Choice of CTO scores to predict procedural success in clinical practice. A comparison of 4 different CTO PCI scores in a comprehensive national regis…
2021
Background We aimed to compare the performance of the recent CASTLE score to J-CTO, CL and PROGRESS CTO scores in a comprehensive database of percutaneous coronary intervention of chronic total occlusion procedures. Methods Scores were calculated using raw data from 1,342 chronic total occlusion procedures included in REBECO Registry that includes learning and expert operators. Calibration, discrimination and reclassification were evaluated and compared. Results Mean score values were: CASTLE 1.60±1.10, J-CTO 2.15±1.24, PROGRESS 1.68±0.94 and CL 2.52±1.52 points. The overall percutaneous coronary intervention success rate was 77.8%. Calibration was good for CASTLE and CL, but not for J-CTO…
Survival benefit from recent changes in management of men and women with ST-segment elevation myocardial infarction treated with percutaneous coronar…
2019
Background: Nowadays, the majority of patients with myocardial infarction with ST-segment elevation (STEMI) are treated with primary percutaneous coronary interventions (PCI). In recent years, there have been ongoing improvements in PCI techniques, devices and concomitant pharmacotherapy. However, reports on further mortality reduction among PCI-treated STEMI patients remain inconclusive. The aim of this study was to compare changes in management and mortality in PCI-treated STEMI patients between 2005 and 2011 in a real-life setting. Methods: Data on 79,522 PCI-treated patients with STEMI from Polish Registry of Acute Coronary Syndromes (PL-ACS) admitted to Polish hospitals between 2005 an…
Epigenetic upregulation of endogenous VEGF-A reduces myocardial infarct size in mice.
2014
“Epigenetherapy” alters epigenetic status of the targeted chromatin and modifies expression of the endogenous therapeutic gene. In this study we used lentiviral in vivo delivery of small hairpin RNA (shRNA) into hearts in a murine infarction model. shRNA complementary to the promoter of vascular endothelial growth factor (VEGF-A) was able to upregulate endogenous VEGF-A expression. Histological and multiphoton microscope analysis confirmed the therapeutic effect in the transduced hearts. Magnetic resonance imaging (MRI) showed in vivo that the infarct size was significantly reduced in the treatment group 14 days after the epigenetherapy. Importantly, we show that promoter-targeted shRNA upr…
Definitions and Clinical Trial Design Principles for Coronary Artery Chronic Total Occlusion Therapies: CTO-ARC Consensus Recommendations.
2021
Over the past 2 decades, chronic total occlusion (CTO) percutaneous coronary intervention has developed into its own subspecialty of interventional cardiology. Dedicated terminology, techniques, devices, courses, and training programs have enabled progressive advancements. However, only a few randomized trials have been performed to evaluate the safety and efficacy of CTO percutaneous coronary intervention. Moreover, several published observational studies have shown conflicting data. Part of the paucity of clinical data stems from the fact that prior studies have been suboptimally designed and performed. The absence of standardized end points and the discrepancy in definitions also prevent…
Noninvasive Visualization of an Apparent Patent Intracoronary Stent by Transesophageal Echocardiography
1995
In the area of increasing interventional techniques there is a need for noninvasive imaging modalities to provide postinterventional follow-up. We were able to visualize the apparent patency and measure the dimensions of an intracoronary Palmaz-Schatz stent in the left circumflex coronary artery using transesophageal two-dimensional echocardiography. This report indicates the potential of echocardiography to directly assess coronary stents.
Bioresorbable polymer-coated thin strut sirolimus-eluting stent vs durable polymer-coated everolimus-eluting stent in daily clinical practice: Propen…
2018
Objectives We sought to determine the 1-year clinical follow-up in patients treated with the thin strut (71 μm) bioabsorbable polymer-coated sirolimus-eluting stent (BP-SES) vs durable coating everolimus eluting stent (DP-EES) in daily clinical routine. Background Presence of durable polymers may be associated with late/very late stent thrombosis occurrence and the need for prolonged dual antiplatelet therapy. Bioabsorbable polymers may facilitate stent healing, thus enhancing clinical safety. Methods Interventional Cardiology Network Registry is a prospective, multicenter, observational registry of 21,400 consecutive patients treated with PCI since 2010. We analyzed 4,670 patients treated …
Carotid artery stenting outcomes in high-risk patients receiving best medical therapy: results from a single high-volume interventional cardiology pr…
2016
Kontext: Implantace stentů do karotických tepen (carotid artery stenting, CAS) se v soucasnosti ve velkem měřitku použiva v lecbě stenozy karotických tepen. Klinicke studie z posledni doby prokazaly nizkou incidenci přihod po CAS. Tato studie hodnoti 30denni a rocni výsledky pacientů lecených pro CAS intenzivni farmakoterapii na pracovisti provadějicim vysoke pocty perkutannich koronarnich intervenci rocně.Metoda: V obdobi od ledna 2011 do prosince 2013 byla CAS provedena celkem u 184 pacientů. Mimo protidestickove lecby byla provaděna i intenzivni antihypertenzni lecba spolu s vysoce intenzivni terapii statiny a lecbou zaměřenou na normalizaci srdecni frekvence. Pacienti byli stratifikovan…
In-Stent Restenosis: Definition, Entity of the Problem, Etiopathogenesis and Treatment Options
2018
In-stent restenosis (ISR) still represents a frequent limitation of percutaneous coronary intervention despite the introduction of latest-generation drug-eluting stents (DES), drastically lowering the overall incidence of ISR. Thus, the treatment of DES ISR remains a real brainteaser for interventional cardiologists.
058 THE ROLE OF FEMALE SEX IN THE CONTEMPORARY TREATMENT OF THE LEFT MAIN CORONARY ARTERY INSIGHTS FROM THE W-DELTA (WOMEN-DRUG ELUTING STENT FOR LEF…
2013
Background The optimal revascularization strategy of women with unprotected left main coronary artery (ULMCA) disease is unknown. Therefore, the aim of this study was to evaluate long-term clinical outcomes in this cohort treated with percutaneous coronary intervention (PCI) utilising drug-eluting stents (DES) versus coronary artery bypass grafting (CABG). Methods All consecutive women from the Drug Eluting stent for LefT main coronary Artery disease (DELTA) Registry with ULMCA disease treated by PCI with DES or CABG were analysed. A propensity matching was performed to adjust for baseline differences between the 2 treatment groups. Results In total, 818 women were included: 489 (59.8%) und…
Biodegradable polymer-coated thin strut sirolimus- -eluting stent versus durable polymer-coated everolimus-eluting stent in the diabetic population.
2021
Background: The number of patients with diabetes mellitus (DM) presenting with coronary artery disease is increasing and accounts for more than 30% of patients undergoing percutaneous coronary interventions (PCI). The biodegradable polymer drug-eluting stents were developed to improve vascular healing. It was sought herein, to determine 1-year clinical follow-up in patients with DM treated with the thin strut biodegradable polymer-coated sirolimus-eluting stent (BP-SES) versus durable coating everolimus-eluting stent (DP-EES). Methods: Patients were retrospectively analyzed with DM were treated with either a BP-SES (ALEX™, Balton, Poland, n = 670) or a DP-EES (XIENCE™, Abbott, USA, n = 884)…
