As leaders in the industry, the CTC staff will work with you to define and fulfill the ECG and rhythm analysis needs for your study.
An increasing number of heart failure studies involve the collection and interpretation of hemodynamic data. Clinically used hemodynamic recording systems (in a cath lab or intensive care unit) generally include software that provides automated readings of all common hemodynamic parameters. While physicians generally rely on these readings for clinical decision making, these algorithms lack certain sophistication required for detailed analyses as required in the context of clinical trials. Furthermore, different recording systems employ different algorithms for quantifying recordings. This is particularly the case when hemodynamics are being recording during exercise, which is being included in a growing number of studies. To overcome these limitations and to overcome the potential for introduction of investigator bias a Hemodynamic Core Lab is recommended to ensure consistent, systematic collection and interpretation of data.
Specific services include:
- Generation of study-specific SOPs for performance of hemodynamic measurements including:
- Equipment setup
- Site training on the SOPs and validation
- Development of study-specific worksheet for use by the sites during testing
- Logging and tracking of tests received
- Rapid feedback on test quality
- Provide retraining if necessary
- Blinded interpretation of study results
- Study-specific hemodynamic results database
- Statistical analysis of study results, expert interpretation of findings and report generation

Non-Invasive Imaging (CT, MRI)
The Cardiac Computed Tomography Angiography (CCTA) Core Lab performs comprehensive qualitative and quantitative analyses on cardiovascular computed tomographic angiograms. The CCTA Core Lab provides coronary artery analysis for volumetric quantification and characterization of atherosclerotic plaque and vessel measures; cardiac analysis for quantitation of myocardial function and perfusion; valvular function and measurements; and other vascular evaluations.
State-of-the-art advances in imaging technology now permit non-invasive evaluation of coronary, cardiac, and vascular findings with very high accuracy compared to invasive imaging. The CCTA Core Lab also provides assistance with developing CCTA protocols, image-acquisition methods, site qualification, image feedback and training.
The Cardiac Magnetic Resonance Imaging (MRI) Core Lab assesses global and regional systolic ventricular function, myocardial perfusion and viability, and valvular heart disease. Recent advances in the field have dramatically improved the quality of cardiac MRI images by providing:
- Excellent spatial and temporal resolution
- Higher precision and reproducibility
- Adequate sensitivity to detect smaller areas of myocardial damage with an accuracy surpassing other forms of testing, allowing trials to reach statistical significance with fewer patients.

The Cardiovascular Physiology Core Lab at the Cardiovascular Research Foundation provides researchers, clinicians, and clinical trial sponsors with state-of-the-art centralized analysis of cardiac and coronary physiology data. Coronary physiology measurements are increasingly used clinically as adjunctive tools during diagnostic and interventional coronary procedures. As the body of research expands, further establishing the value of these modalities, quality control of future clinical studies will become increasingly important. Accordingly, the mission of the Cardiovascular Physiology Core Lab is to provide a novel service of ensuring data quality for clinical research trials, which heretofore has not been standard practice in coronary physiology studies.
Services are tailored to the investigator’s needs and focus on providing data suitable for use in future studies, FDA submissions, and scientific manuscripts.
