BACKGROUND Direct comparisons of combined (C-ABL) and non-combined (NC-ABL) endo-epicardial ventricular tachycardia (VT) ablation outcomes are scarce. We aimed to investigate the long-term clinical efficacy and safety of these 2 strategies in ischemic heart disease (IHD) and nonischemic cardiomyopathy (NICM) patients. METHODS Multicentric observational registry including 316 consecutive patients who underwent catheter ablation for drug-resistant VT between January 2008 and July 2019. Primary and secondary efficacy endpoints were defined as VT-free survival and all-cause death after ablation. Safety outcomes were defined by 30-days mortality and procedure-related complications. RESULTS Most of the patients were male (85%), with IHD (67%) and mean age of 63±13 years. During a mean follow-up of 3±2 years, 117 (37%) patients had VT recurrence and 73 (23%) died. Multivariate survival analysis identified electrical storm (ES) at presentation, IHD, left ventricular ejection fraction (LVEF), New York Heart Association (NYHA) class III/IV, and C-ABL as independent predictors of VT recurrence. In 135 patients undergoing repeated procedures, only C-ABL and ES were independent predictors of relapse. The independent predictors of mortality were C-ABL, ES, LVEF, age and NYHA class III/IV. C-ABL survival benefit was only seen in patients with a previous ablation (P for interaction=0.04). Mortality at 30-days was similar between NC-ABL and C-ABL (4% vs. 2%, respectively, P=0.777), as was complication rate (10.3% vs. 15.1% respectively, P=0.336). CONCLUSION A combined endo-epicardial approach was associated with greater VT-free survival and lower all-cause death in IHD and NICM patients undergoing repeated VT catheter ablations. Both strategies seem equally safe.

Abstract Aims Hypertrophic cardiomyopathy (HCM) is an inheritable disease that leads to sudden cardiac death and heart failure (HF). Sarcomere mutations (SMs) have been associated with HF. However, the differences in ventricular function between SM-positive and SM-negative HCM patients are poorly characterized. Methods and results  Of the prospectively enrolled 374 unrelated HCM patients in Taiwan, 115 patients underwent both 91 cardiomyopathy-related gene screening and cardiovascular magnetic resonance (45.6 ± 10.6 years old, 76.5% were male). Forty pathogenic/likely pathogenic mutations were identified in 52 patients by next-generation sequencing. The SM-positive group were younger at first cardiovascular event (P = 0.04) and progression to diastolic HF (P = 0.02) with higher N-terminal pro-brain natriuretic peptide (NT-proBNP) [New York Heart Association (NYHA) Class III/IV symptoms with left ventricular ejection fraction > 55%] than the SM-negative group (P < 0.001). SM-positive patients had a greater extent of late gadolinium enhancement (P = 0.01), larger left atrial diameter (P = 0.03), higher normalized peak filling rate (PFR) and PFR ratio, and a greater reduction in global longitudinal strain than SM-negative patients (all P ≤ 0.01). During mean lifelong follow-up time (49.2 ± 15.6 years), SM-positive was a predictor of earlier HF (NYHA Class III/IV symptoms) after multivariate adjustment (hazard ratio 3.5; 95% confidence interval 1.3–9.7; P = 0.015). Conclusion SM-positive HCM patients had a higher extent of myocardial fibrosis and more severe ventricular diastolic dysfunction than those without, which may contribute to earlier onset of advanced HF, suggesting the importance of close surveillance and early treatment throughout life.

