Pulmonary transit time measurement by contrast-enhanced ultrasound in left ventricular dyssynchrony

[摘要] BackgroundPulmonary transit time (PTT) is an indirect measure of preload and left ventricular function, which can be estimated using the indicator dilution theory by contrast-enhanced ultrasound (CEUS). In this study, we first assessed the accuracy of PTT
