NawaytouUniversity of California, San FranciscoUnited States EchocardiographyEchocardiography 2022; 39: 895-905DOI: 10.1111/echo.15397 AbstractIntroduction: Pulmonary artery acceleration time (PAAT) is considered useful for the non-invasive evaluation of pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR). PAAT is dependent on PAP, PVR, pulmonary artery compliance, […]
