Abstract Background Right ventricular (RV) systolic function is determinant in the evaluation of patients with significant tricuspid regurgitation (TR). Timely detection of RV dysfunction with conventional 2D echocardiography is limited by the geometry and position of the RV. RV strain has emerged as an accurate and sensitive tool for evaluation of RV function with the capability of detect subclinical RV dysfunction Purpose This study was aimed to evaluate the prognostic value of RV strain in consecutive patients with significant TR, in comparison with conventional parameters of RV systolic function. Methods Consecutive patients in stable clinical status with significant TR (severe, massive or torrential TR) evaluated in the Heart Valve Clinic were included. RV systolic function was measured with conventional echocardiographic parameters (RV fractional area change [FAC], tricuspid annular plane systolic excursion [TAPSE]), DTI S wave (S') and with STE derived automatic peak global and free wall longitudinal strain (GLS, FW-LS respectively) using the EPIQ system (Philips Medical Systems, Andover, Massachusetts). A combined endpoint of hospital admission due to right heart failure or cardiovascular mortality was defined. Results A total of 130 patients were included (mean age was 75±17 years, 69% females, 93% in NYHA I/II). According to etiology, 14% were primary TR and 86% were functional (49% due to corrected left valve disease and 37% due to tricuspid annulus dilatation). Mean values of RV function parameters are shown in the table. During a mean follow up of 18±8 months, n=39 patients (30%) reached the combined endpoint. Patients with events showed impaired RV GLS and FW-LS. Both parameters were predictive of the combined endpoint (table 1). Conventional parameters of RV systolic function were not associated with outcomes (p>0.05 for all). Conclusion In patients with severe TR, RV strain values are superior to conventional parameters to detect RV dysfunction. Among different measurements of RV function, RV GLS and FW-LS were the only predictors of poor prognosis. These parameters should be included in the serial evaluation of these patients.

Timely detection of RV dysfunction with conventional 2D echocardiography is limited by the geometry of the RV. RV strain has emerged as an accurate and sensitive tool for evaluation of RV function that can allow detection of subclinical RV dysfunction Purpose This study was aimed to evaluate the prognostic value of RV strain in stable patients with significant TR, in comparison with conventional parameters of RV systolic function. Methods Consecutive patients in stable clinical status with significant TR evaluated in the Heart Valve Clinic between 2015–2018 were included. RV systolic function was measured with conventional echocardiographic parameters (RV fractional area change [FAC], tricuspid annular plane systolic excursion [TAPSE]), DTI S wave (`S) and with STE derived peak global and free wall longitudinal strain (GLS, FW-LS respectively) using the EPIQ system. End-point included cardiovascular mortality, tricuspid valve surgery or heart failure Results A total of 70 patients were included (mean age was 74±8 years, 71% females). 5 patients were excluded due to poor acoustic window. According to ethyology, 94% were functional TR (60% due to left valve disease, 27% due to tricuspid annulus dilatation, 13% others). Mean values of RV function parameters are shown in the table. During a median follow up of 18 months [IQR: 4–28], 37% of the patients reached the combined end point (n=15 developed right heart failure, n=17 underwent tricuspid valve surgery, and n=3 died).

Background: Presence of severe tricuspid regurgitation (TR) has a significant impact on assessment of right ventricular function (RVF) in transthoracic echocardiography (TTE). High trans-valvular pendulous volume leads to backward-unloading of the right ventricle. Consequently, established cut-offs for normal systolic performance may overestimate true systolic RVF. Methods: A retrospective analysis was performed entailing all patients who underwent TTE at our institution between 1 January 2013 and 31 December 2016. Only patients with normal left ventricular systolic function and with no other valvular lesion were included. All recorded loops were re-read by one experienced examiner. Patients without severe TR (defined as vena contracta width ≥7 mm) were excluded. All-cause 2-year mortality was chosen as the end-point. The prognostic value of several RVF parameters was tested. Results: The final cohort consisted of 220 patients, 88/220 (40%) were male. Median age was 69 years (IQR 52–79), all-cause two-year mortality was 29%, median TAPSE was 19 mm (15–22) and median FAC was 42% (30–52). In multivariate analysis, TAPSE with the cutoff 17 mm and FAC with the cutoff 35% revealed non-significant hazard ratios (HR) of 0.75 (95%CI 0.396–1.421, p = 0.38) and 0.845 (95%CI 0.383–1.867, p = 0.68), respectively. TAPSE with the cutoff 19 mm and visual eyeballing significantly predicted survival with HRs of 0.512 (95%CI 0.296–0.886, p = 0.017) and 1.631 (95%CI 1.101–2.416, p = 0.015), respectively. Conclusions: This large-scale all-comer study confirms that RVF is one of the main drivers of mortality in patients with severe isolated TR. However, the current cut-offs for established echocardiographic parameters did not predict survival. Further studies should investigate the prognostic value of higher thresholds for RVF parameters in these patients.

