INTRODUCTION: Hypertrophic obstructive cardiomyopathy has been rising in prevalence, due to increased awareness and advanced imaging. For the symptomatic patient, pharmacological management remains an effective approach to the majority of patients with obstructive hypertrophic cardiomyopathy. However, a significant subset fails to improve sufficiently with medical therapy initially, or progressively becomes more symptomatic despite augmented medications over time. Most of the advances in the treatment of obstructive hypertrophic cardiomyopathy have therefore been made in the area of non-pharmacologic management, particularly septal reduction therapy. Both surgical myectomy and alcohol septal ablation have undergone iterative modifications that improve outcomes. Current guidelines support these therapies based on large observational studies, with choice of therapy based on a variety of factors but again based primarily on expert consensus opinion. Areas covered: This article reviews both pharmacological and non-pharmacological interventions to improve outflow tract obstruction and symptoms, and provides an algorithm for addressing the symptomatic obstructive patient. Expert commentary: Current options for hypertrophic cardiomyopathy allow the majority of patients to live their lives with no more than NYHA Class 2 heart failure symptoms. Treatment algorithms can add in identification of patients who may benefit from advanced therapies, and should be instituted routinely to improve care for the majority of patients with symptomatic hypertrophic cardiomyopathy.
