Coronary Artery Disease (Narrow/Blocked Blood Vessels)
What is coronary artery disease?
Coronary artery disease occurs when plaque (cholesterol, fat, calcium and other substances) builds up in the walls of your arteries, causing them to become narrow and restricting blood flow to the heart.
What are the symptoms?
- Chest pain (heaviness, pressure)
- Pain in your arms, neck or jaw
- Rapid or irregular heartbeat
What treatment options are available?
Coronary Artery Bypass Surgery (Open Heart Surgery)
Using a heart-lung bypass machine, doctors are able to rest your heart long enough for surgery. The heart-lung machine takes over the functions of the heart and lungs by cleansing and oxygenating the blood and pumping it through the body. After the surgery is complete, your heart and lungs resume this work.
Recently, it has been found that this type of surgery can also be conducted without using the heart-lung machine so long as a tiny portion of the heart, where the repair needs to take place, can be stabilized and quite still. During this minimally invasive bypass surgery, the surgeon can work on the repairs while the rest of the heart beats freely. This procedure has been perfected and is now referred to as "off pump" or beating heart bypass. In most all other ways, the surgery is similar to traditional bypass in that the incision is the same and the new vessel is joined to the blocked artery in the same way. But the fact that the heart is not stopped has many advantages for the patient including, less anesthesia is required because the operation is usually shorter, less need for blood transfusions and the hospital stay is often shorter.
Coronary & Peripheral Arthrectomy
Rotational Arthrectomy uses an abrasive burr near the tip of the catheter to grind the plaque into small particles that float harmlessly away in the bloodstream.
Directional Coronary Arthrectomy (DCA) positions the catheter window over the blockage. A rotating blade shaves the plaque and collects it in the catheter tip.
Extraction Arthrectomy uses an abrasive burr near the tip of the catheter to grind the plaque into small particles that are collected on the tip and extracted.
After the athrectomy, your doctor may do an angioplasty using a balloon catheter to compress any remaining plaque against the arterial wall. An arthrectomy usually lasts one to two hours.
