This study demonstrates a less invasive aortic valve replacement using a right parasternal minithoracotomy. The technique offers reduced surgical trauma and faster patient recovery, improving outcomes for aortic valve surgery.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Procedures

Background:

  • Aortic valve replacement via minithoracotomy is an emerging technique.
  • Further refinements aim to decrease procedural invasiveness.

Purpose of the Study:

  • To evaluate a refined minithoracotomy approach for aortic valve replacement.
  • To assess the safety and efficacy of this less invasive surgical strategy.

Main Methods:

  • Aortic valve replacement performed in 27 patients.
  • Utilized a right parasternal minithoracotomy without rib resection.
  • Cardiopulmonary bypass established through the same surgical access.

Main Results:

  • No intraoperative complications occurred.

  • All patients survived, with most discharged within one week.
  • Average bypass, cross-clamp, and operating times were 114, 76, and 190 minutes, respectively.
  • Early extubation was achieved in 3 patients; others extubated within 10 hours.

    • Conclusions:

    • This method further reduces surgical trauma.
    • Enables early patient mobilization and rehabilitation.
    • Key technical improvements include avoiding groin cannulation and preserving chest wall integrity.
