Surgical experience with left atrial myxomas

Area of Science:

• Cardiology
• Cardiac Surgery
• Oncology

Background:

• Left atrial myxoma is a rare cardiac tumor.
• Clinical presentation often includes symptoms mimicking mitral stenosis.
• Diagnosis has evolved from cardiac catheterization to noninvasive imaging.

Purpose of the Study:

• To review surgical outcomes for left atrial myxoma.
• To evaluate diagnostic methods for cardiac tumors.
• To assess the necessity of long-term follow-up.

Main Methods:

• Retrospective analysis of 16 patients undergoing surgery for left atrial myxoma between 1974 and 1982.
• Review of clinical features, diagnostic procedures, surgical approaches, and outcomes.
• Comparison of historical diagnostic methods (cardiac catheterization) with modern noninvasive techniques (echocardiography, CT).

Main Results:

• All 16 patients survived surgery, with complete tumor removal achieved.
• Common symptoms included cardiac murmurs and mitral stenosis findings.
• Tumors originated from the atrial septum in most cases.
• Noninvasive imaging is now preferred for diagnosis, reserving catheterization for complex cases.

Conclusions:

• Surgical resection of left atrial myxoma is safe and effective.
• Noninvasive imaging modalities have largely replaced cardiac catheterization for diagnosis.
• Long-term surveillance with noninvasive methods is crucial for detecting recurrence.
