Introduction: New permanent pacemaker (PPM) requirement has been linked with left ventricular dysfunction after TAVR. Objective: We sought to study the impact of new PPM on echocardiographic outcomes after TAVR with SAPIEN-3 (S3) valve. Methods: We included consecutive patients who underwent TAVR with S3 valve at the Cleveland Clinic between April 2015 and December 2018. Patients with prior PPM were excluded. Echocardiograms were reviewed to determine left ventricular ejection fraction (LVEF), left ventricular end diastolic volume index (LVEDVi), left ventricular end systolic volume index (LVESVi), left ventricular dimension during diastole (LVDd), posterior wall thickness during diastole (PWTd), interventricular septum during diastole (IVSd), right ventricular systolic pressure (RVSP), inferior vena cava (IVC) diameter and tricuspid regurgitation (TR) grade. Results: Among 886 patients, the rate of 30-day PPM was 10.2%. Baseline LVEF was similar between new PPM and no PPM (55.4 ± 12.7% vs. 57.2 ± 11.2%; p = 0.188). There were no differences in the other studied echocardiographic parameters at baseline. Among patients with new PPM, LVEF was lower at both 30 days (54.4 ± 11.3% vs. 58.4 ± 10.1%; p = 0.001) and 1 year (54.2 ± 12% vs. 59.1 ± 11.3%; p = 0.009) compared to no PPM with Δ LVEF -0.9% vs. +1.4%; p = 0.023. There were no differences in LVEDVi (52 ± 20.8 vs. 48.3 ± 17.6; p = 0.186) at 1 year. LVESVi was higher with new PPM (24.8 ± 16.1 vs. 20.2 ± 10.9; p = 0.038). However, Δ LVESVi was similar between the 2 groups (-1.6 vs. -2.6; p = 0.517). There were no differences in RVSP (38.9 ± 14.1 vs. 40 ± 14; p = 0.58). LVIDd, PWTd, IVSd and IVC diameter also did not show variations whether patients were paced or not. Moderate to severe TR rates were similar as well (17.7% vs. 21.5%; p = 0.407). Conclusion: Among S3 TAVR recipients, new pacing requirement had a detrimental impact on LVEF at both 30 days and 1 year. However, it did not seem to affect the other studied echocardiographic outcomes after TAVR.

Abstract Background New left bundle branch block (LBBB) is a common finding after transcatheter aortic valve replacement (TAVR) that can result in worse outcomes after TAVR. We aim to investigate the impact of new-onset LBBB after TAVR using the SAPIEN-3 (S3) valve. Methods Consecutive patients who underwent transfemoral-TAVR with S3 valve between April 2015 and December 2018 were included. Exclusion criteria included pre-existing LBBB, right bundle branch block, left anterior hemiblock, left posterior hemiblock, wide QRS ≥120 msec, prior permanent pacemaker (PPM), and non-transfemoral access. Results Among 612 patients, 11.4% developed new-onset LBBB upon discharge. Implantation depth was the only predictor of new-onset LBBB (OR 1.294; 95% CI 1.121–1.493; p<0.001). The median (IQR) length of stay was longer with new-onset LBBB [3 (2–5) days vs. 2 (1–3) days; p<0.001]. New-onset LBBB was associated with higher thirty-day PPM requirement (18.6% vs. 5.4%; p<0.001) including those implanted after discharge (4.3% vs. 0.9%; p=0.02). There was no difference in 3-year all-cause mortality between both groups (30.9% vs. 30.6%; log-rank p=0.829). Further, new-onset LBBB was associated with lower left ventricular ejection fraction (LVEF) at both 30 days (55.9±11.4% vs. 59.3±9%; p=0.026) and 1 year (55±12% vs. 60.1±8.9%; p=0.002) despite no differences at baseline. These changes were still present when we stratified patients according to baseline LVEF (≥50% or <50%). We also noted higher mean LV end-diastolic volume index (51.4±18.6 vs. 46.4±15.1 ml/m2; p=0.036), and LV end-systolic volume index (23.2±14.1 vs. 18.9±9.7 ml/m2; p=0.009) with new-onset LBBB at 1 year. Lastly, there were significantly higher rates of heart failure readmissions at 1 year with new-onset LBBB (10.7% vs. 4.4%; log-rank p=0.033). Conclusion Among our cohort of S3 recipients, new-onset LBBB was associated with higher PPM requirement, worse LVEF, higher LV volumes and increased risk of heart failure hospitalizations. However, it did not affect mortality in the short-to-intermediate post-TAVR period. FUNDunding Acknowledgement Type of funding sources: None. Figure 1. All-cause Survival

