Minimally invasive cardiac valve surgery offers excellent safety and quality, with operative mortality comparable to conventional methods. This approach leads to shorter hospital stays, reduced costs, and a faster patient recovery.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Techniques

Background:

  • Cardiac surgery has historically lagged in adopting minimally invasive techniques compared to other surgical specialties.
  • Advances in videoscopic, thorascopic, and small incision surgery have enabled new approaches to cardiac valve surgery.
  • Minimally invasive cardiac valve surgery was initiated in 1996 for isolated valve pathology without coronary disease.

Purpose of the Study:

  • To evaluate the safety, quality, and outcomes of minimally invasive cardiac valve surgery.
  • To compare minimally invasive techniques with conventional open sternotomy procedures.
  • To summarize institutional experience with minimally invasive valve operations.

Main Methods:

  • Utilized smaller incisions and mandatory transesophageal echocardiogram (TEE) for monitoring and air removal.

  • Incorporated newer cardiopulmonary bypass and perfusion techniques.
  • Adapted standard valve repair and replacement techniques for minimally invasive access.

    • Main Results:

    • Excellent safety and quality demonstrated through the blending of TEE, perfusion techniques, and modified surgical approaches.
    • Operative mortality was comparable to conventional aortic valve replacement (AVR) and lower for minimally invasive mitral valve procedures (MVP).
    • Shorter intensive care unit (ICU) and post-ICU lengths of stay were observed, resulting in lower overall costs.

    Conclusions:

    • Minimally invasive cardiac valve surgery offers comparable or improved mortality rates versus conventional sternotomy.
    • Patients experience reduced need for blood transfusions, lower incidence of atrial fibrillation, and less post-hospital rehabilitation.
    • Faster return to normal activities and overall improved patient satisfaction are key benefits of this approach.
