Cardiac myxoma is a source of emboli to the central nervous system and elsewhere in the vascular tree. However, nonspecific systemic symptoms and minor embolic phenomena may be overlooked in the absence of any history of cardiac problems. In this situation, cardiac investigations may not be performed, and diagnosis of this rare condition may be delayed until the onset of more significant embolic disease, such as stroke with functional impairment, as in the case reported here. The clinical presentation of cardiac myxoma is discussed, along with appropriate investigations and treatment, which may prevent such sequelae.

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.

Papillary fibroelastomas (PFEs) followed by cardiac myxomas (CM) are the 2 most common primary benign cardiac tumors. Although typically asymptomatic, they can manifest with nonspecific symptoms such as dyspnea and dizziness or more acute manifestations such as embolic events. We describe an unusual location of a PFE typically seen with a CM.

Cardiac myxomas are typically treated surgically; however, the operative mortality and recurrence rates are not negligible. In the current report we describe a case of repeat percutaneous aspiration of a right atrial myxoma. The report supports feasibility of the procedure, provides the asymptomatic timeframe after debulking, and the regrowth rate.

Surgical resection is standard of care for the treatment of atrial myxoma. However, the optimal management strategy for recurrent cardiac tumors is less clear. Here we report the novel use of a catheter-based device retrieval system for the removal of a recurrent cardiac myxoma.
