Abstract
Abstract
Background
Strain rate reflects the rate of change of the distance between two points of the myocardium occurring in the cardiac cycle. It is a time-dependent parameter requiring higher temporal resolution than standard strain assessment. Because of this limitation, speckle tracking-derived left atrial (LA) strain rate analysis is of less interest in the literature.
Purpose
To analyze the prognostic value of LA strain rate during 2-years follow-up in patients with atrial fibrillation (AF).
Methods
The prospective study involved 80 patients with nonvalvular AF scheduled for elective electrical cardioversion (mean age 63.5±13 years, 60% male). All patients underwent echo before cardioversion and 24 hours after conversion to sinus rhythm. We analyzed standard echocardiographic parameters. Using the speckle-tracking method, we assessed LA strain rate during ventricular systole LA-SSR, in the early stage of ventricular diastole LA-ESR, and during atrial active pump phase LA-ASR. The last one is possible to measure only in the sinus rhythm. The analysis included 4-chamber and 2-chamber views. The clinical endpoint was predefined as AF recurrence.
Results
Median time of the current AF episode was 2.1 (IQR 0.5–5) months. Standard echo measurements revealed a median left ventricular ejection fraction of 55% (IQR 46–58) and the median of LA volume indexed to body surface area 42 ml/m2 (IQR 33–51). The successful cardioversion rate was 90%. During follow-up, we noticed AF recurrence in 49 (68%) patients. The median time-to-event was 2 (IQR 1 to 6.9) months. Receiver operating characteristic curve analysis revealed that LA-SSR <−0.73 s–1 (AUC=0.745; p=0.0004) and LA-ESR >−1 s–1 (AUC=0.703; p=0.0015) assessed during AF as well as LA-ESR >−0.88 s–1 (AUC=0.644; p=0.04) and LA-ASR >−1 s–1 (AUC=0.837; p<0.0001) measured in sinus rhythm were the optimal cut-off values for predicting AF recurrence. The figure presents Kaplan-Meier survival analysis for AF recurrence.
Conclusions
Speckle tracking-derived LA strain rate predicts the recurrence of AF after successful electrical cardioversion.

Abstract
Abstract
Background
Atrial fibrillation and flutter (AF/AFl) increase the risk of thromboembolic events by promoting clot formation in the left atrium (LA), which can be visualised using transoesophageal echocardiography (TEE). Current guidelines recommend initiation of oral anticoagulation (OAC) in patients with AF/AFl based solely on CHA2DS2VASc score (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, history of stroke or thromboembolism, vascular disease, age 65 to 74 years, female sex). Yet, some patients develop left LA thrombus (LAT) and experience thromboembolic events despite OAC.
Purpose
We sought to develop and externally validate a machine learning model for prediction of presence of LAT based on clinical, laboratory and transthoracic echocardiography (TTE) features.
Methods
We analyzed data from the multicenter, prospective LATTEE registry (Left Atrial Thrombus on Transesophageal Echocardiography) that included patients from 13 sites who underwent TEE before cardioversion or ablation between November 2018 and March 2021. We used XgBoost model to predict presence of LAT in TEE based on 29 clinical features, 10 biomarkers and 5 TTE measurements. We trained and tested the model internally using 10-fold hold-out cross validation and data from 12 sites (N=2489). We then tested the final model externally using data from the 13th site (that had recruited most patients, N=400). We compared the predictive performance with that of CHA2DS2VASc score using areas under receiver operating curve (AUC) and DeLong test.
Results
In the training and internal testing cohort the median age was 67 (Inter Quartile Range [IQR] 59, 74), 63% were male, 85% received OAC and LAT was found in 8.4%. Ablation was the indication for TEE in 43%, cardioversion in 57%. In internal, 10-fold hold-out cross validation, the model achieved AUC of 0.755 (95% confidence interval [CI]: 0.722, 0.788) while CHA2DS2VASc performed significantly worse with AUC of 0.638 (95% CI: 0.604, 0.673), P<0.0001 (Figure 1). Left ventricular ejection fraction, rhythm at the time of study (AF/AFl or sinus rhythm) and age received the highest feature importance ranking (Figure 2).
In the external testing cohort the median age was 67 (IQR 59, 74), 66% were male, 88% received OAC, ablation was the indication for TEE in 49% of cases and LAT was found in 6.8%. In this external cohort, our model achieved AUC of 0.815 (95% CI: 0.741, 0.889) while CHA2DS2VASc performed significantly worse with AUC of 0.684 (95% CI: 0.583, 0.785), P=0.028.
Conclusion
Machine learning based on readily available clinical data allows accurate prediction of the presence of LAT in patients with AF/AFl irrespective of OAC treatment. Such score could be used to identify patients who should undergo TEE before ablation or cardioversion. Subsequent studies to clinically evaluate such application of our model as well as how the model can predict future thromboembolic events are warranted.

