Optical Coherence Tomography in the Assessment and Management of Cardiac Allograft Vasculopathy

Arka Chatterjee et al. Curr Cardiol Rep. 2024 Aug.

Abstract

Purpose of review: Cardiac Allograft vasculopathy (CAV) is a major barrier to improving outcomes after heart transplantation. Coronary angiography has very low sensitivity to detect early CAV and intravascular ultrasound (IVUS) only improves it to some extent. In this article, we detail the current evidence surrounding use of Optical Coherence tomography (OCT) in patients with CAV.

Recent findings: OCT has the ability to recognize CAV at earlier stages with intimal thickness < 150 μm, can characterize CAV in almost pathologic / microscopic detail - plaque characteristics are better visualized and novel early features such as layered fibrotic plaques and microchannels have been identified. Progression of CAV can be monitored also, with promise shown in automated serial measurements also. OCT has significantly advanced our understanding of the pathophysiology-as well as permits precise monitoring and surveillance of the disease. Potential treatment options could also be evaluated using OCT.

Keywords: Cardiac allograft vasculopathy; Optical coherence tomography.
