Cardiothoracic Surgery and Cardiac Surgery: A Patient Guide

Conditions Treated by Cardiothoracic and Cardiac Surgeons

• Coronary artery disease: Coronary artery disease happens when the blood vessels supplying the heart become narrowed or blocked. This can cause chest pain, breathlessness, reduced exercise ability or heart attacks. A cardiac surgeon may be asked to consider coronary artery bypass grafting when medicines, lifestyle changes or stents are not enough, or when the pattern of blockages makes surgery a strong option.

• Heart valve disease: The heart has four valves that keep blood moving in the right direction. A valve can become narrowed, called stenosis, or leaky, called regurgitation. Surgeons may repair or replace valves such as the aortic, mitral or tricuspid valve when the disease is severe enough to affect symptoms, heart function or future risk.

• Aortic aneurysm and aortic dissection: The aorta is the main artery carrying blood from the heart to the body. An aneurysm is a swelling of the aorta, while a dissection is a tear in the wall of the aorta. These conditions can be serious because the aorta is under high pressure, so specialist assessment is important when surgery or careful monitoring is being considered.

• Adult congenital heart disease: Some people are born with heart problems that continue into adult life or need further treatment years after childhood surgery. These may include holes in the heart, abnormal valves or complex changes in the way blood flows through the heart. Adult congenital heart surgery is usually planned by a specialist team with experience in these conditions.

• Heart failure and advanced heart disease: Heart failure means the heart is not pumping as well as the body needs. Surgery may be considered if there is a correctable cause, such as valve disease or blocked arteries. In advanced cases, a patient may be assessed for a ventricular assist device, transplant, or other specialist support.

• Atrial fibrillation and other rhythm problems: Atrial fibrillation, often called AF, is an irregular heart rhythm. Many rhythm problems are managed by cardiologists, but surgeons may treat AF during another heart operation or through a procedure such as surgical ablation. The aim is to reduce abnormal electrical signals that disturb the heartbeat.

• Infective endocarditis: Endocarditis is an infection of the heart lining or valves. It can damage valves, cause leaks, or lead to serious complications if infection spreads or does not clear with antibiotics. Surgery may be needed when valve damage is severe, infection persists, or there is a risk of dangerous fragments breaking away.

• Pericardial disease: The pericardium is the thin sac around the heart. It can become inflamed, thickened or stiff, making it harder for the heart to fill properly. A cardiac surgeon may perform procedures to drain fluid or remove part of the pericardium when symptoms and tests suggest surgery is needed.

• Cardiac tumours and masses: Tumours in the heart are rare, but some can block blood flow, interfere with valves or increase the risk of stroke. A common example is a myxoma, which is often benign but may still need removal. A specialist team will usually review imaging before deciding the safest approach.

• Lung cancer and lung nodules: Thoracic surgeons, who are part of the cardiothoracic family, often treat lung cancer and suspicious lung nodules. Surgery may remove a small wedge of lung, a larger lobe, or rarely an entire lung. The decision depends on the cancer stage, lung function and the patient’s overall fitness.

• Pleural disease, collapsed lung and chest infection: The pleura is the lining around the lungs. Problems such as recurrent fluid build-up, pneumothorax, empyema or pleural thickening may need thoracic surgery. Treatment may involve keyhole surgery, drainage, removal of infected tissue or procedures to help the lung stay expanded.

• Oesophageal and chest wall conditions: Some cardiothoracic surgeons treat conditions affecting the oesophagus, including cancer, swallowing problems or reflux-related complications. They may also help with chest wall deformities, trauma, rib problems or tumours. These areas are usually managed by surgeons with specific thoracic expertise.

Common Cardiothoracic and Cardiac Surgery Procedures

• Coronary artery bypass grafting (CABG): CABG, often called heart bypass surgery, creates a new route for blood to flow around narrowed or blocked coronary arteries. A surgeon usually uses a blood vessel from the chest, arm or leg to make the bypass. It is done to improve blood supply to the heart muscle, relieve angina and, in selected patients, improve long-term outcomes.

• Aortic valve replacement: Aortic valve replacement treats a badly narrowed or leaking aortic valve. The damaged valve is replaced with a mechanical valve or a tissue valve. The best choice depends on age, lifestyle, bleeding risk, need for blood-thinning medicine and future treatment options.

• Aortic valve repair: Some aortic valves can be repaired rather than replaced, especially in selected patients with leaking valves or aortic root problems. Repair may preserve the patient’s own valve and avoid some issues linked to replacement valves. It is a specialist operation and suitability depends on valve anatomy and surgeon experience.

• Mitral valve repair: Mitral valve repair is commonly used for mitral regurgitation, where blood leaks backwards inside the heart. Surgeons may reshape the valve, repair supporting chords, or use a ring to support the valve. When suitable, repair may preserve the natural valve and support good heart function.

