Background & Scope

Cardiac anesthesiology is a subspecialty of anesthesiology that focuses on the care of patients undergoing cardiothoracic surgery and other procedures involving the heart and lungs. Cardiac anesthesiologists are medical doctors who are trained in the administration of anesthesia and the management of patients before, during, and after cardiac surgery.

The scope of cardiac anesthesiology includes preoperative evaluation and preparation of patients, intraoperative management of hemodynamics and other vital functions, and postoperative care of patients in the intensive care unit (ICU), cardiothoracic intensive care unit (CTICU), or recovery room. Cardiac anesthesiologists work closely with cardiothoracic surgeons, cardiologists, and other members of the surgical team to ensure the safe and effective care of patients.

One of the primary responsibilities of a cardiac anesthesiologist is to manage the administration of anesthesia during surgery. This involves selecting the appropriate anesthetic agents and monitoring the patient's vital signs and level of consciousness during the procedure. Cardiac anesthesiologists also maintain the patient's blood pressure and oxygen levels and manage any complications that may arise during surgery, including coding.

In addition to administering anesthesia, cardiac anesthesiologists also play a key role in the preoperative evaluation of patients. This includes reviewing the patient's medical history, conducting a physical examination, and ordering any necessary diagnostic tests. Cardiac anesthesiologists also work with patients to develop a personalized plan for their care, including any necessary preoperative instructions or medications.

After surgery, cardiac anesthesiologists provide postoperative care to patients in the ICU, CTICU, or recovery room. This includes monitoring the patient's vital signs and administering medications to manage pain and other postoperative complications. Cardiac anesthesiologists also work with the surgical team to develop a plan for the patient's ongoing care, including any necessary follow-up appointments or rehabilitation.

Overall, the role of a cardiac anesthesiologist is to provide comprehensive, patient-centered care to individuals undergoing cardiothoracic surgery and other procedures involving the heart and lungs.

Qualifications, Training, and Certifications

Cardiac anesthesiology is a highly specialized field within the field of anesthesiology requiring additional qualifications and training. To become a cardiac anesthesiologist, a physician must complete a residency program in anesthesiology (typically four years), which includes the administration of anesthesia, pain management, critical care, and the management of medical emergencies. That is followed by further training, most typically a fellowship in cardiac anesthesiology. These programs typically last one to two years and provide advanced training in the care of patients undergoing cardiothoracic surgery and other procedures involving the heart and lungs. Fellowships in cardiac anesthesiology may also include training in echocardiography (for which there is separate certification available), invasive hemodynamic monitoring, and the management of complex medical conditions.

Upon completion of a fellowship in cardiac anesthesiology, individuals are eligible to take the certification examination offered by the American Board of Anesthesiology (ABA). Passing this exam allows a physician to become certified in the subspecialty of cardiac anesthesiology.

In addition to the ABA certification, individuals may also choose to obtain certification in advanced cardiac life support (ACLS) or the Certification for Advanced Perioperative Transesophageal Echocardiography (PTEeXAM). These certifications demonstrate a level of expertise in specific areas of cardiac anesthesiology and may be required for certain job positions or advancement opportunities.

Conditions, Diseases, Treatments, and Procedures

Cardiac anesthesiologists are trained to diagnose and treat a wide range of conditions, diseases, and injuries, including:

• Coronary artery disease: This is a condition in which the arteries that supply blood to the heart become narrowed or blocked, reducing the flow of oxygen-rich blood to the heart muscle. Cardiac anesthesiologists may be involved in the care of patients undergoing coronary artery bypass surgery, in which a healthy blood vessel is taken from another part of the body and used to bypass the blocked artery.

• Heart valve disorders: These conditions involve problems with the heart's valves, which regulate the flow of blood through the heart. Cardiac anesthesiologists may be involved in the care of patients undergoing heart valve surgery, which involves repairing or replacing damaged valves.

• Cardiomyopathy: This is a group of diseases that affect the heart muscle, making it difficult for the heart to pump blood effectively. Cardiac anesthesiologists may be involved in the care of patients undergoing surgery to treat cardiomyopathy, such as heart transplantation.