Background Severe tricuspid regurgitation (TR) should be intervened before the development of irreversible right ventricular (RV) dysfunction. However, current guidelines do not provide criterion related to RV systolic function to guide optimal surgical timing. We investigated the prognostic value of RV longitudinal strain in patients undergoing isolated surgery for severe functional TR. Methods and Results We enrolled 115 consecutive patients (aged 62±10 years; 23.5% men; 62.6% [n=72] with previous left‐sided valve surgery) who underwent isolated surgery for severe functional TR at 2 tertiary centers. Preoperative clinical and echocardiographic parameters, including RV free‐wall longitudinal strain (RVFWSL), were collected. The primary end point was a composite of cardiac death and unplanned readmission attributable to cardiovascular causes 5 years after surgery. Forty patients (34.8%) reached the primary end point during 333 person‐years of follow‐up. There were 11 cardiac deaths and 34 unplanned readmissions attributable to cardiovascular causes, with 5 patients experiencing both. An absolute preoperative RVFWSL <24% was associated with the primary end point (hazard ratio, 2.30; 95% CI, 1.22–4.36; P =0.011), independent of clinical risk factors, including European System for Cardiac Operative Risk Evaluation II and hemoglobin levels. Meanwhile, other conventional echocardiographic measures of RV systolic function were not significant. The addition of an absolute RVFWSL <24% provided incremental prognostic value to the clinical model for predicting the primary end point. Conclusions Preoperative RVFWSL as an indicator of RV dysfunction was an independent prognosticator in patients undergoing isolated surgery for severe functional TR. Thus, preoperative RVFWSL could help determine the optimal surgical timing for severe functional TR.

Right ventricular (RV) dysfunction occurs following lung resection and is associated with post-operative complications and long-term functional morbidity. Accurate peri-operative assessment of RV function would have utility in this population. The difficulties of transthoracic echocardiographic (TTE) assessment of RV function may be compounded following lung resection surgery, and no parameters have been validated in this patient group. This study compares conventional TTE methods for assessing RV systolic function to a reference method in a lung resection population. Right ventricular index of myocardial performance (RIMP), fractional area change (FAC), tricuspid annular plane systolic excursion (TAPSE) and S′ wave velocity at the tricuspid annulus (S′), along with speckle tracked global and free wall longitudinal strain (RV-GPLS and RV-FWPLS respectively) are compared with RV ejection fraction obtained by cardiovascular magnetic resonance (RVEFCMR). Twenty-seven patients undergoing lung resection underwent contemporaneous CMR and TTE imaging; pre-operatively, on post-operative day two and at 2 months. Ability of each of the parameters to predict RV dysfunction (RVEFCMR<45%) was assessed using the area under the receiver operating characteristic curve (AUROCC). RIMP, FAC and S′ demonstrated no predictive value for poor RV function (AUROCC <0.61,P > 0.05). TAPSE performed marginally better with an AUROCC of 0.65 (P = 0.04). RV-GPLS and RV-FWPLS demonstrated good predictive ability with AUROCC’s of 0.74 and 0.76 respectively (P < 0.01 for both). This study demonstrates that the conventional TTE parameters of RV systolic function are inadequate following lung resection. Longitudinal strain performs better and offers some ability to determine poor RV function in this challenging population.

Abstract Background In approximately 30-40% of cases, the left ventricular systolic function does not improve following cardiac resynchronization therapy (CRT; non-responders). Currently, the role of right ventricular (RV) systolic function is not yet completely clear in the background. Our aim was to assess the RV systolic function with 3D echocardiography in CRT patients. Methods We selected 19 patients who received CRT in our department between May and June 2017, and whose 1-year follow-up data were available. We characterized several 2D parameters of RV systolic function, such as RV free wall strain (RV GLSFW), annular s’ wave velocity (TDI s), tricuspid annulus plane systolic excursion (TAPSE), RV fractional area change (RV FAC). A number of 3D parameters were also assessed, such as RV ejection fraction (EF), end-diastolic (EDV) and end-systolic (ESV) volumes, using a dedicated RV analysis software. Moreover, we measured the LV EF and considered the patients "responder", when the LV EF improved with at least 10% after CRT implantation. Results From 19 patients, 12 was identified as responders (R) and 7 as non-responders (NR). No significant difference was seen in the mean age of patients in the two groups (NR: 68 ± 6 year; R: 67 ± 9 year, p = 0.76), however, the proportion of male individuals was higher in the NR group (8/12 vs. 1/7). The RV EF was higher in the R group (41 ± 8% vs.29 ± 10%; p = 0.012), while the EDV or ESV did not differ between the two groups. The RV GLSFW (–21.2 ± 7% vs.–13.9 ± 7%, p = 0.045) and the TAPSE (16.8 ± 5 mm vs.11.4 ± 3 mm, P = 0.03) values were significantly different between the two groups. Based on logistic regression analysis, the RV EF was an independent predictor of non-respondence. Conclusions The lower RV EF indicates non-respondence to CRT, however, it is not associated with RV dilation, i.e.adverse remodelling. These results suggest mechanical abnormality of RV function in the background of impaired EF.

