Frequency of periprocedural myocardial injury and infarction stratified by cardiac troponin I and cardiac troponin T. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2024:S1553-8389(24)00491-3. [PMID: 38789340 DOI: 10.1016/j.carrev.2024.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 04/13/2024] [Accepted: 05/17/2024] [Indexed: 05/26/2024]
Abstract
BACKGROUND There are different definitions of periprocedural myocardial infarction (PPMI) both in terms of thresholds for cardiac biomarkers and the ancillary criteria for myocardial ischemia. Cardiac Troponin I (cTnI) and cardiac Troponin T (cTnT) are used interchangeably to diagnose PPMI. OBJECTIVES This study evaluated the frequency of periprocedural myocardial injury and infarction as defined by the Society of Cardiovascular Angiography & Interventions (SCAI), the Academic Research Consortium-2 (ARC-2), and the 4th Universal definition of MI (4UDMI) stratified using cTnT versus cTnI, among patients with chronic coronary syndrome (CCS) and unstable angina. RESULTS Among 830 patients, PPMI rates according to the SCAI, ARC2 and 4UDMI criteria were 4.34 %, 2.05 %, and 4.94 % respectively, with higher rates seen for all definitions when using cTnI versus cTnT (SCAI: 9.84 % vs. 1.91 %, p < 0.001; ARC 2: 3.15 % vs. 1.56 %, p = 0.136; and 4UDMI 5.91 % vs. 4.51 %, p = 0.391). Minor and major periprocedural myocardial injury was respectively observed in 58.31 % and 27.10 % of patients, with rates of both significantly higher when using cTnI versus cTnT (Minor: 69.29 % vs. 53.47 %, p < 0.001, Major: 49.21 % vs. 17.36 %, p < 0.001). CONCLUSIONS Among patients with CCS and unstable angina, PPMIs defined by SCAI occurred more frequently when using cTnI as opposed to cTnT, whereas the type of troponin had no impact on the incidence of PPMIs according to the ARC-2 and 4UDMI.

Temporal changes in coronary plaque as assessed by an artificial intelligence-based optical coherence tomography: from the first-in-human trial on DREAMS 3G scaffold. Eur Heart J Cardiovasc Imaging 2024; 25:491-497. [PMID: 37936296 DOI: 10.1093/ehjci/jead299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 10/06/2023] [Accepted: 10/15/2023] [Indexed: 11/09/2023] Open
Abstract
AIMS The aim of the study is to assess the impact of the baseline plaque composition on the DREAMS 3G luminal late loss and to compare the serial plaque changes between baseline and 6 and 12 months (M) follow-up. METHODS AND RESULTS A total of 116 patients were enrolled in the BIOMAG-I trial. Patients were imaged with optical coherence tomography (OCT) pre- and post-DREAMS 3G implantation and at 6 and 12 M. OCTPlus software uses artificial intelligence to assess composition (i.e. lipid, calcium, and fibrous tissue) of the plaque. The differences between the OCT-derived minimum lumen area (MLA) post-percutaneous coronary intervention and 12 M were grouped into three terciles. Patients with larger MLA differences at 12 M (P = 0.0003) had significantly larger content of fibrous tissue at baseline. There was a reduction of 24.8% and 20.9% in lipid area, both P < 0.001, between the pre-DREAMS 3G OCT and the 6 and 12 M follow-up. Conversely, the fibrous tissue increased by 48.4% and 36.0% at 6 and 12 M follow-up, both P < 0.001. CONCLUSION The larger the fibrous tissue in the lesion at baseline, the larger the luminal loss seen at 6 and 12 M. Following the implantation of DREAMS 3G, favourable healing of the vessel coronary wall occurs as shown by a decrease in the lipid area and an increase in fibrous tissue.

J Cardiovasc Transl Res 2023; 16:1135-1143. [PMID: 37264295 DOI: 10.1007/s12265-023-10400-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 05/17/2023] [Indexed: 06/03/2023]
Abstract
The optimal duration of dual antiplatelet therapy (DAPT) in high bleeding risk (HBR) patients undergoing percutaneous coronary intervention (PCI) with implantation of the Orsiro Mission stent remains unclear. The BIOFLOW-DAPT (clinicaltrials.gov, NCT04137510) trial is a prospective, multi-center, randomized controlled study designed to assess the safety of the Orsiro Mission versus the Resolute Onyx stent in HBR patients. Patients are treated with DAPT (aspirin and a P2Y12 inhibitor) for 1 month, followed by a single antiplatelet therapy (SAPT). The primary endpoint is the composite of cardiac death, myocardial infarction, and definite or probable stent thrombosis at 1 year. With a final sample size of 1948 HBR patients, this study is powered to assess the noninferiority of the Orsiro Mission stent with respect to the primary study endpoint. The BIOFLOW-DAPT is the first randomized clinical trial investigating 1-month DAPT duration in HBR patients after implantation of the Orsiro Mission stent.Trial Registration: ClinicalTrials.gov number, NCT04137510 Study design and key features. Patient selection starts before the index PCI, when consented patients will be randomized to the Orsiro Mission or the Resolute Onyx stent with mandated 1-month DAPT. At 1 month, eligibility is reassessed and if met, patients will discontinue DAPT and continue with P2Y12 inhibitor or aspirin monotherapy. PCI, percutaneous coronary intervention; DAPT, dual antiplatelet therapy; DES, drug-eluting stent; HBR, high bleeding risk; P2Y12i, P2Y12 inhibitor; ST, stent thrombosis.

