Abstract
Abstract
Background
Hospitalization for heart failure and death are among the most common adverse clinical outcomes in patients with atrial fibrillation (AF). The underlying mechanisms are poorly understood.
Purpose
We hypothesised that inflammation, quantified by plasma levels of C-reactive protein (CRP) and interleukin 6 (IL-6), is independently associated with hospitalization for heart failure and death in a large, contemporary cohort of AF patients.
Methods
Patients with established AF and 65 years of age or older were enrolled in two large, prospective, multicentre cohort studies in Switzerland. Plasma levels of high-sensitivity (hs) CRP and IL-6 were measured from frozen EDTA plasma samples obtained at baseline. Using these two biomarkers, we calculated an inflammation score ranging from 0 to 4 (1 point for each biomarker between the 50th and 75th percentile, 2 points for each biomarker above the 75th percentile). We constructed multivariable Cox proportional hazards models to quantify the associations of hs-CRP, IL-6 and the inflammation score with time to first hospitalization for heart failure and time to all-cause mortality, respectively.
Results
A total of 3,784 patients with AF (median age 72 years, 28% women, 24% with a prior history of heart failure and 84% anticoagulation use at baseline) were followed for a median (interquartile range [IQR]) of 4.0 (2.9–5.1) years. The median (IQR) plasma levels of hs-CRP and IL-6 at baseline were 1.64 (0.81–3.69) mg/L and 3.42 (2.14–5.60) pg/mL, respectively. The incidence rates of hospitalization for heart failure and death were 3.04 and 2.80 per 100 person-years, respectively. After multivariable adjustment, both biomarkers were significantly associated with the risk of hospitalization for heart failure (per increase in 1 standard deviation [SD], adjusted hazard ratio [aHR] 1.22, 95% confidence interval [CI] 1.11–1.34 for log-transformed hs-CRP, and aHR 1.48, 95% CI 1.35–1.62 for log-transformed IL-6) and death (per increase in 1 SD, aHR 1.40, 95% CI 1.27–1.54 for log-transformed hs-CRP, and aHR 1.67, 95% CI 1.53–1.81 for log-transformed IL-6). Incidence rates of hospitalization for heart failure increased from 1.34 to 7.31 per 100 person-years across categories of the inflammation score (Figure 1). A strong relationship persisted after multivariable adjustment. Similar findings were observed for all-cause mortality.
Conclusions
Inflammation is a strong predictor of hospitalization for heart failure and death in patients with AF. Targeting inflammation may be a promising treatment strategy to improve outcomes in these patients at high risk for adverse outcomes.

Abstract
Abstract
Background
Observational studies showed promising results after treatment of coronary instent-restenosis (ISR) using the everolimus-eluting bioresorbable vascular scaffold (BVS) Absorb®.
Purpose
We compared long-term outcomes after treatment of ISR with BVS versus the paclitaxel-eluting drug coated balloon (PE-DCB) SeQuent® Please, which is commonly used for treatment of ISR.
Methods
This was randomized-controlled trial of Absorb® BVS versus SeQuent® Please PE-DCB in an all-comers population with clinically relevant ISR. The patients were randomized in a 1:1 fashion. The angiographic primary endpoint was late lumen loss (LLL) at 9 months. Clinical follow-ups (FU) up to 48 months were conducted.
Results
Totally, 53 patients and lesions were enrolled. The mean age was 66.7±9.8 years, 23 (43.4%) had an acute coronary syndrome (ACS) and 16 (30.2%) were diabetic. PCI was successful in all patients. After 9 months, the mean LLL did not significantly differ between patients treated with BVS versus PE-DCB (median 0.41 (interquartile range (IQR) 0.15; 1.23)mm versus 0.27 (IQR 0.13; 0.66)mm, p=0.86). Moreover, mean lumen area on optical coherence tomography (OCT) did not significantly differ (median 5.47 (IQR 4.44; 7.69)mm2 versus 6.70 (IQR 5.00; 7.82)mm2, p=0.24). Rates of significant ISR (angiographic stenosis >70%) were similar with BVS versus PE-DCB (7 (30.4%) versus 6 (27.3%), p=0.81). The target vessel revascularization rates were 9 (33.3%) versus 9 (34.6%) using the BVS versus PE-DCB (p=0.72), also highlighted in the Figure below). No stent/ scaffold thrombosis occurred during FU. The study was prematurely stopped due to withdrawal of the Absorb® BVS in September 2017.
Conclusions
In this randomized pilot study, we found no significant difference in angiographic, OCT and clinical endpoints after treatment of ISR lesions using the Absorb BVS versus SeQuent® Please PE-DCB during long-term follow-up (≥48months). However, rates of target vessel revascularization were very high in both groups (>30%).

