Recognizing Dynamic LVOTO in Critical Care
Why a vigorous LV can still fail to deliver flow A small, vigorously contracting left ventricle can coexist with poor forward flow. Dynamic left ventricular outflow tract obstruction (LVOTO) is one possible explanation. Reduced filling, low vascular resistance and adrenergic stimulation can bring susceptible mitral tissue into the outflow tract during systole. Increasing contractility may […]
