      Safety of optical coherence tomography in daily practice: a comparison with intravascular ultrasound

      Aims Previous studies have reported the safety and feasibility of both time-domain optical coherence tomography (TD-OCT) and Fourier-domain OCT (FD-OCT) in highly selected patients and clinical settings. However, the generalizability of these data is limited, and data in unselected patient populations reflecting a routine cathlab practice are lacking. We compared safety of intracoronary FD-OCT imaging to intravascular ultrasound (IVUS) imaging in a large real-world series of consecutive patients who underwent invasive imaging during coronary catheterization in our centre. Methods and results This is a prospective, single-centre registry of patients scheduled for coronary angiography or intervention undergoing intracoronary imaging with FD-OCT ...

      Vasa vasorum and coronary artery disease progression: optical coherence tomography findings

      Identification of predictors of coronary artery disease (CAD) genesis and progression has been an elusive target for many decades. Classical studies demonstrated that coronary angiography largely underestimates the severity and extent of CAD. 1 The characteristic diffuse involvement of the vessel wall by the atherosclerotic process together with the presence of remodelling phenomena explains why coronary angiography fails to detect early stages of CAD. 1 Notably, the advent of novel tomographic high-resolution intracoronary imaging techniques has been able to provide novel insights on the diagnosis of the initial stages of CAD. 1 , 2 Cardiac allograph vasculopathy (CAV) is considered an ...
