Abstract
BackgroundMicrovascular obstruction (MVO) and Late Gadolinium Enhancement (LGE) assessed in cardiac magnetic resonance (CMR) are associated with adverse outcome in patients with ST-elevation myocardial infarction (STEMI). Our aim was to analyze the diagnostic performance of segmental strain for the detection of MVO and LGE.MethodsPatients with anterior STEMI, who underwent additional CMR were enrolled in this sub-study of the CARE-AMI trial. Using CMR feature tracking (FT) segmental circumferential peak strain (SCS) was measured and the diagnostic performance of SCS to discriminate MVO and LGE was assessed in a derivation and validation cohort.ResultsForty-eight STEMI patients (62 ± 12 years old), 39 (81%) males, who underwent CMR (i.e., mean 3.0 ± 1.5 days) after primary percutaneous coronary intervention (PCI) were included. All patients presented with LGE and in 40 (83%) patients, MVO was additionally present. Segments in all patients were visually classified and 146 (19%) segments showed MVO (i.e., LGE+/MVO+), 308 (40%) segments showed LGE and no MVO (i.e., LGE+/MVO–), and 314 (41%) segments showed no LGE (i.e., LGE–). Diagnostic performance of SCS for detecting MVO segments (i.e., LGE+/MVO+ vs. LGE+/MVO–, and LGE–) showed an AUC = 0.764 and SCS cut-off value was –11.2%, resulting in a sensitivity of 78% and a specificity of 67% with a positive predictive value (PPV) of 30% and a negative predictive value (NPV) of 94% when tested in the validation group. For LGE segments (i.e., LGE+/MVO+ and LGE+/MVO– vs. LGE–) AUC = 0.848 and SCS with a cut-off value of –13.8% yielded to a sensitivity of 76%, specificity of 74%, PPV of 81%, and NPV of 70%.ConclusionSegmental strain in STEMI patients was associated with good diagnostic performance for detection of MVO+ segments and very good diagnostic performance of LGE+ segments. Segmental strain may be useful as a potential contrast-free surrogate marker to improve early risk stratification in patients after primary PCI.

Abstract
INTRODUCTION To assess the risk for COVID-19 of police officers, we are studying the seroprevalence in a cohort. The baseline cross-sectional investigation was performed before a vaccination campaign in January/February 2021, and demonstrated a seroprevalence of 12.9%. Here, we demonstrate serosurveillance results after a vaccination campaign. METHODS The cohort consists of 1022 study participants. The 3- and 6-month follow-up visits were performed in April/May and September 2021. Data on infection and vaccination rates were obtained via measuring antibodies to the nucleocapsid protein and spike protein and online questionnaires. RESULTS The mean age of the population was 41 (SD 8.8) years, 72% were male and 76% had no comorbidity. Seroconversion was identified in 1.05% of the study population at the 3-month visit and in 0.73% at the 6-month visit, resulting in an infection rate of 1.8% over a time period of 6 months. In comparison, the infection rate in the general population over the same time period was higher (3.18%, p = .018). At the 6-month visit, 77.8% of participants reported being vaccinated once and 70.5% twice; 81% had an anti-S antibody titer of >250 U/ml and 87.1% of ≥2 U/ml. No significant association between infection and job role within the department, working region, or years of experience in the job was found. Anti-spike antibody titers of vaccinated study participants showed a calculated decreasing trend 150-200 days after the second vaccine dose. CONCLUSION These data confirm the value of the vaccination campaign in an exposed group other than healthcare professionals.

