Abstract Funding Acknowledgements Type of funding sources: None. Background High-flow nasal cannulae oxygen therapy (HFNCOT) represents a better tolerated alternative to non-invasive pressure support ventilation (NIPSV) for acute cardiogenic pulmonary edema (ACPE) treatment. However, there are still few data on the effect of HFNCOT on cardiac function and hemodynamic. Purpose To assess and compare the effects of NIPSV and HFNCOT in ACPE setting on right ventricular (RV) systolic function and on indices of cardiac filling and output, as measured by echocardiography.  Methods  This is a cross-over controlled study, enrolling 15 consecutive patients admitted to our Cardiovascular Intensive Care Unit for ACPE and hypoxaemic, normo/hypocapnic acute respiratory failure, with P/F ratio < 200. Each patient received NIPSV, followed by HFNCOT. Full echocardiographic assessment and blood gas analysis (BGA) were performed 40 minutes from onset of each ventilation modality, respectively before NIPSV to HFNCOT switch and before HFNCOT interruption. In particular, RV function parameters, together with RV and atrial strain, were prospectively collected. Results  In spite of not significant changes in BGA, RV function was significantly improved under HFNCOT, as compared to NIPSV, as assessed by the following parameters: tricuspid annular plane excursion (TAPSE) (P = 0.001), RV S’ wave (P = 0.007), RV fractional area change (RVFAC) (P = 0.006). Strain analysis confirmed the significant improvement in RV function, with free wall global longitudinal strain (GLS) and free wall and septum GLS significantly higher under HFNCOT, as compared to NIPSV (-21% vs -18% P < 0.001, and -15% vs -19% P = 0.008, respectively,), and a significant increase in right atrial positive longitudinal strain (P < 0.001).  Conclusions NIPSV significantly affect RV function making more complex the management of patients presenting with ACPE. In this setting, HFNCOT represents a valuable alternative, providing similar respiratory outcomes while preserving good right ventricle performance.

Abstract Background/Introduction Speckle tracking echocardiography has been recently proposed as an accurate and sensitive measure of right ventricle (RV) function that could integrate other more conventional parameters. This tool can be important in the clinical context of severe tricuspid regurgitation (TR), since TAPSE is not fully representative of global RV function and can overestimate this in presence of severe TR. Purpose Evaluate the prognostic relevance of different parameters of RV structure and function derived from 2D and speckle tracking echocardiographic analysis of clinically stable patients with severe TR referred for routine follow up in the context of many etiologies of left side heart disease (secondary TR). Methods The present is a retrospective analysis of prospectively acquired echocardiographic studies including patients with severe secondary TR in the context of left side heart disease. Fractional area change (FAC), tricuspid annular plane systolic excursion (TAPSE), RV global longitudinal strain (RVLS) and RV free-wall longitudinal strain (RVFWLS) as well as LV function were measured. As suggested in previous studies, we also aimed to explored the use in this population of: i)RVLS/pulmonary systolic arterial pressure (PASP); ii) RVFWLS (average lateral 3 segments strain)/IVSLS (average medial 3 segment strain) as index of RV-LV dependency. The composite end-point of this study included death for any cause and heart failure hospitalization. Results 61 patients (mean age 58±20 years, 65% men), were included. After a mean follow up period of 3,6±2 years 57% of patients reached the combined end-point. At Cox regression univariate analysis a significant correlation with outcomes was found for RVend-diastolic diameter (HR 0,42, p: 0.018), right atrial area (HR: 3, p: 0.02), RVFWLS/IVSLS (HR: 0.5, p: 0.020), RVLS/PASP (HR 0.186, p: 0.039). In multivariable Cox-regression model we found that LVEF, RV dimension and RVFWLS/IVSLS were independently related to outcome; this last one parameter showed the best correlation with outcomes. Conclusions In asymptomatic and clinically stable patients with severe secondary TR longitudinal function of RV free wall is not related to outcomes but RV-arterial coupling and the ratio between deformation of free wall and septal wall of RV are good predictors of clinical deterioration at follow up. The last one conceptually represents the interaction between RV and LV in secondary TR and allows a real “correction” of those effects of severity of TR on the base to apex gradient of lateral wall longitudinal deformation (TR increases movement of basal segments).

