To evaluate image quality, coronary interpretability and radiation exposure of coronary CT angiography (CCTA) performed in patients with atrial fibrillation (AF) with the latest scanner generation, comparing two different technical approaches.

A new scanner that combines a 0.23 mm spatial resolution, a new generation of iterative reconstruction, fast gantry rotation time and the intracycle motion-correction algorithm to improve the temporal resolution was recently introduced in the clinical field.

While the two VICs types did not differ for basic responses onto substrates with different stiffness values (e.g. adhesion and proliferation), they were subject to a different dynamics of stiffness-dependent YAP nuclear shuttling, revealing for the first time an intracellular force transduction mechanism distinctive for calcific aortic valve disease.
