Article Abstract
A 76-year-old woman presented with anterolateral ST-segment elevation myocardial infarction complicated by incessant ventricular arrhythmia. Angiography did not find obstructive coronary disease. Echocardiography demonstrated "double valve sign," pathognomonic of aortic dissection, which was subsequently confirmed on computed tomography. The coronary arteries arose from the true lumen; thus, it was understood that her presentation was caused by external coronary ostia compression by the growing false aortic lumen. It has long been understood that when aortic dissection involves the coronary arteries, it typically affects the right artery. This case highlights a rare complication of aortic dissection affecting the left coronary artery.

Background: An inward force is experienced by the guide catheter during device retrieval resulting in potential risk of deep engagement into the ostio-proximal coronary segment. This undesired movement can result in coronary injury. There is no systematic data or reports of techniques to prevent such inadvertent guide movement during difficult retrieval of devices.

Nickel exposure elevates aortic dissection (AD) risk, yet its pathogenic mechanisms remain unclear. Here, we demonstrate that nickel accelerates AD progression, particularly in hypertensive individuals. Bioinformatics analysis of GEO datasets identified chemokine-mediated endothelial-neutrophil crosstalk as a key pathway.
