Abstract
This presentation is designed to provide insights on the application of conventional and advanced cardiac ultrasound concepts used in the assessment of myocardial deformation in congenital heart disease and palliative procedures. The presentation includes the maturation of myocardial mechanics, fiber orientation, contraction, relaxation, twist, torsion. An introduction to speckle tracking echocardiography-strain imaging including definitions and validation in the pediatric population will be discussed. The presentation will conclude with the clinical application of strain imaging in complex case examples including, tricuspid atresia, chemotherapy-induced cardio toxicity, graft rejection, and hypoplastic left heart syndrome.
Recommended presentation duration: 30-45 minutes.
Learning Objectives:
• Describe the basics of myocardial fiber architecture
• Explain the three principle vectors of myocardial deformation
• Explain basic concepts of speckle tracking echocardiography
• Interpret normal from abnormal strain waveforms
• Review cases commonly encountered in pediatric clinical practice