Abstract
BACKGROUND Limited information is available on the comparative efficacy and safety of different stent platforms in patients at high bleeding risk undergoing an abbreviated dual antiplatelet therapy duration after percutaneous coronary intervention (PCI). The aim of this study was to compare the safety and effectiveness of the biodegradable-polymer sirolimus-eluting stent with the durable-polymer zotarolimus-eluting stent in patients at high bleeding risk receiving 1 month of dual antiplatelet therapy after PCI. METHODS The Bioflow-DAPT Study is an international, randomized, open-label trial conducted at 52 interventional cardiology hospitals in 18 countries from February 24, 2020, through September 20, 2021. Patients with a clinical indication to PCI because of acute or chronic coronary syndrome who fulfilled 1 or more criteria for high bleeding risk were eligible for enrollment. Patients were randomized to receive either biodegradable-polymer sirolimus-eluting stents or durable-polymer, slow-release zotarolimus-eluting stents after successful lesion preparation, followed by 1 month of dual antiplatelet therapy and thereafter single antiplatelet therapy. The primary outcome was the composite of death from cardiac causes, myocardial infarction, or stent thrombosis at 1 year, and was powered for noninferiority, with an absolute margin of 4.1% at 1-sided 5% alpha. RESULTS A total of 1948 patients at high bleeding risk were randomly assigned (1:1) to receive biodegradable-polymer sirolimus-eluting stents (969 patients) or durable-polymer zotarolimus-eluting stents (979 patients). At 1 year, the primary outcome was observed in 33 of 969 patients (3.6%) in the biodegradable-polymer sirolimus-eluting stent group and in 32 of 979 patients (3.4%) in the durable-polymer zotarolimus-eluting stent group (risk difference, 0.2 percentage points; upper boundary of the 1-sided 95% CI, 1.8; upper boundary of the 1-sided 97.5% CI, 2.1; P<0.0001 for noninferiority for both tests). CONCLUSIONS Among patients at high risk for bleeding who received 1 month of dual antiplatelet therapy after PCI, the use of biodegradable-polymer sirolimus-eluting stents was noninferior to the use of durable-polymer zotarolimus-eluting stents with regard to the composite of death from cardiac causes, myocardial infarction, or stent thrombosis.

Abstract
BACKGROUND The impact of intracoronary imaging on outcomes, after provisional versus dual-stenting for bifurcation left main (LM) lesions, is unknown. OBJECTIVES We investigated the effect of intracoronary imaging in the EBC MAIN trial (European Bifurcation Club LM Coronary Stent study). METHODS Four hundred and sixty-seven patients were randomized to dual-stenting or a stepwise provisional strategy. Four hundred and fifty-five patients were included. Intravascular ultrasound (IVUS) or optical coherence tomography (OCT) was undertaken at the operator's discretion. The primary endpoint was death, myocardial infarction or target vessel revascularization at 1-year. RESULTS Intracoronary imaging was undertaken in 179 patients (39%; IVUS = 151, OCT = 28). As a result of IVUS findings, operators reintervened in 42 procedures. The primary outcome did not differ with intracoronary imaging versus angiographic-guidance (17% vs. 16%; odds ratio [OR]: 0.92 (95% confidence interval [CI]: 0.51-1.63) p = 0.767), nor for reintervention based on IVUS versus none (14% vs. 16%; OR: 0.88 [95% CI: 0.32-2.43] p = 0.803), adjusted for syntax score, lesion calcification and ischemic symptoms. With angiographic-guidance, primary outcome events were more frequent with dual versus provisional stenting (21% vs. 10%; adjusted OR: 2.11 [95% CI: 1.04-4.30] p = 0.039). With intracoronary imaging, there were numerically fewer primary outcome events with dual versus provisional stenting (13% vs. 21%; adjusted OR: 0.56 [95% CI: 0.22-1.46] p = 0.220). CONCLUSIONS In EBC MAIN, the primary outcome did not differ with intracoronary imaging versus none. However, in patients with angiographic-guidance, outcomes were worse with a dual-stent than provisional strategy When intracoronary imaging was used, there was a trend toward better outcomes with the dual-stent than provisional strategy.