Abstract Background Assessment of the right ventricle (RV) in heart failure (HF) is challenging and requires applicable methods and parameters. Atrial fibrillation (AF) is a common and clinically significant arrhythmia in 30–50% of HF patients. Assessment of the RV function in patients with AF is problematic. Still little is known about RV function in HF and AF patients. The aim of the study was to assess RV function in HF with focus on AF patients. Methods Patients with HF of ischemic etiology, NYHA II-III, LVEF ≤40%, with AF and sinus rhythm (SR), underwent two- and three- dimensional echocardiography (2DE and 3DE) for assessment of the RV with use of multiple parameters. The RV was examined for: linear dimensions, end-diastolic and end-systolic areas adjusted to body surface area (RV EDA and RV ESA/BSA) and end-diastolic and end-systolic volumes adjusted to lean body mass (RV EDV and RV ESV/LBM) to reflect volume overload and in terms of right ventricular pressure (RVSP) as an index of pressure overload. RV systolic function was assessed with 2DE: tricuspid annular plane systolic excursion (TAPSE), right ventricular fractional area change (RV FAC), tricuspid lateral annular systolic velocity (s') and 3DE parameters: right ventricular ejection fraction (RVEF) and free wall right ventricular longitudinal strain (FW RVLS). Also, TAPSE/RVSP parameter was included. Results The study included 126 patients: 94 with AF and 32 with SR. Within the AF group 28 patients were treated medically, 41 had RV pacing (pacemaker or an implantable cardioverter-defibrillator, ICD) and 25 had cardiac resynchronisation therapy (CRT). In comparison with SR group AF patients had: larger RV inflow tract dimension (4.49±0.85 vs. 3.95±0.72 cm; p=0.0017), RV EDA/BSA (12.7±3.9 vs. 11.1±3.0 cm2/m2; p=0.0358) and RV ESA/BSA (8.0±3.0 vs. 6.7±2.4 cm2/m2; p=0.0226). Similarly, patients with AF had greater RV volumes in 3DE than patients with SR: RV EDV/LBM (1.82±0.60 vs. 1.61±0.38ml/kg, p=0.0267) and RV ESV/LBM (1.11±0.40 ml/kg vs. 0.81±0.28, p<0,0001). Also, in patients with AF right ventricular systolic pressure (RVSP) was higher (40.8±10.2 vs. 34.0±8.1 mmHg, p=0,0010). No differences in TAPSE and RVFAC were found but the relation TAPSE/RVSP was higher in AF than in SR group (0.51±0.21 vs. 0.65±0.24 cm/mmHg; p=0.0046). Also, in AF patients in comparison to SR group some parameters had worse values: s' (9.7±2.31 vs. 12.1±3.83, p=0.014), RVEF (37.2±7.3 vs. 48.2±7.5, p<0.0001 and FW RVLS (−18.3±4.6 vs. −23.9±4.23%, p<0,0001). Within the AF group no significant differences in studied variables depending on RV pacing or CRT were found. Conclusions Larger volumes and higher pressure overload of the RV were observed in patients with AF in comparison to SR. Systolic function of the RV seems to be more depressed in AF compared to SR patients with systolic heart failure. Further research in larger groups is required to identify the most applicable and valuable methods of RV evaluation.

Abstract Background Right ventricular (RV) function is recognized as a prognostic factor in congenital heart disease (CHD). Accurate echocardiographic parameters to assess systolic function in systemic RV (sRV) lacking. We previously introduced a novel four-view approach with different RV walls visualized in their long axis from one apical view using 2D-multi-plane transthoracic echocardiographic (TTE) (iRotate). Aims To extensively evaluate RV systolic function using iRotate echocardiography in CHD patients with systemic RV compared with a whole spectrum of CHD patients with abnormally loaded subpulmonic RV. Methods and Results Thirty CHD patients with sRV and 112 age, gender and BSA matched patients with abnormally loaded subpulmonic RV were recruited from the outpatient clinic. All subjects underwent complete TTE with evaluation of TAPSE, TDI S’ and peak systolic global longitudinal RV strain (RV-GLS) from the RV walls using the four-view iRotate model. The feasibility of TAPSE and TDI S’ ranged between 94% and 100%. The feasibility of RV-GLS in CHD was 98%, 69%, 87% and 72% respectively in the lateral, anterior, inferior and inferior coronal view walls. All echocardiographic parameters were significantly lower in sRV compared to versus subpulmonic RV cohort (p &lt; 0.001) (Table). Conclusion This study provides for the first time an extensive RV specific analysis of the systemic RV. The feasibility of all RV parameters in the four-view iRotate model is excellent in CHD and represents a reproducible, easily applicable and complete RV assessment in daily practice. Systolic function is significantly reduced in systemic RV compared to subpulmonic RV physiology. Abstract P990 Figure.
