Abstract

Hypertrophic cardiomyopathy (HCM), a heterogeneous genetic heart disease with global distribution, is an important cause of heart failure disability at any age. For 50 years, surgical septal myectomy has been the preferred and primary treatment strategy for most HCM patients with progressive, drug refractory functional limitation due to left ventricular (LV) outflow tract obstruction. With very low surgical mortality at experienced centres, septal myectomy reliably abolishes impedance to LV outflow and heart failure-related symptoms, restores quality of life, and importantly is associated with long-term survival similar to that in the general population. Nevertheless, alternatives to surgical management are necessary for selected HCM patients. For example, after a brief flirtation with dual-chamber pacing 20 years ago, percutaneous alcohol septal ablation has garnered a large measure of enthusiasm and a dedicated following in the interventional cardiology community, achieving benefits for patients, paradoxically, by virtue of producing a transmural myocardial infarct. However, an unintended consequence has been the virtual obliteration of the surgical option for HCM patients in Europe, where several robust myectomy programmes once existed. Therefore, clear differences are now evident internationally regarding management strategies for symptomatic obstructive HCM. The surgical option is now unavailable to many patients based solely on geography, including some who would likely benefit more substantially from surgical myectomy than from catheter-based alcohol ablation. It is our aspiration that this discussion will generate reconsideration and resurgence of interest in surgical septal myectomy as a treatment option for severely symptomatic obstructive HCM patients within Europe.
