Cardioembolic stroke caused by atrial myxoma.

A woman in her early 60s presented with multiple transient neurological symptoms over the course of 20 months, including transient loss of power to her right lower limb. Initial workup with CT brain scan, carotid dopplers and ECG revealed no abnormality; however, MRI of the brain suggested recent ischaemic events in separate cortical territories. Subsequent transoesophageal echocardiogram revealed a large mobile mass histologically confirmed to be an atrial myxoma.

Rationale: Thrombus is the most common occupying lesion in the cardiac chambers, it is often distinguished from cardiac neoplastic occupations. Among them, the most common is cardiac myxoma, whose imaging manifestations are often confused with thrombus. However, the 2 types of lesions have different therapeutic strategies and are both potentially high-risk sources of embolism, so early differentiation between intracardiac thrombus and cardiac tumor is essential.

Percutaneous Excision of Left Atrial Myxoma Using Transcatheter Electrosurgery.

Left atrial myxoma is the most prevalent primary cardiac tumor, known for its high risk of systemic embolization. Although surgical excision remains the standard treatment, options are limited for high-risk patients. This case report introduces a novel approach using transcatheter electrosurgery to address a left atrial myxoma via a transseptal approach in a patient ineligible for conventional surgery due to the heightened risk of intracranial hemorrhage associated with cerebral amyloid angiopathy.
