A CCTA with FFR measurements refers to a coronary computed tomography angiography (CCTA) scan where the imaging data is analyzed to calculate a fractional flow reserve (FFR) value, essentially providing a non-invasive assessment of how well blood flows through coronary arteries, while a cath report with FFR measurements is a report from a cardiac catheterization procedure where FFR is directly measured using a catheter inserted into the coronary arteries.
Overview
A CCTA with FFR measurements refers to a coronary computed tomography angiography (CCTA) scan where the imaging data is analyzed to calculate a fractional flow reserve (FFR) value, essentially providing a non-invasive assessment of how well blood flows through coronary arteries, while a cath report with FFR measurements is a report from a cardiac catheterization procedure where FFR is directly measured using a catheter inserted into the coronary arteries, providing a more invasive but potentially more precise assessment of coronary artery stenosis severity. An instantaneous wave-free ratio (iFR) measurement is a physiological index that assesses the severity of coronary stenosis. It's a non-hyperaemic pressure index that measures the ratio of distal coronary pressure to aortic pressure during diastole. A cardiac intravascular ultrasound (IVUS) is a diagnostic procedure that uses sound waves to create images of the heart's blood vessels. It's a type of cardiac catheterization that can help diagnose and treat heart conditions.
Datasets include: Cardiac CT Angiography (CCTA) studies that provide a comprehensive evaluation of coronary artery stenosis, including detailed information on stenosis grade and location, with additional CT-based fractional flow reserve (FFR) measurements to assess the physiological significance of blockages. Major CT vendors such as GE, Toshiba, Philips, and Siemens provide high-resolution imaging for accurate coronary assessments. In cases of further intervention, follow-up reports include catheterization results, with intravascular FFR/IFR measurements, intravascular ultrasound (IVUS), and balloon angioplasty outcomes to evaluate treatment efficacy and vessel patency.

Pricing
This product is available free of charge. Free subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimensions summary
This listing offers one pricing dimension: Product Access, measured in Units. It is a free subscription that grants you access to the de-identified medical imaging dataset. There are no paid tiers, instance sizes, or usage add-ons to choose from. You subscribe under a single access option. The dataset is a sample of cardiac CT angiography real-world data, delivered through a one-month subscription. Because pricing is free, the Units dimension simply controls your access rather than scaling cost with consumption.
Top-of-mind questions for buyers
One unit grants you access to the de-identified cardiac CT angiography sample dataset. Because the listing is free, the unit controls entry to the data rather than scaling any cost. You subscribe for a one-month period to explore the imaging cohort.
The published datasets are offered as free one-month subscriptions to sample the data. This listing is a sample cohort, not a continuous feed. To pursue ongoing, longitudinal data access or curated cohorts beyond the sample, contact the vendor to discuss your requirements.
No. This dimension is billed as free, so accessing the dataset does not accrue software charges based on volume or usage. The unit simply enables access. You are not metered on how much of the imaging data you view or download during the subscription.

The International Cardiac Arrest REsearch consortium (I-CARE) Database includes baseline clinical information and continuous electroencephalography (EEG) recordings from 1,020 comatose patients with a diagnosis of cardiac arrest who were admitted to an intensive care unit from seven academic hospitals in the U.S. and Europe. Patients were monitored with 18 bipolar EEG channels over hours to days for the diagnosis of seizures and for neurological prognostication. Long-term neurological function was determined using the Cerebral Performance Category scale.