Abstract
Introduction In COVID-19 patients, both preexisting cardiovascular disease as well as cardiac injury resulting from SARS-CoV-2 infection are associated with increased mortality. We hypothesized that novel parameters of myocardial function may be useful in the assessment of in-hospital and long-term prognosis. Aim The aim of study was to determine the prevalence of myocardial dysfunction revealed by speckle tracking echocardiography and its association with in-hospital and one-year mortality. Methods The study group comprised 192 patients hospitalized in the cardiology department due to COVID-19. All patients underwent transthoracic echocardiographic examination with off-line analysis. Using speckle tracking technique, we measured the following parameters: left ventricular global longitudinal strain (GLS), right ventricular global longitudinal strain (RV-GLS), right ventricular free wall strain (RV-FWS) and myocardial work parameters – global work index (GWI), global wasted work (GWW), global constructive work (GCW) and global work efficiency (GWE). The primary outcome was in-hospital and one-year mortality. Results 112 patients (mean age 68±14 years, 76 (68%) male) had adequate image quality to evaluate strain-derived parameters. 27 patients died during hospitalization and 44 patients died within one-year after discharge. In-hospital non-survivors were older, had lower baseline oxygen saturation (SpO2) and had higher NTproBNP (Table 1). In non-survivors speckle-tracking echocardiography revealed significant impairment of left and right ventricular function compared to the group of survivors (Table 1). The independent predictors of in-hospital death were GWE (OR 0.85; 95% CI 0.78–0.93) and SpO2 on admission (OR 0.91; 95% CI 0.86–0.96). Based on the ROC curve analysis, the optimal cut-off points for predicting in-hospital death were identified: GWE ≤87% (sensitivity 63%, specificity 89%) and baseline SpO2 value ≤88% (sensitivity 81%, specificity 71%). The independent predictors of one-year mortality were: age (OR 1.28 [1.13–1.46]), NTproBNP (OR 1.002 [1.001–1.003]), baseline SpO2 (OR 0.71 [0.59–0.86]) and RV-GLS (OR 1.32 [1.12–1.55]). Based on the ROC curve analysis, the cut-off points optimal for predicting death within 12 months after COVID-19 were also identified: baseline SpO2 value ≤88% (sensitivity 69.8%, specificity 77.3%), age >60 years (sensitivity 90%, specificity 43%), NTproBNP >500 pg/ml (sensitivity 95%, specificity 41.8%), RV-GLS >−18.5 (sensitivity 93%, specificity 64.2%). Conclusions Two-dimensional speckle tracking echocardiography is a useful technique to evaluate myocardial function in COVID-19 patients and provides good prognostic value for identifying patients at risk of death during hospitalization and in long term follow-up.

