The anomalous aortic origin of a coronary artery is a rare congenital condition characterized by deviations in the origin, course, or size of coronary arteries. Among these, the anomalous aortic origin of the right coronary artery is a less common variant, particularly when originating from the ascending aorta above the sinotubular junction.

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.

Background: Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (PA) (ALCAPA) is a rare congenital abnormality. We present a case of an ALCAPA in a 25-year-old man.
Case Summary: A 25-year-old male with no past medical history was admitted to our intensive cardiac care unit after sudden cardiac arrest due to ventricular fibrillation and suspected acute coronary syndrome.

Control of crack propagation is crucial to make tougher heterogeneous materials. As a crack interacts with material heterogeneities, its front distorts and adopts complex tortuous configurations. While the behavior of smooth cracks with straight fronts in homogeneous materials is well understood, the toughening by rough cracks with tortuous fronts in heterogeneous materials remains unsolved.

Article Synopsis
- Cardiac MRI is the best method for detecting and assessing heart muscle conditions, with late gadolinium enhancement helping in patient classification and management.
- Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect that can show myocardial enhancement on MRI.
- This report discusses unusual mid myocardial late gadolinium enhancement found in three adult patients with ALCAPA, differing from typical enhancement patterns.
