Value of cardiovascular magnetic resonance-derived quantitative myocardial blood flow assessment in the setting of chronic coronary occlusion.

ABSTRACT:

Aims

For many years, visual assessment has been the mainstay of detecting obstructive coronary artery disease (CAD) by stress perfusion cardiovascular magnetic resonance (S-CMR). Recently, fully automated quantitative assessment of myocardial blood flow (MBF) has been introduced. The value of MBF quantification in patients with coronary chronic total occlusion (CTO) is unknown. In this study, we sought to investigate the diagnostic performance of CMR-derived fully automated quantitative MBF assessment in patients with CTO.

Methods and results

Consecutive patients who underwent S-CMR, as well as coronary angiography at our institution between February 2023 and November 2024 were included. S-CMR perfusion imaging was evaluated visually and quantitatively. Stenosis severity was
