| Sumario: | Calcific aortic valve disease (CAVD) is a progressive disorder where molecular alterations occur long before visible calcification, making early biomarkers essential. Extracellular vesicles (EVs) have gained attention as stable biomarkers due to their lipid bilayer, which protects proteins, lipids, and RNAs, ensuring reliable detection even in archived samples. This review highlights the role of EVs as biomarkers and delivery tools in CAVD. EVs derived from valvular endothelial, interstitial, and immune cells carry disease-specific signatures, including osteogenic proteins (BMP-2, Annexins), inflammatory miRNAs (miR-30b, miR-122-5p), and lipid mediators. These reflect early pathogenic processes before macroscopic calcification develops. Their presence in minimally invasive samples such as blood, urine, or saliva facilitates diagnosis, while their stability supports long-term monitoring of disease progression and therapeutic response. Advances in purification and single-EV analysis increase specificity, though challenges remain in standardizing methods and distinguishing CAVD-derived EVs from those in atherosclerosis. Beyond diagnostics, engineered EVs show promise as therapeutic carriers. Delivery of anti-calcific miRNAs or combined RNA cargos has reduced calcification and inflammation in preclinical models. Overall, EVs act as molecular mirrors of CAVD, enabling early diagnosis, risk stratification, and novel therapeutic strategies. Yet, clinical translation requires technical refinement and validation of the disease-specific signatures. |
