Surgical removal of a left atrial myxoma in a 72-year-old woman quickly resolved functional mitral stenosis. The procedure normalized heart function, demonstrating effective treatment for this rare cardiac tumor.
Area of Science:
- Cardiology
- Cardiac Surgery
- Oncology
Background:
- Left atrial myxomas are rare, benign cardiac tumors with potential for severe complications.
- Prompt surgical intervention is crucial to prevent embolic events, obstruction, and sudden death.
Purpose of the Study:
- To report a case of successful surgical excision of a large left atrial myxoma.
- To highlight the immediate hemodynamic improvement following tumor removal.
Main Methods:
- A 72-year-old woman with exertional dyspnea underwent elective median sternotomy.
- En bloc excision of a 4.7 cm x 2.7 cm left atrial mass was performed via a transseptal approach.
- Cardiopulmonary bypass and primary septal closure were utilized.
Main Results:
- Complete resection of the left atrial myxoma was confirmed postoperatively.
- The mean transmitral gradient decreased from 9 mmHg to approximately 1.4 mmHg, indicating rapid hemodynamic normalization.
- Mitral valve function was preserved throughout the procedure.
Conclusions:
- Valve-sparing transseptal excision effectively reverses myxoma-related functional mitral stenosis.
- Immediate normalization of the mean transmitral gradient signifies successful surgical outcomes.