Abstract
IMPORTANCE Noncardiac surgery after transcatheter aortic valve implantation (TAVI) is a clinical challenge with concerns about safety and optimal management. OBJECTIVES To evaluate perioperative risk of adverse events associated with noncardiac surgery after TAVI by timing of surgery, type of surgery, and TAVI valve performance. DESIGN, SETTING, AND PARTICIPANTS This cohort study was conducted using data from a prospective TAVI registry of patients at the tertiary care University Hospital in Bern, Switzerland. All patients undergoing noncardiac surgery after TAVI were identified. Data were analyzed from November through December 2021. EXPOSURES Timing, clinical urgency, and risk category of noncardiac surgery were assessed among patients who had undergone TAVI and subsequent noncardiac surgery. MAIN OUTCOMES AND MEASURES A composite of death, stroke, myocardial infarction, and major or life-threatening bleeding within 30 days after noncardiac surgery. RESULTS Among 2238 patients undergoing TAVI between 2013 and 2020, 300 patients (mean [SD] age, 81.8 [6.6] years; 144 [48.0%] women) underwent elective (160 patients) or urgent (140 patients) noncardiac surgery after TAVI and were included in the analysis. Of these individuals, 63 patients (21.0%) had noncardiac surgery within 30 days of TAVI. Procedures were categorized into low-risk (21 patients), intermediate-risk (190 patients), and high-risk (89 patients) surgery. Composite end points occurred within 30 days of surgery among 58 patients (Kaplan-Meier estimate, 19.7%; 95% CI, 15.6%-24.7%). There were no significant differences in baseline demographics between patients with the 30-day composite end point and 242 patients without this end point, including mean (SD) age (81.3 [7.1] years vs 81.9 [6.5] years; P = .28) and sex (25 [43.1%] women vs 119 [49.2%] women; P = .37). Timing (ie, ≤30 days from TAVI to noncardiac surgery), urgency, and risk category of surgery were not associated with increased risk of the end point. Moderate or severe prosthesis-patient mismatch (adjusted hazard ratio [aHR], 2.33; 95% CI, 1.37-3.95; P = .002) and moderate or severe paravalvular regurgitation (aHR, 3.61; 95% CI 1.25-10.41; P = .02) were independently associated with increased risk of the end point. CONCLUSIONS AND RELEVANCE These findings suggest that noncardiac surgery may be performed early after successful TAVI. Suboptimal device performance, such as prosthesis-patient mismatch and paravalvular regurgitation, was associated with increased risk of adverse outcomes after noncardiac surgery.

Abstract
BACKGROUND The comparative effectiveness of transradial (TRA) compared with transfemoral access (TFA) in acute coronary syndrome (ACS) patients undergoing complex percutaneous coronary intervention (PCI) remains unclear. METHODS Among 8,404 ACS patients in the Minimizing Adverse Haemorrhagic Events by TRansradial Access Site and Systemic Implementation of angioX (MATRIX)-Access trial, 5,233 underwent noncomplex (TRA, n=2,590 and TFA, n=2,643) and 1,491 complex PCI (TRA, n=777 and TFA, n=714). Co-primary outcomes were major adverse cardiovascular events (MACE, the composite of all-cause mortality, myocardial infarction, or stroke) and the composite of MACE and BARC type 3-5 bleeding (net adverse cardiovascular events, NACE) at 30 days. RESULTS Rates of 30-day MACE (hazard ratio [HR]:0.94; 95% confidence interval [CI]:0.72-1.22) or NACE (HR:0.89; 95% CI:0.69-1.14) did not significantly differ between groups in the complex PCI group, whereas both primary endpoints were lower (HR:0.84; 95% CI:0.70-1.00, HR:0.83; 95% CI:0.70-0.98, respectively) with TRA among noncomplex PCI patients, with negative interaction testing (Pint 0.473 and 0.666, respectively). Access-site BARC type 3 or 5 bleeding was lower with TRA, consistently among complex (HR:0.18; 95% CI:0.05-0.63) and noncomplex (HR:0.41; 95% CI:0.20-0.85) PCI patients, whereas the former group had a greater absolute risk reduction of 1.7% (number needed to treat: 59) due to their higher absolute risk. CONCLUSIONS Among ACS patients, PCI complexity does not affect the comparative efficacy and safety of TRA versus TFA, whereas the absolute risk reduction of access-site major bleeding was greater with TRA compared with TFA in complex as opposed to noncomplex PCI.

Abstract
AIMS To assess the effects of 1- or ≥3-month dual antiplatelet therapy (DAPT) in high bleeding risk (HBR) patients who received biodegradable-polymer sirolimus-eluting stents for complex percutaneous coronary intervention (PCI) and/or acute coronary syndrome (ACS). METHODS AND RESULTS In the MASTER DAPT trial, 3383 patients underwent noncomplex (abbreviated DAPT, n = 1707; standard DAPT, n = 1676) and 1196 complex (abbreviated DAPT, n = 588; standard DAPT, n = 608) PCI. Co-primary outcomes at 335 days were net adverse clinical events (NACE; composite of all-cause death, myocardial infarction, stroke, and Bleeding Academic Research Consortium [BARC] 3 or 5 bleeding events); major adverse cardiac or cerebral events (MACCE; all-cause death, myocardial infarction, and stroke); and type 2, 3, or 5 BARC bleeding.NACE and MACCE did not differ with abbreviated versus standard DAPT among patients with complex (hazard ratio [HR]: 1.03, 95% confidence interval [CI]: 0.69-1.52, and HR: 1.24, 95% CI: 0.79-1.92, respectively) and noncomplex PCI (HR: 0.90, 95% CI: 0.71-1.15, and HR: 0.91, 95% CI: 0.69-1.21; Pinteraction = 0.60 and 0.26, respectively). BARC 2, 3 or 5 was reduced with abbreviated DAPT in patients with and without complex PCI (HR: 0.64; 95% CI: 0.42-0.98, and HR: 0.70; 95% CI: 0.55-0.89; Pinteraction = 0.72). Among the 2,816 patients with complex PCI and/or ACS, NACE and MACCE did not differ and BARC 2, 3 or 5 was lower with abbreviated DAPT. CONCLUSION In HBR patients free from recurrent ischemic events at 1 month, DAPT discontinuation was associated with similar NACE and MACCE and lower bleeding rates compared with standard DAPT, regardless of PCI or patient complexity.

