For more than 4 decades, surgical myocardial revascularization has proven to be one of the most effective and long-lasting therapies in the treatment of ischemic heart disease (IHD), especially in more complex anatomies. Coronary artery bypass grafting (CABG) is part of a routinely done revascularization intervention to manage coronary artery disease (CAD) by using grafted vessels to revascularize vessels distal from the blockage. The standard surgical approach for CABG involves anastomosis of the left internal mammary artery (LIMA) to the left anterior descending artery (LAD), or the use of a saphenous vein graft (SVG) or radial artery (RA) graft to bypass other coronary arteries. In recent years, bilateral internal mammary artery (BIMA) grafting has been used for patients undergoing surgical coronary revascularization for multivessel disease. In TACABG, all grafts are arterial and therefore no veins are used for revascularization, while in VCABG at least one graft derives from a vein. Arterial grafts are not only superior in terms of patency and survival, but they also protect the native coronary arteries against further progression of atherosclerotic disease. That’s why, TACABG is now very much time demanding technical approach for coronary revascularization.
Till today, TAS (Team Asraf Sium) has performed many of the TACABG cases with the ironclad success with the esteemed leadership of Dr Asraful Hoque Sium. This success has brought many tremendous outcomes of the patients which will be torch for the TAS during its journey in long run. Through the proper dedication and the promise to serve humanity, TAS believes to go farthest in this arena of Cardiac Surgery.
Coronary Artery Bypass Grafting (CABG)
Coronary Artery Bypass Grafting (CABG)
CABG is a type of surgery that improves blood flow to the heart. It’s used for people who have significant coronary artery disease (CAD).
Why they’re carried out?
Like all organs in the body, the heart needs a constant supply of blood. This is supplied by 2 large blood vessels called the left and right coronary arteries. Over time, these arteries can become narrowed and hardened by the build-up of fatty deposits called plaques. This process is known as atherosclerosis. People with atherosclerosis of the coronary arteries are said to have coronary heart disease (CAD).
CABG procedure at glance:
CABG is one treatment for CAD. During CABG, a healthy artery or vein from the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses the blocked portion of the coronary artery. This creates a new passage, and oxygen-rich blood is routed around the blockage to the heart muscle.
Other Names for Coronary Artery Bypass Grafting:
· Bypass surgery
· Coronary artery bypass surgery
· Heart bypass surgery
The goals of having CABG include:
· Improving quality of life and decreasing angina and other CAD symptoms
· Allowing patient to resume a more active lifestyle
· Improving the pumping action of heart if it has been damaged by a heart attack
· Lowering the risk of a heart attack (in some patients, such as those who have diabetes)
The doctor will decide whether you’re a candidate for CABG based on a number of factors, including:
· The presence and severity of CHD symptoms
· The severity and location of blockages in your coronary arteries
· Your response to other treatments
. Your quality of life
· Any other medical problems you have
The heart is a pump made of muscle tissue. It has 4 pumping chambers: 2 upper chambers, called atria, and 2 lower chambers, called ventricles. Valves between each of the heart’s pumping chambers keep blood flowing forward through the heart. Heart valve surgery is a procedure to treat heart valve disease. Heart valve disease involves at least one of the four heart valves not working properly. Heart valves keep blood flowing in the correct direction through your heart. The four valves are the mitral valve, tricuspid valve, pulmonary valve, and aortic valve. Each valve has flaps — called leaflets for the mitral and tricuspid valves and cusps for the aortic and pulmonary valves. These flaps open and close once during each heartbeat. Valves that don’t open or close properly disrupt blood flow through your heart to your body. In heart valve surgery, we repair or replace the affected heart valves. Many surgical approaches can be used to repair or replace heart valves, including open-heart surgery or minimally invasive heart surgery. Our treatment depends on several factors, including the patient’s age, health, the condition of the affected heart valve, and the severity of the condition. Why might a patient need heart valve repair or replacement surgery? Valve repair or replacement surgery is done to correct the problems caused by one or more diseased heart valves. If a patient’s heart valve(s) becomes damaged or diseased, he/she may has the following symptoms:
>Edema (swelling) of the feet, ankles, or abdomen (belly)
>Rapid weight gain due to fluid retention Outcome and Evaluation After Surgery:
>After heart valve surgery, the patient might be able to return to daily activities, such as working, driving, and exercise.
The patient will need to attend regular follow-up appointments with their doctor. He/she might have several tests to evaluate and monitor his/her condition.
The doctor might instruct the patient on making healthy lifestyle changes — including physical activity, a healthy diet, stress management, and avoiding tobacco use — to keep the heart working well.
>Doctor might recommend the patient to participate in cardiac rehabilitation — a program of education and exercise designed to help the patient to recover after heart surgery and improve his/her overall and cardiovascular health
