Extract

Introduction: Feature tracking is a new technique allowing measurement of right ventricular strains and strain rates from cardiac cine magnetic resonance imaging (MRI), based on the detection of image pattern motion during the cardiac cycle. This present work uses feature tracking MRI to investigate the modification of the right ventricle diastolic function in patients with Chronic Thromboembolic Pulmonary Hypertension (CTEPH).

Methods: Thirteen patients with suspected CTEPH were assessed by right heart catheterization (RHC) and cardiac MRI, including standard cine acquisitions during breath-hold. 4C, right and left 2C and short-axis views were used for feature tracking analysis. Global right ventricular longitudinal, circumferential and radial strain and strain rates were correlated with the mean pulmonary artery pressure (mPAP) measured during the RHC. Systolic, E and A decelerations (corresponding respectively to the early diastolic filling and to the atrial contraction) were measured from the descending slopes of the global longitudinal strain rates (in %.ms-2) (Figure1).
