Summary
Surgical removal of intracardiac myxomas, particularly left atrial myxomas, offers excellent long-term outcomes. This study shows successful excision with minimal mortality and no tumor recurrence in survivors.
Area of Science:
- Cardiology
- Cardiac Surgery
- Pathology
Background:
- Intracardiac myxomas are the most common primary cardiac tumors.
- Surgical management is the definitive treatment for myxomas.
Purpose of the Study:
- To evaluate the surgical outcomes and long-term results of intracardiac myxoma excision.
- To assess the efficacy of surgical techniques and the recurrence rates.
Main Methods:
- Retrospective review of 18 patients undergoing myxoma excision over 10 years.
- Surgical techniques included atrial septum resection with Dacron patch or direct suture reconstruction.
- Tumor tissue analysis using scanning electron microscopy in 8 cases.
Main Results:
- 16 left atrial and 2 right atrial myxomas were excised.
- 17 tumors were stalk-attached to the oval fossa.
- One early death (concomitant lobectomy) and one late non-cardiac death.
- All survivors were in New York Heart Association Class I at follow-up (average 36 months).
- Postoperative cardiac catheterization and echocardiography showed normal hemodynamics and no recurrence.
Conclusions:
- Surgical excision of intracardiac myxomas is a safe and effective procedure.
- Gratifying long-term results with no tumor recurrence are achievable.
- Morphological findings from scanning electron microscopy did not aid in pathological subcategorization.