Abstract INTRODUCTION Subaortic membrane is an entity which evolves during adulthood and can associate cardiac complications. Different morphologies have been described, although it is unknown if their prognosis varies according to these patterns. The aim of this study was to evaluate the cardiac prognosis of patients with subaortic membrane according to their morphological characteristics in adulthood. METHODS Forty-five patients diagnosed with subaortic membrane by imaging techniques were consecutively included (March 1999-August 2018). Three morphologies were described: fibromuscular ridge (FR), crescent-shaped (CS) and filamentous-shaped (FS). Cardiac complications were defined as mortality due to heart failure and/or necessity of aortic valve surgery and/or membrane resection. RESULTS Twenty-six cases (58%) had FR, 16 (35%) had CS and 3 (7%) presented FS (7%) (Fig.1). No differences were found in basal clinical parameters between groups. FR type was associated with the presence of dynamic gradient in baseline study (27% vs 0%, p = 0.014), but there were no differences in left ventricular ejection fraction (68 ± 8% vs 64 ± 8%; p = 0.092), nor in maximum thickness of basal interventricular septum (12.1 ± 3.9mm vs 11.7 ± 4.1mm, p = 0.699), nor in the presence of moderate/severe aortic stenosis (15% vs 11%, p > 0.999) with the other morphologies. During follow-up (mean ± SD= 5.8 ± 4.4years) 15 (33%) patients presented cardiac complications (2 deaths due to heart failure and 12 valvular interventions and/or membrane resection). FR type patients presented a higher cardiac complication rate (50% vs 11%, p = 0.006) and greater necessity of open-heart surgery (46% vs 11%, p = 0.011) than the other groups during follow-up. CONCLUSIONS FR type is associated with a higher rate of cardiac complications during follow-up than other subaortic membrane morphologies. Dynamic gradient associated to this pattern could be the basis of a possible pathophysiological mechanism related to the worst prognosis of these patients. Figure 1.

Abstract Background Percutaneous left atrial (LA) appendage closure is increasingly used to prevent strokes in patients with atrial fibrillation (AF). While LA appendage plays a key role in LA physiology, data regarding the impact of LA appendage occlusion on LA hemodynamics are lacking. The alteration of LA compliance by LA appendage occlusion may represent a clinical issue in AF patients which are at high risk of heart failure. Purpose To describe the impact of LA appendage occlusion on LA hemodynamics. Material and methods From july 2015 to january 2020, all patients undergoing LA occlusion procedure at Pitié-Salpêtrière Hospital (Paris, France) in whom LA pressure curves were recorded, before and immediately after device implantation, were included. The LA mean pressure was measured at baseline and after LA appendage occlusion during the same procedure. Abnormal LA mean pressure was defined as >15mmHg. We also recorded cardiovascular death and hospitalization for congestive heart failure at longest follow-up. Results We enrolled 85 patients (78±8 years, 46 men), the CHA2DS2-VASc score was 5±1 and the HAS-BLED score was 4±1. The mean LA volume index was 51±15mL/m2, the left ventricular ejection fraction was 60±7%. The LA mean pressure increased significatively after LA appendage closure from 12.6±3.9mmHg to 15.5±5.2mmHg (p<0.0001, Figure). The prevalence of abnormal LA pressure was 20% (17/85) at baseline and 45% (38/85) after LA appendage closure (p=0.005). Post procedural LA pressure elevation was not related to procedure duration nor to fluid expansion volume. During a median follow-up of 364 [124–726] days, 3 (3.5%) patients died from a cardiovascular cause. Hospitalization for heart failure occurred in 6 (16%) of the 38 patients with abnormal postprocedural LA pressure, whereas no congestive episode was observed in the rest of the study population (p=0.006). Conclusion Catheter-based LA appendage occlusion induces an acute alteration of LA hemodynamics. Post procedural abnormal LA pressure may be linked to heart failure episodes in some patients. Further studies are warranted to investigate heart failure as a potential late complication of LA appendage closure.

