A New Method Using the Four-Chamber View to Identify Fetuses With Subsequently Confirmed Postnatal Aortic Coarctation.
Echocardiography
March 2025
Division of Pediatric Cardiology, Department of Pediatrics, UCLA Mattel Children's Hospital, David Geffen School of Medicine at UCLA, Los Angeles, California, USA.
Objective: To determine the sensitivity, specificity, and false-positive rate among fetuses suspected prenatally to have coarctation of the aorta (CoA) using size and shape measurements of the fetal heart from the four-chamber view (4CV).
Methods: This was a retrospective study of 108 fetuses identified by pediatric cardiologists to be at risk for CoA. 4CV s from the last antenatal ultrasound performed by the cardiologists were analyzed.
Optical Flow-Enhanced Mamba U-Net for Cardiac Phase Detection in Ultrasound Videos.
IEEE Trans Med Imaging
March 2025
The detection of cardiac phase in ultrasound videos, identifying end-systolic (ES) and end-diastolic (ED) frames, is a critical step in assessing cardiac function, monitoring structural changes, and diagnosing congenital heart disease. Current popular methods use recurrent neu ral networks to track dependencies over long sequences for cardiac phase detection, but often overlook the short-term motion of cardiac valves that sonographers rely on. In this paper, we propose a novel optical flow-enhanced Mamba U-net framework, designed to utilize both short-term motion and long-term dependencies to detect the cardiac phase in ultrasound videos.

Int J Gynaecol Obstet
March 2025
Department of Obstetrics and Gynecology, The Edith Wolfson Medical Center, Holon, Israel.
Objective: We studied whether Doppler flow measurements before initiation of induction of labor (IOL) can predict non-reassuring fetal heart rate (NRFHR) monitoring in women at 38-41 weeks of gestation.
Materials And Methods: We performed a prospective observational study in a single tertiary medical center between November 2017 and December 2019. Women undergoing induction of labor were included.
Hemodynamic considerations for prenatal treatment of severe Ebstein anomaly with circular shunt based on two cases and review of the literature.
Arch Gynecol Obstet
March 2025
Department of Obstetrics and Prenatal Medicine, University Hospital Bonn, Venusberg-Campus 1, 53127, Bonn, Germany.
Prenatal severe Ebstein anomaly might be complicated by a circular shunt. In these cases, persistently elevated right atrial and venous pressure (due to severe tricuspid regurgitation) is complicated by a systemic ineffective blood shunt via a DA, resulting in diminished end-organ perfusion and acidosis, due to overall low cardiac output. Affected fetuses are at a significantly higher risk of intrauterine fetal demise.
