Combined analysis of coronary arteries and the left ventricular myocardium in cardiac CT angiography for detection of patients with functionally significant stenosis [PDF]

arXiv, 2019
Treatment of patients with obstructive coronary artery disease is guided by the functional significance of a coronary artery stenosis. Fractional flow reserve (FFR), measured during invasive coronary angiography (ICA), is considered the gold standard to define the functional significance of a coronary stenosis.

Rare coronary circulation anomaly causing chest pain: superdominant right coronary artery with absent left circumflex artery

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2019
Coronary circulation anomalies are the uncommon cause of chest pain when hemodynamically significant. Multidetector computed tomography (CT) of coronary arteries is rapidly replacing conventional angiography, nowadays, as the first line of investigation ...

Multi-modality imaging of a left atrial myxoma

SAGE Open Medical Case Reports, 2017
Objectives: Although echocardiography has traditionally been used to diagnose myxoma, invasive or non-invasive coronary angiography can be useful diagnostic tool before surgery.

Single coronary artery from right aortic sinus in a very elderly patient

Journal of the Saudi Heart Association, 2016
In the absence of other associated cardiac anomalies, single coronary artery (SCA) per se is a rare anomaly detected during coronary angiography or autopsy. Various types of SCA detected during coronary angiography have already been described.

Deep Neural Networks for ECG-free Cardiac Phase and End-Diastolic Frame Detection on Coronary Angiographies [PDF]

arXiv, 2018
Invasive coronary angiography (ICA) is the gold standard in Coronary Artery Disease (CAD) imaging. Detection of the end-diastolic frame (EDF) and, in general, cardiac phase detection on each temporal frame of a coronary angiography acquisition is of significant importance for the anatomical and non-invasive functional assessment of CAD.

Evaluation of computed tomography in patients with atypical angina or chest pain clinically referred for invasive coronary angiography: randomised controlled trial

British medical journal, 2016
Objective To evaluate whether invasive coronary angiography or computed tomography (CT) should be performed in patients clinically referred for coronary angiography with an intermediate probability of coronary artery disease.

Automated Characterization of Stenosis in Invasive Coronary Angiography Images with Convolutional Neural Networks [PDF]

arXiv, 2018
The determination of a coronary stenosis and its severity in current clinical workflow is typically accomplished manually via physician visual assessment (PVA) during invasive coronary angiography. While PVA has shown large inter-rater variability, the more reliable and accurate alternative of Quantitative Coronary Angiography (QCA) is challenging to ...

Trends and Outcomes of Coronary Angiography and Percutaneous Coronary Intervention After Out-of-Hospital Cardiac Arrest Associated With Ventricular Fibrillation or Pulseless Ventricular Tachycardia.

JAMA cardiology, 2016
Importance The 2015 cardiopulmonary resuscitation and emergency cardiovascular care guidelines recommend performing coronary angiography in resuscitated patients after cardiac arrest with or without ST-segment elevation (STE).

Referral to coronary angiography post myocardial perfusion imaging

Journal of the Saudi Heart Association, 2018
Introduction: The current guidelines for CAD suggest that patients with moderate to severe ischemia should be referred for angiography and possible revascularization, while patients with mild ischemia can be safely treated medically.
