摘要

•Stress echocardiography using LPP noninvasively evaluates preload reserve.•Preload reserve was impaired and ventricular interaction increased in TOF patients.•Significant PR was an important determinant of reduced preload reserve.•The LPP test may direct tailored treatment approaches and risk stratification.
