Alkaptonuric aortic stenosis [PDF]
European Heart Journal, 2007 A 71-year-old male patient was referred for the evaluation of a high-grade aortic stenosis. His medical history revealed prosthetic hip and joint replacement due to degenerative arthritis at the age of 55. On physical examination, a 2/4 systolic ejection murmur at the right upper sternal border, kyphosis, and a bluish-black discolouration of the sclera

Advanced Science, EarlyView.CD72hi macrophages drive endothelial pyroptosis and accelerate atherosclerosis through CXCL12–CXCR4‐mediated immune–vascular crosstalk. Ilexoside K suppresses this pathogenic communication by modulating CXCR4‐dependent endothelial responses, reducing inflammation and plaque progression. These findings reveal a macrophage–endothelial regulatory axis and

Left Main Coronary Ostial Stenosis after Aortic Valve Replacement: A Case Report
, 2016 Coronary ostial stenosis is a rare but potentially life-threatening complication of aortic valve replacement (AVR). It can present potential complications such as acute coronary syndrome, left ventricular failure, ventricular arrhythmias, or sudden death.

Advanced Science, EarlyView.Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.

Advanced Science, EarlyView.Postoperative arteriovenous fistulas exhibit increased RBMS1 in vascular smooth muscle cells (VSMCs). In experimental AVFs, RBMS1 overexpression aggravates, whereas deletion attenuates, neointimal hyperplasia. RBMS1 binds MPZL1 mRNA and promotes exon 5 skipping to generate MPZL1‐Δ5, which interacts with G3BP1 to activate AKT, driving VSMC proliferation,
