Catheterization Techniques for Anomalous Aortic Origin of Coronary Arteries.
Catheter Cardiovasc Interv
January 2025
Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital anomaly with a large spectrum of anatomical variations. Selective engagement of an AAOCA can present challenges during cardiac catheterization. A comprehensive understanding of the characteristics of major AAOCA can effectively assist operators for selecting and maneuvering catheters.

- The study examines the occurrence and location of coronary artery disease (CAD) in adults with anomalous aortic origin of a coronary artery (AAOCA), which is not well documented.
- Researchers analyzed data from 390 patients, focusing on the presence of CAD through imaging techniques like coronary angiography.
- The findings revealed that CAD is more prevalent in the proximal segment of retroaortic AAOCA compared to other types of AAOCA, with no CAD found in the proximal segment of interarterial AAOCA, and the reasons for these differences remain unclear.
Anomalous aortic origin of the coronary arteries are congenital anomalies with many anatomical forms. Due to the varying risk of sudden death, these abnormalities must be classified accurately. There are still questions about the mechanism and individual risk of sudden death, the natural history of these abnormalities and the benefits of a surgical correction.

- * Despite its prevalence, vasospastic angina is often underdiagnosed, and specific tests to identify it are not frequently conducted due to inconsistent protocols.
- * The French Coronary Atheroma and Interventional Cardiology Group (GACI) released a position paper focusing on the criteria and protocols for conducting provocative tests to better diagnose and understand vasospastic angina.
Article Synopsis
- The CAMCATT-AI4GEO field experiment took place in Toulouse, France, from June 14 to June 25, 2021, aiming to create a reference dataset for validating future thermal infrared satellite missions.
- This dataset will help assess urban climate factors like land surface temperature, air temperature, and the Urban Heat Island effect at a neighborhood scale using advanced satellite data with high spatial and temporal resolution.
- The campaign collected a variety of data types including airborne hyperspectral and thermal imaging, 3D LiDAR, and ground measurements from multiple instruments, providing a comprehensive overview of the city's thermal and spectral characteristics.
