Fetal cardiac function does not follow adult rules and missing that distinction is where assessments go wrong. This post covers a systematic 4-pillar approach to fetal cardiac function assessment: systolic function, diastolic filling, the MPI/Tei Index, and venous Doppler, with the CVP Score, an 8-step scan protocol, and the full hierarchy of cardiac compromise from…
