the postoperative period, and is associated with an increased frequency of adverse events. The role of right atrial (RA) volume and functions in the development of AF is unknown. In this study, we investigated the effect of RA echocardiographic indices on AF development in the postoperative period. Method We enrolled 142 consecutive patients who underwent coronary artery bypass surgery, and assigned them into two groups depending on the occurrence or not of AF development in the postoperative period. Results A propensity score matching analysis was performed to balance the groups, and 37 pairs were eventually included in the analysis. The median age was 67.5 (63‐75) years and 73.3% of them were males. In the univariate analysis, right atrial volume index (RAVi), right atrial strain during reservoir phase (RASr), left ventricular global longitudinal strain, right ventricular strain, left atrial volume index, left atrial strain during reservoir phase, and systolic pulmonary artery pressure were associated with AF development. In the regression analysis, we found that RAVi (OR: 3.1, 95% CI: 2.2‐6.3, P: .033) and RASr (OR: 0.82, 95% CI: 0.67‐0.93, P: .048) were independent predictors of AF development. Conclusions RA structure and functions are closely associated with AF development in the postoperative period, and screening of RA functions prior to surgery may be useful for preventing AF development.

“…The concept of the “atrial function index” was originally proposed in 2002 by Thomaset et al [44] in patients with left-sided systolic heart failure and is calculated as a ratio, including analogs of left atrial reservoir function and size, as well as cardiac output. Following the left heart failure paradigm, Sophia et al [45] explored the prognostic significance of the RA function index (RAFi). RAFi was calculated as (RA emptying fraction × right ventricular outflow tract velocity-time integral)/(RA end-systolic volume index) (as shown in Fig.…”

“…RA size, as an indirect measure of RV function, has also proven to be relevant to the prognosis, and in a recent meta-analysis the risk of all-cause mortality increased by 50% for every 5-unit increase in RA area [81]. In addition, metrics of RA function-such as the RA function index (RAFi) and the RA peak longitudinal strain-have been shown to strongly predict clinical failure in precapillary PH [82,83].…”

Pulmonary arterial hypertension (PAH) is characterized by an insult in the pulmonary vasculature, with subsequent right ventricular (RV) adaptation to the increased afterload that ultimately leads to RV failure. The awareness of the importance of RV function in PAH has increased considerably because right heart failure is the predominant cause of death in PAH patients. Given its wide availability and reduced cost, echocardiography is of paramount importance in the evaluation of the right heart in PAH. Several echocardiographic parameters have been shown to have prognostic implications in PAH; however, the role of echocardiography in the risk assessment of the PAH patient is limited under the current guidelines. This review discusses the echocardiographic evaluation of the RV in PAH and during therapy, and its prognostic implications, as well as the potential significant role of repeated echocardiographic assessment in the follow-up of patients with PAH.
