Robotic Heart Surgery

Weill Cornell Medicine uses the latest advancement in minimally invasive cardiac procedures: robotic heart surgery. Combining smooth and dexterous robotic instruments with a high-definition 3D camera, our surgeons are able to perform procedures through tiny incisions with a precision that would be impossible with just their hands. Robotic heart surgery replaces a traditional sternotomy, which involves splitting the breastplate with a saw. The robotic method means minimal trauma, less blood loss and less overall discomfort for the patient.

Endoscopic Robotic Mitral Valve Repair

Robotic mitral valve repair is one of our more common procedures. The mitral valve sometimes can leak blood backward into the left atrium. This is mitral valve regurgitation which is often caused by mitral valve prolapse. Another condition, mitral valve stenosis is when the valve becomes narrow or restrictive which can cause blood to back up into the atrium and lungs.

The robotic method is most often used to repair the mitral valve but if replacement is required due to extensive damage to the valve, a replacement can also be performed with the robot.

About Dr. Guy and the Robotic Heart Surgery Team

Dr. Guy has more than 14 years of experience mastering robotic heart surgery. He strives to find the least invasive method for the comfort and safety of his patients. His dedicated team was carefully selected based on their experience and skills, and their ability to support the mission of putting the patient’s needs first.

The Robotic Heart Surgery Team currently specializes in the following procedures:

  • Mitral valve repair
  • Mitral valve replacement
  • MAZE procedure (to treat atrial fibrillation)
  • Atrial septal defect closure
  • Removal of cardiac tumors (atrial myoxoma)
  • Septal myectomy for hypertrophic obstructive cardiomyopathy (HOCM or HCM)
  • Tricuspid valve repair or replacement
  • Coronary artery bypass (for blocked arteries to the heart)
  • Pacemaker lead placement (for heart failure)