Abstract Background Aortic regurgitation (AR) is a common comorbidity in patients with aortic stenosis (AS), but co-existing AR has often been an exclusion criterion from major clinical trials. The impact of co-existing AR on the natural history of AS has not been well-described. Purpose We compared clinical outcomes in patients with moderate to severe AS with or without co-existing AR. Methods Consecutive patients (n=1188) with index echocardiographic diagnosis of moderate to severe AS (AVA <1.5cm2) were studied. They were divided into those with co-existing AR (at least moderate severity) and those without. Adverse composite clinical outcomes were defined as either mortality or admissions for congestive cardiac failure on subsequent follow-up for at least five years. Appropriate univariate and multivariable analyses were employed to compare the two groups. Results There were 88 patients (7.4%) with co-existing AR and AS. These patients did not differ significantly in age, but had lower body mass index (22.9±3.8 vs 25.3±5.1 kg/m2). They also had lower diastolic blood pressure (68.7±10.7 vs 72.2±12.3 mmHg), larger end-diastolic volume index (68.8±18.8 vs 60.4±17.8 ml/m2) and left ventricular mass index (118.6±36.4 vs 108.9±33.1 g/m2). The prevalence of cardiovascular risk factors did not differ significantly between the groups. Co-existing AR was associated with adverse outcomes (log-rank 4.20, p=0.040). On multivariable Cox-regression, co-existing AR remained independently associated with adverse outcomes (hazard ratio 1.51, 95% CI 1.13–2.02) after adjusting for age, AS severity and left ventricular ejection fraction. Conclusion In patients with AS, co-existing AR was associated with a distinct echocardiographic profile and adverse outcomes. Funding Acknowledgement Type of funding source: None

Background: In this paper, we propose a new efficient method of radionuclide ventriculography image segmentation to estimate the left ventricular ejection fraction. This parameter is an important prognostic factor for diagnosing abnormal cardiac function. Methods: The proposed method combines the Chan-Vese and the mathematical morphology algorithms. It was applied to diastolic and systolic images obtained from the Nuclear Medicine Department of Salah AZAIEZ Institute.In order to validate our proposed method, we compare the obtained results to those of two methods of the literature. The first one is based on mathematical morphology, while the second one uses the basic Chan-Vese algorithm. To evaluate the quality of segmentation, we compute accuracy, positive predictive value and area under the ROC curve. We also compare the left ventricle ejection fraction estimated by our method to that of the reference given by the software of the gamma-camera and validated by the expert, using Pearson’s correlation coefficient, ANOVA test and linear regression. Results and conclusion: Static results show that the proposed method is very efficient in the detection of the left ventricle. The accuracy was 98.60%, higher than that of the other two methods (95.52% and 98.50%). Likewise, the positive predictive value was the highest (86.40% vs. 83.63% 71.82%). The area under the ROC curve was also the most important (0.998% vs. 0.926% 0.919%). On the other hand, Pearson's correlation coefficient was the highest (99% vs. 98% 37%). The correlation was significantly positive (p<0.001).