Abstract
BACKGROUND Mild paravalvular regurgitation (PVR) remains a frequent and underappreciated adverse event after transcatheter aortic valve implantation (TAVI) despite remarkable progress in device technology and implantation technique. AIMS This study sought to investigate the impact of mild PVR after TAVI on five-year clinical outcomes. METHODS In a prospective TAVI registry, PVR prior to discharge was retrospectively assessed in an echocardiographic core laboratory. Patients with ≥moderate PVR were excluded. Mild PVR was categorised into mild and mild-to-moderate PVR using a recently proposed unifying 5-class grading scheme. RESULTS A total of 1,128 patients undergoing TAVI between 2007 and 2015 were enrolled. Of these, 560 patients had mild PVR, including 433 with mild (5-class) PVR and 127 with mild-to-moderate PVR. Patients with mild PVR were older (83 years vs 82 years, p=0.013) and had a higher surgical risk compared to patients with none/trace PVR (STS-PROM: 6.49±4.68 vs 5.41±3.48, p<0.001). At five years, patients with mild PVR had a higher risk of mortality than those with none/trace PVR (54.6% vs 43.8%; HRadjusted 1.26, 95% CI: 1.06-1.50). When applying the 5-class grading scheme, only mild-to-moderate PVR was associated with an increased risk of mortality at five years (mild PVR: HRadjusted 1.19, 95% CI: 0.99-1.43, mild-to-moderate PVR: HRadjusted 1.56, 95% CI: 1.20-2.02). The effect of mild PVR on five-year mortality was consistent across major subgroups. CONCLUSIONS Mild PVR was associated with an increased risk of mortality at five years after TAVI. The detrimental effect was primarily driven by mild-to-moderate PVR using the 5-class grading scheme. CLINICAL TRIAL REGISTRATION https://www. CLINICALTRIALS gov. NCT01368250.

Abstract
IMPORTANCE Coronary plaques that are prone to rupture and cause adverse cardiac events are characterized by large plaque burden, large lipid content, and thin fibrous caps. Statins can halt the progression of coronary atherosclerosis; however, the effect of the proprotein convertase subtilisin kexin type 9 inhibitor alirocumab added to statin therapy on plaque burden and composition remains largely unknown. OBJECTIVE To determine the effects of alirocumab on coronary atherosclerosis using serial multimodality intracoronary imaging in patients with acute myocardial infarction. DESIGN, SETTING, AND PARTICIPANTS The PACMAN-AMI double-blind, placebo-controlled, randomized clinical trial (enrollment: May 9, 2017, through October 7, 2020; final follow-up: October 13, 2021) enrolled 300 patients undergoing percutaneous coronary intervention for acute myocardial infarction at 9 academic European hospitals. INTERVENTIONS Patients were randomized to receive biweekly subcutaneous alirocumab (150 mg; n = 148) or placebo (n = 152), initiated less than 24 hours after urgent percutaneous coronary intervention of the culprit lesion, for 52 weeks in addition to high-intensity statin therapy (rosuvastatin, 20 mg). MAIN OUTCOMES AND MEASURES Intravascular ultrasonography (IVUS), near-infrared spectroscopy, and optical coherence tomography were serially performed in the 2 non-infarct-related coronary arteries at baseline and after 52 weeks. The primary efficacy end point was the change in IVUS-derived percent atheroma volume from baseline to week 52. Two powered secondary end points were changes in near-infrared spectroscopy-derived maximum lipid core burden index within 4 mm (higher values indicating greater lipid content) and optical coherence tomography-derived minimal fibrous cap thickness (smaller values indicating thin-capped, vulnerable plaques) from baseline to week 52. RESULTS Among 300 randomized patients (mean [SD] age, 58.5 [9.7] years; 56 [18.7%] women; mean [SD] low-density lipoprotein cholesterol level, 152.4 [33.8] mg/dL), 265 (88.3%) underwent serial IVUS imaging in 537 arteries. At 52 weeks, mean change in percent atheroma volume was -2.13% with alirocumab vs -0.92% with placebo (difference, -1.21% [95% CI, -1.78% to -0.65%], P < .001). Mean change in maximum lipid core burden index within 4 mm was -79.42 with alirocumab vs -37.60 with placebo (difference, -41.24 [95% CI, -70.71 to -11.77]; P = .006). Mean change in minimal fibrous cap thickness was 62.67 μm with alirocumab vs 33.19 μm with placebo (difference, 29.65 μm [95% CI, 11.75-47.55]; P = .001). Adverse events occurred in 70.7% of patients treated with alirocumab vs 72.8% of patients receiving placebo. CONCLUSIONS AND RELEVANCE Among patients with acute myocardial infarction, the addition of subcutaneous biweekly alirocumab, compared with placebo, to high-intensity statin therapy resulted in significantly greater coronary plaque regression in non-infarct-related arteries after 52 weeks. Further research is needed to understand whether alirocumab improves clinical outcomes in this population. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03067844.