Abstract
Abstract
Background
Patients with atrial fibrillation (AF) have a high risk of hospital admissions, but there is no validated prediction tool to identify those at highest risk.
Purpose
To develop and externally validate a risk score for all-cause hospital admissions in patients with AF.
Methods
We used a prospective cohort of 2387 patients with established AF as derivation cohort. Independent risk factors were selected from a broad range of variables using the least absolute shrinkage and selection operator (LASSO) method fit to a Cox regression model. The developed risk score was externally validated in a separate prospective, multicenter cohort of 1300 AF patients.
Results
In the derivation cohort, 891 patients (37.3%) were admitted to the hospital over a median follow-up 2.0 years. In the validation cohort, hospital admissions occurred in 719 patients (55.3%) during a median follow-up 1.9 years. The most important predictors for admission were age (75–79 years: adjusted hazard ratio [aHR], 1.33; 95% confidence interval [95% CI], 1.00–1.77; 80–84 years: aHR, 1.51; 95% CI, 1.12–2.03; ≥85 years: aHR, 1.88; 95% CI, 1.35–2.61), prior pulmonary vein isolation (aHR, 0.74; 95% CI, 0.60–0.90), hypertension (aHR, 1.16; 95% CI, 0.99–1.36), diabetes (aHR, 1.38; 95% CI, 1.17–1.62), coronary heart disease (aHR, 1.18; 95% CI, 1.02–1.37), prior stroke/TIA (aHR, 1.28; 95% CI, 1.10–1.50), heart failure (aHR, 1.21; 95% CI, 1.04–1.41), peripheral artery disease (aHR, 1.31; 95% CI, 1.06–1.63), cancer (aHR, 1.33; 95% CI, 1.13–1.57), renal failure (aHR, 1.18, 95% CI, 1.01–1.38), and previous falls (aHR, 1.44; 95% CI, 1.16–1.78). A risk score with these variables was well calibrated, and achieved a C-index of 0.64 in the derivation and 0.59 in the validation cohort.
Conclusions
Multiple risk factors were associated with hospital admissions in AF patients. This prediction tool selects high-risk patients who may benefit from preventive interventions.

Abstract
Abstract
Introduction
Limited information about the management and outcomes of patients with acute coronary syndromes (ACS) and moderate to severe renal failure (RF) is available owing to underrepresentation of this population in most studies.
Methods
We evaluated the use of guideline-recommended therapies and in-hospital outcomes of totally 49'191 ACS patients with normal-mild renal failure (RF) (defined as eGFR >45ml/min/m2) versus moderate-severe RF (eGFR <45ml/min/m2) enrolled in the prospective Acute Myocardial Infarction in Switzerland (AMIS) cohort between 2002 and 2019 according to 2-year periods.
Results
Overall, 3'478 (7.1%) patients had moderate-severe RF. They were older (65.2+12.9 versus 77.2+10.6 years) and had significantly more comorbidities (including heart failure, cerebrovascular and peripheral vascular disease). Moderate-severe RF patients received less frequently guideline-recommended drugs, including P2Y12 inhibitors, ACEI/ARBs and statins (p<0.0001). Between the first and last 2-year periods, the number of patients with moderate-severe RF and number of performed percutaneous coronary interventions (PCI) increased in this cohort (p-for-trend=0.001). At the same time, in-hospital mortality significantly decreased among ACS patients with and without RF (17.5% to 10.5% and 6.0% to 3.9%, respectively, p-for-trend=0.001 for both, see Figure). Similar trends were observed for other complications, namely cardiogenic shock and reinfarction. However, major bleedings increased significantly over time in patients with and without RF (p-for-trend=0.038 and <0.001, respectively).
Conclusions
Outcomes of ACS patients with moderate to severe RF improved over the last two decades. Even though the rate of PCI increased in ACS patients with moderate-severe RF, they were less likely to receive guideline-recommended therapies and still suffer a high in-hospitality mortality (>10%). With respect to the increasing burden of ACS patients with RF, our study implicates that more efforts should be undertaken to further improve outcomes of those patients.

