Atrial fibrillation (AF) is common and its treatment is complex. The new European guidelines emphasize a patient-centered approach, considering the risk factors that contribute to AF and their management in primary and secondary prevention. Recent advances in electrophysiology include the development of new ablation techniques and the implantation of a leadless bicameral pacemaker.

Relaxometry and contrast-free cerebral microvascular quantification using balanced steady-state free precession MR fingerprinting.

Purpose: This study proposes a novel, contrast-free Magnetic Resonance Fingerprinting (MRF) method using balanced Steady-State Free Precession (bSSFP) sequences for the quantification of cerebral blood volume (CBV), vessel radius (R), and relaxometry parameters (T , T , T *) in the brain.

Methods: The technique leverages the sensitivity of bSSFP sequences to intra-voxel frequency distributions in both transient and steady-state regimes. A dictionary-matching process is employed, using simulations of realistic mouse microvascular networks to generate the MRF dictionary.

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.
