Repairing, Restoring, or Replacing Heart and Lung Function

Advanced heart and lung care requires a medical team dedicated to caring for people in some of life's most trying circumstances. Our board-certified cardiothoracic surgeons and specially trained medical professionals and staff work closely with patients, their families and their physicians to diagnose and treat diseases and conditions of the heart and lung.

Philosophy of Care

Advanced cardiothoracic care should not just be about what is offered, but how it's offered. That's why the highly trained medical professionals and board-certified cardiothoracic surgeons at St. Luke's Cardiothoracic Surgery Associates work as a team to ensure each patient receives the medical care they need. We consider patients and family members to be our partners. We encourage questions and want all to be comfortable with and understand the plan of care.


We diagnose and surgically restore, repair or replace heart and/or lung function using the latest technology.Surgical interventions include:

  • Coronary artery bypass surgery
  • Heart valve replacement
  • Coronary artery repair

Surgical Options

State-of-the-art technology gives us the option of performing surgical interventions in innovative ways that offer patients such benefits as faster recovery time, less pain and shorter hospital stays. Among the options are:

  • Beating heart surgery-In traditional heart surgery, the patient is placed on a cardiopulmonary bypass machine or heart-lung machine and the heart is stopped during surgery. In beating heart surgery, the heart is slowed enough for surgery to be possible but the patient is not placed on a bypass machine.
  • Video-assisted thorascopic surgery (VATS)-This minimally invasive surgical technique allows the surgeon to remove portions of the lung without the need for large incisions or spreading of the ribs. Using a miniature camera inserted through a one-inch incision, the surgeon is able to access the lung and "see" into the chest cavity to remove the desired tissue.