Abstract
Abstract
Background
Guidelines recommend evaluating the risk/benefit ratio of novel therapies individually in women and men, as the pathophysiology and the response to treatment may differ between women and men. Among patients with acute heart failure (AHF), a strategy of intensive vasodilation, compared with usual care, overall did provide comparable outcomes.
Purpose
To evaluate the effect of a strategy that emphasized early intensive and sustained vasodilation in women with AHF.
Methods
In a randomized, open-label blinded-end-point trial patients hospitalized for AHF were enrolled in 10 hospitals in Switzerland, Bulgaria, Germany, Brazil, and Spain. Inclusion criteria were AHF expressed by acute dyspnea and increased plasma concentrations of natriuretic peptides, systolic blood pressure ≥100mmHg, and a plan for treatment in a general ward. Patients were randomized 1:1 to a strategy of early intensive and sustained vasodilation throughout the hospitalization or usual care. The primary end point was a composite of all-cause mortality or rehospitalization for AHF at 180 days.
Results
Among 788 patients randomized, 781 completed the trial and were eligible for the primary end point analysis. Of these 288 (36.9%) were women. The primary end point, a composite of all-cause mortality or rehospitalization for AHF at 180 days, occurred in 53 female patients (37.9%) in the intervention group (including 28 deaths [20.0%]) and in 34 female patients (23.0%) in the usual care group (including 22 deaths [14.9%]) (absolute difference for the primary end point, 14.9%; adjusted hazard ratio, 1.67 [95% CI: 1.08–2.59]; P=0.02). Clinically significant adverse events with early intensive and sustained vasodilation vs usual care included hypotension (8% vs 2%).
Conclusion
Among women with AHF, a strategy of early intensive and sustained vasodilation, compared with usual care, had a detrimental effect on a composite outcome of all-cause mortality and AHF rehospitalization at 180 days.

Abstract
AIMS We aimed to evaluate the frequency, clinical features, and prognostic implications of cardiac arrest (CA) in takotsubo syndrome (TTS). METHODS AND RESULTS We reviewed the records of patients with CA and known heart rhythm from the International Takotsubo Registry. The main outcomes were 60-day and 5-year mortality. In addition, predictors of mortality and predictors of CA during the acute TTS phase were assessed. Of 2098 patients, 103 patients with CA and known heart rhythm during CA were included. Compared with patients without CA, CA patients were more likely to be younger, male, and have apical TTS, atrial fibrillation (AF), neurologic comorbidities, physical triggers, and longer corrected QT-interval and lower left ventricular ejection fraction on admission. In all, 57.1% of patients with CA at admission had ventricular fibrillation/tachycardia, while 73.7% of patients with CA in the acute phase had asystole/pulseless electrical activity. Patients with CA showed higher 60-day (40.3% vs. 4.0%, P < 0.001) and 5-year mortality (68.9% vs. 16.7%, P < 0.001) than patients without CA. T-wave inversion and intracranial haemorrhage were independently associated with higher 60-day mortality after CA, whereas female gender was associated with lower 60-day mortality. In the acute phase, CA occurred less frequently in females and more frequently in patients with AF, ST-segment elevation, and higher C-reactive protein on admission. CONCLUSIONS Cardiac arrest is relatively frequent in TTS and is associated with higher short- and long-term mortality. Clinical and electrocardiographic parameters independently predicted mortality after CA.

Abstract
INTRODUCTION Sudden cardiac death caused by malignant arrhythmia can be prevented by the use of defibrillators. Although the wearable cardioverter defibrillator (WCD) can prevent such an event, its role in clinical practice is ill defined. We investigated the use of the WCD in Switzerland with emphasis on prescription rate, therapy adherence and treatment rate. MATERIALS AND METHODS The Swiss WCD Registry is a retrospective observational registry including patients using a WCD. Patients were included from the first WCD use in Switzerland until February 2018. Baseline characteristics and data on WCD usage were examined for the total study population, and separately for each hospital. RESULTS From 1 December 2011 to 18 February 2018, a total of 456 patients (67.1% of all WCDs prescribed in Switzerland and 81.1% of all prescribed in the participating hospitals) were included in the registry. Up to 2017 there was a yearly increase in the number of prescribed WCDs to a maximum of 271 prescriptions per year. The mean age of patients was 57 years (± 14), 81 (17.8%) were female and mean left ventricular ejection fraction (EF) was 32% (± 13). The most common indications for WCD use were new-onset ischaemic cardiomyopathy (ICM) with EF ≤35% (206 patients, 45.2%), new-onset nonischaemic cardiomyopathy (NICM) with EF ≤35% (115 patients, 25.2%), unknown arrhythmic risk (83 patients, 18.2%), bridging to implantable cardioverter-defibrillator implantation or heart transplant (37 patients, 8.1%) and congenital/inherited heart disease (15 patients, 3.3%). Median wear duration was 58 days (interquartile range [IQR] 31–94) with a median average daily wear time of 22.6 hours (IQR 20–23.2). Seventeen appropriate therapies from the WCD were delivered in the whole population (treatment rate: 3.7%) to a total of 12 patients (2.6% of all patients). The most common underlying heart disease in patients with a treatment was ICM (13/17, 76.5%). There were no inappropriate treatments. CONCLUSION The use of WCDs has increased in Switzerland over the years for a variety of indications. There is high therapy adherence to the WCD, and a treatment rate comparable to previously published registry data.  .

