Nonetheless, a serious and relevant study is hidden behind that playful wink that might definitively designate optical coherence tomography (OCT) as the preferred tool for PCI guidance.

The inception of invasive computational physiology was outlined in 2014, in a shear stress study highlighting the importance ...
