Coronary Artery Bypass Grafting
Coronary Artery Bypass Grafting is the most common open-heart surgery procedure. It is used to treat people who have severe blockages of the coronary arteries. These blockages are caused by plaque which builds up inside the coronary arteries and blocks the supply of oxygen-rich blood to the heart.
During CABG, the surgeon takes healthy arteries or veins from other parts of the body and sews them to a normal part of the coronary artery past the blockage thereby bypassing the blockage. The grafted arteries or veins reroute the blood around the blocked portion of the artery to supply oxygen-rich blood to the heart muscle. A patient may undergo multiple bypass grafts depending on the number of clogged arteries.
This procedure improves the supply of blood and oxygen to the heart, relieves chest pain, reduces the risk of a future heart attack, and improves the patients ability for physical activity that has been limited by the ability of the heart to maximize its pumping because of a lack of blood flow.
How Should I Prepare For Open
To prepare for open-heart surgery, you should follow your healthcare providers recommendations about:
- Medications: You may need to stop taking certain medicines a week or two before surgery. People often stop blood thinners and nonsteroidal anti-inflammatory drugs . These medicines can increase bleeding risk.
- Food and drink: Your healthcare team will ask you to fast before your surgery. Anesthesia is safer on an empty stomach.
- Smoking and alcohol: Cut back on alcohol and quit smoking. Both can slow postsurgical healing and increase the risk of complications.
Procedure Completion Both Methods
Your doctor will sew the sternum together with small wires .
He or she will insert tubes into your chest to drain blood and other fluids from around the heart.
Your doctor will sew the skin over the sternum back together.
Your doctor will put a tube through your mouth or nose into your stomach to drain stomach fluids.
He or she will then apply a sterile bandage or dressing.

What Are The Reasons For Open
Patients most commonly benefit from these procedures for the following purposes:
- Treat occlusive coronary heart disease
- Repair or replace heart valves which control blood flow through the heart
- Repair abnormal holes or damaged structures in the heart, often because of infection
- Implant medical devices to help control the heartbeat or support heart function and blood flow
- Replace a damaged heart with a healthy heart from a donor
Pulmonary Complications Following Cardiac Surgery
As stated, pulmonary complications are an unavoidable complication following CABG surgery . Various studies have shown a different outbreak in patients ranging from 3 to more than 50% . However, the occurrence of PC following cardiopulmonary bypass surgery is a multivariate outcome that should be studied according to the preoperative, perioperative and postoperative. Therefore, we will investigate the effective factors in the occurrence of PC following Cardiac surgery during these periods, and then we will explain the various types of pulmonary diseases following CABG surgery.

Are There Alternatives To Standard Open
Thanks to medical advancements, many procedures that once required opening the chest can now take place using minimally invasive heart surgery or with small incisions. The surgeon sometimes still needs to cut through part of the breastbone .
Depending on your situation, your surgeon may be able to use these methods:
- Catheter-based: Your surgeon threads a catheter to the heart. The surgeon then inserts surgical instruments, balloons, or stents through the catheter to perform a procedure. Catheter-based procedures include transcatheter aortic valve replacement and coronary angioplasty and stenting.
- Video-assisted thoracic surgery : Your surgeon performs VATS by inserting a tiny video camera and surgical instruments into several small chest incisions. Your surgeon may use VATS to place a pacemaker, repair heart valves or treat an arrhythmia.
- Robotically-assisted: Certain patients with valvular heart disease, cardiac tumors, atrial fibrillation and septal defects may be candidates for this minimally invasive approach.
What Is Open Heart Surgery
Open heart surgery is any surgery in which the surgeon cuts open the chest to operate on the heart. Open heart surgery can treat a variety of diseases and conditions of the heart. Conditions commonly treated with open heart surgery include heart valve disease, birth defects of the heart, and coronary artery disease. Coronary artery disease is the leading cause of heart attack.
Your heart is made of specialized muscle tissue that pumps blood through your body. Blood moves through the four chambers of the heart in a precise manner controlled by electrical signals. Valves help coordinate the movement of blood through the heart. The coronary arteries are blood vessels that supply your heart muscle with blood.
Open heart surgery is a common but major surgery with significant risks and potential complications. You may have less invasive treatment options. Consider getting a second opinion about all your treatment choices before having open heart surgery.

