Managing Left Ventricular Outflow Tract Obstruction in Combined Aortic Stenosis and Hypertrophic Cardiomyopathy.

This study presents an elderly man with sequential hemodynamic obstructions caused by hypertrophic cardiomyopathy and aortic stenosis. Septal reduction therapy was performed to avoid outflow tract obstruction associated with potential future transcatheter aortic valve replacement. This case highlights the importance of resolving outflow tract obstruction during assessment of aortic valve disease.
