AI Article Synopsis
- * Researchers conducted a retrospective analysis comparing CDH cases with matched controls, measuring various cardiac dimensions at three key gestational ages.
- * Findings indicate that certain heart dimensions, especially involving the mitral valve and left ventricle, are significantly reduced in CDH cases and may serve as predictors for the severity of the condition.
Article Abstract
Objective: To serially assess fetal cardiac dimensions in congenital diaphragmatic hernia (CDH) and their relation to disease severity.
Study Design: Retrospective analysis of CDH cases and matched controls. Mitral (MVd) and tricuspid (TVd) valve diameters, left (LV) and right (RV) ventricular length and area, Z-scores, were serially assessed at 24-26, 30-32, and 35-37 weeks gestational age (GA).
Results: In CDH cases MVd, MVd Z-score, and LV area were significantly reduced at 24-26 and 35-37 weeks GA. TVd, TVd Z-score, and RV area were significantly reduced at 24-26 weeks. RV area Z-score increased with advancing GA. MVd and MVd Z-score were significantly lower at 24-26 weeks GA in CDH who had a combined outcome of death and/or ECMO.
Conclusions: LV hypoplasia in CDH is characterized by reduced MVd from 24 weeks GA. MVd, and the ratio of mitral and tricuspid valve diameters at later gestations, may be potential predictors of disease severity.

Background: Some mammals including the swine carry a fibrous vestigial clavicle, but a subclavius muscle (SBM) extends between the first rib and the supraspinatus muscle surface fascia. We aimed to examine development of the SBM and clavicle for finding a specific factor to provide the curious morphology.
Materials And Methods: Histological sections of early- and midterm fetuses of the swine, human and mouse were observed and compared at the almost same morphological stage.

Heterotopic pregnancy is defined as the concurrent presence of both an intrauterine pregnancy and an extrauterine (typically ectopic) pregnancy. This report presents the case of a 36-year-old female patient who presented to the emergency department with lower abdominal pain. A comprehensive evaluation, including transabdominal and transvaginal ultrasound imaging, revealed a heterotopic pregnancy at an estimated gestational age of six weeks and two days.

Background: Meconium is thick black-green fetal intestinal content starting from the early first trimester of gestation. Unfortunately, if it is released into the amniotic cavity due to any cause, it can be associated with neonatal mortality and morbidity.
Objective: To identify the factors associated with meconium-stained amniotic fluid among mothers undergoing emergency cesarean section in specialized hospitals cross-sectional study in south central Ethiopia from August 1, 2022, to 30, October 2022.

Background: Electrocardiograms (EKGs) are routinely performed in pregnant patients with pre-existing cardiovascular disease. However, in pregnant patients with congenital heart disease (CHD), EKG changes during gestation have not been explored.
Methods: We performed a retrospective study of pregnant patients with CHD enrolled in the STORCC initiative.