Abstract Introduction Precapillary pulmonary hypertension (pPH) causes right ventricular (RV) pressure overload inducing RV remodeling, often resulting in dysfunction and dilatation, heart failure, and ultimately death. The ability of the right ventricle to adequately adapt to increased pressure loading is key for patients' prognosis. RV ejection fraction (RVEF) by cardiac magnetic resonance (CMR) is related to outcome in pPH patients, but this global measurement is not ideal for detecting early changes in RV function. Strain analysis on CMR using feature tracking (FT) software provides a more detailed assessment, and might therefore detect early changes in RV function. Aim 1) To compare RV strain parameters in pPH patients and healthy controls, and 2) to compare strain parameters in a subgroup of pPH patients with preserved RVEF (pRVEF) and healthy controls. Methods In this prospective study, a CMR was performed in pPH patients and healthy controls. Using FT-software on standard cine images, the following RV strain parameters were analyzed: global, septal, and free wall longitudinal strain (GLS, sept-LS, free wall-LS), time to peak strain (TTP, as a % of the whole cardiac cycle), the fractional area change (FAC), global circumferential strain (GCS), global longitudinal and global circumferential strain rate (GLSR and GCSR, respectively). A pRVEF is defined as a RVEF >50%. To compare RV strain parameters in pPH patients to healthy controls, the Mann-Whitney U test was used. Results 33 pPH-patients (55 [45–63] yrs; 10 (30%) male) and 22 healthy controls (40 [36–48] yrs; 15 (68%) male) were included. All RV strain parameters were significantly reduced in pPH patients compared to healthy controls (see table), except for GCS and GCSR. Most importantly, in pPH patients with pRVEF (n=8) GLS (−26.6% [−22.6 to −27.3] vs. −28.1% [−26.2 to −30.6], p=0.04), sept-LS (−21.2% [−19.8 to −23.2] vs. −26.0% [−24.0 to −27.9], p=0.005), and FAC (39% [35–44] vs. 44% [42–47], p=0.02) were still significantly impaired compared to healthy controls. The RV TTP was significantly increased in pPH patients compared to healthy controls (47% [44–57] vs. 40% [33–43], p≤0.001). Conclusions Several CMR-FT strain parameters of the right ventricle are impaired in pPH patients when compared to healthy controls. Moreover, even in pPH patients with a preserved RVEF multiple RV strain parameters (GLS, sept-LS, and FAC) remained significantly impaired, and TTP significantly prolonged, in comparison to healthy controls. This suggests that RV strain parameters may be used as an early marker of RV dysfunction in pPH patients. Funding Acknowledgement Type of funding source: None

Abstract Aims Myocardial work (MW) is a novel parameter that can be used in a clinical setting to assess left ventricular (LV) pressures and deformation. We sought to distinguish patterns of global MW index in hypertensive vs. non-hypertensive patients and to look at differences between categories of hypertension. Methods and results Sixty-five hypertensive patients (mean age 65 ± 13 years; 30 male) and 15 controls (mean age 38 ± 12 years; 7 male) underwent transthoracic echocardiography at rest. Hypertensive patients were subdivided into Stage 1 (n = 32) and Stage 2 (n = 33) hypertension based on 2017 American College of Cardiology guidelines. Exclusion criteria were suboptimal image quality for myocardial deformation analysis, reduced ejection fraction, valvular heart disease, intracardiac shunt, and arrhythmia. Global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency were estimated from LV pressure–strain loops utilizing proprietary software from speckle-tracking echocardiography. LV systolic and diastolic pressures were estimated using non-invasive brachial artery cuff pressure. Global longitudinal strain and LV ejection fraction were preserved between the groups with no statistically significant difference, whereas there was a statically significant difference between the control and two hypertension groups in GWI (P = 0.01), GCW (P < 0.001), and GWW (P < 0.001). Conclusion Non-invasive MW analysis allows better understanding of LV response under conditions of increased afterload. MW is an advanced assessment of LV systolic function in hypertension patients, giving a closer look at the relationship between LV pressure and contractility in settings of increased load dependency than LV ejection fraction and global longitudinal strain.

