Therefore, when patients come to the hospital for examination, it is often late, the heart valve is very narrow, leading to heart failure.

Mitral stenosis is one of the serious heart diseases over time, when the heart valve is attacked by immune complexes and gradually deformed. However, mild mitral stenosis often has few clinical manifestations, only when it is detected by laboratory examination, most of them have progressed to the severe stage leading to heart failure.

Minimally invasive open-heart surgery is an inevitable trend of medicine in the world as well as in Vietnam because of the outstanding advantages that this method brings in cardiovascular surgery.

Percutaneous balloon dilation is a non-surgical treatment for valvular stenosis. This is a simple procedure, minimally invasive, the patient remains fully awake during the procedure and the recovery time is very fast. Let's find out the basic information about this technique in the article below.
