The echocardiograms assessed the atrioventricular (AV) interval – which is prolonged in 1° AVB – and heart rate and looked for anti-Ro/SSA conduction system and cardiac disease. Surveillance echocardiograms were performed weekly or biweekly (per site protocol) and diagnostic echocardiograms any time abnormal FHRM was detected during the study. Pregnant women who tested positive for anti-Ro/SSA antibodies were invited to participate. Sixteen centers participated in this international multicenter prospective study led by Bettina Cuneo, MD, former Director of Fetal Cardiology at Children's Colorado. Study methods: Using echocardiograms and hand-held Dopplers for fetal heart rate monitoring in Sjogren's pregnancies ![]() The current study adds to the previous study, summarizing the results and outcomes of 273 anti-Ro/SSA pregnancies monitored at home and by echocardiography. Mothers in the study performed fetal heart rate monitoring twice per day and underwent a fetal echocardiogram within six hours of detecting an abnormal fetal heart rhythm. ![]() In a previous study, our researchers in the Colorado Fetal Care Center at Children's Hospital Colorado determined feasibility of fetal heart rate and rhythm monitoring (FHRM) to be done at home by mothers with a commercially available Doppler. Since this transition from normal rhythm to CAVB occurs in less than 24 hours, weekly or biweekly echocardiographic surveillance rarely detects 2° AVB and the window of opportunity for treatment. While the fetal heart transitions from normal to un-reversible complete AVB (CAVB) or 3° AVB, it passes through 2° AVB, which is reversible. ![]() Research background: Pregnant mothers with anti-Ro/SSA antibodies are at risk of developing fetal heart blockįetal heart block (AVB) is an uncommon yet life-threatening condition that occurs in about 2% of mothers with anti-Ro/SSA (Sjogren's) antibodies.
