Patent ductus arteriosus before and after surgery.

Area of Science:

• Pediatric Cardiology
• Cardiovascular Surgery
• Congenital Heart Disease

Background:

• Patent ductus arteriosus (PDA) is a common congenital heart defect.
• Surgical intervention is a primary treatment for PDA.
• Understanding clinical presentation and surgical outcomes is crucial.

Purpose of the Study:

• To retrospectively analyze clinical characteristics, surgical management, and outcomes of PDA patients.
• To evaluate the correlation between hemodynamic parameters and imaging findings.
• To assess the long-term impact of surgical closure on growth and cardiac status.

Main Methods:

• Retrospective study of 25 patients with PDA undergoing surgical closure.
• Review of clinical data, echocardiography, electrocardiography, and cardiac catheterization findings.
• Analysis of surgical techniques (division vs. ligation) and postoperative follow-up.

Main Results:

• PDA predominantly affected females (4:1 ratio).
• Common findings included continuous murmurs, cardiomegaly, and left ventricular hypertrophy.
• Cardiac catheterization revealed varying degrees of pulmonary hypertension and flow.
• Early surgical intervention correlated with improved postoperative catch-up growth.
• No mortality was observed, and cardiomegaly resolved in patients followed for over a year.

Conclusions:

• Surgical closure of PDA is a safe and effective procedure with excellent long-term outcomes.
• Early surgical repair is associated with better catch-up growth in pediatric patients.
• Postoperative follow-up confirms the resolution of cardiac abnormalities and absence of mortality.
