An increasing number of procedures over the past two decades for aortic stenosis (AS) reflects the combination of an aging population and less invasive transcatheter options. As a result, the hemodynamics of the aortic valve (AV) have gained renewed interest to understand its behavior and to optimize patient selection. We studied the hemodynamic relationship between pressure loss (ΔP) and transvalvular flow (Q) of the normal AV as well as the impact of a variable supravalvular stenosis.

The year 2024 has witnessed substantial advancements in interventional cardiology, encompassing both coronary and structural interventions.In coronary field, trials have explored percutaneous innovations for coronary lesions, strategies for managing post‑infarction cardiogenic shock and non‑invasive approaches for guiding revascularization. The uploaded guidelines for chronic coronary syndromes emphasize individualized care, integrating modalities such as fractional flow reserve (FFR), intravascular ultrasound (IVUS), optical coherence tomography (OCT) and new teatments, including cochicine, GLP-1 receptor agonists and bempedoic acid.

Aims: Less pronounced calcification of the aortic valve (AVC) was observed in women with aortic stenosis (AS) as compared to men. Since women have smaller aortic valves (AV), this could explain a lower calcium load. We aimed to analyze the association of AV size with AVC independent from sex.