Abstract Funding Acknowledgements ESC Training Grant 2019 Background Non-invasive prediction of critical coronary artery stenosis (CCS) is challenging. CCS may cause persistent impaired longitudinal function at rest, which could be detected by two-dimensional speckle tracking echocardiography (2D-STE). However, strain parameters are load dependent, hence they might not reflect systolic function accurately. A novel non-invasive method to calculate MW recently showed a strong correlation with invasive work measurements. Objectives To investigate the ability of non-invasive Myocardial Work (MW) indices: 1) to identify the ischaemic risk area during acute coronary occlusion (ACO); 2) to predict the ischaemic risk area underlying a CCS before coronary angiography. Methods The study population comprises 80 individuals: fifty consecutive patients (pts) referred for coronary angiography in a single tertiary coronary care centre and thirty controls (CTRL). Echocardiography recordings (GE-Healthcare) with systolic and diastolic non-invasive pressures, were obtained immediately before coronary angiography, during ACO, and immediately after revascularization to measure longitudinal strain along with myocardial work indices: Myocardial Work Index (MWI), Myocardial Constructive Work (MCW), Myocardial Wasted work (MWW), Myocardial work efficiency (MWE). Results Compared to baseline, we found a significant reduction of global longitudinal strain (GLS) (p = 0.005), MWI, MCW and MWE (p < 0.001) during ACO. After the procedure, we observed a significant improvement in GLS, MWI, MCW and MWE (p < 0.001) compared to the findings obtained during CO. Interestingly, baseline global MWI, MCW and MWE were significantly reduced in pts with CCS at angiography compared to controls (p < 0.05). Moreover, regional MWE, but not longitudinal strain, measured within the myocardial segments underlying the CCS, was significantly reduced compared to non-target segments (p < 0.001). Conclusions Our results demonstrate that non-invasive estimation of regional and global MW parameters are able to identify myocardial ischemia upon ACO. Moreover, myocardial work indices measured at rest were able to predict the presence of CCS before invasive angiography, whereas MWE was more sensitive than myocardial strain to document regional impairment of myocardial function.

Abstract Background The function of both ventricles have been suggested to be affected in patients with mitral stenosis. In this study, it was aimed to investigate deformation properties of right (RV) and left ventricles (LV) in mild and moderate rheumatic mitral stenosis (MS) patients with three-dimensional speckle tracking echocardiography (3D-STE). Methods A total of 60 patients were included in the study (20 patients with mild MS diagnosis, 20 patients with moderate MS diagnosis and 20 healthy volunteers). Three-dimensional echocardiography datasets were obtained for both ventricles in all patients. An example for RV assessment is shown in Figure 1. LV global longitudinal strain (GLS), LV torsion, RV free wall (FW) LS and interventricular septal (IVS) LS measurements were analyzed. Results The LV ejection fraction (EF), RV fractional area change and tricuspid annular plane systolic excursion values were statistically similar and in the normal range. The LV GLS measurements were significantly different among the groups by being highest in the control group and least in the moderate stenosis group (ANOVA,p < 0.001) (Table 1). Patients with MS showed higher torsional values, correlated with MS severity (ANOVA,p < 0.001) (Table 1). IVS LS, RVFW LS values obtained by RV analysis also differed significantly among groups. The FW-GLS values only showed significant difference between the control group and moderate MS group (Table 1). Conclusion Patients with mitral stenosis showed lower LV-GLS and higher LV torsion values. Although the LV GLS is affected; the LV EF was detected to be normal due to increase in LV torsion. RV deformation indices showed signıficant decrease in correlation with the severity of the mitral stenosis. In conclusion, our data suggest that subclinical LV and RV systolic dysfunction is present in mild-moderate MS patients and this dysfunction can be detected by 3D-STE.

