The Mount Sinai Department of Cardiovascular Surgery

Our Department of Cardiovascular Surgery has expertise in every major area of cardiac surgery, with surgeons performing procedures to correct a wide variety of congenital and acquired cardiac abnormalities in adults and children.

  • Mitral valve surgery
  • Heart transplantation
  • Mechanical assist devices
  • Aortic aneurysm surgery

As a tertiary referral center, Mount Sinai Heart has a reputation for taking on difficult cases. Complex ischemic and valvular cases are routine. Using the latest valve reconstruction techniques, our surgeons are often able to repair valves rather than replace them. For patients with mitral valve prolapse, our success rate in mitral valve repair approaches 100 percent.

Cardiovascular surgeons from Mount Sinai travel the world to perform cardiac surgery in children, bringing advanced technological developments to such nations as Russia, the People's Republic of China, and Vietnam as part of an academic exchange of information.

Procedures and Therapies for Complex Cases

As a referral center for complex cardiac cases, the Department of Cardiovascular Surgery encounters a full spectrum of congenital heart disorders. We perform many cardiac procedures, such as aortic valve replacement and mitral valve repair, using "minimally invasive" approaches. A rapidly growing part of this effort is off-pump coronary artery bypass. These less-invasive procedures reduce hospital costs, shorten length of stay, and offer patients a more-rapid and less-painful recovery.

While repair of atrial and ventricular septal defects is routinely accomplished using modified small sternotomy incisions, more-complex anatomical defects may require staged operations. In those cases, we can often avoid transfusion, even in small children. Advanced techniques allow for a shorter hospital stay and a speedier recovery.

Our fetal monitoring program facilitates coordination between pediatric cardiologists and cardiac surgeons, ensuring comprehensive care for newborns who may require surgical intervention shortly after birth. Extracorporeal membrane oxygenator support is available as an adjunct to other forms of ventricular support.


Cardiovascular surgeons at Mount Sinai take a special interest in complex thoracic aortic and thoracoabdominal aneurysm surgery. Our Cardiovascular Surgery Department maintains an extensive database of thoracic-aortic aneurysms not yet requiring surgery. Surgeons use the database to evaluate the natural history of aneurysms and determine the optimum time for surgical intervention. By studying the data, surgeons can calculate the probability of rupture and perform surgery at the most opportune time.

Congestive Heart Failure

Our cardiovascular surgeons have expertise in surgical options for patients with intractable congestive heart failure. Despite severe ventricular dysfunction, patients with congestive heart failure who have a substantial amount of viable myocardium may benefit from coronary bypass surgery.

When mitral valve disease is the primary cause of cardiac failure, valve repair may bring about symptomatic and functional improvement. Cardiac replacement, either through transplantation or a ventricular assist device, is an alternative for select patients when there are no other options.


More than 200 heart transplants have taken place at Mount Sinai, with about 25 to 30 performed each year. The survival rate for patients undergoing heart transplantation at Mount Sinai is among the best in the nation. When appropriate, left ventricular assist devices (LVADs) can provide a crucial "bridge" to transplantation. LVADs may provide a long-term solution for patients not otherwise suited for transplantation.