Abstract Introduction Direct comparisons of long-term clinical outcomes of endocardial vs. epicardial catheter ablation techniques for drug-resistant ventricular tachycardia (VT) have been scarcely reported. We aim to compare the long-term efficacy and safety of endocardial vs. epicardial catheter ablation (END-ABL and EPI-ABL, respectively) in a propensity score (PS) matched population. Methods Single-center observational registry including 215 consecutive patients who underwent END-ABL (181) or EPI-ABL (n=34) for drug-resistant VT between January 2007 and June 2018. Efficacy endpoint was defined as VT-free survival after catheter ablation, while safety outcomes were defined by 30-days mortality and procedure-related complications. A propensity score was used to match patients in a 1:1 fashion according to the following variables: VT storm at presentation, left ventricular ejection fraction (LVEF), New York Heart Association (NYHA) class III/IV at presentation, ischemic ethology, presence of implantable cardioverter-defibrillator (ICD), and previous endocardial catheter ablation. Independent predictors of VT recurrence were assessed by Cox regression. Results The PS yielded two groups of 31 patients each well matched for baseline characteristics (Table 1). Over a median follow-up of 2 years (IQR 1–3), 58% (n=18) ENDO-ABL patients had VT recurrence vs. 26% (n=8) in the EPI-ABL group (P=0.020). The yearly rates of VT recurrence were 28%/year for END-ABL vs. 11%/year for EPI-ABL (P=0.021). Multivariate survival analysis identified previous endocardial ablation (HR= 3.52; 95% CI 1.17–10.54, p=0.026) and VT storm at presentation (HR=3.57; 95% CI 1.50–8.50, p=0.004) as independent predictors of VT recurrence. EPI-ABL was independently associated with fewer VT recurrences (HR=0.28; 95 CI 0.12–0.69, p=0.005), but only in patients with a previous endocardial ablation (p for interaction = 0.004) – Figure A. No patients died at 30-days post-procedure. Hospital length of stay was similar between END-ABL and EPI-ABL (5 vs. 4 days respectively, p=0.139), as was the complication rate (6.5% vs. 12.9% respectively, p=0.390), although driven by different causes (Table 1). Conclusion VT storm at presentation and previous catheter ablation were independent predictors of VT recurrence. In patients with a previous failed endocardial catheter ablation, epicardial ablation seems to provide greater VT-free survival than repeat endocardial ablation. Both strategies seem equally safe.

Abstract Background Patients with ischemic (IHD) and nonischemic (NICM) dilated heart disease and reduced left ventricular ejection fraction are at increased risk of ventricular tachycardias (VTs) or sudden cardiac death. VT catheter ablation is an invasive treatment modality for antiarrhythmic drugs-resistant VT that reduces arrhythmic episodes, improves quality of life and improves survival in patients with electrical storm. Direct comparison of the outcomes from combined and non-combined endoepicardial ablations is limited by patient characteristics, follow-up durations, protocols heterogeneity and scarcity of randomized trials. We aim to investigate the long-term clinical outcomes of these 2 strategies in the IHD and NICM populations. Methods Multicentric observational registry including 316 consecutive patients who underwent combined (C-ABL) and non-combined (NC-ABL) endoepicardial ventricular tachycardia (VT) ablation for drug-resistant VT between January 2008 and July 2019. Chagas' disease patients were excluded. Primary and secondary efficacy endpoints were defined as VT-free survival and all-cause death after ablation. Safety outcomes were defined by 30-days mortality and procedure-related complications. Results Most of the patients were male (85%), with IHD (67%) and a mean age of 63±13 years. During a mean follow-up of 3±2 years, 117 (37%) patients had VT recurrence and 73 (23%) died. Multivariate survival analysis identified storm (ES) at presentation (HR=2.17; 95% CI 1.44–3.25), IHD (HR=0.53, 95% CI 0.36–0.78), left ventricular ejection fraction (LEVF) (HR=0.97, 95% CI 0.95–0.99), New York Heart Association (NYHA) functional class III or IV (HR=1.79, 95% CI 1.13–2.85) and C-ABL (HR=0.49, 95% CI 0.27–0.92) as independent predictors of VT recurrence. In 135 patients undergoing two or more ablation procedures only C-ABL (HR=0.36, 95% CI 0.17–0.80) and ES at presentation (HR=2.42, 95% CI 1.24–4.70) were independent predictors of arrhythmia recurrence. The independent predictors of all-cause mortality were ES (HR=2.17, 95% CI 1.33–3.54), LVEF (HR=0.95, 95% CI 0.92–0.98), age (HR=1.03, 95% CI 1.01–1.05), NYHA functional class III or IV (HR=2.04, 95% CI 1.12–3.73), and C-ABL (HR=0.22, 95% CI 0.05–0.91). The survival benefit was only seen in patients with a previous ablation (P for interaction=0.04) – Figure 1. Mortality at 30-days was similar between NC-ABL and C-ABL (4% vs. 2%, respectively, P=0.777), as was the complication rate (10.3% vs. 15.1% respectively, P=0.336). Conclusion A combined endo-epicardial approach appears to be associated with greater VT-free survival and overall survival in ischemic and nonischemic patients undergoing repeated VT catheter ablations.

