Prognostic implications of cardiac magnetic resonance feature tracking derived multidirectional strain in patients with chronic aortic regurgitation

ConclusionsCMR-FT myocardial deformation parameters are impaired in patients with AR not meeting surgical criteria. GLS decreases early in the course of the disease and is a marker of AR severity while GCS and GRS worsen later but predict a bad prognosis, mainly the need of aortic valve surgery.Key Points• CMR feature tracking LV mechanic parameters may be reduced in significant chronic AR with normal EF.• LV mechanics, mainly global longitudinal strain, worsens as AR severity increases.• LV mechanics, specially global radial and circumferential strain, is associated with a worse prognosis in AR patients.
