What is angioplasty？

Angioplasty is a medical procedure used to treat narrowed or blocked blood vessels, typically in the arteries that supply blood to the heart. This procedure involves the insertion of a thin, flexible tube called a catheter into a blood vessel, usually in the groin or arm. The catheter is then guided through the blood vessel to the site of the blockage or narrowing, where a small balloon attached to the end of the catheter is inflated to widen the artery and restore normal blood flow.

The term angioplasty comes from the Greek words “angeion,” meaning vessel, and “plastikos,” meaning to shape or mold. Angioplasty was first performed in the 1970s and has since become a common and effective treatment for heart disease.

The most common type of angioplasty is called percutaneous transluminal coronary angioplasty (PTCA), which is used to treat narrowed or blocked coronary arteries that supply blood to the heart muscle. PTCA is often used to treat patients with angina (chest pain) or those who have had a heart attack.

During a PTCA procedure, the patient is given local anesthesia to numb the area where the catheter will be inserted. A small incision is made in the groin or arm, and a thin, flexible catheter is inserted into an artery and threaded up to the heart. A dye is then injected into the catheter, which helps the doctor to see the blockage on an X-ray machine.

Once the blockage has been located, a small balloon attached to the catheter is inflated, which compresses the plaque against the walls of the artery and opens up the vessel. In some cases, a stent (a small metal mesh tube) may be inserted into the artery to help keep it open.

The procedure typically takes 30-90 minutes, and patients are usually able to go home the same day or the following day. After the procedure, patients are usually advised to rest for a short period of time and to avoid heavy lifting or strenuous exercise for several days.

Angioplasty is a relatively safe procedure, but there are some risks involved, such as bleeding, infection, and damage to the artery or surrounding tissue. In rare cases, the balloon can cause a tear in the artery, which can lead to bleeding or a heart attack.

Despite these risks, angioplasty is generally considered a safe and effective treatment for heart disease. Studies have shown that angioplasty can reduce the risk of heart attack and death in patients with coronary artery disease, and can also improve symptoms such as chest pain and shortness of breath.

In conclusion, angioplasty is a minimally invasive medical procedure used to treat narrowed or blocked blood vessels, typically in the arteries that supply blood to the heart. This procedure involves the insertion of a thin, flexible catheter into a blood vessel, which is guided to the site of the blockage or narrowing. Once the blockage has been located, a small balloon attached to the catheter is inflated to widen the artery and restore normal blood flow. Angioplasty is a relatively safe and effective treatment for heart disease, and can reduce the risk of heart attack and death in patients with coronary artery disease.