Abstract Funding Acknowledgements Type of funding sources: None. Background HeartMate3TM (HM3) is a relatively new left ventricular assist device (LVAD) system. Its design and magnetically levitated pump may impact VTA. Objectives To describe clinical characteristics, procedural details, specific challenges and outcomes in patients with HM3 referred for ventricular tachycardia ablation (VTA). Methods Data was collected from patients implanted with an HM3 system who underwent VTA in 7 tertiary centers. Data included baseline patient characteristics, procedural data, mortality, and arrhythmia-free survival. Results  The study cohort included 19 patients (18 male, aged 65 ± 7.8 years) with low left ventricular ejection fraction (LVEF, 17 ± 5%), presenting with VT (53% with storm VT).  VTs were induced in 89% of patients and a total of 41 VTs were observed.  Severe electromagnetic interference was present in the surface ECG (Figure A) but not on endocardial electrograms (Figure B). Hence, VT localization required analysis of intra-cardiac signals or the use of filter in the 40-20 Hz range. A total of 32 VTs were mapped and were successfully ablated (31% to the anterior wall, 38% to the septum, and only 9% to the inflow cannula region).  Notably, the large pump housing tends to obscure clear visualization of the apical region in fluoroscopy particularly in the LAO view (Figure C,D). Therefore, three-dimensional electro-anatomical mapping was aided by ICE or CARTOSound in 71% cases (Figure E). Non-inducibility of any VT was reached in 11 patients (58%). Over a follow up of 429 (IQR 101-692) days, 5 (26%) patients underwent a redo VT ablation due to recurrent VTA and 2 (11%) patients died. Conclusions VT ablation in patients with HM3 is feasible and safe when done in the appropriate setup. Long-term arrhythmia free survival is acceptable but not well predicted by non-inducibility at the end of the procedure. Abstract Figure. HeartMate3 ablation Challenges

Abstract Funding Acknowledgements Type of funding sources: None. INTRODUCTION Catheter ablation outcomes for drug-resistant ventricular tachycardia (VT) in nonischemic cardiomyopathy (NICM) are suboptimal when compared to ischemic cardiomyopathy. We aimed to analyse the long-term efficacy and safety of percutaneous catheter ablation in this subset of patients. METHODS Single-center observational retrospective registry including consecutive NICM patients who underwent catheter ablation for drug-resistant VT during a 10-year period. The efficacy endpoint was defined as VT-free survival after catheter ablation, while safety outcomes were defined by 30-days mortality and procedure-related complications. Independent predictors of VT recurrence were assessed by Cox regression. RESULTS In a population of 68 patients, most were male (85%), mean left ventricular ejection fraction (LVEF) was 34 ± 12%, and mean age was 58 ± 15 years. All patients had an implantable cardioverter-defibrillator. Twenty-six (38%) patients underwent epicardial ablation (table 1). Over a median follow-up of 3 years (IQR 1-8), 41% (n = 31) patients had VT recurrence and 28% died (n = 19). Multivariate survival analysis identified LVEF (HR= 0.98; 95%CI 0.92-0.99, p = 0.046) and VT storm at presentation (HR = 2.38; 95%CI 1.04-5.46, p = 0.041) as independent predictors of VT recurrence. The yearly rates of VT recurrence and overall mortality were 21%/year and 10%/year, respectively. No patients died at 30-days post-procedure, and mean hospital length of stay was 5 ± 6 days. The complication rate was 7% (n = 5, table 1), mostly in patients undergoing epicardial ablation (4 vs 1 in endocardial ablation, P = 0.046). CONCLUSION LVEF and VT storm at presentation were independent predictors of VT recurrence in NICM patients after catheter ablation. While clinical outcomes can be improved with further technical and scientific development, a tailored endocardial/epicardial approach was safe, with low overall number of complications and no 30-days mortality.