Abstract
BACKGROUND Activation of inflammatory pathways during acute myocardial infarction contributes to infarct size and left ventricular (LV) remodeling. The present prospective randomized clinical trial was designed to test the efficacy and safety of broad-spectrum anti-inflammatory therapy with a mammalian target of rapamycin (mTOR) inhibitor to reduce infarct size. DESIGN Controlled-Level EVERolimus in Acute Coronary Syndrome (CLEVER-ACS, clinicaltrials.gov NCT01529554) is a phase II randomized, double-blind, multi-center, placebo-controlled trial on the effects of a 5-day course of oral everolimus on infarct size, LV remodeling, and inflammation in patients with acute ST-elevation myocardial infarction (STEMI). Within 5 days of successful primary percutaneous coronary intervention (pPCI), patients are randomly assigned to everolimus (first 3 days: 7.5 mg every day; days 4 and 5: 5.0 mg every day) or placebo, respectively. The primary efficacy outcome is the change from baseline (defined as 12 hours to 5 days after pPCI) to 30-day follow-up in myocardial infarct size as measured by cardiac magnetic resonance imaging (CMRI). Secondary endpoints comprise corresponding changes in cardiac and inflammatory biomarkers as well as microvascular obstruction and LV volumes assessed by CMRI. Clinical events, laboratory parameters, and blood cell counts are reported as safety endpoints at 30 days. CONCLUSION The CLEVER-ACS trial tests the hypothesis whether mTOR inhibition using everolimus at the time of an acute STEMI affects LV infarct size following successful pPCI.

Abstract
BackgroundRheumatic heart disease (RHD) accounts for the highest number of deaths from valvular heart disease globally. Yet, rheumatic aortic stenosis (AS) was excluded from landmark studies investigating the safety and efficacy of transcatheter aortic valve implantation (TAVI). We aimed to describe the clinical and anatomical characteristics of patients with rheumatic AS undergoing TAVI, and to compare procedural and clinical outcomes with patients undergoing TAVI for degenerative AS.MethodsIn a prospective TAVI registry, patients with rheumatic AS were identified based on International Classification of Diseases version 10 codes and/or a documented history of acute rheumatic fever and/or the World Heart Federation criteria for echocardiographic diagnosis of RHD, and were propensity score-matched in a 1:4 ratio to patients with degenerative AS.ResultsAmong 2329 patients undergoing TAVI, 105 (4.5%) had rheumatic AS. Compared with patients with degenerative AS, patients with rheumatic AS were more commonly female, older, had higher surgical risk and more commonly suffered from multivalvular heart disease. In the unmatched cohort, both technical success (85.7% vs 85.9%, p=0.887) and 1-year cardiovascular mortality (10.0% vs 8.6%; HR 1.16, 95% CI 0.61 to 2.18, p=0.656) were comparable between patients with rheumatic and degenerative AS. In contrast, patients with rheumatic AS had lower rates of 30-day and 1-year cardiovascular mortality compared with matched patients with degenerative AS (1.9% vs 8.9%, adjusted HR (HRadj) 0.18, 95% CI 0.04 to 0.80, p=0.024; and 10.0% vs 20.3%, HRadj 0.44, 95% CI 0.24 to 0.84, p=0.012, respectively).ConclusionTAVI may be a safe and effective treatment strategy for selected elderly patients with rheumatic AS.Trial registration numberNCT01368250.

