[Aortic coarctation. Treatment under one year (author's transl)]

Area of Science:

• Pediatric Cardiology
• Cardiovascular Surgery
• Medical Diagnostics

Background:

• Aortic coarctation is a critical congenital heart defect requiring surgical intervention.
• Outcomes in infants with aortic coarctation vary significantly.
• Early diagnosis and effective surgical strategies are crucial for improving survival rates.

Purpose of the Study:

• To evaluate the surgical outcomes of aortic coarctation in infants.
• To assess the utility of electrocardiography (E.C.G.) in predicting surgical prognosis.
• To analyze the correlation between preoperative E.C.G. findings and patient survival.

Main Methods:

• Retrospective analysis of 15 pediatric patients operated on for aortic coarctation before one year of age.
• Surgical procedures included subclavian artery-aortic arch plasty and end-to-end anastomosis.
• Electrocardiography (E.C.G.) was used to evaluate cardiac status and surgical prognosis.

Main Results:

• Nine out of fifteen patients (60%) survived the surgery.
• Patients who did not survive exhibited right or biventricular hypertrophy with repolarization abnormalities on E.C.G.
• Fifty percent of survivors presented with left ventricular hypertrophy, indicating different E.C.G. patterns associated with survival.

Conclusions:

• Surgical intervention for aortic coarctation in infants can achieve favorable outcomes.
• Electrocardiography (E.C.G.) is a valuable tool for assessing surgical prognosis in pediatric aortic coarctation.
• Distinct E.C.G. findings correlate with survival and mortality, aiding in preoperative risk stratification.
