StenUNet: Automatic Stenosis Detection from X-ray Coronary Angiography [PDF]
arXiv, 2023 Coronary angiography continues to serve as the primary method for diagnosing coronary artery disease (CAD), which is the leading global cause of mortality. The severity of CAD is quantified by the location, degree of narrowing (stenosis), and number of arteries involved.

Unusual case of single coronary artery with anomalous RCA from LAD: The ultimate of cardiac CT
IHJ Cardiovascular Case Reports, 2021 Coronary artery anomalies are found in 0.6%–1.55% of patients who undergo coronary angiography, and the increasing use of diagnostic coronary angiography is unveiling even more complex coronary anomalies.

Reducing the X-ray radiation exposure frequency in cardio-angiography via deep-learning based video interpolation [PDF]
arXiv, 2020 Cardiac coronary angiography is a major technology to assist doctors during cardiac interventional surgeries. Under the exposure of X-ray radiation, doctors inject contrast agents through catheters to determine the position and status of coronary vessels in real time.

Case Reports in Cardiology, 2020 Coronary artery aneurysm (CAA) is a rare cardiac anomaly with a reported incidence of 0.3-4.9% of patients who undergo coronary angiography. The term is used when the coronary artery diameter exceeds more than 50% or 1.5 times the reference diameter.

Disarranged Zone Learning (DZL): An unsupervised and dynamic automatic stenosis recognition methodology based on coronary angiography [PDF]
arXiv, 2021 We proposed a novel unsupervised methodology named Disarranged Zone Learning (DZL) to automatically recognize stenosis in coronary angiography. The methodology firstly disarranges the frames in a video, secondly it generates an effective zone and lastly trains an encoder-decoder GRU model to learn the capability to recover disarranged frames.