Abstract
Background This study evaluated the use of comprehensive geriatric assessment (CGA) in older patients undergoing pacemaker implantation. Methods In this prospective cohort, CGA was performed in 197 patients ≥75 years at pacemaker implantation and yearly thereafter. CGA embraced the following domains: cognition, mobility, nutrition, activities of daily living (ADLs), and falls (with or without loss of consciousness). Based on comorbidities, the Charlson comorbidity index (CCI) was calculated. For predictive analysis, logistic regression was used. Results During a mean follow-up duration of 2.4 years, the incidence rates of syncope decreased from 0.46 to 0.04 events per year (p < 0.001), and that of falls without loss of consciousness from 0.27 to 0.15 (p < 0.001) before vs. after implantation. Sixty-three patients (32.0%) died. Impaired mobility (OR 2.60, 95%CI 1.22–5.54, p = 0.013), malnutrition (OR 3.26, 95%CI 1.52–7.01, p = 0.002), and a higher CCI (OR per point increase 1.25, 95%CI 1.04–1.50, p = 0.019) at baseline were significant predictors of mortality. Among 169 patients who survived for more than 1 year and thus underwent follow-up CGA, CGA domains did not deteriorate during follow-up, except for ADLs. This decline in ADLs during follow-up was the strongest predictor of later nursing home admission (OR 9.29, 95%CI 1.82–47.49, p = 0.007). Higher baseline age (OR per year increase 1.10, 95%CI 1.02–1.20, p = 0.018) and a higher baseline CCI (OR per point increase 1.32, 95%CI 1.05–1.65, p = 0.017) were associated with a decline in ADLs during follow-up. Conclusions CGA is useful to detect functional deficits, which are associated with mortality or nursing home admission after pacemaker implantation. The present study seems to support the use of CGA in older patients undergoing pacemaker implantation as functional deficits and falls are amenable to geriatric interventions.

Abstract
Background Impaired heart rate variability (HRV) is associated with increased mortality in sinus rhythm. However, HRV has not been systematically assessed in patients with atrial fibrillation (AF). We hypothesized that parameters of HRV may be predictive of cardiovascular death in patients with AF. Methods and Results From the multicenter prospective Swiss‐AF (Swiss Atrial Fibrillation) Cohort Study, we enrolled 1922 patients who were in sinus rhythm or AF. Resting ECG recordings of 5‐minute duration were obtained at baseline. Standard parameters of HRV (HRV triangular index, SD of the normal‐to‐normal intervals, square root of the mean squared differences of successive normal‐to‐normal intervals and mean heart rate) were calculated. During follow‐up, an end point committee adjudicated each cause of death. During a mean follow‐up time of 2.6±1.0 years, 143 (7.4%) patients died; 92 deaths were attributable to cardiovascular reasons. In a Cox regression model including multiple covariates (age, sex, body mass index, smoking status, history of diabetes mellitus, history of hypertension, history of stroke/transient ischemic attack, history of myocardial infarction, antiarrhythmic drugs including β blockers, oral anticoagulation), a decreased HRV index ≤ median (14.29), but not other HRV parameters, was associated with an increase in the risk of cardiovascular death (hazard ratio, 1.7; 95% CI, 1.1–2.6; P=0.01) and all‐cause death (hazard ratio, 1.42; 95% CI, 1.02–1.98; P=0.04). Conclusions The HRV index measured in a single 5‐minute ECG recording in a cohort of patients with AF is an independent predictor of cardiovascular mortality. HRV analysis in patients with AF might be a valuable tool for further risk stratification to guide patient management.

Abstract
Aims Atrial fibrillation (AF) and atrial flutter (AFL) are two of the most common atrial arrhythmias and often coexist. Many patients with AF or AFL are symptomatic, which impacts their quality of life (QoL). The purpose of this study was to determine whether coexistent AFL represents an added burden for AF patients. Methods We combined baseline data from two large prospective, observational, multicenter cohort studies (BEAT-AF and Swiss-AF). All 3931 patients included in this analysis had documented AF. We obtained information on comorbidities, medication, and lifestyle factors. All participants had a clinical examination and a resting ECG. Symptom burden and QoL at the baseline examination were compared between patients with and without coexistent AFL using multivariable adjusted regression models. Results Overall, 809 (20.6%) patients had a history of AFL. Patients with coexistent AFL more often had history of heart failure (28% vs 23%, p = 0.01), coronary artery disease (30% vs 26%, p = 0.007), failed therapy with antiarrhythmic drugs (44% vs 29%, p < 0.001), and more often underwent AF-related interventions (36% vs 17%, p < 0.001). They were more often symptomatic (70% vs 66%, p = 0.04) and effort intolerant (OR: 1.14; 95% CI: 1.01-1.28; p = 0.04). Documented AFL on the baseline ECG was associated with more symptoms (OR: 2.30; 95% CI: 1.26-4.20; p = 0.007). Conclusion Our data indicates that patients with coexistent AF and AFL are more often symptomatic and report poorer quality of life compared to patients suffering from AF only.