Background
The successful electrical cardioversion (EC) in patients with atrial fibrillation (AF) improves cardiac mechanical function and enables early assessment of atrial activity by echocardiography.
Purpose
To analyze conventional and novel parameters characterizing left atrium (LA) within 24 hours after the restoration of sinus rhythm (SR) and their prognostic value during 2-years follow-up.
Methods
Prospective study involved 71 patients with nonvalvular AF (mean age 64 ± 13 years, 61% male). All patients underwent echo 24 hours after conversion to SR. In addition, standard echocardiographic and Doppler parameters were assessed. Using speckle-tracking method we analysed LA longitudinal strain in reservoir and contractile phase. The clinical endpoint was predefined as AF recurrence.
Results
During a 24-months follow-up we noticed AF recurrence in 48 (68%) patients. The median time-to-event was 2.4 months (IQR 1 to 6.9). Standard echo measurements revealed a median of LV ejection fraction 55% (IQR 45-58) and median of LA volume indexed to body surface area 42 ml/m2 (IQR 34-51). Median mitral A wave was 0.46 m/s (IQR 0.39-0.5) vs 0.35 m/s (IQR 0.28-0.5) in patients without and with AF recurrence, respectively (p = 0.04). Patients without AF recurrence had also higher mitral annular A’ velocity obtained by tissue Doppler imaging (7.4 ± 2.8 cm/s vs 3.5 cm/s, IQR 2.8-4.8; p < 0.0001), LA reservoir strain (19.4 ± 7.3% vs 11%, IQR 9.6-15.3; p = 0.0003) and LA contractile strain (9.4 ± 4.1% vs 2.8%, IQR 1.2-4.4; p < 0.0001). The table presents results derived from univariate Cox regression analysis.
Conclusion
LA activity assessed early after the restoration of sinus rhythm is the predictor of AF recurrence. The strongest association was proven for LA contractile strain. Abstract Figure. Univariate Cox regression analysis

Abstract
Abstract
Introduction
Antazoline (ANT) is an old antihistaminic medication with antiarrhythmic properties. After intravenous administration ANT exerts rapid antiarrhythmic effect often resulting in conversion of atrial fibrillation (AF) to sinus rhythm (SR) and is widely used in Poland for this purpose in the last years. However, published data on its effectiveness, safety and clinical utility for rapid AF termination are limited and ANT is not recognized as a cardioversion drug.
Aim
To assess the real-world efficacy of ANT for pharmacological cardioversion of paroxysmal and persistent non-valvular AF.
Methods
Our single center, retrospective, observational study included patients (pts) with history paroxysmal or persistent AF episode lasting less than 6 months, in stable cardiopulmonary condition who were qualified for elective pharmacological cardioversion with intravenous ANT. The primary end-point was the conversion of AF to SR confirmed in electrocardiography (ECG) during the 6-hours observation.
Results
A total of 176 pts (mean age 68.4±12.0 years, 49% male) were enrolled into the study. In 93 patients (52%) AF duration was shorter than 48 hours and median AF duration time was 24 (7–432) hours. The overall success rate of pharmacological cardioversion of AF with intravenous ANT was 45.5% (80/176 pts). The mean used dose of ANT was 250.9±65.4mg. The subgroup analysis, regarding the AF duration, suggested the effectiveness of ANT mainly in in short-lasting AF (effectiveness of antazoline based cardioversion for AF lasting <48h vs others: 75.3% vs 12.0%, p<0.001). In multivariable logistic regression model AF duration (for every 24h in AF – OR=0.97; 95% CI 0.96–0.98), the left atrium antero-posterior diameter (OR=0.92; 95% CI 0.86–0.99) and the serum creatinine level (OR=0.15; 95% CI 0.03–0.73) were identified as independent predictors of antazoline based pharmacological cardioversion effectiveness, even after adjustment for comorbidities. The ROC curves revealed that the optimal cut-off value for AF duration time predicting ANT's effectiveness was 48h (AUC=0.876; 95% CI 0.815–0.922) – Figure 1. There were only one episode of bradycardia <45 bpm related to ANT administration.
Conclusions
Antazoline is effective and safe in rapid pharmacological cardioversion of paroxysmal AF, especially in the short-lasting AF (<48 hours) and in patients without the left atrium enlargement and significant renal disease.