Heart Procedures And Surgeries
If you’ve had a heart attack, you may have already had certain procedures to help you survive your heart attack and diagnose your condition. For example, many heart attack patients have undergone thrombolysis, a procedure that involves injecting a clot-dissolving agent to restore blood flow in a coronary artery. This procedure is administered within a few hours of a heart attack. If this treatment isn’t done immediately after a heart attack, many patients will need to undergo coronary angioplasty or coronary artery bypass graft surgery later to improve blood supply to the heart muscle.
See diagnostic tests and procedures to better understand the tests you may have to undergo to find out if you had a heart attack, how much damage was done and what degree of coronary artery disease you have.
How Do You Prepare For Bypass Surgery
Before your surgery, youâll get blood tests, chest X-rays, and an electrocardiogram . Your doctor may also do an X-ray procedure called a coronary angiogram. It uses a special dye to show how the blood moves through your arteries.
Your doctor will also let you know if you need to make any changes to your diet or lifestyle before the surgery and make any changes to medicines you take. Also tell your doctor about any vitamins and supplements you take, even if they are natural, in case they could affect your risk of bleeding.
Youâll also need to make plans for recovery after your surgery.

What Is Recovery Like After Open
Recovery time varies depending on the surgery type, complications and your overall health before surgery. It can take 6 to 12 weeks to recover from an open-heart procedure.
Your surgeon will let you know when you can return to work and other activities. Typically, you shouldnt drive or lift anything heavy for the first six weeks.
Some people need to take blood thinners after heart surgery to prevent blood clots. Your healthcare provider may also recommend cardiac rehabilitation. This medically supervised program can help you regain strength and stamina and improve overall heart health.
Immediately After Heart Bypass Surgery
You should talk to the medical staff if you have any fears or anxieties over the few days immediately after the operation, as emotional stress can make demands on your heart.Following the operation:
- You spend a day or two in the intensive care unit. You have numerous monitors attached to you that are located by your bed.
- You have a couple of intravenous lines to keep your body fluids and electrolyte levels in balance.
- The medical and nursing staff are trained to look out for any complications or potential complications. They keep an expert eye on your heart tracings, and treat any irregularities if they arise.
- You have a nasogastric tube to drain any excess stomach fluids, and a tube into your bladder to drain off and measure your urine output.
- You are shown how to care for your wounds. Often, washing with soap and water is enough.
- You are given advice on angina , such as how to treat it and when to get medical help.
- Your doctor advises on when you can return to work, resume driving, and exercise strenuously.
- You are shown breathing exercises and other exercises by a physiotherapist.
- Before you leave hospital, your doctor should provide guidelines about restarting sexual activity. You should be given advice on positions that reduce exertion during sex, and what to do if you experience angina.

Complications With Coronary Artery Bypass Surgery
Coronary artery bypass surgery is a procedure used to restore blood and oxygen flow to the heart muscle after being restricted due to coronary artery disease. The operation is designed to bypass the area of the blood vessel in which a clot exists by taking a healthy vein from another area in the body and creating a new path for blood and oxygen to reach the heart. Most patients remain symptom-free for several years, but in rare cases, life-threatening complications exist.
Heart Attack Or Stroke
Heart attack and brain stroke are dangerous complications of open-heart surgery. The risk is high in patients who undergo aortic valve replacement. Further, almost 2-3% of the patient undergoing coronary artery bypass surgery suffers from brain stroke. A brain stroke is a condition that develops when blood flow to the brain becomes insufficient or completely stopped.

Left Ventricular Embolization Of An Aortic Balloon
An 83-year-old man with severe symptomatic aortic stenosis, deemed to be at high risk for conventional surgery was referred to our institution for a transcatheter aortic valve implantation. A transapical approach was chosen because his anatomic features were not suitable for transarterial access. The aortic annulus measured by transesophageal echocardiography was 23.8 mm .
A 26-mm Edwards SAPIEN valve was implanted with fluoroscopy and TEE guidance with one-step inflation, as previously described.1 Although there were no technical problems during deployment, the prosthesis embolized into the left ventricle a few seconds after hemodynamic recovery . The stiff wire was kept in place, preventing the prosthesis from rotating and obstructing the left ventricular outflow tract . Because conventional surgery had been declined for this patient, we tried to find an interventional solution.
To the best of our knowledge, this is the first case that demonstrates the feasibility of recapturing a balloon-expandable prosthesis after left ventricular embolization. Among various potential causes of such a complication,2 mild valve calcifications and a possible underestimation of the true annular size by TEE are the most likely. A multimodal annulus sizing with a computed tomography scan3 could have been helpful but was not included in our selection process at this time before balloon-expandable prosthesis implantation.

