[Interventions on the heart and large vessels without prior heart catheterization]

Area of Science:

• Pediatric Cardiology
• Diagnostic Imaging
• Surgical Intervention

Context:

• Congenital cardiac malformations require accurate preoperative diagnosis for safe surgical outcomes.
• Historically, cardiac catheterization and angiocardiography were standard diagnostic procedures.
• Evaluating non-invasive diagnostic methods is crucial for improving patient care and reducing procedural risks.

Purpose:

• To assess the safety and accuracy of diagnosing congenital cardiac malformations using exclusively non-invasive methods.
• To compare surgical outcomes between patients diagnosed non-invasively and those diagnosed with traditional invasive methods.
• To determine the feasibility of relying solely on clinical investigation, ECG, X-ray, and echocardiography for surgical planning.

Summary:

• 161 children with congenital heart defects underwent surgery based solely on non-invasive diagnostics (clinical evaluation, ECG, X-ray, echocardiography).
• Common procedures included patent ductus arteriosus ligation, aortic coarctation repair, and atrial septostomy.
• Outcomes were compared to a group that underwent cardiac catheterization; no deaths occurred due to diagnostic errors in either group.

Impact:

• Demonstrates that a significant range of congenital heart malformations can be safely operated on using only non-invasive preoperative diagnoses.
• Highlights echocardiography's effectiveness in diagnosing complex pediatric cardiac conditions.
• Suggests a potential shift towards less invasive diagnostic protocols in pediatric cardiac surgery, improving patient safety and reducing healthcare costs.
