Left atrial myxomas are rare cardiac tumors typically presenting with constitutional, obstructive, or embolic symptoms, often managed surgically with positive clinical outcomes. We describe a case of an 88-year-old woman presenting status post fall due to exertional dyspnea and progressive lower extremity edema, found to have an elevated HS-troponin, BNP, and a large left atrial mass on echocardiogram consistent with a cardiac myxoma. Given high surgical risk, palliative care was pursued. This case underscores the need to consider left atrial myxomas in new-onset heart failure.