Abstract Background Evolution of left and right ventricular (LV and RV) function after heart transplantation (HT) has not been well described. Our objective was to evaluate the normal evolution of echocardiographic parameters of both ventricles and to explore if there is a link between the decrease of strain values and acute rejection (AR) or coronary allograft vasculopathy (CAV) Methods We followed 29 HT recipients with serial echocardiograms performed between 2011 and 2018, with a median follow-up of 5 years. LV global longitudinal strain (LV GLS) was analyzed by speckle tracking in 12 LV segments in 4 and 2 chamber views, and RV free wall longitudinal strain (RV free Wall LS) was measured in 4 chamber view. Acute rejection was diagnosed by EMB following our HT protocol. We take into consideration only moderate or severe rejection episodes (grade ≥2R).The presence of CAV was studied by coronariography or IVUS one year post-HT. Results As shown in the table below, LVEF was preserved from the begining of the follow up while LV GLS reached the normality in the 6th month, and both remained in normal ranges untill the 5th year. Regarding RV function, TAPSE was impaired in the early post-HT period and increased progressively and reached normality 1 year after HT. RV lateral wall LS rose during follow-up as well, reaching normal values 6 months after HT. Nevertheless, we noticed an impairment in this parameter at 5 years (−20.1±2.7, p=0.001), although it remained within normal ranges compared to guidelines reference parameters. We did not find any correlation between any parameter evaluated and the presence of AR or CAV at five years of follow-up. LV and RV function parameters LVEF LV GLS TAPSE FAC RV free wall LS Basal (14 days) 63.0±7.9 −17.2±3.6 12.1±2.9* 43.7±9.8 −19.3±4.2 3 months 65.0±8.6 −17.7±2.8 14.8±3.4* 45.3±8.2 −22.0±4.6 6 months 65.8±9.6 −18.7±3.4 16.1±3.6 44.6±9.6 −24.6±4.9* 1 year 63.5±8.1 −18.1±2.2 17.1±4.1 44.0±8.1 −26.7±7.1* 2 years 63.8±6.8 −18.3±9.0 19.4±3.7 45.3±7.9 −27.6±6.3* 5 years 64.4±7.3 −18.1±3.3 17.9±3.9 46.6±12.1 −20.1±2.8 P (Anova) 0.85 0.85 <0.001 0.82 <0.001 Conclusion As we show in this series of HT recipients with uneventful postoperative course, all LV and RV function parameters showed normal values 1 year after HT and manteined them during long-term follow-up. The presence of AR or CAV did not have any influence in ventricular function.