Abstract
Abstract
Background/Introduction
The use of a standardized ‘CLOSE’ ablation workflow for pulmonary vein isolation (PVI), with defined inter-tag distance (ITD) with targeted ablation index (AI) values, has been shown in single centre reports to result in good outcomes. The effect of this approach on patients’ quality of life (QoL) has not been studied.
Purpose
To evaluate the effects of paroxysmal atrial fibrillation (PAF) ablation by the CLOSE workflow on QoL and symptomatic AF reduction in the multicenter VISTAX study.
Methods
329 patients with PAF (61.5% male, 61.3 ± 10.1 year) were treated at 17 European centres by point-by-point radiofrequency ablation using the CLOSE protocol to achieve PVI. An ITD ≤6mm and AI values of ≥400 on the posterior wall and ≥550 on the anterior wall were targeted. The AI value on the posterior wall was lowered as per investigator discretion in case of safety concerns. Patients were monitored for atrial arrhythmia recurrences via weekly and symptom-activated transtelephonic monitoring (TTM), for 12 months post procedure. Patients completed an Atrial Fibrillation Effect on Quality-of-life (AFEQT) questionnaire at their baseline and 12-month follow up visits.
Results
Majority (83.3% [274/329]) of patients experienced freedom from symptomatic atrial recurrence through 12 months. Of the 70 documented recurrences, 34 (49%) were documented by trans-telephonic monitoring only. All domains captured on the AFEQT questionnaire showed improvement with the overall score improving by 25.7, which exceeded the threshold of clinically meaningful improvement (±5) (Table). Patient reported most improvements in PAF control and symptoms relieved. The overall AFEQT score improvement was seen both in patients with or without documented atrial arrhythmia recurrence, with improvement by 21.5 and 26.8, respectively.
Conclusion
PAF ablation using a standardized CLOSE workflow resulted in consistent improvements in QoL. The improved QoL was observed regardless of atrial arrhythmia recurrence likely reflecting the low residual arrhythmia burden in patients with documented recurrence identified only on TTM.

Abstract
Abstract
Background/Introduction
The ‘CLOSE’ protocol, incorporating standardized ablation index (AI) targets in conjunction with defined inter-tag distance (ITD) has been shown to improve the acute and long-term success of pulmonary vein isolation (PVI) when treating paroxysmal atrial fibrillation (PAF). The reproducibility and learning curve for this protocol has not been studied.
Purpose
To assess the acute and long-term efficacy of CLOSE PVI across multiple operators (n = 37) in the 17-centre European study ‘VISTAX’.
Methods
329 patients with PAF (61.8% male, 61.3 ± 10.1 years) underwent PVI according to the CLOSE protocol, with target AI values for each lesion of ≥400 on the posterior wall and ≥550 on the anterior wall, and target ITD of ≤6mm. Each 3-dimensional electroanatomic map was evaluated at a core lab where adherence to each of these criteria was assessed. 281/329 patients (85.1%) fulfilled all standardized workflow requirements and were adjudicated as having their PVI per-protocol (PP). First pass PVI and acute effectiveness (adenosine-proof first pass PVI at 30-minute challenge) were recorded. Clinical effectiveness was assessed as freedom from atrial arrhythmia recurrence through 12 months recorded via transtelephonic monitoring (weekly and symptomatically), in addition to holter and electrocardiogram monitoring during 3,6,12 month follow up visits. Learning curve analysis was evaluated on all investigators.
Results
First pass PVI rates were similar in the overall (86%) and PP cohorts (85%), as was acute effectiveness (82% in both cohorts). Freedom from atrial arrhythmia at 12 months too was identical for both cohorts (79%). Total procedure time and total ablation time decreased by an average 8 minutes and 10 minutes respectively after the first procedure and then showed further steady decreases over the number of ablations performed by the investigator (Figure). The procedural efficiencies and clinical success were reproducible across different centers. No significant deviations were found from individual sites.
Conclusion
The standardized CLOSE workflow is reproducible across centres, and is ‘forgiving’ without impacting on high efficacy of almost 80%. The learning curve is short, suggesting that the excellent clinical results can be replicated widely and easily.