Abstract
AIMS No studies have compared Watchman 2.5 (W2.5) with Watchman FLX (FLX) devices to date. We aimed at comparing the FLX with W2.5 devices with respect to clinical outcomes, left atrial appendage (LAA) sealing properties and device-related thrombus (DRT). METHODS AND RESULTS All consecutive left atrial appendage closure (LAAC) procedures performed at two European centres between November 2017 and February 2021 were included. Procedure-related complications and net adverse cardiovascular events (NACE) at 6 months after LAAC were recorded. At 45-day computed tomography (CT) follow-up, intra- (IDL) and peri- (PDL) device leak, residual patent neck area (RPNA), and DRT were assessed by a Corelab. Out of 144 LAAC consecutive procedures, 71 and 73 interventions were performed using W2.5 and FLX devices, respectively. There were no differences in terms of procedure-related complications (4.2% vs. 2.7%, P = 0.626). At 45-day CT, the FLX was associated with lower frequency of IDL [21.3% vs. 40.0%; P = 0.032; odds ratio (OR): 0.375; 95% confidence interval (CI): 0.160-0.876; P = 0.024], similar rate of PDL (29.5% vs. 42.0%; P = 0.170), and smaller RPNA [6 (0-36) vs. 40 (6-115) mm2; P = 0.001; OR: 0.240; 95% CI: 0.100-0.577; P = 0.001] compared with the W2.5 group. At 45 days, rate of DRT as detected by CT and/or transoesophageal echocardiography (TOE), was higher with W2.5 (6.0% vs. 0%, P = 0.045). At 6-month follow-up, NACE did not differ between groups. CONCLUSIONS In this cohort of consecutive LAACs, FLX as compared to W2.5, was associated with similar procedure-related complications and 6-month NACE, but with improved LAA neck coverage, and lower IDL and DRT.

Abstract
Background In the GLOBAL LEADERS trial, ticagrelor monotherapy beyond 1 month compared with standard antiplatelet regimens after coronary stent implantation did not improve outcomes at intention‐to‐treat analysis. Considerable differences in treatment adherence between the experimental and control groups may have affected the intention‐to‐treat results. In this reanalysis of the GLOBAL LEADERS trial, we compared the experimental and control treatment strategies in a per‐protocol analysis of patients who did not deviate from the study protocol. Methods and Results Baseline and postrandomization information were used to classify whether and when patients were deviating from the study protocol. With logistic regressions, we derived time‐varying inverse probabilities of nondeviation from protocol to reconstruct the trial population without protocol deviation. The primary end point was a composite of all‐cause mortality or nonfatal Q‐wave myocardial infarction at 2 years. At 2‐year follow‐up, 1103 (13.8%) of 7980 patients in the experimental group and 785 (9.8%) of 7988 patients in the control group qualified as protocol deviators. At per‐protocol analysis, the rate ratio for the primary end point was 0.88 (95% CI, 0.75–1.03; P=0.10) on the basis of 274 versus 325 events in the experimental versus control group. The rate ratio for the key safety end point of major bleeding was 1.00 (95% CI, 0.79–1.26; P=0.99). The per‐protocol and intention‐to‐treat effect estimates were overall consistent. Conclusions Among patients who complied with the study protocol in the GLOBAL LEADERS trial, ticagrelor plus aspirin for 1 month followed by ticagrelor monotherapy was not superior to 1‐year standard dual antiplatelet therapy followed by aspirin alone at 2 years after coronary stenting.

Abstract
Background Increased left ventricular afterload resulting from severe aortic stenosis (AS) leads to progressive cardiac remodeling. Left atrial enlargement (LAE) is an early manifestation in a series of maladaptive changes and may affect clinical outcomes after valvular replacement therapy. The aim of this study is to determine the impact of LAE on clinical outcomes in symptomatic patients with severe AS undergoing transcatheter aortic valve implantation (TAVI). Methods In a prospective single‐center TAVI registry, we analyzed LA dimensions measured by echocardiography before intervention. Patients with atrial fibrillation or concomitant mitral valve disease were excluded. LAE was defined as indexed LA volume >34 ml/m2. The primary endpoint was cardiovascular death (CVD) at 1 year. Results Among 1663 patients undergoing TAVI between August 2007 and December 2016, 768 (46.2%) were eligible for the present analysis and 486 patients had LAE. The prevalence of LAE was higher in males (68.3%) as compared to females (58.8%). Patients with LAE were older (82.3 ± 6.7 years vs. 80.0 ± 6.4 years) and had a higher STS‐PROM score (6.1 ± 4.7% vs. 4.7 ± 2.9%). After adjustment, patients with LAE had an increased risk of CVD at 1‐year compared to patients with normal LA dimensions (49 [10.4%] vs. 8 [2.9%]; HRadj, 3.52; 95% CI, 1.66–7.44)]. In multivariable analysis, LAE was independently associated with an increased risk of CVD at 1‐year (HRadj, 3.52; 95% CI, 1.66–7.44). Conclusions LAE secondary to AS was documented in a significant proportion of patients undergoing TAVI and was associated with a more than threefold increased risk of CVD at 1‐year.

