WebJul 7, 2024 · As pregnancy progresses and the vascular tree undergoes trophoblastic transformation, the walls of these vessels become less muscular creating a low-resistance, high-capacitance system. As a result, first-trimester uterine artery waveforms demonstrate a high pulsatility index and an early diastolic notch. Webwaveform shows a steep systolic slope, an early diastolic notch and a small amount of diastolic flow. The waveform is essentially a high resistance form in the non-pregnant state. As the pregnancy progresses, there is gradual removal of the notch and an increase in the diastolic flow, as seen by the fall in resistance index (RI) (4).
