[Ventricular septal defect in the first year of life (author's transl)]
Insights
Congenital heart defects in infants, including conal defects, often require early surgical intervention. Surgical repair, particularly pulmonary artery banding, significantly improves cardiac function and repolarization disturbances.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease Research
Context:
- Study focuses on congenital heart defects (CIV) in infants under one year.
- Highlights association with prematurity and malformations leading to cardiac failure.
- Investigates left ventricular hypertrophy in conal defects.
Purpose:
- To analyze clinical presentation, surgical outcomes, and management strategies for congenital heart defects in infants.
- To evaluate the effectiveness of surgical interventions like pulmonary artery banding and septal defect closure.
Summary:
- Presents 30 cases of congenital heart defects in the first year of life.
- 73% showed repolarization disturbances, with significant improvement post-banding.
- 15% experienced conduction disturbances after ventricular septal defect closure.
- 86% required surgery within the first year; total correction preferred after four months.
Impact:
- Provides insights into the management of complex congenital heart defects in neonates and infants.
- Emphasizes the importance of timely surgical intervention for improved cardiac outcomes.
- Informs surgical timing for total correction versus palliative procedures like banding.
Abstract:
Thirty cases of CIV in the first year of life are presented. Association with prematurity and other malformations anticipate cardiac failure. Left ventricular hypertrophy is more frequent in conal defects. Repolarization disturbances were found in 73% of the cases in left precordial derivation with significative relief after surgical repair (banding). Conduction disturbances after surgical closure of ventricular septal defect was found in 15% of the cases. Surgical treatment during the first year was needed in 86% of patients. Only one case had good evolution without surgery. After four months of life total correction of septal defect as prefered. In patients with previous pulmonary artery banding, correction must be made one or two years later.
