Subaortic Stenosis is a condition where the aortic outflow tract is narrowed.
Most frequently, this a result of a partially or fully encircling fibrous ring just below the aortic valve.
This can make it very difficult for blood to exit the left ventricle, causing
In moderate to severe cases, this will then cause severe left ventricular hypertrophy (thickening). This disease is “fixed” (non-progressive) after 1 year of age.
Patients with this condition (even mild) are at increased risk for infective endocarditis (infection of the heart valves).
Any suspicion of infection (urinary tract, respiratory, tooth root abscess, skin infection, etc.) should be immediately diagnosed and treated based on the results of a culture and sensitivity profile. With severe disease, these patients may develop ventricular arrhythmias and may have a higher incidence of sudden death.
Recheck physical examinations and electrocardiograms (ECGs) are recommended to monitor for any abnormal electrical activity that may require treatment.
