Filter by:This is a self-controlled cohort study to evaluate the efficacy and safety of comprehensive treatment in patients with inflammation-associated rapidly-progressive coronary artery disease (IR-CAD) by comparing the study endpoints before treatment with those after treatment in the same group of patients.
Prospective, randomised, open-label, international multicenter trial to evaluate the safety and efficacy of drug-coated balloon (DCB) treatment compared to drug-eluting stenting (DES) in patients with large coronary artery disease.
The objective of this randomized study was to compare outcomes of imaging-and physiology-guided state-of-the-art ercutaneous coronary intervention (PCI) to coronary artery bypass grafting (CABG) in patients with diabetes and three-vessel CAD (not involving left main).
A pragmatic, prospective, multi-center, open label, randomized controlled, superiority trial. The study will compare clinical outcomes between invasive versus non-invasive approach as next diagnostic step in symptomatic patients with non-high risk obstructive coronary artery disease (CAD) on coronary computed tomography-angiography (CCTA).
Authors hypothesize that "no-touch" saphenous vein as I graft is superior over conventional "no-touch" saphenous vein as free graft in the incidence of graft patency.
To establish if the cardiac radiation dose assesment is well aproximated with routine 3D CT scan compared to 4D CT experimental scan with respiratory gating (breath motion monitoring). The study population relates to left side breast cancers female patients that require a radiation therapy treatment.
This study aims to evaluate procedural and clinical outcomes of acute coronay syndrome (ACS) patients with aneurysmatic culprit right coronary artery (RCA).
This study aims to evaluate the clinical value of a novel CT gantry supporting a .23 second rotation time and systematically compare it with 0.23 second rotation time, in patients with clinically indicated aortic CTA in the workup of aortic stenosis. Patients will be randomly assigned .23 or .28 sec rotation time CTA. Coronary artery interpretability rates will be determined in both groups.
This is a prospective, multicenter, randomized controlled clinical investigation aiming to evaluate the safety and effectiveness of non-slip balloon catheter for the treatment of patients with coronary artery stenosis.
Coronary CT angiography is challenging in patients with more than mildly calcified coronary vessels, because of calcium artefacts that prevents evaluation of the lumen. The purpose of the CCT-PCD-1-study is to evaluate the diagnostic accuracy and image quality in coronary CT angiography using a commercially available CT system equipped with a photon counting detector technology. Patients referred for cardiac CT and conventional coronary angiography as part of routine preoperative evaluation before Transcatheter Aortic Valve Implantation (TAVI) will be asked for inclusion in the study. This group of patients has generally a coronary artery calcium burden and perform cardiac CT and coronary angiography as part of routine care. The diagnostic accuracy concerning significant coronary artery stenosis on the preoperative CT will be evaluated with the conventional coronary angiography as reference. Also, CT examination image quality will be evaluated.
