Faculty Disclosure Information

In the past 12 months, I have no relevant financial relationships with the manufacturer(s) of any commercial product(s) and/or provider(s) of commercial services discussed in this CME activity. I serve as co-PI of a study of Edoxaban for Daiichi-Sankyo.

I do not intend to discuss an unapproved/investigative use of a commercial product/device in my presentation.

Fetal congestive heart failure CV profile Score

1. Hydrops-– a measure of capillary permeability and/or elevated capillary venous pressure and/or hypoproteinemia

2. Venous Doppler-– a measure of central venous pressure, and/or RV diastolic function

3. Heart size-– a measure of remodeling of the heart in response to increased preload, afterload or anemia

4. Heart function - heterogenous measure of afterload and/or anular dilation (tricuspid valve regurgitation), (ventricular shortening), extreme diastolic filling abnormality (monophasic filling), and dP/dt estimate

5. Arterial Doppler-a measure of placental resistance and/or combined cardiac stroke volume at falling outputs

Validation of CVP scoreIUGR-Makikallio et al.

• Eight out of 75 neonates died before discharge or had severe CP (n=2)

• Delivery at earlier gestational age 28 (range 24-35) weeks vs. 35 (range 26-40) weeks, p<0.001

• Lower fetal CVP scores 4 (range 2-6) vs. 9 (range 5-10), p<0.001)

• All fetal subset scores of CVP except umbilical artery evaluation were lower (p<0.001) in the group with neonatal death.

Validation of CVP score-IUGR

• Neonates with 5-minute Apgar scores < 7 had lower CVP scores than with scores > 7 (6 (2-10) vs. 9 (5-10), p<0.001)

• Umbilical artery NT-proANP levels of newborns with CVP score < 6 were greater (5208 (2850-16030) pmol/L) than the levels of neonates with CVP exceeding 6 (1626 (402- 9574) pmol/L), p=0.0001).

• All NT-proANP values of newborns with CVP score <6 were above the 95th percentile NT-proANP value in normal pregnancies, while 42 out of 67 (63%) fetuses with CVP > 6 showed NT-proANP concentrations exceeding the 95th percentile value in normal pregnancies

• Umbilical artery NT-proANP values correlated inversely and significantly with CVP score values

Validation of CVP score-Complete AV Block

• We have implemented a strategy that includes the biophysical profile, which assesses fetal well-being, in combination with the cardiovascular profile that assesses cardiac function and the circulation.

• Two cases of fetal complete heart block in which early delivery was recommended due to worsening cardiovascular profile scores. Biophysical profile scores were normal. Both babies were successfully treated, despite having risk factors that predicted poor outcomes. We hypothesize that our management protocol initiated intervention before fetal compromise, hydrops, and myocardial damage occurred.

• We recommend an evaluation of heart function in addition to an assessment of fetal well-being in fetuses with complete heart block. Early delivery should be considered if there is evidence of distress and/or deteriorating cardiac function.