Abstract
Background Previous reports have described a leveling off of mortality from premature coronary artery disease (CAD). In recent years, the prevalence of cardiovascular risk factors has increased in rural communities and young adults. Methods and Results We extracted CAD mortality rates from the Centers for Disease Control and Prevention Wide‐Ranging Online Data for Epidemiologic Research (CDC WONDER) database from 1999 to 2017, focusing on mortality from premature CAD (defined as <65 years of age in women) and urban–rural differences. Variations in mortality rates over time, assessed with Joinpoint regression modeling, are expressed as estimated annual percentage change (95% CI) and stratified by urbanization, sex, age, and race. Age‐adjusted mortality rates decreased for women and men. Stratification by urbanization revealed that premature CAD mortality is stagnating among women in rural areas. However, this stagnation conceals a statistically significant increase in CAD mortality rates since 2009 in women aged 55 to 64 years (estimated annual percentage change: +1.4%; 95% CI, +0.3% to +2.5%) and since 1999 in women aged 45 to 54 years (estimated annual percentage change: +0.6%; 95% CI, +0.2% to 1.0%). Since 1999, mortality has been stagnating in the youngest group (aged 35–44 years; estimated annual percentage change: +0.2%; 95% CI, −0.4% to +0.8%). Stratification by race indicated an increase in mortality rates among white rural women. Premature CAD mortality remains consistently higher in the rural versus urban United States, regardless of sex, race, and age group. Conclusions Premature CAD mortality rates have declined over time. However, stratification by sex and urbanization reveals disparities that would otherwise remain concealed: CAD mortality rates have increased among women from rural areas since at least 2009.

Abstract
OBJECTIVE We aimed to investigate changes in atrial fibrillation (AF)-related symptoms and quality of life (QoL) over time, and their impact on prognosis. METHODS We prospectively followed 3836 patients with known AF for a mean of 3.7 years. Information on AF-related symptoms and QoL was obtained yearly. The primary end point was a composite of stroke or systemic embolism. Main secondary end points included stroke subtypes, all-cause mortality, cardiovascular death, hospitalisation for congestive heart failure (CHF), myocardial infarction and major bleeding. We assessed associations using multivariable, time-updated Cox proportional hazards models. RESULTS Mean age was 72 years, 72% were male. Patients with AF-related symptoms (66%) were younger (70 vs 74 years, p<0.0001), more often had paroxysmal AF (56% vs 37%, p<0.0001) and had lower QoL (71 vs 72 points, p=0.009). The incidence of the primary end point was 1.05 and 1.02 per 100 person-years in patients with and without symptoms, respectively. The multivariable adjusted HR (aHR) (95% CIs) for the primary end point was 1.11 (0.77 to 1.59; p=0.56) for AF-related symptoms. AF-related symptoms were not associated with any of the secondary end points. QoL was not significantly related to the primary end point (aHR per 5-point increase 0.98 (0.94 to 1.03; p=0.37)), but was significantly related to CHF hospitalisations (0.92 (0.90 to 0.94; p<0.0001)), cardiovascular death (0.90 (0.86 to 0.95; p<0.0001)) and all-cause mortality (0.88 (0.86 to 0.90; p<0.0001)). CONCLUSIONS AF-related symptoms were not associated with adverse outcomes and should therefore not be the basis for prognostic treatment decisions. QoL was strongly associated with CHF, cardiovascular death and all-cause mortality.

Abstract
Abstract
Aims
To develop and externally validate a risk score for all-cause hospital admissions in patients with atrial fibrillation.
Methods and results
We used a prospective cohort of 2387 patients with established atrial fibrillation as derivation cohort. Independent risk factors were selected from a broad range of variables using the least absolute shrinkage and selection operator method fit to a Cox model. The risk score was validated in a separate prospective cohort of 1300 atrial fibrillation patients. The incidence of all-cause hospital admission was 19.1 per 100 person-years in the derivation cohort and it was 26.1 per 100 person-years in the validation cohort. The most important predictors for admission were age (75–79 years: adjusted hazard ratio (aHR), 1.34; 95% confidence interval (CI), 1.01–1.78; 80–84 years: aHR, 1.50; 95% CI, 1.11–2.03; ≥85 years: aHR, 1.88; 95% CI, 1.36–2.62), prior pulmonary vein isolation (aHR, 0.72; 95% CI, 0.58–0.88), hypertension (aHR, 1.16; 95% CI, 0.99–1.36), diabetes (aHR, 1.38; 95% CI, 1.17–1.62), coronary heart disease (aHR, 1.17; 95% CI, 1.02–1.36), prior stroke/transient ischaemic attack (aHR, 1.26; 95% CI, 1.18–1.47), heart failure (aHR, 1.19; 95% CI, 1.03–1.39), peripheral artery disease (aHR, 1.35; 95% CI, 1.08–1.67), cancer (aHR, 1.33; 95% CI, 1.12–1.57), renal failure (aHR, 1.17; 95% CI, 0.99–1.37) and previous falls (aHR, 1.40; 95% CI, 1.13–1.74). A risk score with these variables was well calibrated, and achieved a C-index of 0.64 in the derivation and 0.59 in the validation cohort.
Conclusions
Multiple risk factors were associated with hospital admissions in atrial fibrillation patients. This prediction tool selects high-risk patients who may benefit from preventive interventions.

