Sarcoidosis is a systemic chronic granulomatous disease with significant morbidity and mortality. Although basic transthoracic echocardiography (TTE) is not recommended for the assessment of sarcoidosis, speckle tracking echocardiography (STE) has emerged as more sensitive for the early detection of cardiac sarcoidosis and its outcome. The aim of the study was to assess the utility of left atrial and left ventricular longitudinal STE for the prediction of major adverse cardiac events (MACE) and sarcoidosis relapses. We enrolled 172 consecutive patients with sarcoidosis who underwent TTE and pulmonary function tests (PFTs). All patients were followed for a sarcoidosis relapse and MACE. During a median follow-up of 2217 days, 8 deaths, 23 MACE and 36 sarcoidosis relapses were observed. LV global longitudinal strain (GLS) was significantly lower in patients with MACE (p = 0.025). LV-GLS < 17.13% (absolute value) was identified as a fair predictor of MACE. Concerning the sarcoidosis control, TTE revealed a reduction of the LV ejection fraction (p = 0.0432), tricuspid annular plane systolic excursion (p = 0.0272) and global peak atrial longitudinal strain (PALS, p = 0.0012) in patients with relapses. PALS < 28.5% was the best predictor of a sarcoidosis relapse. Our results highlight a potential role of LV-GLS and PALS as prognostic markers in sarcoidosis, supporting the use of STE in the clinical management of these patients.

Abstract Purposes We examined how changes in left ventricular (LV) global longitudinal strain (GLS) were associated with prognosis in patients with preserved LV ejection fraction (LVEF) after congestive heart failure (HF) admission. Methods We studied 123 consecutive patients (age 70 ± 15 years, 55% male) who had been hospitalized due to congestive HF with preserved LVEF (&gt; 50%). The exclusion criteria were atrial fibrillation and inadequate echo image quality for strain analyses. The patients underwent speckle-tracking echocardiography and measurement of plasma NT-ProBNP levels on the same day at the time of hospital admission as well as in the stable condition after discharge. Differences in GLS, LVEF and NT-ProBNP (delta GLS, LVEF and NT-ProBNP ; 2nd – 1st measurements) were calculated. The study end points were all-cause mortality and cardiac events. Results Mean periods of echo performance after hospitalization were 2 ±１days (1st echo) and 240 ± 289 days (2nd echo), respectively. During the follow-up (974 ± 626 days), 12 patients died and 25 patients were hospitalized because of HF worsening. In multivariate analysis, delta GLS and follow-up GLS were prognostic factors, whereas baseline and follow-up LVEF, NT-ProBNP, changes in LVEF and NT-ProBNP could not predict cardiac events. Delta GLS (p = 0.002) turned out to be the best independent prognosticator. Receiver operating characteristics analysis revealed that -0.6% of delta GLS was the optimal cut-off value to predict cardiac events and mortality (sensitivity 76%, specificity 67%, AUC 0.75). Kaplan-Meier analysis showed that patients with delta GLS more than -0.6% experienced significantly less cardiac events during the follow-up period (p &lt; 0.0001, log-rank). Conclusion A change in LV GLS after congestive HF admission was a predictor of the prognosis in patients with preserved LVEF. It would be useful to check the changes in GLS in those with preserved LVEF after discharge.

Abstract Background Sarcoidosis is a chronic granulomatous disease characterized by multiorgan inflammatory involvement and recurrent relapses with significant impact on morbidity and mortality. The prognostic assessment of these patients is still challenging. Although the international guidelines didn't recommend basic transthoracic echocardiography (TTE) for diagnostic and prognostic assessment of sarcoidosis, speckle tracking echocardiography (STE) has emerged as more sensitive for the early detection of cardiac sarcoidosis and outcome. Purpose This prospective study aimed to assess the potential value of STE parameters for the prediction of major adverse cardiac events (MACE) and sarcoidosis relapse. Methods Consecutive patients with confirmed diagnosis of sarcoidosis who underwent transthoracic echocardiography (TTE) and subsequent pulmonary function tests (PFTs) were enrolled. Patients with acute events or treatment escalation between TTE and PFTs and previous cardiac surgery were excluded. All patients were followed for sarcoidosis relapse requiring increase in step-up therapy and MACE (cardiovascular death, cardiovascular hospitalizations, arrhythmias). Results 172 patients were included (111 females, 57.4±12.6 years); 56 patients showed extrapulmonary localizations of sarcoidosis; at baseline, 99 patients were on steroid and/or immunosuppressive therapy. During a median follow up of 2217 days, 8 deaths (3 cardiovascular deaths), 23 MACE and 36 sarcoidosis relapses were reported. Patients with MACE were older (p=0.0022), but didn't show significant differences in PFTs and sarcoidosis phenotype. LV global longitudinal strain (GLS) was the only echocardiographic index to show significant differences (lower values) in patients with MACE (p=0.025). LV GLS ≤17.13% (absolute value) was identified as a fair predictor of MACE both with ROC curves (AUC=0.64) and Kaplan Meier analysis (Fig. 1). No significant differences of demographic, clinical, functional, and therapeutic data were observed between patients with/without sarcoidosis relapse. TTE revealed a significant reduction of LV ejection fraction (p=0.0432), tricuspid annular plane systolic excursion (TAPSE, p=0.0272) and global peak atrial longitudinal strain (PALS, p=0.0012) in patients with relapse. Among these 3 parameters, PALS ≤28.5% showed to be the best predictor of sarcoidosis relapse with ROC (AUC=0.7155) and Kaplan Meier curves (Fig. 2). Conclusions Our results highlight a potential role of LV GLS and PALS as prognostic markers in sarcoidosis, suggesting the use of STE in the clinical management of these patients, regardless the evidence or the suspect of cardiac localizations of the disease.

