What this trial studies

This study aims to assess the safety and effectiveness of Stereotactic Body Radiotherapy (SBRT) as a non-invasive treatment for Hypertrophic Obstructive Cardiomyopathy (HOCM). Participants will be randomly assigned to receive either the SBRT treatment or a sham procedure. HOCM is characterized by obstruction of the left ventricular outflow tract, leading to significant health risks. The study seeks to provide an alternative to existing treatments, which may have limitations.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a confirmed diagnosis of HOCM and a left ventricular outflow tract pressure gradient of 50mmHg or greater.

Not a fit: Patients with advanced heart failure or those who have previously received invasive treatments for HOCM may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a safer, non-invasive option for patients suffering from HOCM.

How similar studies have performed: Early-stage studies have shown promising results for SBRT in cardiac applications, suggesting potential for success in this novel approach.
