Percutaneous Intramyocardial Septal Radiofrequency Ablation for Hypertrophic Obstructive Cardiomyopathy

The authors of this paper investigated the efficacy and safety of percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) in 15 patients with hypertophic cardiomyopathy (HOCM). At six months, they found significant reductions in peak left ventricular outflow tract gradients and intraventricular septal thickness. This also led to functional improvement, measured in NYHA class and total exercise time.  These results show that PIMSRA could potentially offer a less invasive alternative for surgical myectomy.