Abstract Background Cardiovascular disease is a well-recognized cause of increased late morbidity and mortality among survivors of childhood cancer treated with anthracyclines. A decrease in left ventricular (LV) ejection fraction (LVEF) and fractional shortening may be observed during follow-up. Previous studies reported non-negligible prevalence of subclinical systolic dysfunction assessed with deformation imaging at short-, mid- and long-term follow up. Co-administration of Dexrazoxane has been shown to significantly reduce short-term and mid-term cardiotoxicity. The usefulness of dexrazoxane in preventing late (&gt;10 years) anthracycline cardiotoxicity remains under discussion. Purpose Aim of this study was to assess cardiac function in long-term (&gt;10 years) survivors of childhood tumors treated with dexrazoxane/anthracycline association. Methods Twenty cancer survivors previously treated with co-administration of anthracyclines and dexrazoxane for childhood renal tumors or sarcoma and a control group of 20 healthy non-athletic subjects matched for age, sex and body surface area were enrolled in the study. Echocardiographic measurements included 3D LVEF and LV and right ventricular (RV) global longitudinal strain (GLS). Cancer survivors were evaluated at median follow-up time of 21.5 years (range 10-26). Results No evidence of cardiac toxicity, as defined by current guidelines, was reported in all survivors. None of survivors presented LVEF &lt; 50% or abnormal longitudinal strain, defined as a value &gt;2 SDs below the mean using sex-specific and age-specific strain values. No significant differences in standard and deformation imaging parameters were observed between survivors and controls (3D LVEF 58 ± 3 % vs 60 ± 5 % p = NS; LV GLS -21 ± 1 % vs - 21 ± 2 % p= NS; RV GLS - 23 ± 2 % vs - 23 ± 5 % p= NS). Moreover, considering subjects who received a cumulative dose of anthracyclines above the median (doxorubicin-equivalent dose ≥208 mg/m2) no significant differences were found as compared to the group receiving a lower dose. Conclusions No evidence of cardiac toxicity was detected in all survivors. Our findings support the cardio-protective role of dexrazoxane in children undergoing anthracycline-based treatment.

Objectives: Previous studies have demonstrated that myocardial longitudinal strain and strain rate is decreased in asymptomatic patients treated with anthracyclines. In this study, the relation between global myocardial longitudinal strain, conventional echocardiographic parameters, NT-pro-BNP levels, cumulative anthracycline dosage and follow up duration was investigated in a large group of asymptomatic long term survivors of childhood cancer. Methods: 79 asymptomatic survivors (45% children) underwent a detailed echocardiographic examination for obtaining conventional parameters and global myocardial longitudinal strain values in 4-chamber view. In addition to this, we collected blood samples for NT-pro-BNP estimation. Results: the survivors had a mean age of 20 years (range: 6 –37 years), a mean follow up duration of 14 years (range 5–27 years) and a mean cumulative anthracycline dose of 240 mg/m 2 (range 50 –524 mg/m 2 ). Reduced global myocardial longitudinal strain was significantly related to an EF<55% (p<0.001) and to reduced left ventricular posterior wall thickness in diastole indexed by body surface area (LVPWd/BSA) (p<0.003). Reduced myocardial global longitudinal strain was not related to abnormal NT-pro-BNP levels, follow up duration and cumulative anthracycline dosage. Conclusion: reduced global myocardial longitudinal strain is related to subclinical heart failure, e.g. abnormal EF and reduced LVPWd/BSA in asymptomatic survivors of childhood cancer. The role of myocardial strain in the early detection of anthracycline-induced cardiotoxicity needs to be explored by further longitudinal prospective studies.

