Article Abstract
Objective: To clarify the association between anesthetic technique and maternal and neonatal outcomes in parturients with congenital heart disease (CHD).
Design: Retrospective, observational cohort study.
Setting: An academic hospital.
Participants: A total of 263 consecutive parturients with CHD who underwent cesarean section from 1994 to 2019.
Interventions: None.
Measurements And Main Results: The authors compared postpartum cardiovascular events (composite of heart failure, pulmonary hypertension, arrhythmia, and thromboembolic complications) and neonatal outcomes (intubation and Apgar score <7 at one or five minutes) by anesthetic technique. Among 263 cesarean sections, general anesthesia was performed in 47 (17.9%) parturients and neuraxial anesthesia in 214 (81.3%) parturients. Cardiovascular events were more common in the general anesthesia group (n = 7; 14.9%) than in the neuraxial anesthesia group (n = 17; 7.9%). Generalized linear mixed models assuming a binomial distribution (ie, mixed-effects logistic regression), with a random intercept for each modified World Health Organization classification for maternal cardiovascular risk, revealed that general anesthesia was not significantly associated with cardiovascular events (odds ratio [OR], 1.00; 95% confidence interval [CI], 0.30-3.29). In addition, general anesthesia was associated with composite neonatal outcomes (Apgar score <7 at one or five minutes or need for neonatal intubation; OR, 13.3; 95% CI, 5.52-32.0).
Conclusion: Anesthetic technique is not significantly associated with postpartum composite cardiovascular events. General anesthesia is significantly associated with increased need for neonatal intubation and lower Apgar scores.

During pregnancy, significant physiological changes occur that result in cardiac remodeling and altered functional performance, though these are generally reversible postpartum. Pregnancy increases the cardiovascular system's demand, requiring substantial adaptations such as elevated cardiac output (CO), plasma volume, stroke volume (SV), and heart rate (HR), alongside a reduction in systemic vascular resistance (SVR) and mean arterial pressure. These adaptations, essential to meet the hemodynamic needs of both the mother and fetus, often differ from standard echocardiographic measurements used to evaluate cardiac function, making interpretation challenging.

Article Synopsis
- * A case report describes a 23-year-old pregnant woman with TA who experienced fainting and arm pulselessness; she was diagnosed early, enabling timely treatment and comprehensive care.
- * Despite developing gestational hypertension and other complications, a successful emergency cesarean section at 36 weeks resulted in a healthy recovery for both mother and child, highlighting the importance of early diagnosis and collaborative medical care.

Objective: This study aims to investigate the risk factors for severe postpartum hemorrhage (SPPH) in patients with placenta accreta spectrum (PAS) undergoing cesarean delivery, despite the prophylactic use of resuscitative endovascular balloon occlusion of the aorta (REBOA).
Materials And Methods: We conducted a retrospective case-control study on PAS patients who underwent cesarean delivery with prophylactic REBOA at the First Affiliated Hospital of Chongqing Medical University from January 2017 to December 2021. Prophylactic REBOA placement was determined by a prenatal ultrasound scoring system.
