Background: The Myval balloon-expandable (BE) valve has shown encouraging early clinical data in terms of safety and efficacy. Comparative data with other well-established contemporary valves are nonetheless still scarce. This study aims to compare the performance of the Myval BE valve with the Evolut self-expanding (SE) valve. Methods: In this retrospective single-center study, 223 patients with symptomatic severe aortic stenosis (AS) were included and treated with the Myval BE valve (n = 120) or with the Evolut SE valve (n = 103). Then, 91 pairs were compared after matching. Clinical outcomes were evaluated at 30 days and 1 year. Echocardiographic follow-up was performed at 30 days. Results: Procedural complications were rare in both groups. At the 30-day follow-up, no significant difference in cardiac death (Myval: 1% vs. Evolut: 2%, p = 0.56), stroke (2% vs. 4%, p = 0.41) and myocardial infarction (1% vs. 3%, p = 0.31) was observed. A permanent pacemaker implantation (PPI) was significantly less needed in the Myval group (4% vs. 15%, p = 0.01). At 1 year, cardiac death (2% vs. 4%, p = 0.41) and the stroke rate (7% vs. 5%, p = 0.76) were similar. Moderate–severe paravalvular leakage (PVL) was also comparable in both groups (1% vs. 4%, p = 0.17). Conclusion: Safety and efficacy outcomes were comparable between the two valves, except for a higher PPI rate for the Evolut SE valve. Up to 1-year follow-up, clinical outcomes showed acceptable rates of stroke and cardiac death with both valves. Valve hemodynamics were excellent with a low rate of moderate–severe PVL in both groups.

Several studies have compared surface electrocardiographic changes following different self-expandable (SE) (Evolut (Medtronic, USA); Acurate (Boston Scientific, USA); Portico (Abbott, USA); and Allegra (NVT, Germany)) and balloon-expandable (BE) Sapien-3 (Edwards Lifesciences, USA) transcatheter heart valves. We aimed to compare these prosthesis with the novel Myval BE prosthesis (Meril Life, India).Academic European registry of consecutive patients with severe aortic stenosis who received any of the 6 aforementioned valves. Baseline, post-procedural, and discharge 12‑leads electrocardiograms (ECG) were centrally analyzed and compared.A total of 1131 patients were included: 135 Myval (11.9%), 290 Sapien-3 (25.6%), 298 Evolut (26.3%), 180 Acurate (15.9%), 125 Portico (11.1%), and 103 Allegra (9.1%). There were no baseline differences in intraventricular conduction disturbances rate. Compared to the novel BE Myval, there were similar procedural and in-hospital outcomes. Similar rates of early new permanent pacemaker implant (PPI) were observed amongst Myval (7.4%), Sapien-3 (13.4%), and Acurate (9.1%), but Evolut, Portico, and Allegra presented significantly higher rates (18.5%, p = 0.003; 29.5% p0.001 and 22%, p = 0.001, respectively). Central analysis of ECGs, unraveled significant prolongation of the PR segment with Evolut, Portico and Allegra whereas Evolut, Acurate, and Portico showed significant QRS widening compared to Myval. However, at discharge no differences in PR segment duration were observed while, Evolut, and Portico- but not Acurate, Allegra or Sapien-3 - still presented significant widening of QRS segment compared to Myval.After blinded central ECG analysis, the novel Myval balloon-expandable prosthesis was associated with a low rate of early conduction disturbances.

ObjectivesThe balloon-expandable Sapien-3 valve demonstrated superior results in terms of residual aortic regurgitation when compared with self-expandable devices. We aimed to compare for the first-time early outcomes of Sapien-3 transcatheter heart valve (THV) with the balloon-expandable Myval device.MethodsConsecutive real-world patients from nine European institutions with symptomatic severe aortic stenosis treated either with Sapien-3 or Myval THV devices after June 2018 were compared. Early clinical outcomes were prospectively gathered and blinded analysis of 30-day echocardiography was conducted. Matching for the following variables was performed: age, body surface area, Society of Thoracic Surgeons risk score, left ventricular function, mean gradient, transfemoral approach, aortic valvular calcium, aortic annulus mean diameter, area and eccentricity index.ResultsA total of 416 patients treated either with the Sapien-3 (n=286, 68.7%) or with Myval THV (n=130, 31.3%) were included and 103 pairs compared after matching. Baseline characteristics were similar. Procedural success rate (Sapien-3: 94.2%; Myval: 93.2%, p=0.219), 30-day mortality (Sapien-3: 2.9%; Myval: 0.97%, p=0.625), clinical efficacy (12.6 vs 4.9%, p=0.057) and early safety (12.6 vs 4.9%, p=0.096) were comparable. There was a lower need for new permanent pacemaker (15.5 vs 5.8% p=0.020) with Myval. No significant differences were found in terms of ≥moderate aortic regurgitation (1% for Sapien-3, 0% for Myval, p=0.314), but mean gradients were higher following Sapien-3 than after Myval (pConclusionsThe new Myval balloon-expandable THV was favourable in terms of safety, with low rate of permanent pacemaker and with favourable residual gradients and paravalvular leak rate according to blinded echocardiographic analysis.

Randomized controlled trials for in-stent restenosis (ISR) and de novo lesions in small-diameter vessels have shown promising results, but data on DCB use in real-world practice are still scarce. The aim of the PEARL (Paclitaxel-Eluting Angioplasty Balloon in the Real-World) registry was to evaluate the safety and efficacy of a paclitaxel DCB in real-world percutaneous coronary intervention (PCI) practice.Between 2014 and 2019, a total of 513 patients treated with the Protégé paclitaxel DCB (Wellinq) were prospectively included at 4 hospitals in the Netherlands. The primary endpoint was 2-year major adverse cardiac event (MACE), defined as cardiac death, target-vessel myocardial infarction, or target-lesion revascularization (TLR).DCB was used for ISR in 382 patients and for de novo lesions in 131 patients. Acute coronary syndrome was the reason for presentation in 58.9% of patients. At lesion level, 34.1% of lesions were classified as type B2 and 36.1% as type C. Predilation was performed in 62.2% and noncompliant DCB was used in 40.7% of lesions. DCB-related procedural complications were infrequent (3.3%, mostly coronary dissection [2.3%]). Bailout stenting was required in 3.1%. MACE during 2-year follow-up occurred in 17.1% of patients treated for ISR and 9.7% of patients treated for de novo lesions. The incidence of TLR was 11.7% of ISR patients and 2.9% of de novo patients. History of coronary artery bypass grafting and lesion length were predictors of MACE in patients treated for ISR.The use of Protégé paclitaxel DCB for PCI of ISR and de novo lesions is safe and effective during 2-year follow-up.

