The Evaluation of Right Ventricular Synchrony by Two‐Dimensional Speckle Tracking Echocardiography in Connective Tissue Disease‐Associated Pulmonary Arterial Hypertension

Numerous studies have demonstrated impaired right ventricular (RV) synchronicity in pulmonary arterial hypertension (PAH). However, few studies have focused on connective tissue disease (CTD)-associated PAH. This study evaluates RV dyssynchrony and its prognostic value in CTD-associated PAH.