Abstract
BACKGROUND Definitions of periprocedural myocardial infarction (MI) differ with respect to biomarker threshold as well as ancillary criteria for myocardial ischemia and are limited in terms of validation. OBJECTIVES This study evaluated the frequency and impact of periprocedural MI by using various MI definitions among patients with chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI). METHODS Between 2010 and 2018, periprocedural MIs were assessed according to the third and fourth Universal Definition of Myocardial Infarction (UDMI), Academic Research Consortium-2 (ARC-2), and Society for Cardiovascular Angiography and Interventions (SCAI) criteria based on high-sensitivity troponin in patients with CCS undergoing PCI enrolled into the Bern PCI registry. The primary endpoint was cardiac death at 1 year. RESULTS Among 4,404 patients with CCS, periprocedural MI defined by the third UDMI, fourth UDMI, ARC-2, and SCAI were observed in 18.0%, 14.9%, 2.0%, and 2.0% of patients, respectively. Among patients with periprocedural MI defined by the third UDMI, fourth UDMI, ARC-2, and SCAI, cardiac mortality at 1 year was 2.9%, 3.0%, 5.8%, and 10.0%. The ARC-2 (HR: 3.90; 95% CI: 1.54-9.93) and SCAI (HR: 7.66; 95% CI: 3.64-16.11) were more relevant compared with the third UDMI (HR: 1.76; 95% CI: 1.04-3.00) and fourth UDMI (HR: 1.93; 95% CI: 1.11-3.37) for cardiac death at 1 year. CONCLUSIONS Among patients with CCS undergoing PCI, periprocedural MI defined according to the ARC-2 and SCAI criteria was 7 to 9 times less frequent compared with the third and fourth UDMI. Periprocedural MI defined by using the ARC-2 and SCAI were more prognostic for cardiac death at 1 year compared with the third and fourth UDMI. (CARDIOBASE Bern PCI Registry; NCT02241291).

Abstract
BACKGROUND Ascending aortic root anatomy is routinely evaluated on pre-procedural multi-detector computed tomography (MDCT). However, its clinical significance has not been adequately studied. We aimed to investigate the impact of the sinus of Valsalva (SOV) dimension on clinical outcomes in patients undergoing transcatheter aortic valve implantation (TAVI). METHODS In a prospective TAVI registry, we retrospectively assessed SOV dimensions by pre-procedural MDCT. Patients were stratified according to tertiles of SOV diameter indexed to body surface area (SOVi). The primary endpoint was all-cause mortality at 1 year. RESULTS Among 2066 consecutive patients undergoing TAVI between August 2007 and June 2018, 1554 patients were eligible for the present analysis. Patients in the large SOVi group were older (83 ± 6 vs 82 ± 6 vs 81 ± 6; P < .001) and had a higher Society of Thoracic Surgeons Predicted Risk of Mortality (6.3 ± 3.8 vs 5.1 ± 3.1 vs 4.9 ± 3.5; P < .001) than those in the other groups. Patients in the large SOVi group had a higher incidence of moderate or severe paravalvular regurgitation (11.9% vs 4.5% vs 3.5%; P < .001). At 1 year, a large SOVi was independently associated with an increased risk of mortality (HR: 1.62; 95% CI: 1.19-2.21; P = .002) and major or life-threatening bleeding (HR: 1.30; 95% CI: 1.02-1.65; P = .035). CONCLUSIONS Dilatation of the aortic root at the SOV was associated with adverse outcomes after TAVI. The assessment of the aortic root should be integrated into the risk stratification system in patients undergoing TAVI.

Abstract
BACKGROUND The radial artery is recommended by international guidelines as the default vascular access in patients with acute coronary syndromes (ACS) managed invasively. However, crossover from radial to femoral access is required in 4-10% of cases and has been associated with worse outcomes. No standardised algorithm exists to predict the risk of radial crossover. AIMS We sought to derive and externally validate a risk score to predict radial crossover in patients with ACS managed invasively. METHODS The derivation cohort consisted of 4,197 patients with ACS undergoing invasive management via the randomly allocated radial access from the MATRIX trial. Using logistic regression, we selected predictors of radial crossover and developed a numerical risk score. External validation was accomplished among 3,451 and 491 ACS patients managed invasively and randomised to radial access from the RIVAL and RIFLE-STEACS trials, respectively. RESULTS The MATRIX score (age, height, smoking, renal failure, prior coronary artery bypass grafting, ST-segment elevation myocardial infarction, Killip class, radial expertise) showed a c-index for radial crossover of 0.71 (95% CI: 0.67-0.75) in the derivation cohort. Discrimination ability was modest in the RIVAL (c-index: 0.64; 95% CI: 0.59-0.67) and RIFLE-STEACS (c-index: 0.66; 95% CI: 0.57-0.75) cohorts. A cut-off of ≥41 points was selected to identify patients at high risk of radial crossover. CONCLUSIONS The MATRIX score is a simple eight-item risk score which provides a standardised tool for the prediction of radial crossover among patients with ACS managed invasively. This tool can assist operators in anticipating and better addressing difficulties related to transradial procedures, potentially improving outcomes.

