Does transcoronary septal alcohol ablation compare favorably to surgical septal myotomy-myectomy in improving clinical, haemodynamic, and exercise outcomes in patients with hypertrophic obstructive cardiomyopathy?
While both procedures reduce obstruction and subjective symptoms, surgical myectomy provides superior objective exercise improvements and remains the gold standard for hypertrophic obstructive cardiomyopathy.
Surgical myectomy and alcohol septal ablation are equally effective at reducing obstruction and subjective exercise limitation in appropriately selected patients. However, the superior effect of surgical myectomy on exercise test parameters suggests that surgery remains the gold standard against which new treatment modalities should be compared.
