Insights
Surgical correction of aortico-right ventricular tunnel in a child was successful. Accurate diagnosis of coronary artery anatomy is crucial for successful surgical outcomes in these cases.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Defects
Background:
- Aortico-right ventricular tunnel is a rare congenital heart defect.
- Surgical correction is the standard treatment.
- Preoperative diagnosis of coronary artery anatomy is essential.
Observation:
- A 15-month-old child with aortico-right ventricular tunnel underwent successful surgical correction.
- The patient had normal coronary artery anatomy.
- Pledgeted sutures were used to close the aortic and right ventricular openings.
Findings:
- The surgical procedure was technically successful.
- The patient remained in excellent clinical condition at 12-month follow-up.
- No complications related to the surgical repair were noted.
Implications:
- Accurate preoperative assessment of coronary artery anatomy is critical for successful aortico-right ventricular tunnel repair.
- Failure to identify aberrant coronary arteries can complicate or prevent successful surgical correction.
- This case highlights the importance of thorough diagnostic workup before surgical intervention for congenital heart anomalies.
Abstract:
Aortico-right ventricular tunnel was successfully corrected in a 15-month-old child. Both the aortic and right ventricular openings were closed with pledgeted sutures. The coronary artery anatomy was normal. At 12-month follow-up the patient is in excellent clinical condition. Before surgical intervention for aortico-right ventricular tunnel is undertaken, every effort should be made to diagnose the coronary artery anatomy, because failure to do so in the case of aberrant origin of a coronary artery may prevent successful surgical correction.
