This period of profound hypoxemia may have long-term implications, as previous studies demonstrated patients with d-TGA are at increased risk for neurocognitive delays despite effective surgical correction in the neonatal period. Balloon atrial septostomy (BAS) is an established intervention that improves intracardiac mixing and perioperative hemodynamics. This retrospective study aimed to quantify the time from birth to BAS and compare short-term outcomes for patients with prenatal and postnatal diagnoses of d-TGA. We identified 68 newborns born with d-TGA who were admitted to our facility between 2013 and 2022 and required BAS within 48 h after birth. Halfway through this study, our cardiac interventional team began traveling to a nearby delivery center where a bedside BAS could be performed prior to transferring the patient. We divided the patients into 3 groups-postnatal diagnosis (n = 27), prenatal diagnosis with rapid transport (n = 24), and prenatal diagnosis with interventional team performing a BAS at the delivery hospital (n = 17). The time from birth to BAS was significantly shorter for patients in the interventional program group (1.1 h) compared to the rapid transport (4.5 h) and postnatal diagnosis groups (9.3 h, p value < 0.01). The interventional program group also had lower lactate levels and less acidotic pH compared to the other groups. There was no significant difference in lowest oxygen saturation level, pre-surgical neurologic complication rate, time to surgery, or hospital length of stay.

However, extracting FECG signal from abdominal electrocardiogram (AECG) poses several challenges: (1) FECG signal is often contaminated by noise, and (2) FECG signal is frequently overshadowed by high-amplitude maternal electrocardiogram (MECG). To address these issues and enhance the accuracy of signal extraction, this paper proposes an improved Cycle Generative Adversarial Networks (CycleGAN) with integrated contrastive learning for FECG signal extraction. The model introduces a dual-attention mechanism in the generator of the generative adversarial network, incorporating a multi-head self-attention (MSA) module and a channel-wise self-attention (CSA) module to enhance the quality of generated signals. Additionally, a contrastive triplet loss is integrated into the CycleGAN loss function, optimizing training to increase the similarity between the extracted FECG signal and the scalp fetal electrocardiogram. The proposed method is evaluated using the ADFECG dataset and the PCDB dataset both from the Physionet. In terms of signal extraction quality, Mean Squared Error is reduced to 0.036, Mean Absolute Error (MAE) to 0.009, and Pearson Correlation Coefficient reaches 0.924. When validating the model performance, Structural Similarity Index achieves 95.54%, Peak Signal-to-Noise Ratio (PSNR) reaches 38.87 dB, and R-squared (R<sup>2</sup>) attains 95.12%. Furthermore, the positive predictive value (PPV), sensitivity (SEN) and F1-score for QRS wave cluster detection on the ADFECG dataset also reached 99.56%, 99.43% and 99.50%, respectively. On the PCDB dataset, the positive predictive value (PPV), sensitivity (SEN) and F1-score for QRS wave cluster detection also reached 98.24%, 98.60% and 98.42%, respectively. All of them are higher than other methods.
