Tracheoplasty should be proactively considered in the surgical strategy for treating the ring-sling complex.

OBJECTIVE: To examine the safety and effectiveness of proactive tracheoplasty for pediatric ring-sling complex. METHODS: We retrospectively collected data from 304 children who were diagnosed with a ring-sling complex and underwent surgery at 3 cardiac centers in China between January 2010 and June 2023. The children were categorized into 3 surgical groups: concurrent sling and tracheal surgery (group A; n = 258), staged sling and tracheal surgery (group B; n = 25), and sling-only surgery (group C; n = 21). We compared perioperative clinical characteristics, tracheal morphology changes, and outcomes across the 3 groups. RESULTS: The median age of the children was 1.2 years (interquartile range, [IQR], 0.7-1.9 years). The anomalous tracheobronchial arborization rates were higher in group A (52.5%) and group B (60.0%) compared to group C (15.0%). The preoperative narrow-wide ratio (NWR) was lower in groups A and B than in group C, with values of 0.44 (IQR, 0.35-0.52), 0.44 (IQR, 0.33-0.59), and 0.68 (IQR, 0.54-0.72), respectively (P < .001). Preoperative subcarina angles were similar among the groups (P = .54). After specific surgeries, the NWR and subcarina angle were improved significantly in groups A and B but not in group C. There were 7 in-hospital deaths and 2 postdischarge deaths. Respiratory symptoms improved in groups A and B, but 7 children in group C remained in respiratory dysfunction. Six children presented with residual stenosis of the left pulmonary artery. CONCLUSIONS: Concurrent sling and tracheal surgeries for children with the ring-sling complex are safe and effective and are especially preferable for those with NWR ≤0.6, long-segment or diffuse tracheal stenosis, anomalous tracheobronchial arborization, and pronounced respiratory symptoms.

Tricuspid mechanical valve replacement for severe tricuspid stenosis in a child who underwent surgical correction of complete atrioventricular septal defect, a rare long-term complications.

BACKGROUND: Complete atrioventricular septal defect is a complicated congenital heart malformations, and surgical correction is the best treatment, the severe tricuspid stenosis is a rare long-term complication after the surgery. CASE PRESENTATION: We report a case with the complication of severe tricuspid stenosis 7 years after the surgical correction of complete atrioventricular septal defect in a child. Then the patient underwent tricuspid mechanical valve replacement, Glenn, atrial septostomy, and circumconstriction of the right pulmonary artery. CONCLUSIONS: The patient recovered successfully with good short-term.

Risk factors of gastrointestinal bleeding after cardiopulmonary bypass in children: a retrospective study.

Background: During cardiac surgery that involved cardiopulmonary bypass (CPB) procedure, gastrointestinal (GI) system was known to be vulnerable to complications such as GI bleeding. Our study aimed to determine the incidence and risk factors associated with GI bleeding in children who received CPB as part of cardiac surgery. Methods: This retrospective study enrolled patients aged <18 years who underwent cardiac surgery with CPB from 2013 to 2019 at Shanghai Children's Medical Center. The primary outcome was the incidence of postoperative GI bleeding in children, and the associated risk factors with postoperative GI bleeding episodes were evaluated. Results: A total of 21,893 children who underwent cardiac surgery with CPB from 2013 to 2019 were included in this study. For age distribution, 636 (2.9%) were neonates, 10,984 (50.2%) were infants, and 10,273 (46.9%) were children. Among the 410 (1.9%) patients with GI bleeding, 345 (84.2%) survived to hospital discharge. Incidence of GI bleeding in neonates, infants and children were 22.6% (144/636), 2.0% (217/10,984) and 0.5% (49/10,273), respectively. The neonates (22.6%) group was associated with highest risk of GI bleeding. Patients with GI bleeding showed longer length of hospital stays (25.8 ± 15.9 vs. 12.5 ± 8.9, P < 0.001) and higher mortality (15.9% vs. 1.8%, P < 0.001). Multivariate logistic regression analysis showed that age, weight, complicated surgery, operation time, use of extracorporeal membrane oxygenation (ECMO), low cardiac output syndrome (LCOS), hepatic injury, artery lactate level, and postoperative platelet counts were significantly associated with increased risk of GI bleeding in children with congenital heart disease (CHD) pediatric patients that underwent CPB procedure during cardiac surgery. Conclusion: The study results suggest that young age, low weight, long operation time, complicated surgery, use of ECMO, LCOS, hepatic injury, high arterial lactate level, and low postoperative platelet counts are independently associated with GI bleeding after CPB in children.