Abstract
Abstract
Background
The pandemic of COVID-19 significantly changed the treatment of patients with suspicion of ACS and COVID-19 infection. Access to cardiology department and possibility of invasive diagnosis and treatment of ACS are still significantly impaired.
Aim
Our aim was to evaluate the characteristic and prognosis of patients with suspicion of ACS and COVID-19 infection.
Materials and methods
Our department of cardiology was transformed for Covid unit and was dedicated for diagnosis and treatment of patients with suspicion of ACS. COVID-19 confirmed cases were defined by a positive SARS-CoV-2 polymerase chain reaction (PCR) test. From 14th of October 2020 to 14th of March we performed 39 coronary angiographies. We included 39 patients (27 men) with mean age 69±8.5. In that group 11 patients had NSTEMI, 10 patients had STEMI, 2 patients Tako-Tsubo and 16 unstable angina. All patients underwent coronary angiography, and in 27 patients we performed PCI.
Results
In hospital mortality rate was 35% (14 patients). Cardiac arrest was present in 3 (8%) patients and cardiogenic shock in 4 (10%) patients. The rate of NSTEMI was higher in patients who died 7 vs 4 (p=NS) and STEMI were comparable in both groups 4 vs 6, (p=ns). The IL 6 levels in patients who died were 389±278pg/mL, in compare to 101±93pg/mL (p=0.3) who survived. Independent predictors of death were: sex with the OR=1,1 (95% CI: 0.6–2.4), p=0,03 and IL-6 level on admission OR=1,4 (95% CI: 0.6–2.4), p=0,04. There were no statistically significant differences regarding age, left ventricle ejection fraction, CRP levels and oxygen saturation od admission.
Conclusion
This study confirms the higher risk of death in patients with ACS and SARS-CoV-2. In the multivariable analysis only sex and Il-6 level on admission were the independent risk factors of the in hospital death. Further investigations of the underlying physiopathological relations between COVID-19 and ACS are needed.

Abstract
Abstract
Background
Atrial fibrillation (AF) impairs cardiac mechanics and leads to adverse remodelling. Increased left atrial (LA) stiffness reflecting LA reservoir function and left ventricular (LV) filling pressure is one of the symptoms of LA remodelling.
Purpose
To analyse LA stiffness within 24 hours after successful electrical cardioversion and its prognostic value during 2-years follow-up.
Methods
Prospective study involved 71 patients with nonvalvular AF (mean age 64±13 years, 61% male). All patients underwent echo during 24 hours after conversion to sinus rhythm. We analysed standard echocardiographic and Doppler parameters. Using speckle-tracking method we assessed peak LA longitudinal strain in 4- and 2-chamber view. LA stiffness was calculated as the quotient of peak LA longitudinal strain (LA reservoir function) and mean E/E' ratio. The clinical endpoints were predefined as AF recurrence and cardiovascular hospitalization.
Results
Median time of current AF episode was 2 (IQR 0.4–5) months. Standard echo measurements revealed median of LV ejection fraction 55% (IQR 45–58) and median of LA volume indexed to body surface area 42 ml/m2 (IQR 34–51). During follow-up we noticed AF recurrence in 48 (68%) patients and cardiovascular hospitalization in 43 (61%) patients. Median time-to-event was 2.4 (IQR 1 to 6.9) and 7 (IQR 2.1–11) months, respectively. Receiver operating characteristic curve analysis revealed that LA stiffness >0.53 (AUC=0.821; p<0.0001) and >0.95 (AUC=0.788; p<0.0001) were the optimal cut-off values for predicting AF recurrence and cardiovascular hospitalization. Figure presents Kaplan-Meier survival analysis for AF recurrence (A) and for hospitalization (B). Moreover LA stiffness remain statistically significant in multivariate Cox regression analysis even after adjustment for betablockers, antiarrhythmic drugs, coronary artery disease, heart failure and mitral regurgitation. Relative risk was 1.51 (95% CI 1.09–2.09), p=0.01 for AF recurrence and 1.49 (95% CI 1.05–2.13) for cardiovascular hospitalization.
Conclusions
Speckle tracking-derived LA stiffness assessed early after the restoration of sinus rhythm independently predicts AF recurrence and cardiovascular hospitalization.

Conclusions
Intravenous antazoline administration is effective and safe in rapid pharmacological cardioversion of paroxysmal AF, especially in the short-lasting AF (<48 hours) and in patients without the left atrium enlargement and significant renal disease. Abstract Figure.