Purpose: The COMBO biodegradable polymer sirolimus-eluting stent includes endothelial progenitor cell capture (EPC) technology for rapid endothelialization, which may offer advantage in acute coronary syndromes (ACS). We sought to analyze the performance of the COMBO stent by ACS status and ACS subtype. Methods: The COMBO collaboration (n = 3614) is a patient-level pooled dataset from the MASCOT and REMEDEE registries. We evaluated outcomes by ACS status, and ACS subtype in patients with ST segment elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI) versus unstable angina (UA). The primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization. Secondary outcomes included stent thrombosis (ST). Results: We compared 1965 (54%) ACS and 1649 (46.0%) non-ACS patients. ACS presentations included 40% (n = 789) STEMI, 31% (n = 600) NSTEMI, and 29% (n = 576) UA patients. Risk of 1-year TLF was greater in ACS patients (4.5% vs. 3.3%, HR 1.51 95% CI 1.01–2.25, p = 0.045) without significant differences in definite/probable ST (1.1% vs 0.5%, HR 2.40, 95% CI 0.91–6.31, p = 0.08). One-year TLF was similar in STEMI, NSTEMI, and UA (4.8% vs 4.8% vs. 3.7%, p = 0.60), but definite/probable ST was higher in STEMI patients (1.9% vs 0.5% vs 0.7%, p = 0.03). Adjusted outcomes were not different in MI versus UA patients. Conclusions: Despite the novel EPC capture technology, COMBO stent PCI was associated with somewhat greater risk of 1-year TLF in ACS than in non-ACS patients, without significant differences in stent thrombosis. No differences were observed in 1-year TLF among ACS subtypes.

Objectives This final report from the REMEDEE Registry assessed the long‐term safety and efficacy of the dual‐therapy COMBO stent in a large unselected patient population. Background The bio‐engineered COMBO stent (OrbusNeich Medical BV, The Netherlands) is a dual‐therapy pro‐healing stent. Data of long‐term safety and efficacy of the this stent is lacking. Methods The prospective, multicenter, investigator‐initiated REMEDEE Registry evaluated clinical outcomes after COMBO stent implantation in daily clinical practice. One thousand patients were enrolled between June 2013 and March 2014. Results Five‐year follow‐up data were obtained in 97.2% of patients. At 5‐years, target lesion failure (TLF) (composite of cardiac death, target‐vessel myocardial infarction, or target lesion revascularization) was present in 145 patients (14.8%). Definite or probable stent thrombosis (ST) occurred in 0.9%, with no additional case beyond 3‐years of follow‐up. In males, 5‐year TLF‐rate was 15.6 versus 12.6% in females (p = .22). Patients without diabetes mellitus (DM) had TLF‐rate of 11.4%, noninsulin‐treated DM 22.7% (p = .001) and insulin‐treated DM 41.2% (p < .001). Patients presenting with non‐ST segment elevation acute coronary syndrome (NSTE‐ACS) had higher incidence of TLF compared to non‐ACS (20.4 vs. 13.3%; p = .008), while incidence with STE‐ACS was comparable to non‐ACS (10.7 vs. 13.3%; p = .43). Conclusion Percutaneous coronary intervention with the dual‐therapy COMBO stent in unselected patient population shows low rates of TLF and ST to 5 years. Remarkably, no case of ST was noted beyond 3 years.

Percutaneous coronary interventions in saphenous vein grafts can pose a variety of challenges, such as severely calcified lesions. If these lesions are nondilatable, lithotripsy can arguably be a proper tool for lesion preparation. We present a case in which a nondilatable, calcified saphenous vein graft was successfully treated using Shockwave lithotripsy. (Level of Difficulty: Intermediate.), Graphical abstract

Objectives The aim of this study was to evaluate 1-year clinical safety and efficacy of the dual-therapy COMBO stent in a large, all-comers patient-level pooled cohort. Background The COMBO stent (OrbusNeich Medical, Fort Lauderdale, Florida) is a novel stent with abluminal sirolimus elution from a biodegradable polymer and a luminal pro-healing anti-CD34+ antibody layer, which attracts circulating endothelial progenitor cells. These endothelial progenitor cells can quickly mature into normal endothelium, providing rapid endothelialization. Methods The MASCOT (Multinational Abluminal Sirolimus Coated biO-engineered stenT) (N = 2,614, 61 global sites) and REMEDEE (Randomized study to Evaluate the safety and effectiveness of an abluMinal sirolimus coatED bio-Engineered StEnt Post Market Registry) (N = 1,000, 9 European sites) registries are 2 prospective, multicenter studies evaluating clinical outcomes after attempted COMBO stent placement in all-comer patients undergoing percutaneous coronary intervention. In this patient-level pooled analysis we analyzed 1-year target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization. Furthermore, we determined predictors of 1-year TLF. Results A total of 3,614 patients (63.5 ± 11.2 years of age; 23.8% women) were included in this analysis. The prevalence of diabetes mellitus was 29.3%, and 54.3% patients presented with acute coronary syndrome. The primary endpoint of 1-year TLF occurred in 140 (3.9%) patients, with incidence of cardiac death in 1.6%, target vessel myocardial infarction in 1.2%, clinically driven target lesion revascularization in 2.2%, and definite stent thrombosis in 0.5% patients. Insulin-treated diabetes mellitus, chronic renal failure, and American College of Cardiology/American Heart Association lesion type B2/C were independent predictors of 1-year TLF. Conclusions In this large patient-level pooled analysis of patients treated with the dual-therapy COMBO stent excellent results at 1-year were observed.

Older patients who undergo coronary interventions are at greater risk of ischemic events and less likely to tolerate prolonged dual antiplatelet therapy (DAPT) due to bleeding risk. The COMBO biodegradable polymer sirolimus-eluting stent promotes rapid endothelialization through endothelial progenitor cell capture technology which may be advantageous in elderly patients. We compared 1-year clinical outcomes and DAPT cessation events in patients >75 versus ≤75 years from the MASCOT registry. MASCOT was a prospective, multicenter cohort study of all-comers undergoing attempted COMBO stenting. The primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, myocardial infarction (MI) not clearly attributed to a nontarget vessel or clinically driven target lesion revascularization. Bleeding was adjudicated using the Bleeding Academic Research Consortium criteria. Adjusted outcomes were analyzed using Cox regression methods. The study included 18% (n = 479) patients >75 years and 72% (n = 2,135) patients ≤75 years. One-year TLF occurred in 4.6% patients >75 years versus 3.1% patients ≤75years of age, p = 0.10; adj hazard ratio 1.36, 95% confidence intervals 0.77 to 2.38, p = 0.29. There were no significant differences in cardiac death (1.7% vs 1.3%, p = 0.55), MI (2.1% vs 1.2%, p = 0.14), target lesion revascularization (1.7% vs 1.4%, p = 0.60) and definite stent thrombosis (0.8% vs 0.4%, p = 0.19). Major Bleeding Academic Research Consortium 3,5 bleeding (3.1% vs 1.5%, p = 0.01) and DAPT cessation rates (32.4% vs 23.0%, p 75 years treated with COMBO stents had similar TLF but significantly greater incidence of bleeding than younger patients and DAPT cessation in one-third of patients over 1 year.

