Angioplasty with stent placement is a minimally invasive procedure used to open narrow or blocked arteries. This procedure is used in different parts of your body, depending on the location of the affected artery. It requires only a small incision.
You have two chambers on the left side of your heart: your left atrium and your left ventricle. Your mitral valve, which is located between the two, is designed to allow blood to flow into the left ventricle but blocked from flowing back into the left atrium.
