Hypertrophic Cardiomyopathy in Heart Failure (NYHA Class II–IV) Without LVOT Obstruction

Clinical Scenario

This protocol addresses patients with hypertrophic cardiomyopathy who present with symptomatic heart failure (NYHA functional class II–IV). The defining features of this sub-population are the absence of left ventricular outflow tract (LVOT) obstruction and a left ventricular ejection fraction (LVEF) ≥ 50%.

In this setting, management of heart failure follows guideline-directed recommendations for patients without LVOTO, as outlined in the 2021 ESC Guidelines for acute and chronic heart failure.

Treatment Approach

For patients with progressive ventricular dysfunction that is refractory to medical therapy, the structured protocol addresses advanced interventional options — including mechanical and surgical strategies. The complete sequence of considerations, eligibility criteria, and stepwise approach is in the full protocol.
