Minimally invasive cardiac valve surgery using a partial lower sternotomy offers excellent results comparable to traditional sternotomy. This approach provides a smaller incision, improving patient outcomes and satisfaction.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Cardiac Surgery

Background:

  • Cardiac valve operations increasingly utilize smaller incisions over traditional midline sternotomy.
  • Partial sternotomy is a key area of interest for alternative surgical approaches.

Purpose of the Study:

  • To review the outcomes of cardiac valve operations performed via a partial lower sternotomy.

Main Methods:

  • A partial lower sternotomy (one-half or two-thirds) was employed in 112 patients.
  • The sternum was divided transversely and vertically, allowing access for standard instruments.
  • Cardiopulmonary bypass was established using cannulae placed through the primary incision with vacuum-assisted venous drainage.

Main Results:

  • 74 single, 35 double, and 5 triple valve operations were successfully performed.

  • Operative mortality was 5.3%, and major complication rates were comparable to full sternotomy.
  • Adequate exposure was achieved for complex procedures.

    • Conclusions:

    • Partial lower sternotomy is a viable approach for nearly all cardiac valve operations.
    • Outcomes are similar to those of full sternotomy, with the benefit of a smaller incision.
    • Patients generally prefer the smaller incision associated with this technique.