Introduction: The optimal timing of mitral valve (MV) surgery in patients with organic mitral regurgitation (OMR) is controversial. The objective of this study was to determine independent predictors of cardiac events in patients with OMR and no triggers for mitral valve surgery. Hypothesis: We hypothesized that forward LV ejection fraction (LVEF) calculated by the Dumesnil’s method (i.e. stroke volume measured in LV outflow tract divided by left ventricular end diastolic volume) is superior to the LVEF measured by the biplane Simpson’s method. Methods: Two hundred seventy eight patients with OMR (i.e. severity grade ≥1/4) and Doppler echocardiography exam at least 6 months before MV surgery or death were included. Clinical and echocardiographic data of 278 patients with OMR were analyzed retrospectively. The study end-point was the composite of death or need for mitral valve surgery. Results: During a mean follow-up of 5.4 ± 3.2 years, there were 147 (53%) events: 96 (35%) mitral surgeries and 66 (24%) deaths. There was no difference in the Simpson LVEF (65 ± 6% vs 65 ± 4%; p=0.86) and global longitudinal strain (-21.18 ± 3.26 % vs -21.26 ± 2.44 %; p=0.86) between patients who had an event versus those who were event-free during follow-up. However, LVEF calculated by Dumesnil’s method at baseline was lower in the event-group (47 ± 15%vs 59 ± 15%; p<0.0001) compared to the non-event group. After adjustment for age, sex, Charlson’s probability, coronary artery disease, ACE inhibitors, β-blockers, diuretics, AF and MR grade, forward LVEF by Dumesnil’s method remained an independent predictor of the occurrence of cardiac events (adjusted hazard ratio: 1.09, 95% interval confidence: 1.02-1.17; p=0.01). Conclusion: This study shows that the forward LVEF calculated by the Dumesnil’s method is superior to the standard LVEF or to longitudinal strain to predict outcomes in OMR. These results could help to improve risk stratification of patients with OMR and thereby individualized the treatment’s strategy. Further prospective studies are needed to confirm these findings.

Abstract 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. Purpose To analyse changes in left atrial (LA) and left ventricular (LV) mechanical function after conversion to SR and their prognostic values for AF recurrence during 24 months follow-up. Methods 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.

Abstract Background Few studies have assessed the evolution of cardiac chambers deformation imaging in patients with atrial fibrillation (AF) according to cardiac rhythm outcome. Purpose To evaluate cardiac chamber deformation imaging in patients admitted for AF and the evolution at 6-month follow-up (M6). Methods In forty-one consecutive patients hospitalised for AF two-dimensional transthoracic echocardiography was performed at admission (M0) and after six months (M6) of follow up. In addition to the usual parameters of chamber size and function, chamber deformation imaging was obtained including global left atrium (LA) and right atrium (RA) reservoir strain, global left ventricular (LV) and right ventricular (RV) free wall longitudinal strain. Patients were divided into three groups according to their cardiac rhythm at M0 and M6: AF at M0 and sinus rhythm (SR) at M6 (AF-SR) (n=23), AF at M0 and AF at M6 (AF-AF) (n=11), SR at M0 (spontaneous conversion before the first echocardiography exam) and SR in M6 (SR-SR) (n=7) Results In comparison with SR patients (n=7), at M0, AF patients (n=34)) had lower global LA reservoir strain (+5.2 (+0.4 to 12.8) versus +33.2 (+27.0 to +51.5)%; p&lt;0.001), lower global RA reservoir strain (+8.6 (−5.4 to 11.6) versus +24.3 (+12.3 to +44.9)%; p&lt;0.001), lower global LV longitudinal strain (respectively −12.8 (−15.2 to −10.4) versus −19.1 (−21.8 to −18.3)%; p&lt;0.001) and lower global RV longitudinal strain (respectively −14.2 (−17.3 to −10.7) versus −23.8 (−31.1 to −16.2)%; p=0.001). When compared with the AF-SR group at M0 the AF-AF group had no significant differences with regard to global LA and RA reservoir strain, global LV and RV longitudinal strain (Table). Between M0 and M6 there was a significant improvement in global longitudinal strain of the four chambers in the AF-SR group whereas no improvements were noted in the AF-AF and SR-SR group (Figure). Conclusion Initial atrial and ventricular deformations were not associated with rhythm outcome at six-month follow up in AF. The improvement in strain in all four chambers strain suggests global reverse remodelling all cardiac cavities with the restoration of sinus rhythm.

AbstractTo determine whether left ventricular (LV) global longitudinal strain (GLS) measured by feature-tracking (FT) cardiac magnetic resonance (CMR) improves after kidney transplantation (KT) and to analyze associations between LV GLS, reverse remodeling and myocardial tissue characteristics. This is a prospective single-center cohort study of kidney transplant recipients who underwent two CMR examinations in a 3T scanner, including cines, tagging, T1 and T2 mapping. The baseline exam was done up to 10 days after transplantation and the follow-up after 6 months. Age and sex-matched healthy controls were also studied for comparison. A total of 44 patients [mean age 50 ± 11 years-old, 27 (61.4%) male] completed the two CMR exams. LV GLS improved from − 13.4% ± 3.0 at baseline to − 15.2% ± 2.7 at follow-up (p < 0.001), but remained impaired when compared with controls (− 17.7% ± 1.5, p = 0.007). We observed significant correlation between improvement in LV GLS with reductions of left ventricular mass index (r = 0.356, p = 0.018). Improvement in LV GLS paralleled improvements in LV stroke volume index (r = − 0.429, p = 0.004), ejection fraction (r = − 0.408, p = 0.006), global circumferential strain (r = 0.420, p = 0.004) and global radial strain (r = − 0.530, p = 0.002). There were no significant correlations between LV GLS, native T1 or T2 measurements (p > 0.05). In this study, we demonstrated that LV GLS measured by FT-CMR improves 6 months after KT in association with reverse remodeling, but not native T1 or T2 measurements.