• Heart failure: This is a condition in which the heart is unable to pump enough blood to meet the body's needs. Cardiac anesthesiologists may be involved in the care of patients undergoing surgery to treat heart failure, such as implantation of a left ventricular assist device (LVAD).

• Cardiac arrhythmias: These are abnormal heart rhythms. Cardiac anesthesiologists may be involved in the care of patients undergoing procedures to treat cardiac arrhythmias, such as catheter ablation or implantation of a pacemaker or defibrillator.

In addition to these diagnoses and treatments, cardiac anesthesiologists may also be involved in the care of patients with other conditions, injuries, or diseases that require cardiothoracic surgery or other procedures involving the heart and lungs. These may include aortic aneurysms, congenital heart defects, and lung cancer.

As part of their role, cardiac anesthesiologists perform a variety of procedures, including:

• Administering anesthesia: Cardiac anesthesiologists are responsible for selecting the appropriate anesthetic agents and monitoring the patient's vital signs and level of consciousness during surgery.

• Monitoring hemodynamics: Cardiac anesthesiologists use a variety of techniques to monitor the patient's blood pressure, heart rate, and other vital functions during surgery.

• Managing complications: Cardiac anesthesiologists are trained to recognize and manage any complications that may arise during surgery, such as bleeding or allergic reactions. This is the physician who will be primarily responsible for saving the patient if they code.

• Providing postoperative care: After surgery, cardiac anesthesiologists provide care to patients in the ICU, CTICU, or recovery room, monitoring their vital signs and administering medications to manage pain and other postoperative complications.

Related Specialties

Cardiac anesthesiology is a subspecialty of anesthesiology that focuses on the care of patients undergoing cardiothoracic surgery and other procedures involving the heart and lungs. As such, cardiac anesthesiology is closely related to a number of other medical specialties, including:

• Cardiology: Cardiology is a medical specialty that focuses on the diagnosis, medical treatment, and management of conditions and diseases of the heart and blood vessels. Cardiologists work closely with cardiac anesthesiologists to manage the care of patients undergoing cardiothoracic surgery and other procedures involving the heart and lungs.

• Cardiothoracic surgery: This is a surgical specialty that focuses on the surgical treatment of diseases and conditions of the heart, lungs, and chest. Cardiac anesthesiologists work closely with cardiothoracic surgeons to provide anesthesia and perioperative care to patients undergoing these procedures.

• Critical care medicine: This is a medical specialty that focuses on the care of critically ill patients, including those in the ICU and CTICU. Cardiac anesthesiologists may work with intensivists to provide care to patients in the ICU or CTICU after cardiothoracic surgery or other procedures involving the heart and lungs.

Medical-Legal Cases Involving Cardiac Anesthesiology

Cardiac anesthesiology is a complex and highly specialized field, and like all medical specialties, it is not immune to medical-legal cases. Medical-legal cases involving cardiac anesthesiology may arise for a variety of reasons, including:

• Adverse events: Adverse events, such as complications or adverse reactions to medication, can occur during or after cardiothoracic surgery or other procedures involving the heart and lungs. If an adverse event is believed to have been caused by medical negligence or error, it may lead to a medical-legal case.

• Miscommunication: Miscommunication or a breakdown in communication between members of the surgical team, including the cardiac anesthesiologist, can lead to medical-legal cases. This includes the nursing staff, the surgeon, and the perfusionist. For example, if a patient's medical history or allergies may not have been properly communicated or documented.

• Failure to obtain informed consent: Before any surgical procedure, it is important for the patient to fully understand the risks and benefits of the procedure and to give their informed consent.

• Misuse of equipment: If a cardiac anesthesiologist may not have properly used or maintained medical equipment, e.g., if anesthesia machine is not properly calibrated or if sterilization procedures are not followed.

• Failure to follow protocols: Cardiac anesthesiologists are expected to follow established protocols and guidelines when caring for patients.
