Anesthesia And Cardiovascular Services

There was a time when the cardiovascular anesthesiologists were the top earners and the key leaders of so many anesthesia groups. Over time, however, two things happened: first, falling Medicare payment rates reduced the value of anesthesia for bypass surgery dramatically; and, second, hospitals started spending millions of dollars on cardiac catheterization (hereinafter, “cath”) labs and associated technology.

A Growing Line of Business

Last year, over a million cardiac catheterizations were performed in the United States, such that many hospitals were performing more than 500 procedures per year. Because these invasive procedures require some form of sedation, this has become a new line of business for anesthesia practices. As the number of coronary artery bypass graft (CABG) procedures has decreased, the number of cath lab procedures has increased. As anesthesia practices focus on and refine their strategic plans for the future, it is critical that they focus on the services their hospitals are investing in.

Hospitals are heavily investing in cath labs to enhance cardiac care, with recent projects ranging from $1.1 million for new equipment to over $12 million for advanced, comprehensive facilities. These investments focus on upgrading imaging technology, expanding structural heart procedures and increasing diagnostic capabilities—often using high-tech systems like the Philips Azurion. 

Over one million cardiac catheterization procedures are performed annually in the U.S., across nearly 2,000 labs. Individual hospital volumes vary widely based on size. Typical high-volume centers perform over 500 cases per year, while others may range from 650 to over 4,000 annual cases, depending on specialization. 

A Closer Look at the Technology

Cath lab services involve specialized, minimally invasive, imaging-guided procedures to diagnose and treat cardiovascular disease—including coronary artery disease, heart valve issues and arrhythmias. Key services include angioplasty and stenting, diagnostic coronary angiograms, electrophysiology studies/ablations, as well as structural heart repairs, like transcatheter aortic valve replacement (TAVR). A TAVR is a minimally invasive procedure for treating severe aortic stenosis by replacing a narrowed valve with a new one via a catheter, usually through the groin. It offers faster recovery, shorter hospital stays, and less pain compared to open-heart surgery, often taking under two hours. 

Anesthesia for hospital cath labs involves specialized care ranging from conscious sedation to monitored anesthesia care (MAC) or even general anesthesia for complex, high-risk and increasingly interventional procedures. The anesthesia mode is tailored to patient risk and procedure complexity (e.g., PCI, structural heart repairs). While many diagnostic cases use moderate sedation, specialized anesthesia teams are essential for hemodynamically unstable patients, long procedures or airway management.  It requires dedicated anesthesiologists to manage hemodynamics and radiation safety, frequently using short-acting agents, like propofol or remifentanil, for rapid turnover. 

Because of the growth in cath lab cases made possible by new technologies, more anesthesia resources will need to be devoted to this line of business.
