Isovolumic relaxation time and e' metrics evaluated by deep-learning analysis of long-axis cine: correlations to atrial pressure and fibrosis

Isovolumic relaxation time and e' metrics evaluated by deep-learning analysis of long-axis cine: correlations to atrial pressure and fibrosis

Using a deep-learning tool for tracking the left ventricular valve plane on long-axis cine, markers of diastolic dysfunction could be easily evaluated, including e-prime, a-prime (atrial kick valve velocity), s-prime, and isovolumic relaxation time (IVRT). This analysis, performed in 23 patients wit...