Abstract
BACKGROUND The third-generation coronary sirolimus-eluting magnesium scaffold, DREAMS 3G, is a further development of the DREAMS 2G (commercial name Magmaris), aiming to provide performance outcomes similar to drug-eluting stents (DES). AIMS The BIOMAG-I study aims to assess the safety and performance of this new-generation scaffold. METHODS This is a prospective, multicentre, first-in-human study with clinical and imaging follow-up scheduled at 6 and 12 months. The clinical follow-up will continue for 5 years. RESULTS A total of 116 patients with 117 lesions were enrolled. At 12 months, after completion of resorption, in-scaffold late lumen loss was 0.24±0.36 mm (median 0.19, interquartile range 0.06-0.36). The minimum lumen area was 4.95±2.24 mm² by intravascular ultrasound and 4.68±2.32 mm² by optical coherence tomography. Three target lesion failures were reported (2.6%, 95% confidence interval: 0.9-7.9), all clinically driven target lesion revascularisations. Cardiac death, target vessel myocardial infarction and definite or probable scaffold thrombosis were absent. CONCLUSIONS Data at the end of the resorption period of DREAMS 3G showed that the third-generation bioresorbable magnesium scaffold is clinically safe and effective, making it a possible alternative to DES.

Abstract
BACKGROUND Bioresorbable scaffolds have been developed to overcome the limitations of drug-eluting stents and to reduce long-term adverse events. AIMS We aimed to assess the long-term safety and efficacy of a sirolimus-eluting resorbable magnesium scaffold to ensure its safe rollout into clinical routine. METHODS BIOSOLVE-IV is a prospective, international, multicentre registry including more than 100 centres in Europe, Asia, and Asia-Pacific. Enrolment started directly after the commercialisation of the device. Follow-up assessments are scheduled at 6 and 12 months, and annually for up to 5 years; we herein report the 24-month outcomes. RESULTS Overall, 2,066 patients with 2,154 lesions were enrolled. Patients were 61.9±10.5 years old, 21.6% had diabetes, and 18.5% had non-ST-elevation myocardial infarction (NSTEMI). Lesions were 14.8±4.0 mm long with a reference vessel diameter of 3.2±0.3 mm. Device and procedure success were 97.5%, and 99.1%, respectively. The 24-month target lesion failure (TLF) rate was 6.8%, mainly consisting of clinically driven target lesion revascularisations (6.0%). Patients with NSTEMI had significantly higher TLF rates than those without (9.3% vs 6.2%; p=0.025), whereas there were no significant differences observed for patients with diabetes or with type B2/C lesions (a 24-month TLF rate of 7.0% and 7.9%, respectively). The 24-month rate of definite or probable scaffold thrombosis was 0.8%. Half of the scaffold thromboses occurred after premature discontinuation of antiplatelet/anticoagulation therapy, and only one scaffold thrombosis occurred beyond the 6-month follow-up, on day 391. CONCLUSIONS The BIOSOLVE-IV registry showed good safety and efficacy outcomes, confirming a safe rollout of the Magmaris into clinical practice.

Safety and performance of the third-generation drug-eluting resorbable coronary magnesium scaffold system in the treatment of subjects with de novo coronary artery lesions: 6-month results of the prospective, multicenter BIOMAG-I first-in-human study. EClinicalMedicine 2023; 59:101940. [PMID: 37113674 PMCID: PMC10126775 DOI: 10.1016/j.eclinm.2023.101940] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 03/16/2023] [Accepted: 03/16/2023] [Indexed: 04/29/2023] Open
Abstract
Background A third-generation coronary drug-eluting resorbable magnesium scaffold (DREAMS 3G) was developed to enhance the performance of previous scaffold generations and achieve angiographic outcomes comparable to those of contemporary drug-eluting stents. Methods This prospective, multicenter, non-randomized, first-in-human study was conducted at 14 centers in Europe. Eligible patients had stable or unstable angina, documented silent ischemia, or non-ST-elevation myocardial infarction, and a maximum of two single de novo lesions in two separate coronary arteries with a reference vessel diameter between 2.5 mm and 4.2 mm. Clinical follow-up was scheduled at one, six and 12 months and annually thereafter until five years. Invasive imaging assessments were scheduled six and 12 months postoperatively. The primary endpoint was angiographic in-scaffold late lumen loss at six months. This trial was registered at ClinicalTrials.gov (NCT04157153). Findings Between April 2020 and February 2022, 116 patients with 117 coronary artery lesions were enrolled. At six months, in-scaffold late lumen loss was 0.21 mm (SD 0.31). Intravascular ultrasound assessment showed preservation of the scaffold area (mean 7.59 mm2 [SD 2.21] post-procedure vs 6.96 mm2 [SD 2.48]) at six months) with a low mean neointimal area (0.02 mm2 [SD 0.10]). Optical coherence tomography revealed that struts were embedded in the vessel wall and were already hardly discernible at six months. Target lesion failure occurred in one (0.9%) patient; a clinically driven target lesion revascularization was performed on post-procedure day 166. No definite or probable scaffold thrombosis or myocardial infarction was observed. Interpretation These findings show that the implantation of DREAMS 3G in de novo coronary lesions is associated with favorable safety and performance outcomes, comparable to contemporary drug-eluting stents. Funding This study was funded by BIOTRONIK AG.

Impact of technique on bifurcation stent outcomes in the European Bifurcation Club Left Main Coronary Trial. Catheter Cardiovasc Interv 2023; 101:553-562.

