Cardiac Surgery Division
About
The Division of Cardiac Surgery at the University of Virginia has an outstanding national reputation for performing high volume and high quality cardiac surgery. Annually, we perform over 1,300 procedures – among the highest in both the Southeastern U.S. and mid-Atlantic region of the U.S. We perform the full breadth of cardiac surgery from healthy patients with valve and coronary artery disease to complex redo surgery, often utilizing innovative and less invasive approaches. Many of our patients are referred to UVA because they have been turned down by other centers. Our specialized team includes surgeons, cardiologists, specialty trained ICU physicians and Magnet awarded nursing staff. UVA has been ranked the #1 hospital in Virginia for four straight years.
Today, our cardiac surgery team performs a diverse array of complex operations, which is one of the reasons UVA is ranked as one of the best medical centers in Virginia and the southeastern U.S. Our innovative spirit and collaborative team effort with our cardiology team is demonstrated in our effort to continue to push the frontier with new, minimally invasive procedures while also continuing to sustain and improve traditional open heart surgery, such as bypass and heart transplants.

Clinical Programs
UVA cardiac surgeons have developed national reputation in all types of cardiac surgery. Our surgeons focus on high quality outcomes and on caring for patients and their families with compassion as they heal.
The Advanced Cardiac Valve Center formally started in 2008 when UVA was the first in Virginia to start performing transcatheter aortic valve replacement (TAVR). Long before that, UVA cardiac surgeons were known in the region as the go-to specialists for valve surgery. Over the last 10 years, UVA cardiac surgeons and cardiologists work closely together to create a personalized approach for every patient. This allows the best possible outcome. UVA has gained international recognition for our Valve Center with a focus on performing complex high risk cases, innovative minimally invasive procedures, and a number of novel transcatheter trials.
The Minimally Invasive Valve Program began in 2012. Currently, both low and high risk patients are eligible to get their valve surgery through less invasive incisions that don’t break the breast bone. In addition, UVA has many novel clinical trials related to valve disease, often being the first to perform procedures in the U.S. Patients often travel from significant distances to be evaluated for less invasive and novel clinical trials. Our aortic valve and mitral valve outcomes have some of the best outcomes in the region, commonly receiving 3 stars (top STS rating) for low mortality and complications.
UVA’s Advanced Heart Failure and Transplant Program is recognized for its expertise throughout the region. UVA has received numerous awards and recognition from the American Heart Association and U.S. News & World Report for outstanding treatment of heart failure. Surgeons and cardiologists with decades of experience lead specialized teams who only focus on treating patients with severe heart failure. UVA’s ventricular assist device (LVAD) program has the most advanced VADs available and participates in numerous clinical trials offering cutting edge therapies. In fact, our LVAD and Transplant program has received numerous accolades for our volume, outcomes, and patient satisfaction scores.
In addition to our heart failure program, UVA’s ECMO team is the only one in Virginia named a Center of Excellence with Gold Status from the Extracorporeal Life Support Organization. In extreme cases of cardiopulmonary failure, UVA can support patients with a special life support machine to act as your heart and lungs and pump blood to the body and vital organs. UVA has developed an ECMO transport system to bring patients who need ECMO to UVA urgently as well as expertise in definitive therapies beyond ECMO which may include LVADs and heart transplantation.
Coronary artery disease remains one of the leading causes of death in Virginia. UVA has long employed a heart team approach to treat patients with complex coronary artery disease combining the expertise of cardiologists and surgeons who specialize in fixing blocked coronary arteries. UVA has received the highest possible rating from the U.S. News & World Report in heart bypass surgery. UVA surgeons can perform standard open CABG procedures often using multiple arteries to perform bypass surgery as well as minimally invasive CABG through without breaking the breast bone. In addition, UVA has been a leader in numerous NIH and industry sponsored trials and is the only in Virginia to offer cutting edge technologies to patients undergoing CABG surgery including hybrid coronary revascularization (combining stents with minimally invasive CABG), and using a special external wrap to help vein bypasses last longer.
