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

Q: What is the clinical evidence from this study?

Study design: Case Report. Population: 67-year-old woman presenting with non-ST-segment elevation myocardial infarction (NSTEMI) and normal coronary angiography due to left atrial myxoma (n=1). Intervention: Surgical excision of left atrial myxoma. Primary outcome: Resolution of myocardial ischemia and removal of left atrial myxoma with no residual mass or valvular abnormality.

Why the study?

Atrial myxomas are rare, benign cardiac tumors with the potential for serious embolic and obstructive complications.

Key Points

The aim is to highlight atrial myxoma as a rare cause of acute coronary syndrome and the importance of echocardiography.
Presented case of a 67-year-old woman with acute chest pain and NSTEMI.
Conducted coronary angiography, which showed normal results.
Used echocardiography to identify a large left atrial mass.
Confirmed diagnosis with transesophageal imaging.
Performed surgical resection and histopathological examination.
Identified large, stalk-attached left atrial myxoma via echocardiography.
Histopathology confirmed the tumor as a benign atrial myxoma.
Postoperative recovery was uneventful with positive follow-up echocardiography.

Intervention

Surgical resection

Demonstrates that left atrial myxoma can rarely present as NSTEMI with normal coronary arteries, emphasizing the diagnostic value of echocardiography.

Limitations

Single patient case report with no control group
No cardiac magnetic resonance imaging performed to definitively confirm MINOCA
Findings not generalizable due to case report nature

Implication

Echocardiography may identify treatable myxomas in NSTEMI with normal coronaries; leaves open broader screening impact.

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.

Mousati et al. (2026) conducted a case report in 67-year-old woman presenting with non-ST-segment elevation myocardial infarction (NSTEMI) and normal coronary angiography due to left atrial myxoma (n=1). Surgical excision of left atrial myxoma was evaluated on Resolution of myocardial ischemia and removal of left atrial myxoma with no residual mass or valvular abnormality. Surgical excision of left atrial myxoma resolved myocardial ischemia and resulted in a complete, uneventful recovery in a 67-year-old woman with NSTEMI and normal coronaries.
