ELUCIDATE FFRct Study
The goal of this study is to evaluate the diagnostic accuracy of a novel plaque-based coronary CT angiography (CCTA) fractional flow reserve (FFRct) software device for the estimation of invasive fractional flow reserve (FFR). Researchers will compare the Elucid plaque-based FFRct analysis to invasively measured FFR in patients who have …
High Frame Rate Ultrasound in Heart Disease Assessment
The study will compare standard ultrasound images to high frame rate ultrasound images in patients with heart disease or with a low risk of heart disease to see if a higher frame rate of ultrasound adds to the information obtained from standard ultrasound.
The COMPLETE Study
The COMPLETE study is a single-centre, investigator-initiated study of patients with an indication for invasive coronary angiography with CCTA performed during the diagnostic evaluation. After identifying the presence of a coronary stenosis, defined as an epicardial lesion >50% stenosis on CCTA, patients eligible for the study will be invited to …
Physiological Assessment of Severe Coronary Stenosis for Informing Planned PCI
Traditionally, the severity of a blockage (stenosis) in a coronary artery has been determined by visual angiographic assessment of the diameter of the artery at the level of a blockage compared to a normal healthy area of the same artery. With the advent of invasive physiological testing to assess coronary …
Risk Evaluation by COronary CTA and Artificial intelliGence Based fuNctIonal analyZing tEchniques - I
This study is a multicenter, retrospective imaging study. The study intends to retrospectively enroll patients with acute myocardial infarction who had received coronary CTA in a certain time-window before this event. All coronary CTA will be analyzed by anatomic, functional and radiomic analysis, assisted by artificial intelligence. The purpose of …
DK Nano-Culotte Stenting For Coronary Bifurcation Lesion
True coronary bifurcation lesions are still great of interest due to their complex anatomy, uncertainty of optimal stenting strategy and increased adverse cardiovascular outcomes. Provisional stenting is recommended in patients with non-complex coronary lesions while 2-stent strategies should be considered in complex coronary bifurcation lesions. However, optimal 2-stent strategy is …
Latvian Early Atherosclerosis Registry
Atherosclerosis and its complications are a global problem. There are several widely known and proven risk factors that promotes atherogenesis in the majority of patients. However, significant proportion of apparently healthy and young patients with cardiovascular disease but yet without recognized atherogenesis promoting risk factors can be observed in clinical …
Single-cell Multi-omics Analyses of OCT-diagnosed Plaque Subtypes in Coronary Artery Disease (MOOP-CAD)
The MOOP-CAD study program characterizes, for the first time, the pathophysiological processes and molecular mechanisms of coronary atherosclerotic plaque progression by combining in vivo intravascular imaging techniques with circulating immune single-cell multi-omics analysis. In this study, the investigators evaluate the imaging characteristics of coronary plaques by optical coherence tomography (OCT) …
Coronary Evaluation And Guided Lesion Exploration Using Photon-counting CT and Intracoronary Imaging Techniques
This study evaluates the diagnostic accuracy and limitations of photon-counting computed tomography (PCCT) in characterizing coronary plaque, with comparisons to optical coherence tomography (OCT) and intravascular ultrasound (IVUS). The objective is to assess whether cardiac ultra-high resolution (UHR) PCCT -with its improved spatial resolution and superior soft tissue contrast relative …
Relationship Between Coronary CT Angiography Findings and Prognosis Of Patients Undergoing PCI
Researchers at Cerrahpaşa Medical School in Istanbul are studying how a heart imaging test called coronary CT angiography can help improve care for people with coronary artery disease. This disease happens when fatty buildups, known as plaques, form in the arteries that supply blood to the heart. Over time, these …
