Found 20 clinical trials
Test
In this prospective cohort study, 250 patients with suspected or known CAD and at least one intermediate coronary lesion (50-70% stenosis) who had a NiFFR value greater than 0.80 underwent coronary computed tomography angiography (CCTA) with NiFFR assessment. Patients were followed for one year to monitor for MACE

Morphological Parameters of In-stent RESTenosis Assessed and Identified by OCT
OCT during angiography provides a detailed analysis of the stents and potential complications: the presence of neoatherosclerosis with or without plaque rupture, intimal hyperplasia, stent under-deployment, stent fracture and distal or proximal progression of the atherosclerosis.

Efficacy and Safety of SP-8203 in Patients With Ischemic Stroke Requiring rtPA
This clinical trial is designed to evaluate the efficacy and safety of the combination therapy of SP-8203 (Otaplimastat) and recombinant tissue Plasminogen Activator (rtPA) standard of care. In this clinical trial, rtPA will be injected intravenously using an infusion device. If reperfusion is not occur in spite of rtPA therapy, …

MRI Assessing Clinical Usability of STrategically Acquired Gradient Echo on Human Participants
The study's purpose is to validate STAGE images and, when applicable, their equivalence to conventional MRI through an assessment by a trained certified neuroradiologist in a clinical setting. For STAGE images without conventional equivalent, the neuroradiologist will determine if their contrasts, intensities, and quality are sufficient and meet expectations for …

Deciphering AMD by Deep Phenotyping and Machine Learning- Prospective Study - PINNACLE
We will conduct a prospective non-interventional study including 400 early AMD patients (=600 untreated early AMD eyes, including both unilateral (AREDS IV) and bilateral (AREDS II)) over 3 years to specifically investigate the morphological sequence of events preceding the conversion towards late AMD. All patients will be followed by OCT …

Assessment of Paravalvular Leak After TAVI by Hemodynamic Measurements and Cardiac MRI
Grading paravalvular leakage after TAVI is difficult. Echocardiography and angiography systematically underestimate paravalvular leakage (PVL) as compared to cardiac MRI. Hemodynamic measurements are used to aid decision making directly after TAVI implantation.
