Physicians Pre-Conference: Cardiac Function-Assessment of diastolic function

Video Transcription

Video Summary

Dr. Jonathan Weintraub discusses how cardiac MRI can assess diastolic dysfunction, a condition caused by decreased left ventricular compliance and increased filling pressures that leads to dyspnea and heart failure. He reviews the limitations of echocardiography and highlights CMR’s strengths: high spatial resolution, 3D assessment, and tissue characterization. Methods covered include phase-velocity imaging, 4D flow, tagging, routine cine-based strain analysis, left atrial strain, late gadolinium enhancement, and T1 mapping/extracellular volume. Across studies, CMR correlates with echo, invasive pressures, symptoms, and prognosis, suggesting it may better reveal mechanisms and severity of diastolic dysfunction.
