Summary

Pulmonary sequestration can cause heart problems like mitral regurgitation due to abnormal blood flow. Surgical removal of the sequestration resolved the cardiac issues, avoiding the need for heart surgery.

Area of Science:

  • Cardiology
  • Thoracic Surgery
  • Pediatric Medicine

Background:

  • Pulmonary sequestration, a rare congenital lung malformation, typically presents with recurrent infections.
  • Cardiac complications, particularly those related to high-flow shunts, are uncommon presentations of pulmonary sequestration.

Observation:

  • A 4-year-old girl presented with symptoms suggestive of primary cardiac disease, including left atrial and ventricular enlargement and severe mitral regurgitation.
  • Cardiac catheterization and angiography revealed an unexpected large aortopulmonary shunt through an intralobar pulmonary sequestration.

Findings:

  • The patient underwent successful lobectomy, removing the pulmonary sequestration and the aortopulmonary shunt.
  • Post-operatively, significant improvement in cardiac chamber size and function was observed over a 2.5-year follow-up period.

Implications:

  • This case highlights that pulmonary sequestration can manifest as a high-flow cardiac lesion, mimicking primary heart disease.
  • Thorough evaluation of chest imaging is crucial for diagnosing pulmonary sequestration presenting with cardiac symptoms, potentially preventing unnecessary cardiac surgery.
