Abstract

Left atrial myxomas are rare but potentially serious tumors capable of causing systemic embolism and obstructive cardiac symptoms. We report the case of a 56-year-old woman with cardiovascular risk factors who was admitted for an acute ischemic stroke. Investigations revealed a large mass attached to the interatrial septum, highly suggestive of a myxoma, associated with biatrial dilation. Surgical excision was successfully performed. Subsequent Holter monitoring uncovered silent paroxysmal atrial fibrillation, requiring long-term anticoagulation therapy. This case highlights that even when an obvious embolic source such as a myxoma is identified, it remains essential to search for underlying pathologies, particularly atrial fibrillation, to optimize management and secondary prevention.