Background The COMBO drug-eluting stent combines sirolimus-elution from a biodegradable polymer with an anti-CD34+ antibody coating for early endothelialization. Objective We investigated for geographical differences in outcomes after percutaneous coronary intervention (PCI) with the COMBO stent among Asians and Europeans. Methods The COMBO Collaboration is a pooled patient-level analysis of the MASCOT and REMEDEE registries of all-comers undergoing attempted COMBO stent PCI. The primary outcome was 1-year target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction (TV-MI) and target lesion revascularization (TLR). Results This study included 604 Asians (17.9%) and 2775 Europeans (82.1%). Asians were younger and included fewer females, with a higher prevalence of diabetes mellitus but lower prevalence of other comorbidities than Europeans. Asians had a higher prevalence of ACC/AHA C type lesions and received longer stent lengths. More Asians than Europeans were discharged on clopidogrel (86.5% vs 62.8%) rather than potent P2Y12 inhibitors. One-year TLF occurred in 4.0% Asians and 4.1% of Europeans, p = 0.93. The incidence of cardiac death was higher in Asians (2.8% vs. 1.3%, p = 0.007) with similar rates of TV-MI (1.5% vs. 1.2%, p = 0.54) and definite stent thrombosis (0.3% vs. 0.5%, p = 0.84) and lower incidence of TLR than Europeans (1.0% vs. 2.5%, p = 0.025). After adjustment, differences for cardiac death and TLR were no longer significant. Conclusions In the COMBO collaboration, although 1-year TLF was similar regardless of geography, Asians experienced higher rates of cardiac death and lower TLR than Europeans, while incidence of TV-MI and ST was similar in both regions. Adjusted differences did not reach statistical significance. Clinicaltrial.gov identifier-numbers NCT01874002 (REMEDEE Registry), NCT02183454 (MASCOT registry).

Objectives The aim of this study was to report the 2-year results of the SURTAVI (Surgical Replacement and Transcatheter Aortic Valve Implantation) trial and confirm the interim Bayesian analysis. Background Transcatheter aortic valve replacement (TAVR) with a self-expanding valve was noninferior to surgery in patients with severe aortic stenosis and intermediate operative risk using Bayesian statistical methods. Novel Bayesian designs have been used to shorten the time to primary endpoint analysis in randomized clinical trials, although the predictive value of Bayesian analysis compared with frequentist approaches remains debated. Methods The SURTAVI trial randomized 1,660 patients. An interim analysis was performed 1 year after the 1,400th patient was treated to estimate the primary 2-year endpoint of all-cause mortality or disabling strokes for all patients. Results The Kaplan-Meier rate for the complete 2-year primary endpoint was 12.7% in the TAVR group and 12.6% in the surgery group (0.0% difference; 95% confidence interval: −3.4% to 3.5%), compared with 12.6% with TAVR and 14.0% with surgery (−1.4% difference; Bayesian credible interval: −5.2% to 2.3%) in the interim Bayesian analysis. A comparison of individual clinical, hemodynamic, and quality-of-life endpoints using Bayesian and frequentist methods found no significant differences. Conclusions The complete analysis of all patients with aortic stenosis at intermediate risk for surgery in the SURTAVI trial confirmed the noninferiority, with respect to the frequency of all-cause mortality or disabling stroke, of TAVR to surgery, as determined in the interim Bayesian analysis. Follow-up will extend out to 10 years.

BACKGROUND The COMBO drug eluting stent is a novel device with luminal endothelial progenitor cell capture technology for rapid homogeneous endothelialization. METHODS AND RESULTS We examined for sex differences in 1-year outcomes after COMBO stenting from the COMBO collaboration, a pooled patient-level dataset from the MASCOT and REMEDEE multicenter registries. The primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, target vessel-myocardial infarction (TV-MI), or clinically driven target lesion revascularization (CD-TLR). Secondary outcomes included stent thrombosis (ST). Adjusted outcomes were assessed using Cox regression methods. The study included 861 (23.8%) women and 2,753 (76.2%) men. Women were older with higher prevalence of several comorbidities including diabetes mellitus. Risk of 1-year TLF was similar in both sexes (3.8% vs. 3.9%, HR 0.92, 95% CI 0.59-1.42, p = .70), without sex differences in the incidence of cardiac death (1.6% vs. 1.5%, p = .78), TV-MI (1.5% vs. 1.1%, p = .32), or CD-TLR (2.0% vs. 2.2%, p = .67). Definite or probable ST occurred in 0.4% women and 1.0% men (HR 0.26, 95% CI 0.06-1.11, p = .069). CONCLUSIONS Despite greater clinical risks at baseline, women treated with COMBO stents had similarly low 1-year TLF and other ischemic outcomes compared to men.

Severely calcified coronary lesions remain a challenge in current percutaneous coronary interventions. Shockwave intravascular lithotripsy (Shockwave Medical, Inc., Santa Clara, California) is an alternative for rotational atherectomy in such lesions that supports stent deliverability and achieves optimal results. We describe a case of coronary artery perforation after use of this lithotripsy device.