Abstract
BACKGROUND Techniques for provisional and dual-stent left main bifurcation stenting require optimization. AIM To identify technical variables influencing procedural outcomes and periprocedural myocardial infarction following left main bifurcation intervention. METHODS Procedural and outcome data were analyzed in 438 patients from the per-protocol cohort of the European Bifurcation Club Left Main Trial (EBC MAIN). These patients were randomized to the provisional strategy or a compatible dual-stent extension (T, T-and-protrude, or culotte). RESULTS Mean age was 71 years and 37.4% presented with an acute coronary syndrome. Transient reduction of side vessel thrombolysis in myocardial infarction flow occurred after initial stent placement in 5% of procedures but was not associated with periprocedural myocardial infarction. Failure to rewire a jailed vessel during any strategy was more common when jailed wires were not used (9.5% vs. 2.5%, odds ratio [OR]: 6.4, p = 0.002). In the provisional cohort, the use of the proximal optimization technique was associated with less subsequent side vessel intervention (23.3% vs. 41.9%, OR: 0.4, p = 0.048). Side vessel stenting was predominantly required for dissection, which occurred more often following side vessel preparation (15.3% vs. 4.4%, OR: 3.1, p = 0.040). Exclusive use of noncompliant balloons for kissing balloon inflation was associated with reduced need for side vessel intervention in provisional cases (20.5% vs. 38.5%, OR: 0.4, p = 0.013), and a reduced risk of periprocedural myocardial infarction across all strategies (2.9% vs. 7.7%, OR: 0.2, p = 0.020). CONCLUSION When performing provisional or compatible dual-stent left main bifurcation intervention, jailed wire use is associated with successful jailed vessel rewiring. Side vessel preparation in provisional patients is linked to increased side vessel dissection requiring stenting. Use of the proximal optimization technique may reduce the need for additional side vessel intervention, and noncompliant balloon use for kissing balloon inflation is associated with a reduction in both side vessel stenting and periprocedural myocardial infarction.

Abstract
BACKGROUND Improvements in drug-eluting stent design have led to a reduced frequency of repeat revascularisation and new biodegradable polymer coatings may allow a shorter duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). AIMS The Improved Drug-Eluting stent for All-comers Left Main (IDEAL-LM) study aims to investigate long-term clinical outcomes after implantation of a biodegradable polymer platinum-chromium everolimus-eluting stent (BP-PtCr-EES) followed by 4 months DAPT compared to a durable polymer cobalt-chromium everolimus-eluting stent (DP-CoCr-EES) followed by 12 months DAPT in patients undergoing PCI of unprotected left main coronary artery (LMCA) disease. METHODS This is a multicentre randomised clinical trial study in patients with an indication for coronary artery revascularisation who have been accepted for PCI for LMCA disease after Heart Team consultation. Patients were randomly assigned in a 1:1 ratio to receive either the BP-PtCr-EES or the DP-CoCr-EES. The primary endpoint was a non-inferiority comparison of the rate of major adverse cardiovascular events (MACE), defined as all-cause death, myocardial infarction, or ischaemia-driven target vessel revascularisation at 2 years. RESULTS Between December 2014 and October 2016, 818 patients (410 BP-PtCr-EES and 408 DP-CoCr-EES) were enrolled at 29 centres in Europe. At 2 years, the primary endpoint of MACE occurred in 59 patients (14.6%) in the BP-PtCr-EES group and 45 patients (11.4%) in the DP-CoCr-EES group; 1-sided upper 95% confidence interval (CI) 7.18%; p=0.04 for non-inferiority; p=0.17 for superiority. The secondary endpoint event of BARC 3 or 5 bleeding occurred in 11 patients (2.7%) in the BP-PtCr-EES group and 2 patients (0.5%) in the DP-CoCr-EES group (p=0.02). CONCLUSIONS In patients undergoing PCI of LMCA disease, after two years of follow-up, the use of a BP-PtCr-EES with 4 months of DAPT was non-inferior to a DP-CoCr-EES with 12 months of DAPT with respect to the composite endpoint of all-cause death, myocardial infarction or ischaemia-driven target vessel revascularisation.

Abstract
OBJECTIVES to test the safety and efficacy of intravascular imaging and specifically optical coherence tomography (OCT) as a diagnostic tool for left main angioplasty and analyze the mid-term outcome accordingly. BACKGROUND Clinical data and international guidelines recommend the use of intravascular imaging ultrasound (IVUS) to guide left main (LM) angioplasty. Despite early experience using OCT in this setting is encouraging, the evidence supporting its use is still limited. METHODS ROCK II is a multicenter, investigator-driven, retrospective European study to compare the performance of IVUS and OCT versus angiography in patients undergoing distal-LM stenting. The primary study endpoint was target-lesion failure (TLF) including cardiac death, target-vessel myocardial infarction and target-lesion revascularization. We designed this study hypothesizing the superiority of intravascular imaging over angiographic guidance alone, and the non-inferiority of OCT versus IVUS. RESULTS A total of 730 patients, 377 with intravascular-imaging guidance (162 OCT, 215 IVUS) and 353 with angiographic guidance, were analyzed. The one-year rate of TLF was 21.2% with angiography and 12.7% with intravascular-imaging (p = 0.039), with no difference between OCT and IVUS (p = 0.26). Intravascular-imaging was predictor of freedom from TLF (HR 0.46; 95% CI 0.23-0.93: p = 0.03). Propensity-score matching identified three groups of 100 patients each with no significant differences in baseline characteristics. The one-year rate of TLF was 16% in the angiographic, 7% in the OCT and 6% in the IVUS group, respectively (p = 0.03 for IVUS or OCT vs. angiography). No between-group significant differences in the rate of individual components of TLF were found. CONCLUSIONS Intravascular imaging was superior to angiography for distal LM stenting, with no difference between OCT and IVUS.

