Noninvasive ultrasound technique for assessment of liver fibrosis and cardiac function in Fontan-associated liver disease: diagnosis based on elastography and hepatic vein waveform type.

HV waveform can be used as a noninvasive measurable surrogate marker for CI. The RTE value increased overtime after the operation and would reflect liver fibrosis. The combination of RTE and HV waveform type could be useful noninvasive tools to evaluate clinical conditions in FALD patients in real time.
