    Abstract Objectives: The ELANA® Heart Bypass creates a standardized sutureless anastomosis. Hereby, we investigate the influence of arteriotomy and graft size on coronary hemodynamics.
    Methods: A computational fluid dynamics (CFD) model was developed. Arteriotomy size (standard 1.43 mm
    Results: The current size ELANA (arteriotomy 1.43 mm
    Conclusion: The ratio between the required minimal coronary diameter for application and the ELANA arteriotomy size effectuates a pressure drop that could be clinically relevant. Additional research and eventual lengthening of the anastomosis is advised.

    Abstract Background: The effect of administering a crushed prasugrel loading dose is uncertain in patients presenting with a large myocardial infarction and ST-segment elevation myocardial infarction (STEMI).
    Aims: The aim of this study was to investigate if patients with a large myocardial infarction may benefit from prehospital administration of a crushed prasugrel loading dose.
    Methods: Patients from the CompareCrush trial with an available ambulance electrocardiography (ECG) were included in the study. An independent core laboratory confirmed a prehospital large myocardial area. We compared pre- and postprocedural angiographic markers, including Thrombolysis in Myocardial Infarction (TIMI) 3 flow in the infarct-related artery, high thrombus burden, and myocardial blush grade 3, in STEMI patients with and without a prehospital large myocardial area.
    Results: Ambulance ECG was available for 532 patients, of whom 331 patients were identified with a prehospital large myocardial area at risk. Crushed prasugrel significantly improved postprocedural TIMI 3 flow rates in STEMI patients with a prehospital large myocardial area at risk (92% vs 79%, odds ratio [OR] 3.00, 95% confidence interval [CI]: 1.50-6.00) but not in STEMI patients without a prehospital large myocardial area at risk (91% vs 95%, OR 0.47, 95% CI: 0.14-1.57; p
    Conclusions: Administration of crushed prasugrel may improve postprocedural TIMI 3 flow in STEMI patients with signs of a large myocardial area at risk on the ambulance ECG. The practice of crushing tablets of prasugrel loading dose might, therefore, represent a safe, fast and cost-effective strategy to improve myocardial reperfusion in this high-risk STEMI subgroup undergoing primary percutaneous coronary intervention.

    Abstract Objective: Patients with acute coronary syndrome (ACS) remain at high risk for recurrent ischaemic and bleeding events during follow-up. Our study aimed to quantify and compare the impact of these adverse events on quality of life (QoL).
    Methods: Data from patients with ACS prospectively enrolled in the FORCE-ACS registry between January 2015 and December 2019 were used for this study. The primary ischaemic and bleeding events of interest were hospital readmission for ACS and Bleeding Academic Research Consortium type 2 or 3 bleeding during 12 months follow-up. QoL was measured using the EQ-5D Visual Analogue Scale (VAS) score and the 12-item Short Form Survey version 2 derived Physical Component Summary (PCS) and Mental Health Component Summary (MCS) scores at 12 months follow-up.
    Results: In total, 3339 patients (mean age 66.8 years, 27.9% women) were included. During follow-up, ischaemic events occurred in 202 patients (6.0%) and bleeding events in 565 patients (16.9%). After adjustment for demographic and clinical characteristics, ischaemic events remained independently associated with lower QoL regardless of metric used. Bleeding was also independently associated with lower EQ-5D VAS and PCS scores, but not with a lower MCS score. The QoL decrement associated with ischaemic events was numerically larger than the decrement associated with bleeding.
    Conclusions: Ischaemic and bleeding events remain prevalent and are independently associated with lower QoL at 12 months follow-up in patients previously admitted for ACS. The incidence and impact of these adverse events should be considered when balancing individual ischaemic and bleeding risks.

    Abstract Background: Direct stenting (DS) compared with conventional stenting (CS) after balloon predilatation may reduce distal embolization during percutaneous coronary intervention (PCI), thereby improving tissue reperfusion. In contrast, DS may increase the risk of stent underexpansion and target lesion failure.
    Methods: In this sub-study of the randomized COMPARE CRUSH trial (NCT03296540), we reviewed the efficacy of DS versus CS in a cohort of contemporary, pretreated ST-segment elevation myocardial infarction (STEMI) patients undergoing primary PCI. We compared DS versus CS, assessing (1) stent diameter in the culprit lesion, (2) thrombolysis in myocardial infarction (TIMI) flow in the infarct-related artery post-PCI and complete ST-segment resolution (STR) one-hour post-PCI, and (3) target lesion failure at one year. For proportional variables, propensity score weighting was applied to account for potential treatment selection bias.
    Results: This prespecified sub-study included 446 patients, of whom 189 (42%) were treated with DS. Stent diameters were comparable between groups (3.2 ± 0.5 vs. 3.2 ± 0.5 mm,
    Conclusion: In this contemporary pretreated STEMI cohort, we found no difference in early myocardial reperfusion outcomes between DS and CS. Moreover, DS seemed comparable to CS in terms of stent diameter and one-year vessel patency.

    Abstract Background: Drug eluting stents with biodegradable polymers have been developed to address the risk of very late adverse events. Long-term comparison data between the biodegradable polymer-coated biolimus-eluting stent (BES; Nobori®) and the second-generation durable polymer-coated everolimus-eluting stent (EES; XIENCE V® or XIENCE PRIME® or PROMUS™) in diabetic patients are scarce.
    Methods: The COMPARE II trial was an investigator-initiated, multicenter, open-label, randomized, all-comers trial which assigned patients undergoing percutaneous coronary intervention (PCI) in a 2:1 fashion to either BES or EES. We analyzed the safety and efficacy outcomes in diabetic patients at 5 year follow-up. The primary pre-specified composite endpoint major adverse cardiac event (MACE) was defined as cardiac death, non-fatal target-vessel myocardial infarction (TV-MI), or clinically indicated target vessel revascularization (CD-TVR).
    Results: Out of 2707 study patients, 588 were diabetics (21.7%) of whom 391 were treated with BES and 197 with EES. At 5 years follow-up, MACE occurred in 87 patients (22.2%) in the BES group and in 34 patients (17.2%) in the EES group (p = .34). Other safety and efficacy endpoints did not differ between stent groups.
    Conclusions: At 5 years follow-up, no differences in terms of MACE as well as all analyzed safety and efficacy measures, including stent thrombosis, between the biodegradable polymer-coated BES and the durable polymer-coated EES in diabetic patients were observed.
