Left ventricular strain and dyssynchrony by CMR Feature tracking in Idiopathic Pulmonary Arterial Hypertension(IPAH)

Conclusion: Impaired LV longitudinal strain and intraventricular dyssynchrony appear in IPAH. In the setting of impaired longitudinal function, LVEF is maintained by circumferential contraction. In IPAH with impaired LVEF, circumferential strain is impaired in addition to longitudinal strain.
