Surgery for Aneurysmal Coronary Artery Fistulas to the Coronary Sinus in Adults

JACC: Case Reports, 2022
Surgical treatment of aneurysmal distal congenital coronary artery fistulas depends on size and anatomy. From 2008 to 2021, we applied a new surgical technique in 7 adult patients: proximal and distal fistula closure, opening of aneurysmal artery, and ...

Graph Convolutional Networks for Coronary Artery Segmentation in Cardiac CT Angiography [PDF]

arXiv, 2019
Detection of coronary artery stenosis in coronary CT angiography (CCTA) requires highly personalized surface meshes enclosing the coronary lumen. In this work, we propose to use graph convolutional networks (GCNs) to predict the spatial location of vertices in a tubular surface mesh that segments the coronary artery lumen.

Left ventricular dysfunction: Neither a matter of atherosclerosis nor an anomalous originated right coronary artery from left anterior descending artery

ARYA Atherosclerosis, 2015
BACKGROUND: Abnormal separation of right coronary artery (RCA) from the left coronary system is an extremely rare variation among coronary artery anomalies.

Annotation-Free Cardiac Vessel Segmentation via Knowledge Transfer from Retinal Images [PDF]

arXiv, 2019
Segmenting coronary arteries is challenging, as classic unsupervised methods fail to produce satisfactory results and modern supervised learning (deep learning) requires manual annotation which is often time-consuming and can some time be infeasible. To solve this problem, we propose a knowledge transfer based shape-consistent generative adversarial ...

STEMI With a Massive Coronary Aneurysm

JACC: Case Reports, 2020
An 83-year-old man with significant background comorbidities was admitted with an inferior ST-segment elevation myocardial infarction. During primary percutaneous coronary intervention, a giant aneurysm is seen in the right coronary artery.

Right Anomalous Coronary Artery Origin: The Role of Multislice CT Angiography

Majalah Kardiologi Indonesia, 2016
Introduction: The anomalous origin of the right coronary artery (RCA) from the left coronary sinus coursing between the aorta and the pulmonary trunk is rare, but may cause myocardial ischemia and sudden death.

Coronary Artery Fistula Involving the RCA, LAD, and the Main Pulmonary Artery

JACC: Case Reports
We present a case of a complex congenital coronary artery fistula between the right coronary artery, left anterior descending artery, and the main pulmonary artery complicated by massive aneurysms and a left-to-right shunt. We highlight the multimodality

Coronary Artery Fistula

JACC: Case Reports, 2020
Coronary artery fistula (CAF) is an abnormal connection between a coronary artery and a heart chamber resulting in left-to-right shunt. A large CAF was an unexpected cause of heart failure in a 58-year-old woman who underwent transcatheter closure of the

“A curious case of “Cache” coronary: Case report”

IHJ Cardiovascular Case Reports, 2022
Coronary artery anomalies are estimated to be present in 1.8% of the population. Though majority of them are benign, some may lead to angina pectoris, myocardial infarction, cardiac arrhythmias, congestive heart failure and sudden cardiac death ...

Complex Ebstein's Anomaly in an 86-Year-Old Iranian Man: A Case Report

Journal of Tehran University Heart Center, 2017
Ebstein's anomaly is defined as the significant apical displacement of the tricuspid valve causing tricuspid regurgitation. Although a variety of concomitant lesions have been previously described, we herein introduce an unusual presentation.