Abstract
AIMS Underrepresentation of migrants, women, and older adults in cardiovascular disease (CVD) trials may contribute to disparate care and survival. Among patients who underwent percutaneous coronary intervention (PCI), we aimed to investigate the associations of (i) underrepresented groups with major adverse cardiac events (MACE), CVD mortality, and non-CVD mortality, (ii) underrepresented groups with cardiac rehabilitation (CR) uptake, and (iii) CR uptake with outcomes. METHODS AND RESULTS We included 15 211 consecutive patients from the CARDIOBASE Bern PCI registry (2009-18). In multi-state models comparing transition probabilities of events, sex was not associated with increased risk of any event. For each year increase in age, the increased risk of non-CVD and CVD mortality was 8% [95% confidence interval (CI) 6-9%]. Being migrant was associated with a lower risk of non-CVD mortality [hazard ratio (HR) (95% CI) 0.49 (0.27-0.90)] but not with CVD mortality. In logistic regression analysis, CR uptake was lower among women [odds ratio (95% CI) = 0.72 (0.57-0.86)] and older adults [0.32 (0.27-0.38)], but not among migrants. In cox regression, CR was independently associated with lower all-cause [HR (95% CI) = 0.12 (0.03-0.37)] and CVD mortality [0.1 (0.02-0.7)], but not with MACE [1.08 (0.8-1.4)]. CONCLUSION Among underrepresented groups undergoing PCI, age, but not migration status nor sex, contributed to disparities in mortality. Migrant status did not result in lower attendance of CR. Considering the protective associations of CR on CVD mortality independent of age, sex, and migration status, the lower uptake in women and older adults is noteworthy.

Abstract
BACKGROUND The identification of bleeding risk factors in patients undergoing percutaneous coronary intervention (PCI) is essential to inform subsequent management. Whether clinical presentation per se affects bleeding risk after PCI remains unclear. AIMS We aimed to assess whether clinical presentation per se predisposes to bleeding in patients undergoing PCI and if the Academic Research Consortium (ARC) High Bleeding Risk (HBR) criteria perform consistently in acute (ACS) and chronic (CCS) coronary syndrome patients. METHODS Consecutive patients undergoing PCI from the Bern PCI Registry were stratified by clinical presentation. Bleeding events at one year were compared in ACS versus CCS patients, and the originally defined ARC-HBR criteria were assessed. RESULTS Among 16,821 patients, 9,503 (56.5%) presented with ACS. At one year, BARC 3 or 5 bleeding occurred in 4.97% and 3.60% of patients with ACS and CCS, respectively. After adjustment, ACS remained associated with higher BARC 3 or 5 bleeding risk (adjusted HR 1.21, 95% CI: 1.01-1.43; p=0.034), owing to non-access site-related occurrences, which accrued mainly within the first 30 days after PCI. The ARC-HBR score had lower discrimination among ACS compared with CCS patients, and its performance slightly improved when ACS was computed as a minor criterion. CONCLUSIONS ACS presentation per se predicts one-year major bleeding risk after PCI. The ARC-HBR score discrimination appeared lower in ACS than CCS, and its overall performance improved numerically when ACS was computed as an additional minor risk criterion.

Abstract
Background: No study has so far compared Amulet with the new Watchman FLX in terms of residual left atrial appendage (LAA) patency or clinical outcomes in patients undergoing percutaneous LAA closure (LAAC). Methods: In the investigator-initiated SWISS APERO trial, patients undergoing LAAC were randomized (1:1) open-label to receive Amulet or Watchman 2.5 or FLX (Watchman) across 8 European centres. The primary endpoint was the composite of justified crossover to a non-randomized device during LAAC procedure or residual LAA patency detected by cardiac computed tomography angiography (CCTA) at 45 days. The secondary endpoints included procedural complications, device related thrombus (DRT), peridevice leak (PDL) at transesophageal echocardiography (TEE) and clinical outcomes at 45 days. Results: Between June 2018, and May 2021, 221 patients were randomly assigned to Amulet (111 [50.2%]) or Watchman (110 [49.8%]), of whom 25 (22.7%) patients included before October 2019 received Watchman 2.5, and 85 (77.3%) patients received Watchman FLX. The primary endpoint was assessable in 205 (92.8%) patients and occurred in 71 (67.6%) Amulet and 70 (70.0%) Watchman patients respectively (risk ratio [RR] 0.97 [95% CI 0.80- 1.16]; P=0.713). A single justified cross-over occurred in an Amulet patient who fulfilled LAA patency criteria at 45-day CCTA. Major procedure related complications occurred more frequently in the Amulet group (9.0% vs. 2.7%; P=0.047), owing to more frequent bleeding (7.2% vs.1.8%). At 45 days, the PDL rate at TEE was higher with Watchman than Amulet (27.5% vs. 13.7%, p=0.020), albeit none was major (i.e. > 5 mm), whereas DRT was detected in 1 (0.9%) patient with Amulet and 3 (3.0%) patients with Watchman at CCTA and in 2 (2.1%) and 5 (5.5%) patients at TEE, respectively. Clinical outcomes at 45 days did not differ between the groups. Conclusions: Amulet was not associated with lower rate of the composite of crossover or residual LAA patency compared with Watchman at 45-day CCTA. Amulet, was however associated with lower PDL rates at TEE, higher procedural complications and similar clinical outcomes at 45 days compared with Watchman. The clinical relevance of CCTA-detected LAA patency requires further investigation. Clinical Trial Registration: URL https://clinicaltrials.gov Unique Identifier NCT03399851.

