Bucks and injury. Over the last several years angioplasty has exceeded coronary bypass surgery as the preferred way to treat coronary artery disease. Optimistic coronary bypass patients are half as likely as pessimists to require re-hospitalization. The big bucks are in triple coronary bypass surgery, not routine visits to the doctor's office.
Symptoms. When diet, exercise and medicines don't provide adequate symptom relief, then CABG is indicated if the anatomy and other factors allow. There are other possible indications too.
Generally yes. The average mortality rate for coronary artery bypass surgery is between 1-3%, with 1% being the patients with the lowest risk and least complicated surgery and 3% being the most complicated of the surgeries.
Can be a good thing. All surgeries/procedures carry potential risks. The benefits of coronary bypass in the appropriately selected patients can far outweigh the risks.
Yes. Most patients who undergo coronary bypass surgery have 2 or 3 vessel coronary artery disease and do benefit from prolonged survival.
2 definitions. One definition is the avoidance of cardiopulmonary bypass or "off-pump." more classic definition is any surgery that avoids a stenotomy (dividing the breastbone). This can be done with a mini-thoracotomy or completely endoscopic with robotics.
Possible. There are some indications, and some risks. Many patients have multiple vessels involved and on the back of the heart. Standard operation gives great exposure, full revasculariazion with low risk through the years. Some minimal are also not so minimal!, when examined!
Only for acute dis. CABG and medical therapy in the long run have similar efficacy, but in acute situation surgery is very effective.
Works., Blockage of coronaries is a mechanical issue like a traffic jam. Detour= bypass allows traffic- blood to get to the destination. This relieves angina symptoms and in selected cases seems to prolong quality life.
Medication. However, medication is generally not nearly as good a substitute in terms of restoring adequate blood flow to the heart muscle as is bypass surgery in the patients who are recommended to have bypass surgery.
CABG. CABG is performed within the thoracic cavity.
Body cavity. Chest cavity.
