Scientific Abstracts - Pediatric and Congenital Heart Disease Scientific Presentations-Discussion

Video Transcription

Video Summary

The transcript captures a Q&A session following several cardiovascular imaging presentations. Dr. Schober described a noninvasive method for quantifying pressure-volume loops in congenital heart disease using a short-axis stack, brachial pressure, and a double-hill equation, noting limitations in estimating ventricular pressure in aortic stenosis and earlier issues with contractility at high heart rates. Dr. Johnson explained 4D flow scanning in aortic stenosis, including how velocity ranges are set and how aliasing is managed, with future interest in valve morphology. Dr. Luck discussed RV energy loss and vorticity analysis in repaired tetralogy of Fallot, emphasizing static diastolic masking and limitations in tracking dynamic RVOT changes. Dr. Lee addressed uncertain strain abnormalities in young athletes after COVID, stressing the need for athlete controls and longitudinal follow-up. Dr. Maffaro highlighted lateral myocardial abnormalities in Duchenne muscular dystrophy and the value of 3T MRI. Dr. Hutt discussed reproducibility of a fetal/heart-rate extraction technique and challenges in fetal applications.
