April 23, 2014, 1:30-2:00 PM Perinatal Cardiology Cardiology for the fetus, child, and mother 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 CV Profile 10-point score NORMAL -1 POINT Hydrops None (2 pts) Ascites or Pleural effusion or Pericardial effusion Venous Doppler (Umbilical Vein) (Ductus Venosus) DV (2 pts) DV -2 POINTS Skin edema UV pulsations UV Heart Size (Heart/Chest Area) < 0.35 0.35 - 0.50 >0.50 or <0.20 (2 pts) Cardiac Function Normal TV & MV RV/LV S.F. > 0.28 Biphasic diastolic filling (2 pts) Arterial Doppler (Umbilical artery) UA (Normal) (2 pts) Holosystolic TR or RV/LV S.F. < 0.28 Holosystolic MR or TR dP/dt < 400 or Monophasic filling UA (REDV) UA (AEDV) Future Research • Disease – specific CVP Score • Prospective trial of digoxin in fetal CHF • Comparison with Biophysical Profile Score • First Trimester CVP Score • Mouse embryo CVP Score Future Research • Disease – specific CVP Score • Prospective trial of digoxin in fetal CHF • Comparison with Biophysical Profile Score • First Trimester CVP Score • Mouse embryo CVP Score Heart to chest area ratio Valve regurgitation Hofstaetter C, Hansmann M, Eik-Nes SH, Huhta JC, Luther SL, A cardiovascular profile score in the surveillance of fetal hydrops, J Matern Fetal Neonatal Med, 2006, 19(7):407-13 100 hydropic fetuses CVP score range-last exam 3-10 6 died-Median CVP score 6 versus 7 Detection of CHD-Disproportion Fetal Congestive Heart Failure Abnormal Venous Doppler Gudmundsson S, Huhta JC, Wood DC, Tulzer G, Cohen AW, Weiner S: Venous Doppler ultrasonography in the fetus with non-immune hydrops.

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. • Donofrio MT, Gullquist SD, Mehta ID, Moskowitz WB.Congenital complete heart block: fetal management protocol, review of the literature, and report of the smallest successful pacemaker implantation.
