Anomalous origin of the left coronary artery from pulmonary artery mimicking antero-lateral ST-elevation myocardial infarction: a case report.
Eur Heart J Case Rep
January 2025
Cardiology Department, Meir Medical Center, Tchernichovsky St 59, Kfar Saba 4418001, Israel.
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.
Distorting crack-front geometry for enhanced toughness by manipulating bioinspired heterogeneity.
Nat Commun
January 2025
CAS Key Laboratory of Mechanical Behavior and Design of Materials, Department of Modern Mechanics, CAS Center for Excellence in Complex System Mechanics, University of Science and Technology of China, Hefei, Anhui, China.
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.

February 2025
From the Department of Radiology, Narayana Institute of Cardiac Sciences, Bangalore 560099, India (S.G., V.R.); and Department of Radiology, Amrita Institute of Medical Sciences and Research Centre, Kochi, India (R.R.).
Cardiac MRI is the reference standard for identifying and evaluating myocardial pathologic conditions. Late gadolinium enhancement characteristics provide an excellent guide in classifying disease and triaging patients. Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is an uncommon congenital anomaly.

Clin Imaging
December 2024
Mersin University, Faculty of Medicine, Department of Anatomy, Mersin, Turkey.
Purpose: It has been demonstrated that the coronary artery anomalies (CAAs) are generally asymptomatic. However, some cases can cause severe life threatening events. As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative to invasive coronary angiography for the evaluation of coronary anatomy, the prevalence of CAAs in CCTA may more closely reflect the true prevalence in the general population.

Discoveries (Craiova)
March 2024
Interventional Cardiologist, Apollo Hospitals Chennai Greams Road, India.
This case report examines a rare cardiovascular abnormality, the Aberrant Aortic Origin of the Right Coronary Artery (AAORCA), in a 75-year-old patient with a history of myocardial infarction, acute renal injury, and cardiogenic shock. Rapid medical intervention, including coronary angioplasty, demonstrated the significance of prompt care. Chronic issues, including tobacco use and left ventricular dysfunction, complicated matters, emphasizing the importance of comprehensive long- term therapy.
