Article Synopsis
- The study examines the outcomes of left atrioventricular valve (LAVV) operations in patients with atrioventricular septal defects (AVSD) over a 20-year period, highlighting the challenges and complications involved.
- Out of 843 patients with repaired AVSDs, 59 (7.3%) underwent LAVV operations, with notable rates of reoperation and valve replacement among them, particularly in those who had complex repairs.
- Key risk factors for adverse events included having a lower body weight and needing early LAVV surgery, while cleft closure during initial surgery appeared to provide some protective benefits.

Article Synopsis
- Long-term enlargement of the aortic arch after reconstruction in patients with hypoplastic left heart syndrome (HLHS) was studied using measurements from 50 patients who underwent Fontan completion.*
-
- Over time, the dimensions of the aortic arch increased significantly after reconstruction, with peak enlargement typically occurring around 7 to 12 months post-surgery, followed by a gradual decline in growth into adolescence.*
-
- Both Norwood and hybrid surgical strategies resulted in similar patterns of aortic arch enlargement, suggesting the need to investigate surgical factors that could optimize growth outcomes.*

Article Synopsis
- * A study included 25 patients aged around 6 months, with a mortality rate of 8.3% at 6 months and 17.6% at 5 years; nearly 50% of patients required a mechanical valve replacement within 3.5 years.
- * Complications like bleeding and thrombosis were low (87.5% freedom rate at 4 years), and early functional deterioration may require repeat surgeries, which can be performed safely.