Background
The restoration of sinus rhythm (SR) improves the mechanical function of the heart.
Purpose
To assess left atrial (LA) function before and within 24 hours after successful electrical cardioversion (EC) and its prognostic value for atrial fibrillation (AF) recurrence during 24 months follow-up.
Methods
Prospective study involved 71 patients with non-valvular AF (mean age 64 ± 13 years, 61% male). All patients underwent echocardiography before and after EC. We analysed standard parameters in two-dimensional echo, pulse-wave Doppler and tissue Doppler echocardiography. Using speckle-tracking method we assessed peak atrial longitudinal strain (PALS) and peak atrial contraction strain (PACS).
Results
During follow-up we noticed AF recurrence in 48 (68%) patients. Median time to AF recurrence was 2.4 (IQR 1 to 6.9) months. Left ventricular ejection fraction as well as E/E’ and PALS assessed during AF were statistically insignificant as potential predictors in univariate regression model. Receiver operating characteristic curve analysis revealed that left atrial volume index >37 ml/m² (AUC = 0.811, p < 0.0001), E/A ratio >2.1 (AUC = 0.828, p < 0.0001), A wave ≤0.4 m/s (AUC = 0.662, p = 0.01), mean E/E’ ratio during sinus rhythm >8.5 (AUC = 0.815, p < 0.0001), mean A’ wave of ≤5.5 cm/s (AUC = 0.848, p < 0.0001), PALS-SR ≤14.1% (AUC = 0.767, p < 0.0001), PACS ≤4.3% (AUC = 0.883, p < 0.0001) were the optimal cut-off values for predicting AF recurrence.
Conclusions
The assessment of LA and diastolic function conducted within 24 hours after successful cardioversion predicts long-term maintenance of sinus rhythm.

Abstract
Abstract
Background
Some studies reported utility of microRNAs in myocardial infarction diagnostic process, whereas their prognostic remains unclear.
Aim
To evaluate the prognostic value of five circulating miRs (miR-1, miR-21, miR-133a, miR-208, miR-499) levels for predicting major adverse cardiac events (MACE), including death, nonfatal myocardial infarction (MI) or cardiovascular rehospitalization (reh.) in patients with NSTE-ACS.
Material and methods
In our prospective, single-center observational study we recruited patients (pts) with NSTE-ACS with symptoms onset <24 hours before the hospital admission and age, gender-matched patients with stable coronary artery disease (SCAD) as controls. Blood was sampled twice (at admission and 4h after in NSTE-ACS and once in SCAD). Relative expression of miRs were calculated using the ΔΔCt method after normalization to the cel-miR-39 spiked-in control. The mean value of miRs relative expression from two time samples in NSTE-ACS pts were used for further analysis. Subjects were categorized according to mean miRs expression at hospital admission into two group (≤ or > median level of miRs).
Results
103 NSTE-ACS pts (median age 67 years, 68% male) were included in this study. During median 1569 (IQR 935–1842) days of follow-up the primary endpoint (MACE) occurred in 66 (64.1%) pts: 18 pts (18.7%) died, 30 pts (20%) presented with MI and 85 pts (56.7%) were readmitted. In a Cox proportional-hazards regression model miR-499 expression > median level (HR=1.82, 95% CI 1.07–3.09) and high-sensitivity troponin T level (HR=1.24, 95% CI 1.05–1.46) were independent predictors of MACE in long term observation, even after adjustment for other covariates (including other miRNAs). Incidence of MI [34% vs 10%, HR=4.1 (2.0–8.5)], rehospitalization for cardiovascular reasons [67% vs 49%, HR=2.1 (1.3–3.3)] and MACE [76% vs 55%, HR=2.2 (1.5–3.5)] was significantly higher in pts with elevated (> median) miR-499 levels at hospital admission. None of analyzed miRNAs was related to long-term mortality, whereas the left ventricular ejection fraction (EF) has been identified as the only one survival predictor (HR=0.95, 95% CI 0.92–0.98).
Conclusions
Elevated miR-499 levels independently of high sensitivity troponin T levels in early phase of NSTE-ACS are related to increased rate of MACE in 4-year follow-up.

Background
Atrial fibrillation (AF) impairs mechanical function of the heart, especially atria and restoration of sinus rhythm (SR) leads to improvement of mechanics. The predicting role of changes in strain parameters for AF recurrence is not established yet.