Item does not contain fulltext BACKGROUND: The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) trial was a non-inferiority trial that compared percutaneous coronary intervention (PCI) using first-generation paclitaxel-eluting stents with coronary artery bypass grafting (CABG) in patients with de-novo three-vessel and left main coronary artery disease, and reported results up to 5 years. We now report 10-year all-cause death results. METHODS: The SYNTAX Extended Survival (SYNTAXES) study is an investigator-driven extension of follow-up of a multicentre, randomised controlled trial done in 85 hospitals across 18 North American and European countries. Patients with de-novo three-vessel and left main coronary artery disease were randomly assigned (1:1) to the PCI group or CABG group. Patients with a history of PCI or CABG, acute myocardial infarction, or an indication for concomitant cardiac surgery were excluded. The primary endpoint of the SYNTAXES study was 10-year all-cause death, which was assessed according to the intention-to-treat principle. Prespecified subgroup analyses were performed according to the presence or absence of left main coronary artery disease and diabetes, and according to coronary complexity defined by core laboratory SYNTAX score tertiles. This study is registered with ClinicalTrials.gov, NCT03417050. FINDINGS: From March, 2005, to April, 2007, 1800 patients were randomly assigned to the PCI (n=903) or CABG (n=897) group. Vital status information at 10 years was complete for 841 (93%) patients in the PCI group and 848 (95%) patients in the CABG group. At 10 years, 244 (27%) patients had died after PCI and 211 (24%) after CABG (hazard ratio 1.17 [95% CI 0.97-1.41], p=0.092). Among patients with three-vessel disease, 151 (28%) of 546 had died after PCI versus 113 (21%) of 549 after CABG (hazard ratio 1.41 [95% CI 1.10-1.80]), and among patients with left main coronary artery disease, 93 (26%) of 357 had died after PCI versus 98 (28%) of 348 after CABG (0.90 [0.68-1.20], pinteraction=0.019). There was no treatment-by-subgroup interaction with diabetes (pinteraction=0.66) and no linear trend across SYNTAX score tertiles (ptrend=0.30). INTERPRETATION: At 10 years, no significant difference existed in all-cause death between PCI using first-generation paclitaxel-eluting stents and CABG. However, CABG provided a significant survival benefit in patients with three-vessel disease, but not in patients with left main coronary artery disease. FUNDING: German Foundation of Heart Research (SYNTAXES study, 5-10-year follow-up) and Boston Scientific Corporation (SYNTAX study, 0-5-year follow-up).

Background: The bio-engineered COMBO stent (OrbusNeich Medical BV, The Netherlands) is a dual-therapy pro-healing stent. This novel technology may allow a shorter duration of dual antiplatelet therapy (DAPT) after stenting. We present the first 3 year clinical outcomes of patients treated with COMBO stent. Methods and results: The prospective, multicenter, investigator-initiated, all-comers REMEDEE Registry evaluates clinical outcomes after COMBO stent treatment. A 1,000 patients were enrolled between June 2013 and March 2014. Patients had a mean of 65 years ±11, 26% of the patients were females and 18% diabetics. More than 50% of patients presented with acute coronary syndrome, 60% of treated lesions were AHA/ACC lesion type B2 or C. Target lesion failure (TLF) at 3 year follow-up occurred in 10.7% of patients (N = 105). The separate components cardiac death, target vessel myocardial infarction and target lesion revascularization occurred in 4.1%, 2.0%, and 7.1%, respectively of patients. Definite stent thrombosis (ST) was observed in 0.7% of all patients. At 3-year follow-up there were only 73 patients taking DAPT. Conclusions: At 3-year follow-up, patients treated with COMBO stent in the present large prospective all-comers cohort, continue to show good clinical outcomes. Clinicaltrials.gov identifier: NCT01874002. Condensed abstract: The COMBO stent is a sirolimus-eluting stent with a luminal anti-CD34-antibody layer, that binds endothelial progenitor cells. These cells can differentiate to endothelial cells and stimulate early endothelialization of the stent. The REMEDEE Registry is the first large, multicenter, prospective, cohort study evaluating the clinical outcomes of 1,000 all-comers patients treated with COMBO stent. Target lesion failure at 3 year follow-up was 10.7% and the rate of definite ST was 0.7%.

Objectives: The aim of the present analysis is to compare the quantitative angiographic aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) among three balloon-expandable valves.Background: Quantitative videodensitometric aortography is an objective, accurate, and reproducible tool for adjudication of AR following TAVI.Methods: This is a retrospective corelab analysis, independent from industry, of aortograms from patients treated with TAVI using the balloon-expandable Myval transcatheter heart valve (THV) (Meril Life Sciences Pvt. Ltd., India), Sapien 3, and XT THVs (Edwards Lifesciences, Irvine, CA, USA). The study comprised of 108 analyzable aortograms from consecutive patients in a multicenter European registry who underwent Myval THV implantation. The results of quantitative assessment of AR in the Sapien 3 THV (n = 397) and Sapien XT THV (n = 239) were retrieved from a published pooled database.Results: The Myval THV had the lowest proportion of patients with moderate or severe angiographic quantitative AR (2.8%) compared to the Sapien 3 THV (8.3%; p = 0.049) and Sapien XT THV (10.9%; p = 0.012). Furthermore, the Myval THV had the lowest mean angiographic quantitative AR (6.3 ± 6.3%), followed by Sapien 3 THV (7.6 ± 7.1%) and Sapien XT THV (8.8 ± 7.5%), and it was significantly lower than that of the Sapien XT THV (p = 0.006), but not significantly different from Sapien 3 THV (p = 0.246).Conclusion: The Myval THV, in comparison with other BEV's analyzed in our database, showed a lower occurrence of moderate or severe AR after TAVI. These results should be confirmed in prospective cohorts of randomized patients with head-to-head THV comparisons.

OBJECTIVES We aimed to describe hemodynamic performance and clinical outcomes at 30-day follow-up of the balloon-expandable (BE) Myval transcatheter heart valve (THV) in low-risk patients. BACKGROUND The results of the next-generation BE Myval THV in low-risk aortic stenosis (AS) patients are still unknown. METHODS Retrospective registry performed in nine European centers including patients with low predicted operative mortality risk according to Society of thoracic surgeons (STS) and European system for cardiac operative risk evaluation (EuroSCORE-II) scores. RESULTS Between September 2019 and February 2021, a total of 100 patients (51% males, mean age 80 ± 6.5 years) were included. Mean STS score and EuroSCORE-II were 2.4 ± 0.8% and 2.2 ± 0.7%, respectively. Intermediate sizes were used in 39% (21.5 mm: 8%, 24.5 mm: 15%, 27.5 mm: 15%). There were no cases of valve embolization, coronary artery occlusion, annulus rupture, or procedural death. A definitive pacemaker implantation was needed in eight patients (8%). At 30-day follow-up aortic valve area (0.7 ± 0.2 vs. 2.1 ± 0.6 cm2 ) and mean aortic valve gradient (43.4 ± 11.1 vs. 9.0 ± 3.7 mmHg) improved significantly (p