Abstract
The ACURATE neo transcatheter heart valve has been associated with very low rates of new conduction disorders (CDs). We assessed the clinical relevance of new CDs in patients undergoing transcatheter aortic valve replacement (TAVR) with this valve. Data of consecutive patients without a pre-existing left bundle branch block (LBBB) or a permanent pacemaker (PPM) undergoing TAVR with the ACURATE neo were analyzed from the prospective SwissTAVI registry. Patients with new CDs were compared with patients with an unchanged electrocardiogram (ECG). ACURATE neo was implanted in 203 patients (mean age 82 ± 6 years, 63% women), CDs occurred in 28 patients (22 [11%] developed a LBBB, 6 [3%] required a PPM). New CDs resulted in a longer median duration of hospitalization (7 vs 5 days, interquartile range 4 to 13 vs 3 to 8 days, p = 0.04). At 1-year follow-up, left ventricular ejection fraction was significantly lower in patients with new CDs comparedwith patients with an unchanged ECG (54% ± 13% vs 61% ± 9%, p <0.01). Kaplan-Meier estimates of survival at 1-year were 89% in patients with new CDs and 95% in patients with an unchanged ECG (hazard ratio 2.0, 95% confidence interval 0.7 to 6.2, p = 0.22). After TAVR with the self-expanding ACURATE neo valve, the rate of new CDs, including complete LBBB was low and very few patients required a new PPM. However, new CDs prolonged initial hospitalization and increased the risk for left ventricular-dysfunction at 1-year follow-up. Patients without new CDs had excellent outcomes with a very high survival rate at 1-year follow-up.

Abstract
OBJECTIVES This study aimed to investigate the safety and efficacy of ACURATE neo transcatheter aortic valve replacement (TAVR) facilitated by predilatation with the nonocclusive TrueFlow balloon catheter. BACKGROUND Now that TAVR is moving forward, physicians have attempted to simplify and streamline the procedure and the so-called minimalist approach has become more popular. METHODS We enrolled 142 patients (mean age: 82 ± 5 years, 61% female) in a prospective registry. Patients at low risk for intraprocedural third-degree atrioventricular block (AVB) underwent TAVR with the TrueFlow balloon without rapid pacing and without insertion of a provisional pacemaker (n = 121). The remaining 21 patients were predilated with rapid pacing using a provisional pacemaker and a standard balloon. RESULTS Predilatation with the TrueFlow balloon was successful in all 121 patients. Postdilatation was less frequently required after predilatation with the TrueFlow (25% vs. 57%, p = .003). Moreover, median procedural duration with the TrueFlow was significantly shorter (42 [interquartile range, IQR: 34-53] vs. 55 [IQR: 46-61] min, p = .004). In-hospital outcomes were similar. At 30 days, there was no mortality, two (1%) patients had suffered a stroke and only four (3%) had required implantation of a new pacemaker. CONCLUSION Among patients with a low risk for intraprocedural third-degree AVB, the TrueFlow nonocclusive balloon catheter facilitates implantation of the ACURATE neo without the necessity of rapid pacing and a provisional pacemaker.

Abstract
Introduction Stent underexpansion is a predictor of in-stent-restenosis and stent thrombosis. Semi-compliant balloons (SCBs) are generally used for lesion preparation. It remains unknown whether routine predilatation using non-compliant balloons (NCBs) improves stent expansion in ordinary coronary lesions. Methods The PREdilatation by high-pressure NC balloon catheter for better vessel preparation and Optimal lesion preparation with non-compliant balloons for the implantation of bioresorbable vascular scaffolds studies randomised patients presenting with stable coronary artery disease or non-ST-elevation myocardial infarction requiring stent implantation to lesion preparation using NCBs versus SCBs. Stent expansion index (SEI-minimal luminal area/mean luminal area on optical coherence tomography) and periprocedural complications were compared. Results We enrolled 104 patients: 53 patients (54 lesions) vs 51 patients (56 lesions) to the NCB and SCB groups, respectively. Predilatation pressure was higher in the NCB group (24±7 atmospheres (atm) vs 14±3 atm, p<0.0001). Postdilatation using NCBs was performed in 41 (76%) lesions vs 46 (82%) lesions pretreated with NCBs versus SCBs (p=0.57). Similar pressures were used for postdilatation with NCB in both groups (23±8 atm vs 23±9 atm, p=0.65). SEI after stent implantation was 0.88±0.13 in the NCB vs 0.85±0.14 in the SCB group (p=0.18). After postdilatation, SEI increased to 0.94±0.13 in the NCB group vs 0.88±0.13 in the SCB group (p=0.02). No relevant complications occurred. Conclusions In simple coronary lesions, predilatation/postdilatation with NCBs at high pressures appears to result in better scaffold and stent expansion. Using SCBs only for predilatation might lead to inadequate stent expansion and postdilatation with NCBs might only partially correct this. Predilatation and postdilatation using NCBs at high pressure is safe. Trial registration number ClinicalTrials.gov no. NCT03518645.

