Image Content Analysis of Dural-axis Rotational Versus Standard Coronary Angiography
Coronary Artery DiseaseThe investigators hypothesized that dual-axis rotational coronary angiography was non-inferior to standard coronary angiography with respect to diagnosis of coronary artery disease.
A Randomized Comparison of Clinical Outcomes Between Everolimus-eluting Bioresorbable Vascular Scaffold...
Coronary Artery DiseasePCI of diffuse long coronary lesions still remains challenging because of relatively high risk of in-stent restenosis and stent thrombosis compared to short coronary lesions. The purpose of the study is to compare an incidence of composite of major adverse cardiovascular events (MACEs) at 1 year between Absorb everolimus-eluting BVS and Xience EES after coronary intervention in long lesions.
Prevalence and Screening of Abdominal Aortic Aneurysms Among Men With Coronary Artery Disease
Abdominal Aortic AneurysmThe purpose of this study is to investigate the prevalence of abdominal aortic aneurysms (AAA) among male patients with coronary artery disease (CAD) verified in coronary angiography. Ethiology of AAA is known to be common with atherosclerotic arterial diseases (coronary artery disease, peripheral artery disease and carotid artery disease), so the hypothesis is that AAA should be more common among these CAD patients, thus making screening of these patients (for AAA) more cost-efficient. Study will be carried out as a multi-center prospective screening study. Data will be collected in North Karelia Central Hospital, Kuopio University Hospital and Tampere University Hospital. Data consists of 200 consecutive coronary angiography patients in each hospital, resulting in 600 patients in total. All male patients with diagnosed CAD will be recruited for the study and screened for AAA with ultrasound. Nevertheless, patients with previously known AAA will be excluded from the study.
Gadobutrol / Gadavist-enhanced Cardiac Magnetic Resonance Imaging (CMRI) to Detect Coronary Artery...
Coronary Artery DiseaseSubjects being evaluated for suspected or known Coronary artery Disease (CAD) based on signs and/or symptoms, will be invited to participate in the study. The duration for a subject in the study may range from 2 days to 4-6 weeks. One to four visits to the study doctor will be required. The primary objective of this study is to demonstrate that sensitivity and specificity of gadobutrol-enhanced cardiac magnetic resonance imaging (CMRI) exceed pre-specified minimum performance thresholds of 60% and 55%, respectively, and to show superior sensitivity over unenhanced wall motion CMRI at vasodilator rest/stress for the detection of significant CAD. The CMR images acquired with a uniform imaging acquisition software will be evaluated either against the results from routine clinical Coronary Angiography (CA) or Computed Tomography Angiography (CTA), which are the standard of reference. CMRI and CA/CTA images will be collected for an independent image review (blinded read).
Relation Among Shear Stress Distribution, Stent Design, and Subsequent Vessel Healing After Drug-eluting...
Coronary Heart DiseaseThe purpose of this study is to evaluate the differences of wall shear stress distribution among different types of drug-eluting stents and its impact on vessel healing evaluated by intravascular optical coherence tomography evaluation.
Prospective, Randomized, Multicenter Study to Assess the Safety and Effectiveness of the Orsiro...
Coronary Artery DiseaseBIOFLOW-IV is a prospective, international, multicenter, randomised controlled trial. The purpose of this trial is to compare the Biotronik Orsiro drug eluting stent system with the Xience Prime / Xience Xpedition (Xience)drug eluting stent system in de novo coronary lesions. The study is powered for non-inferiority with respect to Target Vessel Failure(TVF)at 12 months.
Stress-MRI Assessment After Right Coronary Artery CTO Recanalization
Ischemic Heart DiseaseCoronary Atherosclerosis2 moreThe hypothesis of this study is that Stress-MRI is a clinically significant method of myocardial perfusion assessment after coronary angioplasty with stenting of right coronary artery (RCA) chronic total occlusion (CTO) is performed.
COmplex Bifurcation PCI: AXXESS Device + Absorb BVS, vs Modified T Stenting With Absorb BVS
Coronary Artery DiseaseComparison of healing responses after treatment of complex bifurcation lesions with a dedicated bifurcation device (Axxess™ Biolimus Eluting Coronary Bifurcation Stent System + Absorb BVS in the distal branches) versus the Modified T stenting technique using Absorb BVS: an optical coherence tomography (OCT) analysis.
The Assessment of Progression of Paroxysmal AF After CABG
Paroxysmal Atrial FibrillationCoronary Artery DiseaseThe aim of this study is a comparative evaluation of progression of paroxysmal atrial fibrillation in patients with coronary artery disease after isolated CABG and CABG combined with pulmonary vein isolation. Hypothesis of the study - patients with paroxysmal atrial fibrillation and coronary artery disease after CABG in combination with isolation of the pulmonary veins have a better outcomes for the progression of AF compared with patients undergoing isolated CABG.
Xenetix® 350: Comparative Assessment of Image Quality for Coronary CT Angiography
Coronary Artery DiseaseThe purpose of this study is to demonstrate the (statistical) non-inferiority of iobitridol (Xenetix® 350) when compared to contrast agents with higher iodine concentrations, iopromide (Ultravist® 370) and iomeprol (Iomeron® 400) in terms of coronary CT scan evaluability (quality and interpretability of images).