UVA has long been a major referral center across the state and region for treating patients with complex aortic disease. Recently UVA has created a comprehensive Complex Aortic Disease Center. Our center provides the full array of treatments to patients with aortic disease including percutaneous endografting, complex open surgery, and hybrid approaches combining the two. UVA has access to many of the cutting edge trials and therapies that are in development, giving patients options that they may not have had before. Furthermore, UVA surgeons have developed many techniques over the years that have been employed by other surgeons across the world. Cardiac surgeons, vascular surgeons, cardiologists, and interventional radiologists all work collaboratively at UVA to provide the best care possible to treat aortic diseases, including congenital and acquired aortic diseases.
Atrial fibrillation is the most common arrhythmia and can result in stroke and death. UVA provides comprehensive care for all aspects of atrial fibrillation. The cardiac surgeons work closely with the cardiologists to tailor a personalized treatment plan for each patient. In some cases this is a catheter-based ablation while in others it is a surgical ablation in conjunction with other cardiac surgery. In some cases a hybrid approach is used with a minimally-invasive surgical ablation followed by catheter-based ablation. UVA cardiac surgeons have extensive experience with surgery to ligate the left atrial appendage, dramatically reducing the risk of stroke. Furthermore, our surgeons were the leaders in placing a novel clip to ligate the appendage that led to FDA approval.

Learn MoreInnovation
The department of Surgery at UVA developed a Surgical Innovation Center in 2016. Since then, we have developed, disclosed, and patented dozens of medical devices and concepts. The Innovation Center is a partnership between our department and the Department of Biomedical Engineering, the Darden School of Business, and UVA’s License and Ventures Group. UVA cardiac surgeons have been leading these efforts with several devices in development. Below are just a couple of the ideas that have been developed.
Our team of cardiac surgeons and engineers has developed a novel intraventricular stent (VADstent) to prevent suction events and attenuate adverse RV remodeling in patients with continuous flow ventricular assist devices (VAD). The VADstent is deployed during implantation of the inflow cannula and stents the left ventricle open to prevent collapse, keep the septum midline, and align the cannula with the mitral valve. We performed proof of concept studies in swine and ovine models. The VADstent was able to prevent suction events and maintain the geometry of the left ventricle. Importantly, no ventricular arrhythmias, hemolysis, mitral valve injury or other adverse events were noted during these experiments. Currently we have updated our prototype based on previous results and are ready to move into a long-term animal model to assess durability prior to first in human studies.
UVA cardiac surgeons have patented and developed a novel laparoscopic port that allows surgeons to cauterize any bleeding from the abdominal or chest wall by using the port itself. In collaboration with the School of Engineering, early prototypes have been developed and proven effective in early animal studies.
Cardiac Research
All members of the Division of Cardiac Surgery engage in innovative research ranging from novel clinical trials to clinical outcomes research to innovative translational research. Cardiac surgeons are principal investigators or co-investigators on dozens of clinical trials related to valve disease, coronary artery disease, renal failure after heart surgery, aortic diseases, and heart failure surgery. Collectively, our group publishes more than 75 new publications each year. The division has two basic science labs. Finally, we have a robust clinical outcomes research group that partners with the Virginia State Cardiac Services Quality Initiative (VCSQI).
For over two decades, the Kron/Laubach lab has been investigating lung injury as it pertains to ischemia/reperfusion, during lung transplantation, and during cardiopulmonary bypass. Dr. Roeser’s research focuses on innovative technologies to treat ARDS and burn injuries. Dr. Teman’s research interests are in the detection and prevention of organ damage related to cardiopulmonary bypass (the “heart-lung machine”). Collectively, this lab has had numerous grants from the NIH, DOD, and American Heart Association.
Our team at UVA has been highly prolific in investigations that strive for the best possible outcome. Whether it is deciding on which patients benefit the most from an operation, or risk factors for specific complications, our surgeons are constantly trying to provide the best possible care based on up-to-date knowledge. We also work closely with and serve leadership positions in the Virginia Cardiac Surgery Quality Initiation (VCSQI) the largest regional clinical outcomes collaborative in the U.S. targeted at improving cardiac outcomes.