Abstract PurposeTrastuzumab improves survival in patients with HER2+ early breast cancer. However, cardiotoxicity remains a concern, particularly in the curative setting, and there are limited data on its incidence outside of clinical trials. We retrospectively evaluated the cardiotoxicity rates (left ventricular ejection fraction [LVEF] decline, congestive heart failure [CHF], cardiac death or trastuzumab discontinuation) and assessed the performance of a proposed model to predict cardiotoxicity in routine clinical practice.MethodsPatients receiving curative trastuzumab between 2011-2018 were identified. Demographics, treatments, assessments and toxicities were recorded. Fisher’s exact test, chi-squared and logistic regression were used.Results931 patients were included in the analysis. Median age was 54 years (range 24-83) and Charlson comorbidity index 0 (0-6), with 195 patients (20.9%) aged 65 or older. 228 (24.5%) were smokers. Anthracyclines were given in 608 (65.3%). Median number of trastuzumab doses was 18 (1-18). The HFA-ICOS cardiovascular risk was low in 401 patients (43.1%), medium in 454 (48.8%), high in 70 (7.5%) and very high in 6 (0.6%).Overall, 155 (16.6%) patients experienced cardiotoxicity: LVEF decline≥10% in 141 (15.1%), falling below 50% in 55 (5.9%), CHF NYHA class II in 42 (4.5%) and class III-IV in 5 (0.5%) and discontinuation due to cardiac reasons in 35 (3.8%). No deaths were observed.Cardiotoxicity rates increased with HFA-ICOS score (14.0% low, 16.7% medium, 30.3% high/very high; p=0.002). ConclusionsCardiotoxicity was relatively common (16.6%), but symptomatic heart failure on trastuzumab was rare in our cohort. The HFA-ICOS score identifies patients at high risk of cardiotoxicity

517 Background: M in combination with T has shown promising activity and cardiac safety in MBC patients (pts). We conducted a randomized Phase III trial of first-line M plus T and P (MTP) versus T plus P (TP) in HER2+ MBC pts. Methods: Pts with HER2+ (by FISH) MBC ≥ 18 years and ECOG 0-1, who had received no prior chemotherapy for metastatic disease, were eligible. Left ventricular ejection fraction should be within normal institutional limits. Prior (neo-) adjuvant anthracyclines, T or P were permitted, if completed >1 year before the start of the study. Pts received M 50 mg/m2 q3w for 6 cycles, T 4 mg/kg loading dose followed by 2 mg/kg qw, and P 80 mg/m2qw, or T+P at the same doses until progression or toxicity. Primary outcome was progression-free survival (PFS). Enrollment of 332 pts would provide 80% power with a 5% significance to detect an improvement in PFS with MTP, assuming a median PFS of 8 months in TP and a hazard ratio (HR) of 0.70. Results: 363 pts enrolled (MTP 181, TP 183), 360 received treatment. The two groups were well balanced for demographics, pretreatment characteristics and extent of disease. One third of the pts had prior exposure to anthracyclines, but almost none to trastuzumab (1% and 2% in MTP and TP arms, respectively). Six cycles of M could be given to 72% of the pts. With a median follow-up of 31 months, median PFS was 16.1 and 14.5 months with MTP and TP, respectively (HR 0.84, P=0.174). In pts with ER and PR-negative tumors, PFS was 20.7 and 14.0 months, respectively (HR, 0.68; 95% CI 0.47–0.99). Median overall survival (OS) was 33.6 and 28.9 months, respectively (HR, 0.79, P=0.083). In ER and PR-negative tumors, OS was 38.2 and 27.9 months, respectively (HR, 0.63; 95% CI 0.42–0.93). The incidence of NYHA Class III/IV congestive heart failure was 3% with MTP and there were 2 cardiac deaths with TP. The frequency of adverse events was higher with MTP, especially myelosuppression, stomatitis and gastrointestinal intolerance. Conclusions: The trial failed to demonstrate a significant clinical improvement with the addition of M to TP. The clinical benefit observed in an exploratory analysis in the ER and PR-negative population deserves consideration for further clinical trials. Clinical trial information: NCT00294996.

