A Case of 3: Coronary Artery Calcification Masquerading as a Stent on Chest X-ray

Indian Journal of Clinical Cardiology, 2023
Coronary artery calcification in patients with coronary artery disease is associated with increased major adverse cardiovascular events. They are usually diagnosed on a computed tomography scan or on an invasive coronary angiography.

Myocardial Perfusion Imaging Versus Computed Tomography Angiography–Derived Fractional Flow Reserve Testing in Stable Patients With Intermediate‐Range Coronary Lesions: Influence on Downstream Diagnostic Workflows and Invasive Angiography Findings

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundData on the clinical utility of coronary computed tomography angiography–derived fractional flow reserve (FFRCT) are sparse. In patients with intermediate (40–70%) coronary stenosis determined by coronary computed tomography angiography, we ...

The challenge to detect heart transplant rejection and transplant vasculopathy non-invasively - a pilot study [PDF]

, 2009
Background Cardiac allograft rejection and vasculopathy are the main factors limiting long-term survival after heart transplantation. In this pilot study we investigated whether non-invasive methods are beneficial to detect cardiac allograft rejection ...

Computed Tomography Coronary Angiography

Journal of the American College of Cardiology, 2006
Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging.

Coronary CT Angiography and 5-Year Risk of Myocardial Infarction. [PDF]

, 2018
BACKGROUND: Although coronary computed tomographic angiography (CTA) improves diagnostic certainty in the assessment of patients with stable chest pain, its effect on 5-year clinical outcomes is unknown.

Prognostic durability of coronary computed tomography angiography

European Heart Journal - Cardiovascular Imaging, 2020
Abstract Aims  This large prospective cohort study sought to confirm the incremental prognostic value of coronary computed tomographic angiography (CCTA) measured over a prolonged follow-up duration. CCTA has diagnostic and prognostic value but data supporting its long-term prognostic value in a large
