Minimally invasive aortic root replacement using partial upper J-sternotomy is feasible, showing lower mortality than predicted. This approach offers a viable option for select patients undergoing complex aortic procedures.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Cardiac Surgery
  • Aortic Root Surgery

Background:

  • Minimally invasive aortic valve surgery demonstrates comparable or superior outcomes to standard sternotomy.
  • Previous studies reported reduced blood loss, cross-clamp time, and hospital stay with minimally invasive approaches.
  • The study expands the evaluation of minimally invasive techniques to aortic root surgery.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of minimally invasive aortic root replacement over an 8-year period.
  • To compare observed mortality with predicted mortality for this procedure.
  • To assess the safety and efficacy of partial upper J-sternotomy for aortic root surgery.

Main Methods:

  • A cohort of 35 patients underwent aortic root replacement via partial upper J-sternotomy between December 1997 and November 2005.

  • Graft types included homografts (74.3%) and valved conduits (bioprosthesis or mechanical).
  • Preoperative EuroSCORE and predicted mortality were recorded; follow-up averaged 51 months.

    • Main Results:

    • Mean aortic cross-clamp time was 126 minutes, and cardiopulmonary bypass time was 182 minutes.
    • Low rates of bleeding revision (2.9%) and no postoperative strokes were observed.
    • Early mortality was 8.5% (3 patients), with 74.4% actuarial survival at 99 months.

    Conclusions:

    • Minimally invasive aortic root replacement is a challenging yet feasible procedure.
    • Observed mortality was lower than predicted, suggesting the technique's effectiveness.
    • The procedure is recommended for good-risk patients undergoing aortic root surgery.
