Left Ventricular Outflow

Left ventricular outflow tract obstruction can occur at subvalvar, valvar, and supravalvar levels. Severity and progression can be evaluated by echocardiography. Aortic valve stenosis can usually be relieved by balloon valvotomy, but some patients require surgery, either with valvotomy, valve replacement, or the Ross procedure. Sub- and supravalvar aortic stenosis require surgical management. Long-term follow-up of all patients is required.

Left Ventricular Outflow

The authors describe a patient with hypertrophic cardiomyopathy with concomitant left ventricular outflow tract obstruction and aortic stenosis. Detailed haemodynamic assessment of the serial lesions was performed. Alcohol septal ablation resulted in a significant reduction of gradients across the left ventricular outflow tract.