Open heart surgery is performed to treat cardiac disorders. The disorders may be linked to cardiac muscles, arteries or the valves of the heart. The heart is a vital organ thus, various complications are associated with open-heart surgery, which is associated with the heart or to other organs. The whole recovery from the open-heart surgery takes less time in younger patients as compared to the elderly.

What Are The Risks Of Open
The risk of post-surgical complications increases as people age or if their procedure is urgent or an emergency. Patients that have multiple medical problems can be at higher risk for some debilitating complications such as a stroke or kidney failure. Some people may experience transient memory loss and problems concentrating or thinking clearly after surgery. Other risks include:
- Bleeding
- Infection, fever, swelling and other signs of inflammation
- A reaction to the medicine used to make the patient sleep during the surgery
- Irregular heartbeats
- Damage to the tissues in the heart, kidneys, liver and lungs
- Stroke
Open Heart Surgery For Bioprosthetic Heart Valve Failure
Reoperation is a procedure widely considered to carry increased risk: the mortality rate is higher than for those undergoing first surgery, although some registries have found conflicting evidence.41,42 Data from the Society of Thoracic Surgeons database show an in-hospital mortality rate of 4.6% among 3380 patients who underwent repeat aortic valve replacement.43 This record represents the largest reported population and is an important reference for clinical outcomes of repeat surgery in the VIV era.
The group with bioprosthetic valves who underwent repeat open heart surgery included 2213 patients. The operative mortality rate was 4.7%, and the composite rate of operative mortality and major morbidity was 21.9%. Stroke was reported for 1.8% of patients, and a pacemaker was required in 11.5%. Selected high-volume centers achieved lower 30-day mortality rates of 2% to 3% after repeat surgery.4446 Surgical reoperation was the main therapeutic modalityfor patients with prosthetic valve stenosis and/or regurgitation before the era of transcatheter therapies. Repeat open heart surgery is becoming less common when the less invasive transcatheter VIV procedure is available.47

Open Heart Surgery Recovery Complications
Failure-to-rescue is the term used for the death of a patient due to complications following major surgery. Open-heart surgery is considered major surgery and has several complications. The surgery should be accomplished such that the risk of post-operative complications is kept at a minimum, however, the post-operative care also plays an important role in keeping at bay, the operative complexities. Open heart surgery is done to treat various abnormalities in the internal structure of the heart such as valves, heart muscle, aorta or vessels. Some conditions such as gastrointestinal complications and insomnia fade as the patient recover. Below are the various complications associated with open heart surgery:

Coronary Artery Bypass Graft Surgery
To sew the grafts onto the very small coronary arteries, your doctor will need to stop your heart temporarily. Tubes will be put into the heart so that your blood can be pumped through your body by a heart-lung bypass machine.
Once the blood has been diverted into the bypass machine for pumping, your doctor will stop the heart by injecting it with a cold solution.
When the heart has been stopped, the doctor will do the bypass graft procedure by sewing one end of a section of vein over a tiny opening made in the aorta, and the other end over a tiny opening made in the coronary artery just below the blockage. If your doctor uses the internal mammary artery inside your chest as a bypass graft, the lower end of the artery will be cut from inside the chest and sewn over an opening made in the coronary artery below the blockage.
You may need more than one bypass graft done, depending on how many blockages you have and where they are located. After all the grafts have been completed, the doctor will closely check them as blood runs through them to make sure they are working.
Once the bypass grafts have been checked, the doctor will let the blood circulating through the bypass machine back into your heart and he or she will remove the tubes to the machine. Your heart may restart on its own, or a mild electric shock may be used to restart it.
S/techniques Of Open Heart Surgery
The procedure commences with general anesthesia rendering the patient unconscious. An 8-10 inch incision is made on the patient’s chest. Another cut needs to made across breastbone of the patient for the heart to become clearer to the operating surgeon. A heart-lung bypass machine is connected to the patient’s body thereafter. The machine stops the heart from beating so that the surgeon can operate on it.
A machine simultaneously takes down blood from the heart which oxygenates the blood and puts it back into the body. A wire is placed in the breastbone and the original incision is stitched up. Open heart surgery is also possible without stopping the functioning of heart. That approach is termed as off pump.
