Stereotactic radioablation for ventricular tachycardia

Area of Science:

• Cardiology
• Radiation Oncology
• Medical Physics

Background:

• Ventricular tachycardia (VT) is a life-threatening arrhythmia.
• Catheter-based ablation is the standard treatment but is not suitable for all patients.
• Non-invasive treatments are needed for refractory or ineligible VT cases.

Purpose of the Study:

• To review the clinical evidence for cardiac radioablation in treating VT substrate.
• To provide an overview of preclinical and translational research in cardiac radioablation.
• To outline a practical workflow for cardiac radioablation planning and treatment.

Main Methods:

• Review of current clinical evidence for cardiac radioablation.
• Analysis of preclinical and translational study results.
• Development of an expert consensus-based treatment workflow.

Main Results:

• Initial clinical results demonstrate promising short-term efficacy in VT suppression.
• Cardiac radioablation shows tolerable side effects in early studies.
• Preclinical and translational data support the feasibility of the approach.

Conclusions:

• Non-invasive stereotactic radioablation is a viable novel treatment for VT.
• The technique shows potential for patients unsuitable for or refractory to catheter ablation.
• A structured planning and treatment workflow is essential for successful implementation.
