The aortic valve controls blood flow from your heart to the rest of your body. When this valve becomes narrowed—a condition known as aortic stenosis—blood flow is restricted, which can lead to symptoms like chest pain, dizziness, and breathlessness.
This procedure uses a balloon catheter to gently stretch open the narrowed valve, improving blood flow and easing symptoms. It may be recommended for patients who are not suitable candidates for open-heart surgery or TAVI as a palliative procedure.
