Abstract
Purpose of ReviewPulmonary arterial hypertension (PAH) is a devastating disease which can result in right heart (RH) failure and death. Herein, we discuss the current clinical applications of echocardiography in PAH.Recent FindingsAdvanced echocardiographic techniques (strain, strain rate, 2D-speckle tracking strain, and three-dimensional echocardiography) may reveal in the near future additional important insights into RH structure and function.SummaryAlthough right-heart catheterization is mandatory for a definitive diagnosis, echocardiography (resting and exercise) represents a key noninvasive imaging test on the diagnostic-prognostic-therapeutic PAH algorithm.
