Quantification of biventricular myocardial strain from magnetic resonance images of pulmonary hypertensive patients using hyperelastic warping

Résumé

Pulmonary hypertension (PH) is a disease resulting from restricted flow in the pulmonary arterial circulation. This results in an increase in pulmonary vascular resistance. Left untreated, the disease leads to right ventricular (RV) failure, which is the most common cause of death in PH patients. The quantification of RV function is important for clinical management of PH patients, with clinical studies showing that the RV function is a major determinant of the functional capacity and prognosis in PH patients. Recent studies have demonstrated that the RV strain is associated with the RV function, and is a potentially useful prognostic marker in PH patients. Compared to quantifying strain in the left ventricle (LV), which can be approximated by a truncated ellipsoid, the in vivo quantitative assessment of the strain in the RV is challenging because of its complex geometry and thin wall. Here, we describe the application of a hyperelastic warping technique for quantifying RV strain in PH patients using regular CINE-MR images, which has the potential to overcome these challenges.
