Insights

Surgical removal of a right atrial myxoma successfully treated a patient's right-to-left shunt and improved hypoxemia. This case highlights effective diagnosis and management of complex cardiac conditions.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Diagnostic Imaging

Background:

  • A 61-year-old male presented with a right atrial myxoma, coronary artery disease, and an interatrial shunt.
  • The shunt, through a patent foramen ovale, was linked to elevated central venous pressure from tricuspid valve disease.

Observation:

  • Diagnosis of the intracardiac shunt was achieved using an intraoperative blood-gas study.
  • This method was chosen over traditional right heart catheterization and cardioangiography.

Findings:

  • Surgical resection of the myxoma and patent foramen ovale closure were successfully performed.
  • Postoperatively, the patient experienced resolution of preoperative polycythemia and hypoxemia.

Implications:

  • This case demonstrates the successful surgical management of a complex cardiac tumor with associated intracardiac shunt.
  • Intraoperative blood-gas analysis offers a viable alternative for diagnosing shunts in specific clinical scenarios.
  • Effective treatment improved patient oxygenation and hematological parameters.
