Background: Guidelines for echocardiographic evaluation of aortic regurgitation (AR) have not been validated against an independent quantitative standard.
Objectives: The aim of this study was to evaluate the accuracy of the ASE (American Society of Echocardiography) AR guidelines against cardiac magnetic resonance (CMR) and to develop simplified approaches for detection of significant AR.
Methods: Patients with AR underwent echocardiography and CMR <4 hours apart.
Article Synopsis
- This study focused on creating a specific model to evaluate the severity of aortic regurgitation (AR) in patients with continuous-flow left ventricular assist devices (LVAD), as there is no standard method for assessing AR in these cases.
- Researchers developed an echo-compatible flow loop using a 3D-printed left heart model from a patient with known significant AR and measured forward flow and regurgitant volume at various LVAD speeds.
- Results showed that the model successfully replicated the hemodynamics of AR in the patient, allowing for reliable measurements that can assist in studying echocardiographic parameters and improving clinical care for LVAD patients.
Myocardial ischemia in hypertrophic cardiomyopathy (HCM) is associated with poor outcomes. Vasodilator stress cardiac magnetic resonance (CMR) can detect and quantitate inducible ischemia in HCM patients. We hypothesized that myocardial ischemia assessed by CMR is associated with myocardial fibrosis and reduced exercise capacity in HCM.
