|Congenital left ventricular outflow tract obstruction
A congenital cardiac condition in which the flow through the left ventricular outflow tract (proximal to the valve[s] guarding the outflow from the left ventricle) is blocked or impeded.

Congenital left ventricular anomaly
- Left ventricular hypoplasia
- Congenital left ventricular aneurysm or diverticulum
- Left heart obstruction at multiple sites
- Left ventricular myocardial sinusoids
This code should not be used for obstruction immediately under the arterial valve such as subaortic stenosis due to fibromuscular shelf or tunnel.