Prospective study involved 59 patients after successful electrical cardioversion (EC) because of nonvalvular AF (mean age 65±4 years, 47% female). Speckle tracking analysis (STE) was applied to calculate longitudinal strain of LV and LA before EC and within 24 hours after restoration of SR and additionally total left heart strain (TS) defined as a sum of absolute peak LV and LA strain. We calculated change in strain between AF and SR analyses expressed as delta (Δ). During follow-up we noticed AF recurrence in 42 (71%) patients, most of them (93%) during 1st year after EC. Median time of AF recurrence was 3 months.
Results
We noticed significant immediate post-EC improvement in peak LA longitudinal strain (PALS) and LV global longitudinal strain (LVGLS) (table). Unlike CHA2DS2-VASc score, strain parameters were predictors of AF recurrence. Every 1% increment in ΔLVGLS was related with 13% increase in AF recurrence risk (p=0.02) and every 1% increment in ΔPALS and ΔTS were related with 9% decrease in AF recurrence risk (p=0.007 and p=0.0014, respectively). Multivariate analysis revealed ΔTS as a strongest predictor with 9% decrease in AF risk per every 1% increment. The criterion of ΔTS ≤7.5% allows to predict AF recurrence with 81% sensitivity and 63% specificity.
Conclusions
Speckle tracking measurements are able to detect early mechanical changes in LA even within 24 hours of SR and these absolute changes in LVGLS as well as PALS can predict AF recurrence, with optimal stratification by novel parameter - TS.

Background
Left bundle branch block (LBBB) impairs left ventricular (LV) mechanics and can lead to systolic dysfunction. However, LV mechanical changes that differentiate LBBB patients with preserved and reduced LV ejection fraction (LVEF) remain to be clarified.
Purpose
To measure myocardial work (MWI) and myocardial work efficiency (MWE) of the septal and LV lateral wall in patients with LBBB and various degrees of LV dysfunction using non-invasive strain-derived method.
Methods
Fifty-eight LBBB patients without coronary artery disease (mean age 65 ± 13 years, 60% male) were divided into 4 groups based on their LVEF according to current recommendations for cardiac chamber quantification (figure A): normal (n= 25), mildly (n= 16), moderately (n= 11), and severely (n= 6) reduced LVEF. Septal and lateral wall MWI and MWE were estimated by LV pressure-strain loop obtained by echocardiography.
Results
Both MWI (787 mmHg%, 95% CI 651-924 vs 1956 mmHg%, 95% CI 1758-2154; p < 0.0001) and MWE (71%, 95% CI 66-76 vs 85%, 95% CI 82-87; p = 0.0001) were lower in the septum than in the lateral wall. There was a progressive decrease in septal MWI and MWE with the worsening of LVEF (figure B). Conversely, MWI and MWE of the lateral wall were preserved in patients with normal, mildly and moderately reduced LVEF groups. A significant reduction of MWI and MWE in the lateral wall was detected only in patients with severely reduced LVEF (figure C).
Conclusion
In patients with LBBB, impairment in septal myocardial work escalates according to LVEF loss. Septal dysfunction was compensated by the effective myocardial work of the lateral wall in patients with normal, mildly and moderately reduced LVEF. Mechanical dysfunction of the lateral wall was associated with severe reduction of LVEF.

P798 Right atrial phasic function and correlation with right ventricular function in patients with reduced left ventricular ejection fraction and no pulmonary hypertension:insights from 3D echocardiography.

