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. Despite encountering technical challenges, this innovative procedure represents a pioneering application of transcatheter surgery for managing left heart tumors.
