This case report details an exceptionally large atrial myxoma originating from the eustachian valve, a rare cardiac tumor. Surgical removal was successful, highlighting a significant finding in cardiovascular pathology.
Area of Science:
- Cardiovascular Medicine
- Cardiac Pathology
- Surgical Oncology
Background:
- Eustachian valve myxomas are exceptionally rare cardiac tumors.
- Atrial myxomas can present with significant morbidity if left untreated.
Purpose of the Study:
- To report a rare case of a large eustachian valve myxoma.
- To describe the diagnostic and therapeutic approach for this unusual cardiac mass.
Main Methods:
- A 72-year-old woman with dyspnea underwent comprehensive echocardiography.
- Transesophageal echocardiography revealed a large mass on the eustachian valve.
- Surgical resection of the mass and tricuspid valve replacement were performed.
Main Results:
- A 75 mm x 44 mm multilobulated mobile mass was identified, originating from the eustachian valve.
- The mass extensively occupied the right atrium and ventricle, extending into adjacent structures.
- Histopathology confirmed the diagnosis of atrial myxoma.
Conclusions:
- This represents the largest reported myxoma arising from a eustachian valve.
- Successful surgical management is feasible for large eustachian valve myxomas.
