Summary

Minimally invasive valve surgery (MIVS) using less invasive valve surgery (LIVS) and port-access valve surgery (PAVS) show comparable early outcomes. LIVS is more cost-effective, but PAVS offers a faster return to work.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Techniques
  • Surgical Outcomes

Background:

  • Minimally invasive approaches are increasingly applied to valvular operations.
  • This study reviews experiences with less invasive valve surgery (LIVS) and port-access valve surgery (PAVS).

Purpose of the Study:

  • To compare the safety and cost-effectiveness of LIVS and PAVS.
  • To evaluate post-discharge follow-up outcomes for both minimally invasive valve surgery techniques.

Main Methods:

  • A retrospective review of 40 port-access valve surgery (PAVS) and 66 less invasive valve surgery (LIVS) procedures.
  • Comparison of preoperative variables, intraoperative data, operative mortality, and postoperative outcomes.

Main Results:

Related Experiment Videos

  • Port-access valve surgery (PAVS) patients were younger with better left ventricular function.
  • Operating room time, surgery time, and cross-clamp time were longer in the PAVS group.
  • Operative mortality was 3% for LIVS and 5% for PAVS; LIVS had more new atrial fibrillation.
  • Return to work was similar, but PAVS patients returned approximately 4 weeks sooner.

Conclusions:

  • Early clinical outcomes for LIVS and PAVS are comparable, emphasizing patient selection.
  • Less invasive valve surgery (LIVS) appears more cost-effective currently.
  • Port-access valve surgery (PAVS) demonstrates an advantage in early return to work, suggesting its potential role in minimally invasive valve surgery.
