Fluid Responsiveness and Venous Congestion Evolution During Volume Expansion
Fluid responsiveness is a critical determinant guiding fluid therapy in critically ill patients. However, excessive fluid administration can result in fluid overload, leading to venous congestion and worse clinical outcomes. Venous congestion, a marker of impaired fluid clearance, is increasingly recognized as a significant contributor to poor prognosis. Previous studies …
Arch Size Study for Anatomical Variations
The aortic arch with a common origin of the innominate and left carotid artery (CILCA) prevalence in the general population is 13.6%. Its reputation as a benign anatomical variant has been ultimately shattered by further studies that identified the CILCA arch as a potential marker for thoracic aortic disease (TAD) …
Longitudinal Study for Central Nervous System Vasculitis
Primary central nervous system vasculitis (CNSV) is a potentially fatal, single-organ vasculitis that often involves a spectrum of neurologic complications, including strokes, cognitive and speech impairment, visual loss, dementia, and encephalopathy. The purpose of this study is to establish a research cohort to investigate the disease process, treatments, and patient …
OCT in Rare Chorioretinal Diseases
This study will evaluate the total blood flow in the retina and choroid (structures in the back of the eye) by Doppler optical coherence tomography (OCT) and OCT angiography. Angiography is mapping of the blood vessels. The purpose of measuring blood flow in the retina and choroid is to 1.) …
Correlating Multispectral Near-Infrared Imaging to Standard Vascular Diagnostics
The goal of this observational study is to learn if the measures of tissue oxygenation from the MIMOSA Pro imaging device correlate to standard vascular assessment tools in patients who receiving a lower extremity vascular assessment. The main questions it aims to answer are: Do the MIMOSA Pro tissue oxygenation …
CILCA Arch Registry: Management and Outcomes of Open and Endovascular Repair
This registry aims to provide insights on the pathogenic mechanisms that expose subjects with CILCA arch to the increased risk of postoperative complications. So, the CILCA arch registry will capture clinical data and medical images of subjects with CILCA arch treated by surgical or endovascular (TEVAR) means. Study Design: International …
A Study of Pressure Waveform Analysis in Coronary Artery-II
The goal of this observational study is to test the feasibility of intracoronary adenosine administration during coronary flow reserve(CFR) and index of microcirculatory resistance(IMR) assessment in a population with angina. The main questions it aims to answer are Repeatability of CFR and IMR assessment while hyperemia with intracoronary adenosine was …
A Clinical Study of Evaluating Myocardial Viability in Ischemic Heart Disease with Integrated 18F-FDG PET/MR
The main purpose is to evaluate the accuracy of myocardial imaging obtained through integrated 18F-FDG PET/MR in detecting viable myocardium. The secondary objective is to evaluate whether myocardial imaging obtained through integrated 18F-FDG PET/MR can replace 18F-FDG PET combined with 99mTc MIBI SPECT/CT gated myocardial perfusion imaging.
Pulmonary Hypertension in Left Heart Disease
The goal is to compare patients with and without varying severity of pulmonary vascular disease based upon hemodynamic signatures, echocardiographic measures, and lung ultrasound, in tandem with expired gas metabolic testing and blood sampling.
International Multicenter Mycotic Aneurysm Aorto-iliac Study
The term mycotic aneurysm (MA) is commonly used to describe all infected aneurysms. Although MAs are believed to occur uncommonly, the true incidence is difficult to determine and is probably underestimated since MAs can be asymptomatic and are diagnosed only at autopsy. In an autoptic study, mycotic aortic aneurysms (MAAs) …