• Mitral valve replacement: If the mitral valve is too damaged to repair reliably, it may be replaced with a mechanical or tissue valve. This may be needed in severe valve narrowing, heavy calcification, infection or complex valve damage. The surgeon should explain why replacement is preferred over repair in your case.

• Aortic root and ascending aorta surgery: This surgery treats swelling or disease in the first part of the aorta as it leaves the heart. It may involve replacing part of the aorta with a graft and sometimes repairing or replacing the aortic valve. It is considered when the risk of leaving the aorta untreated becomes greater than the risk of surgery.

• Surgery for atrial fibrillation, including Maze or surgical ablation: During AF surgery, the surgeon creates controlled lines of scar tissue to interrupt abnormal electrical signals. This may be done during valve or bypass surgery, or in selected cases as a planned rhythm procedure. Some patients may also have the left atrial appendage closed to reduce stroke-related risk, depending on their circumstances.

• Minimally invasive or keyhole heart surgery: Some heart operations can be performed through smaller cuts between the ribs rather than a full breastbone opening. This may reduce wound size and support recovery in suitable patients, but it is not the best option for everyone. Safety, anatomy and the surgeon’s experience matter more than incision size.

• Transcatheter valve procedures, including TAVI: TAVI stands for transcatheter aortic valve implantation. It is usually performed by a heart team and often led by interventional cardiologists, with cardiac surgeons involved in assessment and planning. It may be considered for patients with aortic stenosis, especially when open surgery carries higher risk or a catheter-based option is more suitable.

• Heart transplant: A heart transplant replaces a failing heart with a donor heart. It is considered only for selected patients with advanced heart failure when other treatments are no longer enough. Assessment is detailed and includes physical health, other medical conditions, emotional readiness, support at home and long-term medicine needs.

• Ventricular assist device (VAD) surgery: A VAD is a mechanical pump that helps a weak heart move blood around the body. It may be used while waiting for a transplant or as longer-term support in some patients. This is specialist surgery that requires careful follow-up, education and a strong support system.

• Pericardiectomy and pericardial window: A pericardiectomy removes part or most of a stiff pericardium when it restricts heart filling. A pericardial window helps drain fluid from around the heart and reduce the chance of it coming back. These procedures are considered when fluid or scarring affects heart function or causes significant symptoms.

• Lung resection, including wedge resection, segmentectomy and lobectomy: Thoracic surgeons may remove part of the lung to treat lung cancer, some infections or suspicious nodules. A lobectomy removes one lobe of the lung, while smaller resections remove less tissue. The team will usually assess breathing tests, scans and overall fitness before surgery.

• Video-assisted or robotic thoracic surgery (VATS/RATS): VATS and robotic thoracic surgery use small cuts and a camera to operate inside the chest. They are commonly used for some lung and pleural operations. These approaches may reduce pain and recovery time for some patients, but suitability depends on the condition, anatomy and local expertise.

When to See a Cardiothoracic or Cardiac Surgeon

What to Expect at Your First Cardiothoracic Surgery Appointment

Suggested Questions to Ask Your Cardiothoracic or Cardiac Surgeon

1. What exactly is my diagnosis, and how severe is it?

   Why you should ask this: This helps you understand whether the problem is mild, moderate or severe, and whether surgery is urgent, planned or only one possible option.

2. What are all my treatment options, including no surgery for now?

   Why you should ask this: Patients often assume there is only one route. Asking this helps compare surgery, medicines, monitoring, catheter-based procedures and lifestyle changes where relevant.

3. Why are you recommending this operation for me specifically?

   Why you should ask this: This moves the conversation from generic information to your own anatomy, symptoms, test results, risk level and personal goals.

4. How many of these procedures does this hospital or surgeon perform, and what outcomes are measured?

   Why you should ask this: Experience and outcomes matter. You are not asking for a guarantee; you are asking how the team tracks safety, complications, survival, repair rates, recovery and patient experience.

5. What will recovery look like for someone with my health and lifestyle?

   Why you should ask this: Recovery is not just a hospital event. Ask about pain, driving, lifting, work, sex, exercise, cardiac rehabilitation, family support and warning signs after discharge.

6. What are the main risks I should understand before giving consent?

   Why you should ask this: Every procedure has risks. Ask about the risks that are most relevant to you, including stroke, bleeding, infection, kidney problems, rhythm issues, repeat surgery and long-term medication.

7. What should I do now to prepare for the best possible outcome?

   Why you should ask this: This may include stopping smoking, dental checks before valve surgery, improving fitness, reviewing medicines, managing diabetes, arranging help at home, and writing down your priorities.
