What is Cardiothoracic Surgery?
Cardiothoracic surgery is a specialized field of medicine that focuses on the surgical treatment of conditions affecting the heart, lungs, esophagus, and other organs within the chest. This includes procedures such as coronary artery bypass grafting (CABG), heart valve repair or replacement, lung resections, and surgeries for congenital heart defects. Cardiothoracic surgeons are highly trained to manage both routine and complex cases, often addressing life-threatening conditions like heart disease, lung cancer, and thoracic trauma. The field requires not only technical precision and advanced surgical skills but also a deep understanding of cardiovascular and respiratory physiology. Through innovative techniques, such as minimally invasive surgery and robotic-assisted procedures, cardiothoracic surgeons aim to improve patient outcomes and enhance recovery.
The Role of a Cardiothoracic Surgeon
Cardiothoracic surgeons are responsible for diagnosing and managing a wide range of cardiac conditions and thoracic conditions. Their role extends beyond surgery to include pre-operative assessments, post-operative care, and ongoing patient management. They work closely with other healthcare professionals, including cardiologists, anesthesiologists, and nurses, to provide comprehensive care.
Cardiac Diseases
Cardiothoracic surgeons frequently operate on a variety of cardiac conditions, many of which are life-threatening and require surgical procedures to restore heart function. Common conditions include coronary artery disease, where blocked arteries necessitate procedures like coronary artery bypass grafting (CABG) to improve blood flow to the heart. They also treat heart valve disorders, such as aortic stenosis or mitral regurgitation, which may require valve repair or replacement to ensure proper blood flow through the heart. Congenital heart defects, including atrial septal defects or tetralogy of Fallot, are often corrected through specialized surgeries. Additionally, cardiothoracic surgeons manage aortic aneurysms and aortic dissections, which involve the repair or replacement of weakened sections of the aorta to prevent rupture. Advanced heart failure and arrhythmias may lead to interventions such as heart transplantation or the implantation of ventricular assist devices (VADs). These procedures aim to restore cardiac function and improve the patient’s quality of life.
Many cardiothoracic surgeons now conduct minimally invasive surgical techniques including endovascular surgery. Endovascular surgery is a minimally invasive surgical technique used to treat vascular conditions from within the blood vessels. Rather than making large incisions, surgeons use catheters, guidewires, and imaging technologies to navigate through the vascular system and perform procedures. Commonly treated conditions include aortic aneurysms, arterial blockages, and vascular malformations. Techniques such as stent placement, angioplasty, and embolization are used to restore blood flow or repair damaged vessels. The minimally invasive nature of endovascular surgery often results in shorter recovery times, reduced pain, and lower risks of complications compared to traditional open surgery.
Thoracic Diseases
Cardiothoracic surgeons address a range of thoracic conditions involving the lungs, esophagus, and chest wall. One of the most common conditions is lung cancer, which often requires lung resections such as lobectomy or pneumonectomy to remove cancerous tissue. They also treat benign and malignant esophageal disorders, including esophageal cancer and achalasia, through thouracic surgery procedures like esophagectomy or esophageal myotomy. Other thoracic conditions include mediastinal tumors, which are growths in the central chest cavity, and pleural diseases like pleural effusions or mesothelioma, which may require pleurectomy or decortication. Cardiothoracic surgeons also conduct thoracic surgery and manage chest trauma, repairing rib fractures or lung injuries, and thoracic aortic aneurysms, involving the repair of weakened sections of the aorta in the chest during thoracic surgery. Through these thoracic surgery interventions, they aim to improve respiratory function, alleviate symptoms, and enhance the overall health and quality of life for patients.

How Long Is Cardiothoracic Surgery Residency - Structure of Cardiothoracic Surgery Residency
So how long is cardiothoracic surgery residency in the United States? The length to become a cardiothoracic surgeon depends on the pathway you take, taking at least 7 years. There are 3 main pathways to pursue cardiothoracic surgery:
The training pathway for cardiothoracic surgeons consists of two main components: general surgery residency and cardiothoracic surgery fellowship.
- Traditional Pathway (General Surgery + Cardiothoracic Surgery Fellowship)
In this pathway, residents first complete a five-year general surgery residency followed by a two- to three-year fellowship in cardiothoracic surgery. This approach allows for a broad foundation in general surgical principles before specializing in heart and thoracic procedures. In general surgery residency, surgical residents will do a lot of general surgery procedures, operating on other parts of the body including the gastrointestinal tract. Then, in cardiothoracic surgical fellowship, fellows will solely focus on aortic surgery, cardiac surgery, and thoracic surgery. - Integrated Cardiothoracic Surgery Residency (I-6 Program)
The integrated pathway, also known as the I-6 program, is a six-year residency that combines general surgery and cardiothoracic training from the start. This streamlined approach eliminates the need for a separate general surgery residency, allowing residents to focus on cardiothoracic surgery earlier in their training. This pathway is ideal for those committed to cardiothoracic surgery from the outset of their medical career. - 4+3 Combined Thoracic Surgery Residency Program
This hybrid model involves four years of general surgery residency followed by three years of specialized cardiothoracic surgery training. It provides a balance between the traditional and integrated pathways, allowing for significant general surgery experience while prioritizing early exposure to cardiothoracic techniques.
Regardless of the pathway, residents prepare for the American Board of Thoracic Surgery (ABTS). Residents should look for programs that provide them enough surgical procedure experiences to not only gain surgical skills leading to eligibility for the American Board of Thoracic, but to make them extremely comfortable to operate on complex thoracic surgical cases and complex cardiac surgical cases for their entire careers!