One-year performance of thin-strut cobalt chromium sirolimus-eluting stent versus thicker strut stainless steel biolimus-eluting coronary stent: a propensity-matched analysis of two international all-comers registries. Coron Artery Dis 2021; 32:391-396. [PMID: 33060529 PMCID: PMC8248251 DOI: 10.1097/mca.0000000000000958] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Accepted: 08/08/2020] [Indexed: 12/05/2022]
Abstract
OBJECTIVES Recent improvements in coronary stent design have focussed on thinner struts, different alloys and architecture, more biocompatible polymers, and shorter drug absorption times. This study evaluates safety and efficacy of a newer generation thin-strut cobalt chromium sirolimus-eluting coronary stent (SES, Ultimaster) in comparison with a second-generation thicker strut stainless steel biolimus-eluting stent (BES, Nobori) in percutaneous coronary intervention (PCI) practice. METHODS A propensity score analysis was performed to adjust for differences in baseline characteristics of 8137 SES patients and 2738 BES patients of two PCI registries (e-Ultimaster and NOBORI 2). An independent clinical event committee adjudicated all endpoint-related adverse events. RESULTS The use of SES, as compared with BES was associated with a significantly lower rate of myocardial infarction (MI) (1.2% vs 2.2%; P = 0.0006) and target vessel-related MI (1.1% vs 1.8%; P = 0.002) at 1 year. One-year composite endpoints of all predefined endpoints were lower in patients undergoing SES implantation (target lesion failure: 3.2% vs 4.1%; P = 0.03, target vessel failure: 3.7% vs 5.0%; P = 0.003, patient-oriented composite endpoint 5.7% vs 6.8%; P = 0.03). No significant differences between SES and BES were observed in all-cause death (2.0% vs 1.6%; P = 0.19), cardiac death (1.2% vs 1.2%; P = 0.76) or stent thrombosis (0.6% vs 0.8%; P = 0.43). CONCLUSIONS These findings suggest an improved clinical safety and efficacy of a newer generation thin-strut SES as compared with a second-generation thicker strut BES.

BIOSOLVE-IV-registry: Safety and performance of the Magmaris scaffold: 12-month outcomes of the first cohort of 1,075 patients. Catheter Cardiovasc Interv 2021; 98:E1-E8. [PMID: 32881396 PMCID: PMC8359313 DOI: 10.1002/ccd.29260] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 05/07/2020] [Accepted: 08/22/2020] [Indexed: 12/03/2022]
Abstract
OBJECTIVES We aimed to assess the safety and performance of the Magmaris sirolimus-eluting bioresorbable magnesium scaffold in a large patient population. BACKGROUND Magmaris has shown good outcomes in small-sized controlled trials, but further data are needed to confirm its usability, safety, and performance. METHODS BIOSOLVE-IV is an international, single arm, multicenter registry including patients with a maximum of two single de novo lesions. Follow-up is scheduled up to 5 years; the primary outcome is target lesion failure (TLF) at 12 months. RESULTS A total of 1,075 patients with 1,121 lesions were enrolled. Mean patient age was 61.3 ± 10.5 years and 19.2% (n = 206) presented with non-ST-elevation myocardial infarction (NSTEMI). Lesions were 3.2 ± 0.3 mm in diameter and 14.9 ± 4.2 mm long; 5.1% (n = 57) were bifurcation lesions. Device success was 97.3% (n = 1,129) and procedure success 98.9% (n = 1,063). The Kaplan-Meier estimate of TLF at 12 months was 4.3% [95% confidence interval, CI: 3.2, 5.7] consisting of 3.9% target lesion revascularizations, 0.2% cardiac death, and 1.1% target-vessel myocardial infarction. Definite/probable scaffold thrombosis occurred in five patients (0.5% [95% CI: 0.2, 1.1]), thereof four after early discontinuation of antiplatelet/anticoagulation therapy. CONCLUSION BIOSOLVE-IV confirms the safety and performance of the Magmaris scaffold in a large population with excellent device and procedure success and a very good safety profile up to 12 months in a low-risk population.