Background: Not all patients with severe aortic valve stenosis are eligible for open-heart surgery or TAVR. CARDIAWAVE (Paris, France) has developed Valvosoft, a unique non-invasive ultrasound therapy device to treat aortic stenosis. The therapy aims to improve the opening of severely calcified aortic valves by cracking the calcium and reducing the stiffness in the aortic valve tissue by delivering transthoracically local shock waves on the valve leaflets. This study assesses the safety, feasibility and performance of this novel technique. Methods: This is a multi-center, prospective, first-in-man study designed to evaluate the safety and feasibility of the Valvosoft device. Ten patients with severe symptomatic calcific aortic stenosis and not eligible for SAVR/TAVR underwent a Valvosoft ultrasound therapy. Echocardiographic evaluation was performed by an independent core lab at baseline, discharge, and at 1, 3, 6 and 12 months along with clinical follow up. Results: Enrolled patients were advanced in age (84.1±6.5 yrs) with severe comorbidities (8 with heart failure, 5 with coronary heart disease and 5 with kidney failure). All had extensive aortic valve calcification with mean AVA of 0.61±0.17 cm2 and mean pressure gradient of 37.5±10.5 mmHg. At one-month follow-up, six patients had significantly improved their AVA with increase of 27.5% (p=0.03) and mean pressure gradient decrease of 23.2 % (p=0.025). These patients also received the highest dose and longest treatment duration. During one year follow up, 4 patients died due to progression of end stage heart failure not linked to the procedure and one patient had undergone a TAVR procedure. At 12 months, the five remaining patients has no device or procedure related major adverse events nor deterioration of neurological status. Echo, brain-MRI and clinical follow up will be presented. Conclusions: Non-invasive ultrasound therapy is feasible and safe in patients with severe aortic valve stenosis and can improve AVA and hemodynamic parameters. NIUT can be an important tool complementary to TAVI in treating patients with aortic valve stenosis.

The COMBO biodegradable polymer sirolimus-eluting stent includes endothelial progenitor cell capture (EPC) technology for rapid endothelialization, which may offer advantage in acute coronary syndromes (ACS). We sought to analyze the performance of the COMBO stent by ACS status and ACS subtype.The COMBO collaboration (n = 3614) is a patient-level pooled dataset from the MASCOT and REMEDEE registries. We evaluated outcomes by ACS status, and ACS subtype in patients with ST segment elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI) versus unstable angina (UA). The primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization. Secondary outcomes included stent thrombosis (ST).We compared 1965 (54%) ACS and 1649 (46.0%) non-ACS patients. ACS presentations included 40% (n = 789) STEMI, 31% (n = 600) NSTEMI, and 29% (n = 576) UA patients. Risk of 1-year TLF was greater in ACS patients (4.5% vs. 3.3%, HR 1.51 95% CI 1.01-2.25, p = 0.045) without significant differences in definite/probable ST (1.1% vs 0.5%, HR 2.40, 95% CI 0.91-6.31, p = 0.08). One-year TLF was similar in STEMI, NSTEMI, and UA (4.8% vs 4.8% vs. 3.7%, p = 0.60), but definite/probable ST was higher in STEMI patients (1.9% vs 0.5% vs 0.7%, p = 0.03). Adjusted outcomes were not different in MI versus UA patients.Despite the novel EPC capture technology, COMBO stent PCI was associated with somewhat greater risk of 1-year TLF in ACS than in non-ACS patients, without significant differences in stent thrombosis. No differences were observed in 1-year TLF among ACS subtypes.

In patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI), lack of ST-segment resolution (STR) is associated with poor prognosis at short- and long-term follow-up. The aim of this study was to evaluate the role of STR on very long-term outcomes in patients with STEMI treated with pPCI included in the EXAMINATION (Evaluation of the Xience-V Stent in Acute Myocardial Infarction) trial. Patients were stratified according to the presence of STR 50% and STR >= 70%, respectively. In both cases, this difference was mainly driven by a significant increase in the rate of all-cause death and any revascularization. After multivariable adjustment, STR < 70%, but not STR < 50%, resulted as a 5-year independent predictor of POCE (adjusted HR 1.338, 95% CI 1.008 to 1.778, p = 0.044). In conclusion, in patients with STEM!, the evaluation of 70% STR after pPCI provides independent prognostic information at 5-year follow-up and it can be used to identify patients at high risk of very long-term cardiovascular events.

Objectives This analysis investigates the 5-year outcomes of the biodegradable polymer biolimus-eluting stent (BP-BES) and durable polymer everolimus-eluting stent (DP-EES) in an all-comers population undergoing percutaneous coronary intervention. Background Recent 1- and 3-year results from randomized trials have indicated similar safety and efficacy outcomes of BP-BES and DP-EES. Whether benefits of the biodegradable polymer device arise over longer follow-up is unknown. Moreover, in-depth, prospective, long-term follow-up data on metallic drug-eluting stents with durable or biodegradable polymers are scarce. Methods The COMPARE II trial (Abluminal Biodegradable Polymer Biolimus-Eluting Stent Versus Durable Polymer Everolimus-Eluting Stent) was a prospective, randomized, multicenter, all-comers trial in which 2,707 patients were randomly allocated (2:1) to BP-BES or DP-EES. The pre-specified endpoint at 5 years was major adverse cardiac events, a composite of cardiac death, nonfatal myocardial infarction, or target vessel revascularization. Results Five-year follow-up was available in 2,657 patients (98%). At 5 years, major adverse cardiac events occurred in 310 patients (17.3%) in the BP-BES group and 142 patients (15.6%) in the DP-EES group (p = 0.26). The rate of the combined safety endpoint all-cause death or myocardial infarction was 15.0% in the BP-BES group versus 14.8% in the DP-EES group (p = 0.90), whereas the efficacy measure target vessel revascularization was 10.6% versus 9.0% (p = 0.18), respectively. Interestingly, definite stent thrombosis rates did not differ between groups (1.5% for BP-BES vs. 0.9% for DP-EES; p = 0.17). Conclusions The 5-year analysis comparing biodegradable polymer-coated BES and the durable polymer-coated EES confirms the initial early- and mid-term results regarding similar safety and efficacy outcomes in this all-comers percutaneous coronary intervention population.

Background Patients presenting with acute coronary syndrome (ACS) are at increased risk of complications after percutaneous coronary intervention with stent placement compared to patients with stable angina (SA) treated in an elective setting. The novel pro-healing COMBO stent is a bio-engineered drug eluting stent designed to promote vessel healing. Therefore, the stent may reduce this difference in clinical outcomes between elective and ACS-patients and prevent late stent thrombosis. Methods and Results The European, prospective, multicenter, 1000 all-comers patient REMEDEE registry evaluates clinical outcomes after COMBO stent placement in ACS- and elective patients. The primary endpoint at 12 months is target lesion failure (TLF), a composite of cardiac death, target-vessel myocardial infarction and target lesion revascularization. A total of 49.9% (n = 498) of patients presented with acute coronary syndrome. TLF was 7.1% in ACS patients, definite and probable stent thrombosis was observed in 0.5% of ACS patients and in all within 9 days post stenting. We found no significant difference in TLF between ACS and non-ACS patients and a low overall rate of TLF. Conclusions The COMBO stent is a safe and efficient device for patients presenting with ACS. Low ST rate and only early stent thrombosis were observed. © 2017 Wiley Periodicals, Inc.

