Summary

Echocardiography alone provides adequate noninvasive preoperative evaluation for pediatric open-heart surgery. This study found noninvasive methods accurately diagnosed most congenital heart disease cases, reducing the need for invasive procedures.

Area of Science:

  • Pediatric Cardiology
  • Diagnostic Imaging
  • Surgical Evaluation

Background:

  • Echocardiography is increasingly used for noninvasive preoperative assessment in pediatric cardiac surgery.
  • Accurate preoperative diagnosis is crucial for optimizing surgical outcomes in children with congenital heart disease.

Purpose of the Study:

  • To assess the diagnostic accuracy of noninvasive (echocardiography) versus invasive (catheterization) preoperative evaluations in pediatric patients undergoing open-heart surgery.
  • To determine if echocardiography alone is sufficient for preoperative diagnosis in this population.

Main Methods:

  • Prospective evaluation of diagnostic accuracy comparing preoperative findings with intraoperative diagnoses.
  • Comparison included surgical inspection and routine perioperative transesophageal echocardiography.

  • Patients underwent either noninvasive echocardiography or invasive catheterization preoperatively.

    • Main Results:

    • In 142 patients (68%) with echocardiography, 12 (8.5%) had previously undiagnosed findings, with 2 considered significant.
    • In 67 patients (32%) with catheterization, 4 (6%) had additional findings, modifying surgery in 2.
    • One neonate with transposition of the great arteries and an undiagnosed intramural coronary artery died postoperatively.

    Conclusions:

    • Echocardiography alone can adequately support the diagnostic work-up for many pediatric open-heart operations.
    • Noninvasive evaluation using echocardiography is a reliable method for preoperative assessment in children with congenital heart disease.
    • Minimizing invasive procedures can enhance patient safety and streamline preoperative care.
