Cardiac computed tomography (CT), and in particular computed tomographic coronary angiography (CTCA), stand poised to revolutionize the way in which cardiac pathology is diagnosed, and change the way in which decisions are made with regards to invasive treatment of cardiac disease. In particular, the diagnosis of coronary disease (the number one killer of patients in modern societies) will be… View more

The highlights of the last decade in interventional cardiology have been the introduction of drug-eluting stents and an overall simplification of percutaneous coronary interventional procedures from a technological standpoint. Indeed, most interventions currently consist of either direct stenting or pre-dilatation followed by stent implantation; the use of rotational atherectomy and other niche… View more

Acute kidney injury (AKI) is a frequent occurrence in hospitalized patients and its overall incidence appears to be increasing. In addition, the number of patients in whom AKI is preceded by exposure to iodinated contrast is also increasing (see Figure 1). Patients who develop AKI in hospital are typically those undergoing major surgical procedures and individuals suffering from hemodynamic… View more

Cardiovascular disease (CVD) afflicts greater than 70 million patients in the US alone, and accounts for over half of all deaths. Non-invasive cardiac imaging modalities are used to provide enhanced methods of diagnosis of CVD, guidance of patient-specific therapy, and prognostication of cardiac-related risk. Non-invasive cardiovascular imaging has traditionally been stratified into two distinct… View more

The cost and the risk of invasive angiography have encouraged the development of new diagnostic methods that allow the coronary arteries to be visualized non-invasively. The last decade has seen great strides in the field of cardiac imaging, particularly in the ability of cardiac computed tomographic angiography (CTA) to visualize the coronary lumen with excellent diagnostic accuracy (see Table 1… View more

Overview of Quantitative Flow Ratio and Optical Flow Ratio in the Assessment of Intermediate Coronary Lesions
Author(s): Jelmer Westra , Shengxian Tu Added: 3 years ago
Physiological lesion assessment is recommended for the identification of intermediate coronary lesions that might benefit from percutaneous coronary intervention (PCI).1 The quantitative flow ratio (QFR) was developed to derive coronary physiology from angiographic images, whereas the optical flow ratio (OFR) is a more recent approach for the rapid and automated assessment of coronary physiology… View more
