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 score
IUGR-Makikallio et al.
• Eight out of 75 neonates died before discharge
or had severe CP (n=2)
• Delivery at earlier gestational age 28 (range 2435) 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 scoreComplete 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.
