Sequential Changes in Right Ventricular Straein During the Development of Pulmonary Hypertension Assessed With Magnetic Resonance Feature Tracking: An Animal Study.
OBJECTIVE To evaluate the sequential changes in right ventricular (RV) strain and histological vascular remodeling and their correlations during pulmonary hypertension (PH) development in a rat model by using cardiac magnetic resonance (CMR)-feature tracking (FT). MATERIALS AND METHODS Separate cohorts of six-week-ol...
