Percutaneous Excision of Left Atrial Myxoma Using Transcatheter Electrosurgery

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Left atrial myxoma is the most common primary cardiac tumor.
• Systemic embolization is a significant risk associated with left atrial myxoma.
• Conventional surgical excision is the standard treatment but carries risks for certain patients.

Observation:

• A case report details the management of a left atrial myxoma in a patient deemed high-risk for conventional surgery.
• The patient had cerebral amyloid angiopathy, increasing the risk of intracranial hemorrhage with surgery.
• A transcatheter electrosurgery approach was utilized via a transseptal route.

Findings:

• The procedure, while facing technical challenges, was successfully performed.
• This represents a pioneering use of transcatheter electrosurgery for left heart tumors.
• The novel approach addressed the myxoma in a patient unsuitable for traditional surgery.

Implications:

• Transcatheter electrosurgery presents a viable alternative for treating left atrial myxoma in high-risk individuals.
• This technique expands the options for managing cardiac tumors when conventional surgery is contraindicated.
• Further research into transcatheter techniques for cardiac tumors is warranted.