Abstract
BACKGROUND Patients with non-left-main coronary bifurcation lesions are usually best treated with a stepwise provisional approach. However, patients with true left main stem bifurcation lesions have been shown in one dedicated randomized study to benefit from systematic dual stent implantation. METHODS AND RESULTS Four hundred and sixty-seven patients with true left main stem bifurcation lesions requiring intervention were recruited to the EBC MAIN study in 11 European countries. Patients were aged 71 ± 10 years; 77% were male. Patients were randomly allocated to a stepwise layered provisional strategy (n = 230) or a systematic dual stent approach (n = 237). The primary endpoint (a composite of death, myocardial infarction, and target lesion revascularization at 12 months) occurred in 14.7% of the stepwise provisional group vs. 17.7% of the systematic dual stent group (hazard ratio 0.8, 95% confidence interval 0.5-1.3; P = 0.34). Secondary endpoints were death (3.0% vs. 4.2%, P = 0.48), myocardial infarction (10.0% vs. 10.1%, P = 0.91), target lesion revascularization (6.1% vs. 9.3%, P = 0.16), and stent thrombosis (1.7% vs. 1.3%, P = 0.90), respectively. Procedure time, X-ray dose and consumables favoured the stepwise provisional approach. Symptomatic improvement was excellent and equal in each group. CONCLUSIONS Among patients with true bifurcation left main stem stenosis requiring intervention, fewer major adverse cardiac events occurred with a stepwise layered provisional approach than with planned dual stenting, although the difference was not statistically significant. The stepwise provisional strategy should remain the default for distal left main stem bifurcation intervention. STUDY REGISTRATION http://clinicaltrials.gov NCT02497014.

Abstract
BACKGROUND Polymer-free drug-coated stents provide superior clinical outcomes to bare-metal stents in patients at high bleeding risk who undergo percutaneous coronary intervention (PCI) and are treated with 1 month of dual antiplatelet therapy. Data on the use of polymer-based drug-eluting stents, as compared with polymer-free drug-coated stents, in such patients are limited. METHODS In an international, randomized, single-blind trial, we compared polymer-based zotarolimus-eluting stents with polymer-free umirolimus-coated stents in patients at high bleeding risk. After PCI, patients were treated with 1 month of dual antiplatelet therapy, followed by single antiplatelet therapy. The primary outcome was a safety composite of death from cardiac causes, myocardial infarction, or stent thrombosis at 1 year. The principal secondary outcome was target-lesion failure, an effectiveness composite of death from cardiac causes, target-vessel myocardial infarction, or clinically indicated target-lesion revascularization. Both outcomes were powered for noninferiority. RESULTS A total of 1996 patients at high bleeding risk were randomly assigned in a 1:1 ratio to receive zotarolimus-eluting stents (1003 patients) or polymer-free drug-coated stents (993 patients). At 1 year, the primary outcome was observed in 169 of 988 patients (17.1%) in the zotarolimus-eluting stent group and in 164 of 969 (16.9%) in the polymer-free drug-coated stent group (risk difference, 0.2 percentage points; upper boundary of the one-sided 97.5% confidence interval [CI], 3.5; noninferiority margin, 4.1; P = 0.01 for noninferiority). The principal secondary outcome was observed in 174 patients (17.6%) in the zotarolimus-eluting stent group and in 169 (17.4%) in the polymer-free drug-coated stent group (risk difference, 0.2 percentage points; upper boundary of the one-sided 97.5% CI, 3.5; noninferiority margin, 4.4; P = 0.007 for noninferiority). CONCLUSIONS Among patients at high bleeding risk who received 1 month of dual antiplatelet therapy after PCI, use of polymer-based zotarolimus-eluting stents was noninferior to use of polymer-free drug-coated stents with regard to safety and effectiveness composite outcomes.

Abstract
Abstract
Background
Compare-Acute trial showed a 1-year superior outcome of FFR-guided acute complete revascularization (FFR-CR) compared to culprit-lesion-only revascularization (CLO) in patients presenting with ST-segment elevation myocardial infarction (STEMI) and multi-vessel disease (MVD). Long-term results and financial impact of this strategy are unknown.
Purpose
To evaluate if FFR-CR strategy is superior to CLO strategy in terms of health care costs at 3 year follow-up.
Methods
Compare-Acute is a multicenter, investigator-initiated prospective randomized controlled trial that involved 24 sites. Patients with STEMI and MVD were randomized 1:2 after successful primary PCI, towards FFR-CR or CLO treatment strategies (295 vs 590 pts). All stenosis ≥50% by angiography in the non-infarct artery were investigated by FFR in both arms. In the FFR-CR arm, all non-culprit (NC) lesions with a FFR ≤0.80 were treated by PCI. In the CLO arm pts underwent blinded FFR procedure of the NC lesions. Further treatment of these lesions was based on symptoms and/or ischemia testing during follow-up with an allowed treatment window of 45 days. The primary endpoint was defined as a composite of all-cause mortality, non-fatal myocardial infarction, any revascularization and cerebrovascular events (MACCE) at 12 months. The major secondary endpoints are MACCE and health care costs from both strategies up to 3-year follow-up. Cost-analysis is done from an insurance/governmental perspective in countries that use Diagnosis Related Group (DRG) costs: the Netherlands, Germany, Sweden and Poland.
Results
1-year results have already been published and showed superior outcome of patients in the FFR-CR arm. According to the Dutch system, at 1 year of follow-up the average cost per patient was 8.150€ in the FFR-CR arm, and 10.319€ in the CLO arm (−21%). The better cost-effectiveness of FFR-CR strategy remained at 3 years of follow-up: average cost per patient was 8.653€ in the FFR-CR arm and 11.100€ in the CLO arm (−22%). Same 3-year data was confirmed using DRG analysis according to the German system (FFR-CR 4.887€ vs CLO 5.200€; −6.0%) and the Swedish system (FFR-CR 6.205€ vs CLO 8.133€; −23.7%). FFR-CR strategy was not more costly according to the Polish system (FFR-CR 3.704€ vs CLO 3.685€; +0.5%). Moreover, the better outcome of the FFR-CR group was mantained at 3 year follow-up (data not shown).
Figure 1
Conclusion
Our cost-analysis of the Compare Acute Trial shows that the strategy of FFR-guided complete revascularization in patients with STEMI and MVD is not only superior in terms of outcome, but also in terms of health care costs at 1 year. This benefit is maintained at 3 years follow-up.