Abstract Aims Non-invasive myocardial work (MW) quantification has emerged in the last years as an alternative echocardiographic tool for myocardial function assessment. This new parameter provides a less loading-dependent evaluation of myocardial performance through the combined assessment of global longitudinal strain (GLS) and non-invasive left ventricle (LV) pressures. The role of MW as a marker of cardiac dysfunction and reverse remodelling in patients with severe aortic stenosis (AS) after aortic valve implantation (TAVI) has not been adequately investigated. This study aims to evaluate MW indices as early echocardiographic markers of LV reverse remodelling within a month after TAVI and their prognostic value. Methods and results We conducted a single-centre prospective study, enrolling 70 consecutive patients (mean age 80.1 ± 5.5 years) with severe AS undergoing TAVI between 2018 and 2020, selected from the EffecTAVI registry. Exclusion criteria were prior valve surgery, severe mitral stenosis, permanent atrial fibrillation, left bundle branch block (LBBB) at baseline, and suboptimal quality of speckle-tracking image analysis. Echocardiographic assessment was performed before TAVI and at 30-day follow-up. Clinical, demographic, and resting echocardiographic data were recorded, including quantification of 2D global longitudinal strain (GLS), global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE). LV peak systolic pressure was estimated non-invasively from the sum of systolic blood pressure and trans-aortic mean gradient. One month after the procedure, there was a significant improvement of LV GLS (−17.94 ± 4.24% vs. −19.35 ± 4.31%, before and after TAVI respectively, P = 0.002), as well as a significant reduction of GWI (2430 ± 586 mmHg% vs. 1908 ± 472 mmHg%, P &lt; 0.001), GCW (2828 ± 626 mmHg% vs. 2206 ± 482 mmHg%, P &lt; 0.001), and GWW (238 ± 207 mmHg% vs. 171 ± 118 mmHg%, P = 0.006). Conversely, MWE did not significantly change early after intervention (90.53 ± 6.05% vs. 91.45 ± 5.05%, P = 0.204). After TAVI, 30 patients (42.8%) developed LV dyssynchrony due to LBBB or pacemaker implantation. When the population was divided according to the presence or absence of LV dyssynchrony at 30-day follow-up, a significant reduction in GWW was found only in those without dyssynchrony (244 ± 241 vs. 141 ± 110 mmHg% with and without dyssynchrony respectively, P = 0.002). Consistently, in this subgroup, MWE significantly improved post-TAVI (90 ± 7 vs. 93 ± 5%, P = 0.002), while a trend of MWE reduction was observed in patients who developed dyssynchrony post-TAVI (91 ± 4 vs. 89 ± 5%, P = 0.164). In the overall population, a baseline value of MWE&lt; 92% was associated with an increased rate of cardiovascular events (composite of all-cause death and rehospitalization for heart failure) at 1-year follow-up (22.2 vs. 3.1%, long rank, P = 0.016). Conclusions In patients with severe AS undergoing TAVI a significant reduction of GWW and improvement of MWE can be detected only in those who did not develop LV dyssynchrony. In this setting, MWE lower than 92% at baseline is associated with poor outcome. Thus, MWE could represent an alternative tool for myocardial function assessment in patients receiving TAVI.

Abstract Background Anthracycline agents are routinely used for treatment of many types of malignancy, while imposing the risk for cardiotoxicity (AT-CMP). Although the right ventricle (RV) is more susceptible to cardiotoxicity, most of the studies have focused on left ventricle (LV) function for monitoring AT-CMP. In this study, we have focused on RV function before and after chemotherapy using two-dimensional speckle tracking Echocardiography (2D-STE). Material and Methods In this prospective study, newly diagnosed and untreated cancerous patients without previous cardiovascular diseases were enrolled. For all patients, baseline echocardiography was performed before the initiation of the anthracycline regimen and after 6 months of follow up when the chemotherapy was stopped. Several parameters of LV and RV function were measured using 3D echocardiography and STE techniques. Results 60 patients were enrolled in the study. There was a significant decrease (P = 0.001) in RV fractional area change (53.57 %±4.36 vs. 45.66% ±6.19), RV Global longitudinal strain (GLS) (− 22.93%±1.95 vs. −18.53 ± 2.75), and RV free wall strain (FWLS) (− 25.75%±3.01 VS. −20.30 ± 3.78). There was a significant decline in LVEF (59.42 ± 6.36% vs. 51.1 ± 6.31%) and LV-GLS (-21.1 ± 1.8% vs -18.6 ± 2.6%) (both P = 0.001) as well. Among the parameters changed following chemotherapy, RV-FWLS was dropped to a pathological level in 25% of patients showing the highest potential for detection of anthracyclines effect on the myocardium. Conclusion Anthracycline therapy can induce subclinical RV dysfunction. RV-FWLS may be proposed as the most sensitive echocardiographic marker for monitoring AT-CMP. This finding needs to be confirmed in future and larger studies.
