# Left Atrial Myxoma as a Rare Cause of Acute Coronary Syndrome: A Case Report

## TL;DR

A rare heart tumor caused chest pain and heart attack symptoms, but normal heart arteries; echocardiography helped diagnose and guide surgery for a full recovery.

## Contribution

Highlights left atrial myxoma as a rare cause of acute coronary syndrome and emphasizes the role of echocardiography in diagnosis.

## Key findings

- Atrial myxoma can present as acute coronary syndrome with normal coronary angiography.
- Echocardiography is crucial for identifying atrial myxomas.
- Early surgical resection leads to excellent prognosis.

## Abstract

Background and Clinical Significance: Atrial myxomas are rare, benign cardiac tumors, most commonly originating in the left atrium, with potential for serious embolic and obstructive complications. Case Presentation: We report a 67-year-old woman presenting with acute chest pain and NSTEMI whose coronary angiography results were normal. Echocardiography revealed a large, heterogeneous, stalk-attached left atrial mass, confirmed by transesophageal imaging. Surgical resection was performed two days after diagnosis, and histopathology confirmed it was an atrial myxoma. Postoperative recovery was uneventful, with reassuring follow-up echocardiography. Conclusions: Echocardiography remains an invaluable tool for the identification of atrial myxomas and early surgical excision is critical, as they have an excellent prognosis.
