Some patients will only need careful monitoring, but many will benefit from medication. Medicines can often be effective in alleviating symptoms and help manage the workload on the heart.

Some patients will eventually need some type of heart surgery. For those with more severe forms of subaortic stenosis, heart surgery may involve procedures to remove or repair the blockage.

Surgery can stop subaortic stenosis symptoms from getting worse, but it doesn’t cure the condition. During subaortic stenosis surgery, the surgeon removes the membrane or muscle that causes the blockage. About 65 percent of patients who undergo surgery are symptom-free 10 years after their surgery. Some patients will need a second surgery to repair leaking heart valves or if the obstruction returns.

The goal of all treatments is to alleviate symptoms, improve blood flow and prevent complications. If the subaortic stenosis is severe and cannot be effectively treated with other methods, surgical replacement of the aortic valve may be considered. This can involve mechanical or biological (tissue) valves.

This surgery involves removing the excess tissue obstructing the subaortic region. It is often recommended for individuals with severe subaortic stenosis.

This less invasive procedure uses alcohol injection to selectively destroy the excess tissue causing the obstruction. It is an alternative to surgical myectomy.

In this minimally invasive procedure, a catheter with a balloon on the tip is used to stretch and widen the narrowed area of the aorta.