Abstract
Background
Compare-Acute trial showed a 1-year superior outcome of FFR-guided acute complete revascularization (FFR-CR) compared to culprit-lesion-only revascularization (CLO) in patients presenting with ST-segment elevation myocardial infarction (STEMI) and multi-vessel disease (MVD). Long-term outcome results are unknown.
Purpose
To evaluate if FFR-CR strategy is superior to CLO strategy in terms of outcome at 3 year follow-up.
Methods
Compare-Acute is a multicenter, investigator-initiated prospective randomized controlled trial that involved 24 sites. Patients with STEMI and MVD were randomized, after successful primary PCI towards FFR-CR or CLO treatment strategies with a 1:2 ratio (295 pts vs 590 pts). All stenosis ≥50% in the non-infarct artery were investigated by FFR in both arms. In the FFR-CR arm, all non-culprit (NC) lesions with a FFR ≤0.80 were treated by PCI. In the CLO arm pts underwent blinded FFR procedure of the NC lesions. Further treatment of these lesions was based on symptoms and/or ischemia testing during follow-up with an allowed treatment window of 45 days. The primary endpoint was defined as a composite of all-cause mortality, non-fatal myocardial infarction, any revascularization and cerebrovascular events (MACCE) at 12 months. The major secondary endpoint is MACCE from both strategies up to 3-year follow-up.
Results
1-year clinical outcomes have already been presented and published. At 36 months the composite end-point of MACCE occurred in 46 patients in the FFR-CR group vs 178 patients in the CLO group (15.6% vs 30.2%; HR 0.46, 95% CI 0.29–0.59; p<0.01), as shown in Fig. 1. The incidence of death (4 pts vs 10 pts; 1.4% vs 1.7%; HR 0.86, 95% CI 0.39–1.8; p=0.71), MI (20 pts vs 53 pts; 7.1% vs 9.3%; HR 0.74, 95% CI 0.44–1.24; p=0.25) and stroke (1 pt vs 7 pts; 0.3% vs 1.2%; HR 0.29, 95% CI 0.03–2.3; p=0.24) was not significantly different in the two groups, but revascularizations were significantly higher in the CLO group: 37 patients in the FFR-CR group vs 149 patients in the CLO group (13.0% vs 26.0%; HR 0.45; 95% CI 0.31–0.64; p<0.01). Furthermore, in a subgroup analysis, when we considered only patients with FFR positive non-culprit lesions in both arms, we found a higher incidence of MI at follow-up in the CLO arm compared to the FFR-CR arm: 30/224 vs 13/194 (13.4% vs 6.7%; p 0.03).
MACCE-free survival at 3 years
Conclusion
With this analysis of the Compare-Acute trial we confirm that the benefit of a FFR-guided complete revascularization strategy in patients with STEMI and MVD is maintained at 3 years of follow-up. This difference is mainly driven by increased revascularizations in the CLO arm, but also by increased incidence of MI in the CLO subgroup with FFR+ lesions that were left untreated.