Aims Our aim was to evaluate the long-term device performance and clinical outcomes of patients with symptomatic, severe aortic valve stenosis (AS) who underwent transcatheter aortic valve implantation (TAVI) with the CoreValve bioprosthesis. Methods and results The CoreValve CE Pivotal Study was a prospective, multicentre, single-arm TAVI trial using the CoreValve system. Valve performance, patient quality of life (QoL), New York Heart Association (NYHA) class, and mortality at four years were analysed in 126 patients (mean age 82.4 years, 42.9% male, mean logistic EuroSCORE 23.4%) with severe AS. Mean aortic valve gradient decreased from 46.9±16.1 mmHg at baseline to 9.8±4.1 mmHg at discharge and to 7.8±2.7 mmHg at four years. Mean effective orifice area increased from 0.7±0.2 cm2 to 1.8±0.4 cm2 after TAVI and was 1.6±0.5 cm2 at four years. There were no reports of structural valve deterioration or valve migration. There was sustained improvement in QoL and NYHA class in surviving patients. All-cause and cardiac survival was 45.3% and 62.6%, respectively, at four years. Conclusions The CoreValve bioprosthesis demonstrates long-term durability, stable haemodynamic function, and no evidence of structural deterioration. Most surviving patients continued to have improved NYHA class and QoL at four years.

Drug-eluting stents (DES) showed improved efficacy and safety compared with bare-metal stents (BMS), and international guidelines recommend their use as first line treatment. Yet, BMS are still widely used in practice, especially in large coronary vessels. We aimed to compare efficacy and safety of second-generation DES over BMS in large coronary culprit ST-segment elevated myocardial infarction lesions.We evaluated impact of large coronary stents (maximum size ≥3.50 mm) or smaller stents (3.50 mm), among 1498 patients with ST-segment elevated myocardial infarction undergoing primary percutaneous coronary intervention, randomly allocated to everolimus-eluting DES or to an equivalent BMS platform in the EXAMINATION trial (Clinical Evaluation of the Xience-V Stent in Acute Myocardial Infarction Trial). Clinical events up to 5 years of follow-up were evaluated.Large coronary stents were used in 683 patients (45.9%). At 5-year follow-up, the crude rate of the primary end point, a composite of all-cause death, any myocardial infarction, or any revascularization, was similar among patients treated with large or smaller coronary stents. The impact of DES versus BMS implantation was consistent irrespective of the stent size both for the primary end point (POur results do not support the preferential use of BMS for patients with large coronary vessels. DES may warrant improved efficacy irrespective of stent size among patients undergoing primary percutaneous coronary intervention.URL: https://www.clinicaltrials.gov. Unique identifier: NCT00828087.

Background Data of long-term safety and efficacy of the COMBO dual-therapy stent is lacking. REMEDEE Registry evaluated the COMBO stent and showed low clinical event rates up to 3 year. We report the clinical outcomes at 4-year follow-up of this registry. Methods The REMEDEE Registry is a prospective, multicenter registry with minimal exclusion criteria, evaluating clinical outcomes after treatment with the COMBO stent. A 1000 patients were enrolled between June 2013 and March 2014. Target lesion failure (TLF), defined as a composite of cardiac death, target-vessel myocardial infarction (TV-MI) and target lesion revascularization (TLR), at 4-year follow-up was the primary focus of this analysis. Results Four-year follow-up data were obtained in 97.3% of patients. TLF was present in 117 patients (11.9%). Cardiac death occurred in 45 patients (4.6%), TV-MI was observed in 25 patients (2.6%) and TLR was performed in 73 patients (7.5%). Of the 7.5% TLR at 4 years, 1.5% were beyond 2 years. Definite ST was seen in 7 patients (0.7%) and probable ST in 1 (0.1%). No definite or probable ST occurred between 3 and 4 years follow-up. At 4-year follow-up, 93.1% of patients were free of ischemic symptoms. Conclusion This registry showed excellent 4-year results after COMBO stent placement, with no ST beyond 3 years.

Background: Drug-eluting stents (DES) showed improved efficacy and safety compared with bare-metal stents (BMS), and international guidelines recommend their use as first line treatment. Yet, BMS are still widely used in practice, especially in large coronary vessels. We aimed to compare efficacy and safety of second-generation DES over BMS in large coronary culprit ST-segment elevated myocardial infarction lesions. Methods: We evaluated impact of large coronary stents (maximum size ≥3.50 mm) or smaller stents ( Results: Large coronary stents were used in 683 patients (45.9%). At 5-year follow-up, the crude rate of the primary end point, a composite of all-cause death, any myocardial infarction, or any revascularization, was similar among patients treated with large or smaller coronary stents. The impact of DES versus BMS implantation was consistent irrespective of the stent size both for the primary end point ( P int =0.82) and other secondary ischemic end points. Within patients treated with bigger stents, DES implantation was associated to a trend toward a reduction of target lesion (hazard ratio, 0.53; 95% CI, 0.27–1.02; P =0.05) and target vessel revascularization (hazard ratio, 0.60; 95% CI, 0.34–1.03; P =0.066). Conclusions: Our results do not support the preferential use of BMS for patients with large coronary vessels. DES may warrant improved efficacy irrespective of stent size among patients undergoing primary percutaneous coronary intervention. Clinical Trial Registration: URL: https://www.clinicaltrials.gov .

BackgroundThe COMBO stent is a biodegradable-polymer sirolimus-eluting stent with endothelial progenitor cell capture technology for faster endothelialization. ObjectiveWe analyzed COMBO stent outcomes in relation to bleeding risk using the PARIS bleeding score. MethodsMASCOT was an international registry of all-comers undergoing attempted COMBO stent implantation. We stratified patients as low bleeding-risk (LBR) for PARIS score≤3 and intermediate-to-high (IHBR) for score>3 based on baseline age, body mass index, anemia, current smoking, chronic kidney disease and need for triple therapy. Primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, myocardial infarction (MI) not clearly attributed to a non-target vessel or clinically-driven target lesion revascularization (TLR). Bleeding was adjudicated using the Bleeding Academic Research Consortium (BARC) definition. Dual antiplatelet therapy (DAPT) cessation was independently adjudicated. Results The study included 56% (n=1270) LBR and 44% (n=1009) IHBR patients. Incidence of 1-year TLF was higher in IHBR patients (4.1% vs. 2.6%, p=0.047) driven by cardiac death (1.7% vs. 0.7%, p=0.029) with similar rates of MI (1.8% vs. 1.1%, p=0.17), TLR (1.5% vs. 1.6%, p=0.89) and definite/ probable stent thrombosis (1.2% vs. 0.6%, p=0.16). Incidence of 1-year major BARC 3 or 5 bleeding was significantly higher in IHBR patients (2.3% vs. 0.9%, p=0.0094), as was the incidence of DAPT cessation (29.3% vs. 22.8%, p Conclusion Patients with intermediate-to-high PARIS bleeding risk in the MASCOT registry experienced greater incidence of 1-year TLF, major bleeding and DAPT cessation than LBR patients, without significant differences in stent thrombosis.

