What this trial studies

This clinical trial evaluates the safety and efficacy of echocardiography-guided percutaneous radiofrequency ablation, known as the Liwen procedure, for treating cardiac tumors. It is a single-arm, prospective study conducted at Xijing Hospital, where patients with symptomatic cardiac tumors that cannot be surgically removed will receive the Liwen procedure. Participants will be monitored through follow-up assessments at various intervals to evaluate outcomes and safety. The study aims to provide an alternative treatment option for patients who are not candidates for traditional surgery.

Who should consider this trial

Good fit: Ideal candidates include patients experiencing hemodynamic changes or significant symptoms due to cardiac tumors who cannot undergo surgical resection.

Not a fit: Patients with severe arrhythmias, other significant heart diseases requiring surgery, or active infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this procedure could offer a minimally invasive treatment option for patients with cardiac tumors, potentially improving their quality of life and survival rates.

How similar studies have performed: While the approach of using echocardiography-guided radiofrequency ablation is innovative, similar techniques have shown promise in treating other types of tumors, suggesting potential for success in this context.