Abstract
BACKGROUND Current guidelines favor transcatheter aortic valve implantation (TAVI) over surgical aortic valve replacement in patients with porcelain aorta (PAo). The clinical relevance of PAo in patients undergoing TAVI is however incompletely understood. The purpose of this study is to evaluate clinical outcome of patients with PAo undergoing TAVI. METHODS Consecutive patients undergoing TAVI were enrolled in a prospective single-center registry. Presence of PAo was evaluated by ECG-gated multi-slice computed tomography prior to the intervention. The primary endpoint was disabling stroke. RESULTS Among 2199 patients (mean age, 82.0 ± 6.3 years; 1135 females [51.6%]) undergoing TAVI between August 2007 and December 2019, 114 patients (5.2%) met VARC-2 criteria for PAo. Compared to individuals without PAo, patients with PAo were younger (79.4 ± 7.4 years vs. 82.1 ± 6.2 years; p < 0.001), had a lower left ventricular ejection fraction (51.8 ± 14.9% vs. 55.3 ± 14.2%; p = 0.009) and higher STS-PROM Scores (6.5 ± 4.3% vs. 4.9 ± 3.4%; p < 0.001). At 1 year, disabling stroke occurred more often in patients with PAo (7.2%) than in those without (3.0%) (HRadj, 2.49; 95% CI, 1.12-5.55). The risk difference emerged within 30 days after TAVI (HRadj, 3.70; 95% CI, 1.52-9.03), and was driven by a high PAo-associated risk of disabling stroke in patients with alternative access (HRadj, 5.79; 95% CI, 1.38-24.3), not in those with transfemoral (HRadj, 1.47; 95% CI 0.45-4.85). CONCLUSIONS TAVI patients with PAo had a more than three-fold increased risk of periprocedural disabling stroke compared to patients with no PAo. The difference was driven by a higher risk of stroke in patients treated by alternative access.

Abstract
BACKGROUND The appropriate duration of dual antiplatelet therapy in patients at high risk for bleeding after the implantation of a drug-eluting coronary stent remains unclear. METHODS One month after they had undergone implantation of a biodegradable-polymer sirolimus-eluting coronary stent, we randomly assigned patients at high bleeding risk to discontinue dual antiplatelet therapy immediately (abbreviated therapy) or to continue it for at least 2 additional months (standard therapy). The three ranked primary outcomes were net adverse clinical events (a composite of death from any cause, myocardial infarction, stroke, or major bleeding), major adverse cardiac or cerebral events (a composite of death from any cause, myocardial infarction, or stroke), and major or clinically relevant nonmajor bleeding; cumulative incidences were assessed at 335 days. The first two outcomes were assessed for noninferiority in the per-protocol population, and the third outcome for superiority in the intention-to-treat population. RESULTS Among the 4434 patients in the per-protocol population, net adverse clinical events occurred in 165 patients (7.5%) in the abbreviated-therapy group and in 172 (7.7%) in the standard-therapy group (difference, -0.23 percentage points; 95% confidence interval [CI], -1.80 to 1.33; P<0.001 for noninferiority). A total of 133 patients (6.1%) in the abbreviated-therapy group and 132 patients (5.9%) in the standard-therapy group had a major adverse cardiac or cerebral event (difference, 0.11 percentage points; 95% CI, -1.29 to 1.51; P = 0.001 for noninferiority). Among the 4579 patients in the intention-to-treat population, major or clinically relevant nonmajor bleeding occurred in 148 patients (6.5%) in the abbreviated-therapy group and in 211 (9.4%) in the standard-therapy group (difference, -2.82 percentage points; 95% CI, -4.40 to -1.24; P<0.001 for superiority). CONCLUSIONS One month of dual antiplatelet therapy was noninferior to the continuation of therapy for at least 2 additional months with regard to the occurrence of net adverse clinical events and major adverse cardiac or cerebral events; abbreviated therapy also resulted in a lower incidence of major or clinically relevant nonmajor bleeding.