Abstract
Description
We report about a 59-year old asymptomatic woman initially presented with lateral T-wave inversions in a routine ECG. Echocardiography suggested isolated left ventricular non-compaction (LVNC). An additional cardiac magnetic resonance imaging (cMRI) showed positive diagnostic criteria for LVNC. Six years later a diagnostic coronary angiogram revealed by a coincidence extensive shunting from the left coronary arteries to the left ventricle through Thebesian veins (sinusoids). Finally color Doppler flow confirmed that the irregular anatomy of the LV was not a result of incomplete LV compaction but due to the coronary anomaly.
Initial work up
A 59-year old asymptomatic woman presented with lateral T-wave inversions in a routine ECG. Echocardiography suggested isolated left ventricular non-compaction (LVNC) with deep recesses and a systolic non-compacted to compacted ratio in short axis of >2. To confirm the diagnosis cardiac magnetic resonance imaging (cMRI) was performed. Quality was not optimal due to premature contractions and insufficient breath-hold, but positive diagnostic criteria for LVNC (as described by Petersen, Left ventricular non-compaction: insights from cardiovascular magnetic resonance imaging. JACC, 2005 July 5;46(1):101-5) were reported (Figure 1A).
Diagnosis and Management
Six years later, the patient was referred to our institution for catheter ablation of a suspected paroxysmal supraventricular tachycardia causing palpitations. Since the patient also complained about recurrent chest pain, a coronary angiogram was performed in the same session and revealed a chronic total occlusion of the right coronary artery. However, also extensive shunting from the left coronary arteries to the left ventricle through Thebesian veins (sinusoids) was observed (Figure 1B, arrows).
Follow-up
In light of this new finding, echocardiography was repeated and color Doppler flow revealed diastolic filling of the recesses not from the LV cavity but from the coronary system, confirming that the irregular anatomy of the LV was not a result of incomplete LV compaction but due to the coronary anomaly (Figure 1C, apical short axis view, upper panel color Doppler in diastole, lower panel color M-mode). To exclude concurrent LVNC a cardiac CT was performed, confirming that the recesses, which initially led to the diagnosis of LVNC, exhibited diastolic flow from the coronary system (Figure 1D).
Conclusion
This case exemplifies that for the diagnosis of LVNC all echocardiographic criteria as defined by Oechslin and Jenni (Left ventricular non-compaction revisited: a distinct phenotype with genetic heterogeneity. EHJ, 2011 June;Volume 32, Issue 12, Pages 1446–1456) need to be fulfilled – including color Doppler assessment of flow in the recesses. Consequently, it illustrates that cMRI alone is not sufficient for the diagnosis of LVNC but both echocardiographic and cMRI criteria need to be applied.

Abstract
Objective:
Takotsubo syndrome (TTS) is characterized by acute left ventricular dysfunction, which can contribute to intraventricular thrombus and embolism. Still, prevalence and clinical impact of thrombus formation and embolic events on outcome of TTS patients remain unclear. This study aimed to investigate clinical features and outcomes of patients with and without intraventricular thrombus or embolism. Additionally, factors associated with thrombus formation or embolism, as well as predictors for mortality, were identified.
Approach and Results:
TTS patients enrolled in the International Takotsubo Registry at 28 centers in Australia, Europe, and the United States were dichotomized according to the occurrence/absence of intraventricular thrombus or embolism. Patients with intraventricular thrombus or embolism were defined as the ThrombEmb group. Of 1676 TTS patients, 56 (3.3%) patients developed intraventricular thrombus and/or embolism following TTS diagnosis (median time interval, 2.0 days [range, 0–38 days]). Patients in the ThrombEmb group had a different clinical profile including lower left ventricular ejection fraction, higher prevalence of the apical type, elevated levels of troponin and inflammatory markers, and higher prevalence of vascular disease. In a Firth bias-reduced penalized-likelihood logistic regression model apical type, left ventricular ejection fraction ≤30%, previous vascular disease, and a white blood cell count on admission >10×10
3
cells/μL emerged as independent predictors for thrombus formation or embolism.
Conclusions:
Intraventricular thrombus or embolism occur in 3.3% of patients in the acute phase of TTS. A simple risk score including clinical parameters associated with intraventricular thrombus formation or embolism identifies patients at increased risk.