Abstract
Abstract
Background
The right atrium (RA) is a highly dynamic chamber with 3 mechanical functions (reservoir, conduit, booster pump) and prognostic implications in heart failure (HF) and pulmonary hypertension (PH). However, RA function and its interplay with the right ventricular (RV) performance in patients (pts) with reduced left ventricular ejection fraction (LVEF) and without PH remain to be clarified.
Methods
We used three-dimensional echocardiography to study 55 pts (61 ± 14 years, 43 men) with LVEF < 40% no more than mild tricuspid regurgitation (TR), and maximum velocity of the TR jet < 3 m/s. We measured the three-dimensional RA total, passive, active ejection volumes (EV) and the respective emptying fractions (EF). In addition, we compared RV volumes and ejection fraction (RVEF) between patients with normal and abnormal RA function.
Results
Mean LVEF was 30 ± 7%. Mean echo-derived pulmonary vascular resistance was 1.64 ± 0.54 Wood units. 28 pts (51%) had reduced RA reservoir function (total EF = 34 ± 9%), 34 pts (62%) had reduced RA conduit function (passive EF = 15 ± 4%), and 10 pts (18%) had reduced RA pump function (active EF = 11 ± 3%). Pts with reduced RA reservoir function showed larger RV end-systolic volume (RVESV 124 ± 48ml vs. 90 ± 32ml; p = 0.004) and lower RVEF (38 ± 8% vs. 46 ± 6%; p < 0.001) than pts with normal RA function. Pts with reduced RA conduit function showed smaller RV stroke volume (RVSV 65 ± 19 ml vs. 80 ± 22ml; p = 0.009). Pts with impaired RA pump function showed larger RVESV (142 ± 45ml vs. 99 ± 41ml; p = 0.02) and lower RVEF (36 ± 6% vs. 43 ± 8%; p = 0.006).
RVESV was positively correlated with total (r2 = 0.47, p < 0.001), passive (r2 = 0.29, p = 0.03) and active (r2 = 0.39, p = 0.003) RAEV, while it was negatively correlated with total (r2=-0.41, p = 0.002), passive (r2=-0.34, p = 0.01) and active (r2=-0.31, p = 0.02) RAEF. RVSV showed a positive correlation with both total (r2 = 0.4, p = 0.002) and passive (r2 = 0.41, p = 0.002) RAEV. Finally, RVEF was positively correlated with total (r2 = 0.51, p < 0.001), passive (r2 = 0.47, p < 0.001), and active (r2 = 0.36, p = 0.007) RAEF.
Conclusions
RA dysfunction is not uncommon in pts with reduced LVEF, even in the absence of PH. In these pts, RA function is associated with significant changes in RV function. The RA acts as a dynamic modulator of RV pump function by redistributing RV filling and ejection force among reservoir, conduit and pump functions in the setting of altered hemodynamics. The clinical and prognostic significance of RA function in pts with reduced LVEF warrant further studies.

Abstract
Abstract
Purpose
To investigate the relationship between right atrial deformation and the right ventricular size and function.
Methods
94 patients with various cardiovascular pathologies have been included in the study group. All patients underwent transthoracic echocardiography with subsequent off-line analysis using speckle tracking technique and measurement of numerous right atrial deformation parameters, including peak atrial longitudinal strain (PALS) and peak atrial contraction strain (PACS), as well as established indices of right ventricular size and function, including right ventricular basal diameter in apical four-chamber view (RVITd), tricuspid annular peak systolic excursion (TAPSE) and global longitudinal strain (GLS).
Results
There was a statistically significant weak correlation between RA strain (PACS and PALS) and RV parameters. RV-GLS showed significant correlation with PALS (r = -0,38; p = 0,0015) and PACS (r = - 0,30; p = 0,013). Similarly, TAPSE correlated with PALS and PACS (r = 0,34; p = 0,02) and (r = 0,23; p = 0,04) respectively. However, there was no correlation between right atrial function and RVIT.
Conclusions
Right atrial deformation parameters weakly correlate with right ventricular function indices and show no correlation with the size of the right ventricle.

Abstract
Abstract
Background
Atrial fibrillation (AF) is associated with impaired mechanical function of the atria. The restoration of sinus rhythm (SR) leads to improvement of mechanics, however the onset of those changes is not established yet.
Purpose
To analyse changes in left atrial (LA) mechanical function after conversion to SR.
Methods
Forty patients (mean age 65 ± 12 years, 63% male) with nonvalvular AF underwent successful electrical cardioversion. Transthoracic echocardiography with speckle tracking analysis (STE) of LA was performed in AF and within 24 hours after cardioversion, in SR. We analysed standard parameters of left ventricle (LV) and LA. By the use of STE we assessed peak atrial longitudinal strain (PALS), time to PALS indexed to RR interval (TT-PALS/RR) and intra-atrial asynchrony.
Results
Heart rate during echocardiography was higher before cardioversion - median (IQR) 90 beats per minute (80-110) vs 61 (56-72); p < 0.0001. The mean LV ejection fraction in our study group was 48 ± 11%. We noticed significant improvement in LA STE measurements and in early diastolic (E’) mitral annular velocity. There were no significant changes in systolic (S’) mitral annular velocity and in the ratio of transmitral Doppler early filling velocity to E’ (E/E’). Detailed results are present in the table.
Conclusions
Speckle tracking measurements are able to detect early mechanical changes in LA even within 24 hours of SR.
