Core Tip
Core Tip: Left ventricular outflow tract (LVOT) obstruction is a condition in which the LVOT is obstructed. Aortic valve stenosis and hypertrophic cardiomyopathy are the most common causes of LVOT obstruction. We report a case of severe aortic stenosis and hypertrophic obstructive cardiomyopathy that underwent aortic valve replacement and myectomy. Management of patients with hypertrophic obstructive cardiomyopathy and systolic anterior motion remains a clinical challenge. Bedside echocardiogram guided therapeutic decisions has central role in such complex case patients to improve outcome. Vasopressin has been shown to reduce LVOT gradient and seems to be the vasoconstrictive drug of choice in such patients.