Abstract Background Heart failure (HF) is a major and growing medical and economic problem, with high prevalence and incidence rates worldwide. Cardiac Biomarker is emerging as a novel tool for improving management of patients with HF with a reduced left ventricular ejection fraction (HFrEF). Methods This is a before and after interventional study, that assesses the impact of a personalized follow-up procedure for HF on patient’s outcomes and care associated cost, based on a clinical model of risk stratification and personalized management according to that risk. A total of 192 patients were enrolled and studied before the intervention and again after the intervention. The primary objective was the rate of readmissions, due to a HF. Secondary outcome compared the rate of ED visits and quality of life improvement assessed by the number of patients who had reduced NYHA score. A cost-analysis was also performed on these data. Results Admission rates significantly decreased by 19.8% after the intervention (from 30.2 to 10.4), the total hospital admissions were reduced by 32 (from 78 to 46) and the total length of stay was reduced by 7 days (from 15 to 9 days). The rate of ED visits was reduced by 44% (from 64 to 20). Thirty-one percent of patients had an improved functional class score after the intervention, whereas only 7.8% got worse. The overall cost saving associated with the intervention was € 72,769 per patient (from € 201,189 to € 128,420) and €139,717.65 for the whole group over 1 year. Conclusions A personalized follow-up of HF patients led to important outcome benefits and resulted in cost savings, mainly due to the reduction of patient hospitalization readmissions and a significant reduction of care-associated costs, suggesting that greater attention should be given to this high-risk cohort to minimize the risk of hospitalization readmissions.

IntroductionThe COVID-19 pandemic has seen the introduction of important public health measures to minimise the spread of the virus. We aim to identify the impact government restrictions and hospital-based infection control procedures on ST elevation myocardial infarction (STEMI) care during the COVID-19 pandemic.MethodsPatients meeting ST elevation criteria and undergoing primary percutaneous coronary intervention from 27 March 2020, the day initial national lockdown measures were announced in Ireland, were included in the study. Patients presenting after the lockdown period, from 18 May to 31 June 2020, were also examined. Time from symptom onset to first medical contact (FMC), transfer time and time of wire cross was noted. Additionally, patient characteristics, left ventricular ejection fraction, mortality and biochemical parameters were documented. Outcomes and characteristics were compared against a control group of patients meeting ST elevation criteria during the month of January.ResultsA total of 42 patients presented with STEMI during the lockdown period. A significant increase in total ischaemic time (TIT) was noted versus controls (8.81 hours (±16.4) vs 2.99 hours (±1.39), p=0.03), with increases driven largely by delays in seeking FMC (7.13 hours (±16.4) vs 1.98 hours (±1.46), p=0.049). TIT remained significantly elevated during the postlockdown period (6.1 hours (±5.3), p=0.05), however, an improvement in patient delays was seen versus the control group (3.99 hours (±4.5), p=0.06). There was no difference seen in transfer times and door to wire cross time during lockdown, however, a significant increase in transfer times was seen postlockdown versus controls (1.81 hours (±1.0) vs 1.1 hours (±0.87), p=0.004).ConclusionA significant increase in TIT was seen during the lockdown period driven mainly by patient factors highlighting the significance of public health messages on public perception. Additionally, a significant delay in transfer times to our centre was seen postlockdown.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction A number of randomized controlled trials have examined the effect of exercise training on left ventricle (LV) remodeling in individuals with cardiovascular disease. However, the results of these trials have been inconclusive.  Purpose Evaluation of the impact of a cardiac rehabilitation program (CRP) on left ventricle remodelling evaluated by echocardiogram.  Methods Observational single centre study including consecutive patients, undergoing structured CRP since June 2016 until February 2020. Phase II CRP included 3 months of exercise training, aerobic and strength exercise, individually prescribed, 3 times a week, 60 minutes sessions. All patients were submitted to a clinical evaluation, echocardiogram, and cardiopulmonary exercise test before and after the CRP. Results 205 patients (62.6 ± 11 years, 83.4% men, 82.3% ischemic disease) were included in a phase II CRP. Most patients had ischemic disease (82.3%) and 23.5% of patients had left ventricular ejection fraction (LVEF) &lt;40%. Of the cardiovascular risk factors, hypertension was the most prevalent (76%), followed by dyslipidaemia (67.4%), active smoking (45.9%) and diabetes (26.9%).  After the CRP, there was a significant improvement of LVEF (from 48.3 ± 13 to 52 ± 11.6 %, p = 0.001) and a significant reduction of LV volumes (LV end-diastolic volume, LVEDV , decreased from 140 ± 81 to 121 ± 57, p = 0.002; LV end-systolic volume , LVESV , reduced from 80 ± 75 to 64 ± 48, p = 0.004). Considering only the patients with LVEF &lt; 40% (n = 38), the improvement was even greater: LVEF increased from 30 ± 8 to 39 ± 13 (p = 0.002); LVEDV reduced from 206 ± 107 to 159 ± 81 (p = 0.001) and LVESV reduced from 142 ± 99 to 101 ± 66 (p = 0.002). 63.6%(n = 14) of these patients improved at least 10% of LVEF and only 1 of them had a cardiac resynchronization therapy device.  Conclusions A phase II CR program was associated with significant improvements in left ventricular reverse remodelling irrespective of baseline EF classification. Those with reduced baseline EF derived an even greater improvement, highlighting the great importance of CR in this subgroup of patients.

