The intraventricular pressure difference (IVPD) is the diastolic suction from the base to the apex during early diastole. This diastolic suction has been shown to actively contribute to rapid filling, which requires adequate filling under low pressure. The IVPD is an important cardiac diastolic functional marker in adults, children, and fetuses. Originally, IVPD could be measured only by direct hemodynamic monitoring; however, velocity estimation was made in the acquired color M-mode imaging, which was analyzed using originally developed programming. In this paper, IVPD analysis in normal fetuses as well as in cases of congenital heart disease has been shown. The IVPD is a useful tool for evaluating fetal diastolic function.
