Early changes in CT-derived quantitative flow ratio after transcatheter aortic valve replacement: a serial coronary physiological assessment
Transcatheter aortic valve replacement (TAVR) is an established treatment for severe aortic valve stenosis, but its effects on coronary physiology remain incompletely understood. CT-derived quantitative flow ratio (CT-QFR) enables non-invasive assessment of coronary physiology. This study aimed to investigate the e...
