Cardiovascular and Thoracic Surgery in Las Vegas, NV

St. Rose | Stanford Clinic's cardiovascular and thoracic surgery program brings Stanford physicians to the Las Vegas Valley in a collaboration with St. Rose Dominican.

The team of Las Vegas cardiologists at the clinics are advancing the science of cardiovascular and thoracic surgery in the Las Vegas Valley, which means the rate of post-surgical complications will decrease while patient survival rates increase. The program brings leading-edge technology to cardiothoracic surgery in Las Vegas and Henderson, including new types of hybrid cardiac/cardiovascular surgery procedures.

The St. Rose | Stanford affiliation maintains the independence of both medical centers while providing an infrastructure that fosters partnership and collaboration among staff at both institutions. By joining forces, Dignity Health - St. Rose Dominican and Stanford now provide academic-based care in southern Nevada in these Stanford satellite clinics.

Advanced Cardiovascular and Thoracic Surgery Treatments at the St. Rose | Stanford Clinic

The St. Rose | Stanford Clinic combines the expertise and compassion of our Las Vegas heart specialists with the nationally renowned experts at Stanford to bring an unprecedented level of care to you. Our goals are to:

  • Provide university-affiliated medical care close to home
  • Offer more minimally-invasive treatments

Advanced treatments the Clinic provides include:

  • "Beating heart" surgery, a less invasive type of heart surgery that does not require the use of a heart-lung bypass machine. Our team uses this procedure to treat a wide range of heart conditions, from atrial fibrillation and valve repair to congenital heart defects and coronary artery disease.
  • Minimally invasive cardiac and thoracic surgeries, surgical techniques that result in less pain and a shorter recovery
  • Transmyocardial laser revascularization, a treatment that improves blood flow to the heart in patients with inoperable heart conditions (including severe angina and coronary artery disease)
  • Maze procedure for atrial fibrillation, a complex procedure to stop erratic heart rhythms
  • Robotic-assisted cardiac surgery, using the da Vinci® Si Surgical System, a robotic surgical system we use to perform mitral valve surgeries at our St. Rose Dominican, San Martín Campus.

Benefits of Minimally-Invasive Heart Surgery

Minimally-invasive heart surgery techniques, such as robotic-assisted surgery for mitral valve repairs, require smaller incisions and less manipulation of healthy tissue. This means less pain and a faster recovery.

Other benefits of minimally-invasive surgery include:

  • More precise surgery
  • Less blood loss
  • Less scarring
  • Shorter hospital stay