Abstract Aims Diuretics in heart failure (HF) are commended to relieve symptoms at lowest dosage effective. Dilated cardiomyopathy (DCM) is a particular HF setting with several variables that may influence disease trajectory. We aimed to assess the long-term use of diuretics in DCM, the possibility of withdrawal and to explore the prognostic correlations. Methods and results All consecutive DCM patients enrolled from 1990 to 2018 were considered eligible. All the patients had available the information about the furosemide-equivalent dose at baseline and at follow-up evaluation within 24 months. Patients were categorized in stable (diuretic dose variation <50%), increasers (diuretics dose increase ≥50% or initiation of diuretic therapy), and decreasers (diuretics dose decrease ≥50% or never prescribed diuretics in the 24-months observation period). The prognostic role of the diuretics trajectory group was assessed with Kaplan Meier analysis and with a time-dependent multivariable model. The outcome measure was a composite of all-cause death/heart transplantation/HF hospitalization (ACD/HTx/HFH). 908 patients were included [mean age 50 ± 16, 70% male sex, 24% NYHA class III or IV, mean left ventricular ejection fraction (LVEF) 31 ± 9%, 66% treated with diuretics at baseline]. The furosemide-equivalent dose at enrolment had a linear association with the risk of outcome. Compared to other groups, decreaser patients were younger, had less HF symptoms, higher LVEF and more dilated left atrium. Decreasers had a lower prescription rate of diuretics and less frequent indication to renin-angiotensin inhibitors and mineralocorticoid receptors antagonists. Over a median follow-up of 122 (62–195) months decreasers had the lowest incidence of outcome, followed by stable, while increasers had the worst outcome (P < 0.001). After adjustment for other prognosticators, compared to stable patients, decreasers had a reduced risk of ACD/HTx/HFH [HR: 0.497 (95% CI: 0.337–0.731)] while increasers had the highest risk of adverse outcome [HR: 2.027 (95% CI: 1.254–3.276)]. Similarly, amongst patients taking diuretics at baseline, the diuretics withdrawal was in independent outcome predictor. The only multivariable predictors of diuretics withdrawal were younger age and lower furosemide-equivalent dose at enrolment. Conclusions In DCM patients the diuretics dose at baseline is a strong prognosticator. Diuretics dose reduction or its withdrawal provides a prognostic benefit on hard outcome. Diuretics tapering in selected patients should be considered in the short-term follow-up to improve DCM prognosis.

Abstract Background Arterial stiffness is strongly linked to the pathogenesis of heart failure and the development of acute decompensation in patients with stable chronic heart failure. This study aimed to compare arterial stiffness indices in patients with heart failure with reduced ejection fraction (HFrEF) during the acute decompensated state, and three months later after hospital discharge during the compensated state. Results One hundred patients with acute decompensated HFrEF (NYHA class III and IV) and left ventricular ejection fraction ≤ 35% were included in the study. During the initial and follow-up visits, all patients underwent full medical history taking, clinical examination, transthoracic echocardiography, and non-invasive pulse wave analysis by the Mobil-O-Graph 24-h device for measurement of arterial stiffness. The mean age was 51.6 ± 6.1 years and 80% of the participants were males. There was a significant reduction of the central arterial stiffness indices in patients with HFrEF during the compensated state compared to the decompensated state. During the decompensated state, patients presented with NYHA FC IV (n = 64) showed higher AI (24.5 ± 10.0 vs. 16.8 ± 8.6, p < 0.001) and pulse wave velocity (9.2 ± 1.3 vs. 8.5 ± 1.2, p = 0.021) than patients with NYHA FC III, and despite the relatively smaller number of females, they showed higher stiffness indices than males. Conclusions Central arterial stiffness indices in patients with HFrEF were significantly lower in the compensated state than in the decompensated state. Patients with NYHA FC IV and female patients showed higher stiffness indices in their decompensated state of heart failure.

ObjectivesN-terminal probrain natriuretic peptide (NT-proBNP) predicts mortality and the development of heart failure in hypertrophic cardiomyopathy (HCM). Mid-regional proatrial natriuretic peptide (MR-proANP) is a stable by-product of production of atrial natriuretic peptide. We sought to compare the prognostic value of MR-proANP and NT-proBNP in HCM.MethodsWe prospectively enrolled a cohort of patients with HCM from different European centres and followed them. All patients had clinical, ECG and echocardiographic evaluation and measurement of MR-proANP and NT-proBNP at inclusion.ResultsOf 357 patients enrolled, the median age was 52 (IQR: 36–65) years. MR-proANP and NT-proBNP were both independently associated with age, weight, New York Heart Association (NYHA) class, left ventricular ejection fraction (LVEF), wall thickness and left atrial dimension. During a median follow-up of 23 months, 32 patients had a primary end point defined as death (n=6), heart transplantation (n=8), left ventricular assist device implantation (n=1) or heart failure hospitalisation (n=17). Both NT-proBNP and MR-proANP (p<10–4) were strongly associated with the primary endpoint, and the areas under the receiver operating characteristic (ROC) curves for both peptides were not significantly different. However, in a multiple stepwise regression analysis, the best model for predicting outcome was NYHA 1–2 vs 3–4 (HR=0.35, 95% CI 0.16 to 0.77, p<0.01), LVEF (HR=0.96, 95% CI 0.94 to 0.98, p=0.0005) and MR-proANP (HR=3.77, 95% CI 2.01 to 7.08, p<0.0001).ConclusionsMR-proANP emerges as a valuable biomarker for the prediction of death and heart failure related events in patients with HCM.