Objectives This registry evaluated the safety and clinical outcomes of the Combo stent in an all-comers population in routine clinical practice. We report 1-year results. Background Limitations of current generation drug-eluting stents (DES) are 3-fold: stent thrombosis, neoatherosclerosis related to impaired healing, and repeat revascularization due to (late-) in-stent restenosis. The Combo stent combines an abluminal biodegradable coating eluting sirolimus and a luminal anti-CD34+ antibody layer to attract endothelial progenitor cells in order to promote vessel healing, thus preventing neointima formation and restenosis. Methods The REMEDEE (Randomized study to Evaluate the safety and effectiveness of an abluMinal sirolimus coatED bio-Engineered StEnt) post-market registry was an international, multicenter, prospective trial that evaluated clinical outcomes after deployment of the Combo stent, in an all-comers population of patients treated with a Combo stent in the setting of routine clinical care. Clinical endpoints were target lesion failure (TLF), defined as a composite of cardiac death, nonfatal myocardial infarction (MI), or target lesion revascularization (TLR). Results Between June 2013 and March 2014, a total of 1,000 patients were included in the registry, 49.9% of whom presented with acute coronary syndrome. Mean age was 65 ± 11 years old (range: 34 to 94 years of age), and 74% of patients were male; 58.9% of 1,255 lesions were American Heart Association type B2 or C lesions. The primary endpoints were 5.7% TLF, 1.7% cardiac death, 0.7% target vessel MI, and 4.4% TLR. Definite stent thrombosis occurred in 0.5% of subjects; no thrombosis occurred after 9 days post-stenting. Conclusions This registry showed excellent 1-year results of novel Combo bioengineered stent technology in an all-comers patient population.

Aims Our aim was to assess the performance of the Direct Flow Medical (DFM) repositionable and retrievable transcatheter aortic valve implantation (TAVI) system in high-risk patients with severe aortic stenosis. Methods and results One hundred and five consecutive high-risk patients with severe aortic stenosis undergoing TAVI with the DFM prosthesis were enrolled in six high-volume TAVI centres in Germany, Italy, The Netherlands, Belgium, and Luxembourg. The "inner curve" technique was systematically used in all patients. The primary endpoint was all-cause mortality at 30 days of clinical follow-up. Secondary endpoints for the same time frame were: (i) VARC-2-defined patient safety; and (ii) VARC-2-defined device success. The primary endpoint of all-cause mortality at 30 days was met in 1.9% (two patients). The VARC-2-defined device success rate was 98.1%. The combined patient safety endpoint was met in 88.6%. Residual moderate aortic regurgitation was observed in 1.9% (two patients). Permanent pacemaker implantation due to post-procedural persistent advanced atrioventricular block was performed in 9.5% (10 patients). Conclusions In a multicentre, real-world clinical setting of high-risk patients with severe aortic stenosis, a repositionable and retrievable TAVI system was effective and safe in the short-term follow-up.

Background Use of everolimus-eluting stents (EES) has proven to be clinically effective and safe in patients with ST-segment elevation myocardial infarction but it remains unclear whether it is cost-effective compared to bare-metal stents (BMS) in the long-term. We sought to assess the cost-effectiveness of EES versus BMS based on the 5-year results of the EXAMINATION trial, from a Spanish health service perspective. Methods Decision analysis of the use of EES versus BMS was based on the patient-level clinical outcome data of the EXAMINATION trial. The analysis adopted a lifelong time horizon, assuming that long-term survival was independent of the initial treatment strategy after the end of follow-up. Life-expectancy, health-state utility scores and unit costs were extracted from published literature and publicly available sources. Non-parametric bootstrapping was combined with probabilistic sensitivity analysis to co-assess the impact of patient-level variation and parameter uncertainty. The main outcomes were total costs and quality-adjusted life-years. The incremental cost-effectiveness ratio was expressed as cost per quality-adjusted life-years gained. Costs and effects were discounted at 3%. Results The model predicted an average survival time in patients receiving EES and BMS of 10.52 and 10.38 undiscounted years, respectively. Over the life-long time horizon, the EES strategy was (sic)430 more costly than BMS ((sic) 8,305 vs. (sic)7,874), but went along with incremental gains of 0.10 quality-adjusted life-years. This resulted in an average incremental cost-effectiveness ratio over all simulations of (sic)3,948 per quality-adjusted life-years gained and was below a willingness-to-pay threshold of (sic)25,000 per quality-adjusted life-years gained in 86.9% of simulation runs. Conclusions Despite higher total costs relative to BMS, EES appeared to be a cost-effective therapy for ST-segment elevation myocardial infarction patients due to their incremental effectiveness. Predicted incremental cost-effectiveness ratios were below generally acceptable threshold values., The EXAMINATION trial (NCT00828087) was funded by the Spanish Heart Foundation.

Acute thrombotic occlusion may lead to major life-threatening syndromes such as ST-segment elevation myocardial infarction (STEMI) or stroke. In most patients, the underlying pathophysiology may be related to local vascular factors or thrombotic emboli. Thrombus composition might be indicative of

Analyses of thrombi of patients with ST-segment elevation myocardial infarction (STEMI) showed, in addition to fresh thrombi, also a prevalence of relatively old thrombi. Old thrombi were present in up to 50% of patients with STEMI and associated with a worse prognosis. No data are available

Background The COMBO stent (OrbusNeich Medical, Ft. Lauderdale, Florida) is a new-generation bio-engineered drug eluting stent, combining an abluminal coating of a bioabsorbable polymer matrix for sustained release of sirolimus and luminal anti-CD34 coating for endothelial progenitor cell capture and rapid endothelialization. Methods The Multinational Abluminal Sirolimus Coated BiO-Engineered StenT (MASCOT) registry was a prospective post-marketing study conducted from June 2014–May 2017 across 60 centers globally. Patients were eligible if COMBO stent implantation was attempted, and they received dual antiplatelet therapy (DAPT) per local guidelines. Follow-up was conducted by trained research staff at 1, 6 and 12 months by phone or clinic visit to capture clinical events and DAPT cessation events. The primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, non-fatal myocardial infarction not clearly attributable to a non-target vessel, or ischemia-driven target lesion revascularization. Results A total of 2614 patients were enrolled over the study period with 96.7% completion of 1-year follow-up. The mean age of enrolled patients was 62.9 ± 11.2 years and 23.0% were female. Diabetes mellitus was present at baseline in 33.5%. A total of 56.1% patients underwent PCI for acute coronary syndrome (ACS). The 1-year primary endpoint of TLF occurred in 3.4% patients (n = 88). Definite stent thrombosis occurred in 0.5% patients (n = 12). Conclusion The MASCOT post marketing registry provides comprehensive safety and efficacy outcomes following contemporary PCI using the novel COMBO stent in an all-comer population. This platform is associated with low rates of 1-year TLF and ST. Clinicaltrials.gov identifier NCT02183454 .