Abstract
BACKGROUND The Magmaris bioresorbable magnesium scaffold was successfully tested in in-vitro and in clinical premarket studies. Subsequently the Magmaris postmarket program aimed to review intraprocedural data of at least 2000 patients to assess user preferences, guideline adherence and intraprocedural performance in clinical routine. METHODS This international multicentre survey encompasses data from 356 hospitals across 45 countries. As part of the certification for Magmaris implantation, each hospital had to complete consecutive post-market evaluation forms of their first 10 commercial Magmaris patients. RESULTS From June 2016 to May 2018, data on 2018 implantations were collected. Main reasons for selecting Magmaris was patients' life expectancy (67%, n = 1359) and low or not calcified lesions, (67%, n = 1357). Magmaris was successfully deployed in 99% of cases (n = 1995), predilatation was performed in 95% (n = 1922) and post-dilatation in 87% (n = 1756). Physicians rated the overall performance and the pushability as good or very good in 96% of cases (n = 1799). Guide wire friction, trackability, and conformability were rated as good or very good in 94% of cases, and crossability in 93%. The majority of patients were scheduled to receive dual antiplatelet therapy for up to 12 months. CONCLUSION Generally, implantation guidelines were adhered to and theoretical advantages of the metal scaffold observed in in-vitro tests have translated into practice with good intraprocedural performance outcomes, confirming the controlled roll-out of this novel technology into clinical practice. SUMMARY FOR ANNOTATED TABLE OF CONTENT The Magmaris 2000 program includes the first commercial cases at each hospital. Overall, data on 2018 implantations were collected. The high rate of pre- and post-dilatation as well as other parameters confirm that generally the implantation guidelines are adhered to and the good intraprocedural performance (rated as good or very good in 96%) confirm the theoretical advantages of a metallic scaffold in practice.

Abstract
OBJECTIVES The Magmaris-ACS Registry is the first assessment of the Magmaris implantation in the acute coronary syndrome (ACS) population. BACKGROUND Bioresorbable vascular scaffolds (BRS), the newest coronary stent technology, was developed to overcome the limitations of the metallic drug-eluting stents (DES). Current promising data of the Magmaris in patients with stable angina have encouraged to validate the second generation BRS in ACS indications. METHODS The study population consisted of the consecutive patients who underwent PCI with the Magmaris BRS in the settings of ACS. Patients with ST-segment elevation myocardial infarction were excluded from enrolment. Baseline demographic and angiographic characteristics, as well as 30-day and 6-month clinical, follow up were prospectively analyzed. RESULTS Fifty patients were enrolled at mean age 62.9 ± 8.4 years (unstable angina-52% and non-ST-segment myocardial infarction [NSTEMI]-48%). Treated fifty-one de novo lesions were located in LAD (37%), LCx (14%), and RCA (49%), respectively. Angiographic success in the target lesion was 100%. One case of recurrent ischemia was observed a day after the index procedure, due to the significant distal edge dissection a regular metallic DES overlapping Magmaris was implanted. No other in-hospital events occurred (procedural success 98%). Six-Month follow up showed none device-oriented endpoints such as cardiac mortality, target vessel myocardial infarction or target vessel revascularization. None early scaffold thrombosis was reported. CONCLUSION The use of the Magmaris BRS in non-ST elevation ACS patient is associated with a procedural safety and promising early angiographic and clinical outcomes. Long-term follow-up and further evaluation in large prospective randomized controlled trials are needed.

Abstract
BACKGROUND In patients with ST-segment elevation myocardial infarction (STEMI), the use of percutaneous coronary intervention (PCI) to restore blood flow in an infarct-related coronary artery improves outcomes. The use of PCI in non-infarct-related coronary arteries remains controversial. METHODS We randomly assigned 885 patients with STEMI and multivessel disease who had undergone primary PCI of an infarct-related coronary artery in a 1:2 ratio to undergo complete revascularization of non-infarct-related coronary arteries guided by fractional flow reserve (FFR) (295 patients) or to undergo no revascularization of non-infarct-related coronary arteries (590 patients). The FFR procedure was performed in both groups, but in the latter group, both the patients and their cardiologist were unaware of the findings on FFR. The primary end point was a composite of death from any cause, nonfatal myocardial infarction, revascularization, and cerebrovascular events at 12 months. Clinically indicated elective revascularizations performed within 45 days after primary PCI were not counted as events in the group receiving PCI for an infarct-related coronary artery only. RESULTS The primary outcome occurred in 23 patients in the complete-revascularization group and in 121 patients in the infarct-artery-only group that did not receive complete revascularization, a finding that translates to 8 and 21 events per 100 patients, respectively (hazard ratio, 0.35; 95% confidence interval [CI], 0.22 to 0.55; P<0.001). Death occurred in 4 patients in the complete-revascularization group and in 10 patients in the infarct-artery-only group (1.4% vs. 1.7%) (hazard ratio, 0.80; 95% CI, 0.25 to 2.56), myocardial infarction in 7 and 28 patients, respectively (2.4% vs. 4.7%) (hazard ratio, 0.50; 95% CI, 0.22 to 1.13), revascularization in 18 and 103 patients (6.1% vs. 17.5%) (hazard ratio, 0.32; 95% CI, 0.20 to 0.54), and cerebrovascular events in 0 and 4 patients (0 vs. 0.7%). An FFR-related serious adverse event occurred in 2 patients (both in the group receiving infarct-related treatment only). CONCLUSIONS In patients with STEMI and multivessel disease who underwent primary PCI of an infarct-related artery, the addition of FFR-guided complete revascularization of non-infarct-related arteries in the acute setting resulted in a risk of a composite cardiovascular outcome that was lower than the risk among those who were treated for the infarct-related artery only. This finding was mainly supported by a reduction in subsequent revascularizations. (Funded by Maasstad Cardiovascular Research and others; Compare-Acute ClinicalTrials.gov number, NCT01399736 .).
