A previously undescribed complex coronary artery anomaly
Heart Views, 2013 Coronary artery anomalies are uncommon disorders. According to the literature, ≈1% of the general population is affected by a coronary artery abnormality. Coronary artery anomalies are often not associated with clinical signs, symptoms, or complications;

Partial Vessels Annotation-based Coronary Artery Segmentation with Self-training and Prototype Learning [PDF]
arXiv, 2023 Coronary artery segmentation on coronary-computed tomography angiography (CCTA) images is crucial for clinical use. Due to the expertise-required and labor-intensive annotation process, there is a growing demand for the relevant label-efficient learning algorithms.

Intercoronary fistula: Rarest of rare coronary anomaly
Journal of the Practice of Cardiovascular Sciences, 2019 Coronary artery fistulas are rare but fascinating anomalies. It is defined as an abnormal direct vascular connection from coronary artery to a cardiac chamber or major central blood vessel without an intervening capillary bed. Among all coronary fistulas,

Heart Dominated by Solitary Coronary: A Case Report
European Journal of Medical and Health Sciences, 2023 The prevalence of coronary artery anomalies has been detected in 0.6% to 1.5% of coronary angiography. They are found since birth but usually with no significant symptoms and it does not generally manifest as myocardial ischemia however, malignant ...

Robust PCA Unrolling Network for Super-resolution Vessel Extraction in X-ray Coronary Angiography [PDF]
arXiv, 2022 Although robust PCA has been increasingly adopted to extract vessels from X-ray coronary angiography (XCA) images, challenging problems such as inefficient vessel-sparsity modelling, noisy and dynamic background artefacts, and high computational cost still remain unsolved.

Extraction of Coronary Vessels in Fluoroscopic X-Ray Sequences Using Vessel Correspondence Optimization [PDF]
, 2022 We present a method to extract coronary vessels from fluoroscopic x-ray sequences. Given the vessel structure for the source frame, vessel correspondence candidates in the subsequent frame are generated by a novel hierarchical search scheme to overcome the aperture problem.