Percutaneous coronary interventions (PCI) have become a reliable revascularisation option to treat ischaemic coronary artery disease. Drug-eluting stents (DES) are widely used as first choice devices in many procedures due to their established good medium to long term outcomes. These permanent implants, however, do not have any residual function after vascular healing following the PCI. Beyond this initial healing period, metallic stents may induce new problems, resulting in an average rate of 2 % reinterventions per year. To eliminate this potential late limitation of permanent metallic DES, bioresorbable coronary stents or 'vascular scaffolds' (BVS) have been developed. In a parallel publication in this journal, an overview of the current clinical performance of these scaffolds is presented. As these scaffolds are currently CE marked and commercially available in many countries and as clinical evidence is still limited, recommendations for their general usage are needed to allow successful clinical introduction.

While the effects of mindfulness are increasingly explored across different fields, little is known about the application of these practices in agile project teams. In this paper we report on a rigorous controlled trial executed to understand the impact of the three minute breathing exercise on the perceived effectiveness of stand-up meetings. We compare (1) an active group using a three minute breathing exercise, to (2) a placebo, and (3) a control group in 3 organizations and 8 teams with over 152 measurements. Our findings indicate an immediate positive impact on perceived effectiveness, decision-making and improved listening in the active groups compared to the placebo and natural history groups. We provide a preliminary agenda for future research based on our findings and previous evidence from other fields.

Contains fulltext : 176952.pdf (Publisher’s version ) (Open Access) OBJECTIVE: The dual-therapy stent combines an abluminal biodegradable drug-eluting coating, with a 'pro-healing' luminal layer. This bioengineered layer attracts circulating endothelial progenitor cells that can differentiate into normal endothelium. Rapid endothelialisation of the stent might allow safe short dual antiplatelet therapy. We aim to assess clinical outcomes in patients treated with this novel device at 2-year follow-up. METHODS: A total of 1000 patients were included in the REMEDEE Registry to evaluate clinical outcomes after treatment with the dual-therapy stent. This prospective, multicentre, European registry included all-comers patients, which resulted in a high-risk patient population. Target lesion failure (TLF), a combined endpoint consisting of cardiac death, target vessel myocardial infarction (tv-MI) and target lesion revascularisation (TLR), at 2-year follow-up was the primary focus of this analysis. Subgroup analyses were performed according to diabetes mellitus (DM), gender, age, acute coronary syndrome, smoking, hypertension, hypercholesterolaemia, previous stroke, peripheral vascular disease and chronic renal failure. RESULTS: TLF at 2 years was observed in 84 patients (8.5%), with 3.0% cardiac death, 1.2% tv-MI and 5.9% TLR. Definite stent thrombosis at 2 years was 0.6%. In the presence of DM or chronic renal failure, a higher TLF was observed. CONCLUSIONS: The dual-therapy stent shows favourable clinical outcomes from 12 months onwards. Two years after stent placement, low TLF and very low stent thrombosis rates are observed in this large prospective all-comers cohort study. TRIAL REGISTRATION NUMBER: NCT01874002; Results.

Patients with high body mass index (BMI) seem to have better outcomes after percutaneous coronary intervention than normal-weight patients. However, contrasting results have been reported on the "obesity paradox" in patients presenting with ST-elevation myocardial infarction (STEMI). The aim of our study was to investigate the impact of BMI on mortality in the population enrolled in the Evaluation of the Xience-V stent in Acute Myocardial INfArcTION (EXAMINATION) trial. The EXAMINATION trial randomized 1,498 patients with STEMI to a bare-metal stent or an everolimus-eluting stent. In this substudy patients were stratified into 3 groups according to BMI values: normal (BMI < 25 kg/m(2)), overweight (BMI = 25 to 29.9 kg/m(2)), and obese (BMI 30 kg/m(2)). The coprimary end points were the all-cause and cardiac deaths among the groups at the 5-year follow-up. BMI was available in 1,421 patients, divided in 401 (28.2%) normal, 702 (49.4%) overweight, and 318 (22.4%) obese. Obese patients were younger (p = 0.012) compared with the other groups, but with a worse cardiovascular risk profile. They were more frequently female (p

This analysis investigates the 5-year outcomes of the biodegradable polymer biolimus-eluting stent (BP-BES) and durable polymer everolimus-eluting stent (DP-EES) in an all-comers population undergoing percutaneous coronary intervention.Recent 1- and 3-year results from randomized trials have indicated similar safety and efficacy outcomes of BP-BES and DP-EES. Whether benefits of the biodegradable polymer device arise over longer follow-up is unknown. Moreover, in-depth, prospective, long-term follow-up data on metallic drug-eluting stents with durable or biodegradable polymers are scarce.The COMPARE II trial (Abluminal Biodegradable Polymer Biolimus-Eluting Stent Versus Durable Polymer Everolimus-Eluting Stent) was a prospective, randomized, multicenter, all-comers trial in which 2,707 patients were randomly allocated (2:1) to BP-BES or DP-EES. The pre-specified endpoint at 5 years was major adverse cardiac events, a composite of cardiac death, nonfatal myocardial infarction, or target vessel revascularization.Five-year follow-up was available in 2,657 patients (98%). At 5 years, major adverse cardiac events occurred in 310 patients (17.3%) in the BP-BES group and 142 patients (15.6%) in the DP-EES group (p = 0.26). The rate of the combined safety endpoint all-cause death or myocardial infarction was 15.0% in the BP-BES group versus 14.8% in the DP-EES group (p = 0.90), whereas the efficacy measure target vessel revascularization was 10.6% versus 9.0% (p = 0.18), respectively. Interestingly, definite stent thrombosis rates did not differ between groups (1.5% for BP-BES vs. 0.9% for DP-EES; p = 0.17).The 5-year analysis comparing biodegradable polymer-coated BES and the durable polymer-coated EES confirms the initial early- and mid-term results regarding similar safety and efficacy outcomes in this all-comers percutaneous coronary intervention population.
