Evaluation of Right Intraventricular Dyssynchrony by Two-Dimensional Strain Echocardiography in Patients With Pulmonary Arterial Hypertension

Right intraventricular dyssynchrony, as quantified by 2-dimensional strain echocardiography, is prevalent in PAH and is associated with more pronounced RV dysfunction. The clinical implications of these findings remain to be determined in follow-up studies.