Abstract Background The CBR3 V244M single nucleotide polymorphism has been linked to the risk of anthracycline-related cardiomyopathy in survivors of childhood cancer. There have been limited prospective studies examining the impact of CBR3 V244M on the risk for anthracycline-related cardiotoxicity in adult cohorts. Objectives This study evaluated the presence of associations between CBR3 V244M genotype status and changes in echocardiographic parameters in breast cancer patients undergoing doxorubicin treatment. Methods We recruited 155 patients with breast cancer receiving treatment with doxorubicin (DOX) at Roswell Park Comprehensive Care Center (Buffalo, NY) to a prospective single arm observational pharmacogenetic study. Patients were genotyped for the CBR3 V244M variant. 92 patients received an echocardiogram at baseline (t0 month) and at 6 months (t6 months) of follow up after DOX treatment. Apical two-chamber and four-chamber echocardiographic images were used to calculate volumes and left ventricular ejection fraction (LVEF) using Simpson’s biplane rule by investigators blinded to all patient data. Volumetric indices were evaluated by normalizing the cardiac volumes to the body surface area (BSA). Results Breast cancer patients with CBR3 GG and AG genotypes both experienced a statistically significant reduction in LVEF at 6 months following initiation of DOX treatment for breast cancer compared with their pre-DOX baseline study. Patients homozygous for the CBR3 V244M G allele (CBR3 V244) exhibited a further statistically significant decrease in LVEF at 6 months following DOX therapy in comparison with patients with heterozygous AG genotype. We found no differences in age, pre-existing cardiac diseases associated with myocardial injury, cumulative DOX dose, or concurrent use of cardioprotective medication between CBR3 genotype groups. Conclusions CBR3 V244M genotype status is associated with changes in echocardiographic parameters suggestive of early anthracycline-related cardiomyopathy in subjects undergoing chemotherapy for breast cancer.

AimsThere is an increasing awareness of gender-related differences in patients with severe aortic stenosis and their outcomes after surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI).MethodsData from the IMPULSE registry were analysed. Patients with severe aortic stenosis (AS) were enrolled between March 2015 and April 2017 and stratified by gender. A subgroup analysis was performed to assess the impact of age.ResultsOverall, 2171 patients were enrolled, and 48.0% were female. Women were characterised by a higher rate of renal impairment (31.7 vs 23.3%; p<0.001), were at higher surgical risk (EuroSCORE II: 4.5 vs 3.6%; p=0.001) and more often in a critical preoperative state (7.0vs 4.2%; p=0.003). Men had an increased rate of previous cardiac surgery (9.4 vs 4.7%; p<0.001) and a reduced left ventricular ejection fraction (4.9 vs 1.3%; p<0.001). Concomitant mitral and tricuspid valve disease was substantially more common among women. Symptoms were highly prevalent in both women and men (83.6 vs 77.3%; p<0.001). AVR was planned in 1379 cases. Women were more frequently scheduled to undergo TAVI (49.3 vs 41.0%; p<0.001) and less frequently for SAVR (20.3 vs 27.5%; p<0.001).ConclusionsThe present data show that female patients with severe AS have a distinct patient profile and are managed in a different way to males. Gender-based differences in the management of patients with severe AS need to be taken into account more systematically to improve outcomes, especially for women.
