Abstract

Left ventricular outflow (LVOT) obstruction in patients with hypertrophic cardiomyopathy (HCM) is dynamic and sensitive to many variables that affect left ventricular preload, afterload, and contractility. The haemodynamic effect of normal respiration on LVOT obstruction has not been described.
