Temporal trends in coronary intervention strategies and the impact on one-year clinical events: data from a Japanese multi-center real-world cohort study
AbstractPercutaneous coronary intervention (PCI) has significantly advanced over the last 40  years, but it is not clear whether there have been any changes in prognosis in recent years. The Kumamoto Intervention Conference Study Real-World Registry is a multi-center registry that enrolls consecutive patients undergoing PCI in 17 centers in Kyushu, Japan. To elucidate the clinical impact o f recent changes in treatment strategies, 8841 consecutive participants (historical PCI:n = 4038, enrolled between January 2013 and December 2014, and current PCI:n = 4803, between January 2015 and March 2017) with 1-year follow...

Efficacy of the Wolverine cutting balloon on a circumferential calcified coronary lesion: Bench test using a three-dimensional printer and computer simulation with the finite element method
This study aimed to explore the optimal method of dilation of highly calcified lesions using a cutting balloon. Calcification models were developed from patient computed tomography and intravascular ultrasound data, and were constructed using three-dimensional printers. The lesions were dilated using a Wolverine ™ cutting balloon and NC Emerge™ noncompliant balloon catheter, and the success rate of dilation and maximum dilation pressure were compared. The maximum first principal stresses in calcified lesions were also evaluated by computer simulation using the finite element method. In the bench test, t he dilation suc...

Factors associated with long-term major adverse cardiac events of coronary bioresorbable vascular scaffold
AbstractThe long-term clinical outcomes after implantation of bioresorbable vascular scaffolds (BVS) in a real-world cohort were not well described. To identify factors associated with major adverse cardiovascular events (MACE) on long-term follow-up after implantation of BVS in patients undergoing elective percutaneous coronary intervention (PCI). This was an observational study based on a hospital registry of percutaneous coronary intervention. Participants were consecutive patients who underwent PCI and implanted with at least one everolimus-eluting BVS (Absorb®) in a single center between 2014 and 2017. Among the 170 ...

Early hemodynamic changes after transcatheter aortic valve implantation in patients with severe aortic stenosis measured by invasive pressure volume loop analysis
AbstractReplacement of a stenotic aortic valve reduces immediately the ventricular to aortic gradient and is expected to improve diastolic and systolic left ventricular function over the long term. However, the hemodynamic changes immediately after valve implantation are so far poorly understood. Within this pilot study, we performed an invasive pressure volume loop analysis to describe the early hemodynamic changes after transcatheter aortic valve implantation (TAVI) with self-expandable prostheses. Invasive left ventricular pressure volume loop analysis was performed in 8 patients with aortic stenosis (mean 81.3  years)...

Mechanisms of drug-eluting stent restenosis
AbstractDrug-eluting stents (DES) were developed to overcome in-stent restenosis (ISR), which has long been considered the main complication limiting the long-term efficacy of coronary stenting. New-generation DES which composed of advanced stent design with and without specific biocompatible polymer contributes a reduction of the incidence of ISR to rate ranging from 5 to 10%. The precise reasons of DES restenosis are still controversial and not fully understood. Angiographic and coronary images at the index procedure, systemic status of patients, medications, and intracoronary imaging at ISR site are all considered to fi...

Clinical outcomes of transcatheter aortic valve implantation in failed bioprosthetic surgical valves vs. native aortic stenosis: insights from a meta-analysis
AbstractThere is no meta-analysis comparing clinical outcomes between valve-in-valve transcatheter aortic valve implantation for failed surgical bioprosthetic valves (ViV-TAVI) and native valve TAVI for aortic stenosis (NV-TAVI). We aimed to investigate clinical outcomes between ViV-TAVI and NV-TAVI using a meta-analysis. EMBASE and MEDLINE were searched through April 2020 to investigate the comparative outcomes between ViV-TAVI and NV-TAVI. The main outcomes were short-term (30-day/in-hospital) mortality, pacemaker implantation (PMI), life threatening and/or major bleeding, stroke, and coronary obstruction, and long-term ...

Influence of CYP2C19 genotypes for the effect of 1-month dual antiplatelet therapy followed by clopidogrel monotherapy relative to 12-month dual antiplatelet therapy on clinical outcomes after percutaneous coronary intervention: a genetic substudy from the STOPDAPT-2
In conclusion, for the selected patients in STOPDAPT-2 trial, CYP2C19 LOF alleles had no significant, consistent interaction with the effect of 1-month DAPT relative to 12-month DAPT for clinical outcomes, although the study was overtly underpowered.Trial registrySTOPDAPT-2 ClinicalTrials.gov number, NCT02619760.
