Background: The objective of our study was to assess the prenatal course, associated anomalies and postnatal outcome and the predictive value of various prenatal parameters for survival in prenatally diagnosed cases of truncus arteriosus communis (TAC). Methods: We evaluated cases from four centers between 2008 and 2021. Results: In 37/47 cases (78.7%), classification into a Van Praagh sbtype was possible, most had TAC type A1 (18/37 = 48.6%). In 33/47 (70.2%) with available valve details on common trunk valve, most presented with tricuspid valves (13/33 = 39.4%). In the overall sample, 14/47 (29.8%) had relevant insufficiency, and 8/47 (17%) had stenosis. In total, 37/47 (78.7%) underwent karyotyping, with 15/37 (40.5%) showing abnormal results, mainly 22q11.2 microdeletion (9/37 = 24.3%). Overall, 17/47 (36.2%) had additional extracardiac anomalies (17/47 = 36.2%). Additional intracardiac anomalies were present in 30/47 (63.8%), or 32/47 (68.1%) if coronary anomalies were included. Four (8.5%) had major defects. Two (4.3%) intrauterine deaths occurred, in 10 (21.3%) cases, the parents opted for termination, predominantly in non-isolated cases (8/10 = 80.0%). A total of 35/47 (74.5%) were born alive at 39 (35–41) weeks. Three (8.6%) pre-surgical deaths occurred in non-isolated cases. In 32/35 (91.4%), correction surgery was performed. The postoperative survival rate was 84.4% (27/32) over a median follow-up of 51.5 months. Initial intervention was performed 16 (1–71) days postpartum, and 22/32 (68.8%) required re-intervention. Regarding prenatal outcome-predicting parameters, no significant differences were identified between the survivor and non-survivor groups. Conclusions: There exist limited outcome data for TAC. To our knowledge, this is the largest multicenter, prenatal cohort with an intention-to-treat survival rate of almost 85%. [ABSTRACT FROM AUTHOR]

Background: The fetuses of pregnant women affected by anti-Ro/anti-La antibodies are at risk of developing complete atrioventricular heart block (CAVB) and other potentially life-threatening cardiac affections. CAVB can develop in less than 24 h. Treatment with anti-inflammatory drugs and immunoglobulins (IVIG) can restore the normal rhythm if applied in the transition period. Routine weekly echocardiography, as often recommended, will rarely detect emergent AVB. The surveillance of these pregnancies is controversial. Home-monitoring using a hand-held Doppler is a promising new approach. Methods: To obtain an overview of the current practice in Germany, we developed a web-based survey sent by the DEGUM (German Society of Ultrasound in Medicine) to ultrasound specialists. With the intention to evaluate practicability of home-monitoring, we instructed at-risk pregnant women to use a hand-held Doppler in the vulnerable period between 18 and 26 weeks at our university center. Results: There are trends but no clear consensus on surveillance, prophylaxis, and treatment of anti-Ro/La positive pregnant between specialists in Germany. Currently most experts do not offer home-monitoring but have a positive attitude towards its prospective use. Intensified fetal monitoring using a hand-held Doppler is feasible for pregnant women at risk and does not lead to frequent and unnecessary contact with the center. Conclusion: Evidence-based guidelines are needed to optimize the care of anti-Ro/La-positive pregnant women. Individual risk stratification could help pregnancy care of women at risk and is welcmed by most experts. Hand-held doppler monitoring is accepted by patients and prenatal medicine specialists as an option for intensified monitoring and can be included in an algorithm for surveillance.
