The Estech procedure offers a safer alternative for redo mitral surgery in patients with open bypass grafts, avoiding aortic clamping and graft damage. This approach demonstrated good outcomes in a complex patient cohort.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Cardiac Surgery
  • Mitral Valve Surgery

Background:

  • Redo-coronary artery bypass grafting (CABG) is high-risk with open grafts.
  • Mitral valve surgery in patients with prior CABG requires careful graft preservation.
  • The Estech procedure was explored to mitigate risks associated with traditional redo mitral surgery.

Purpose of the Study:

  • To evaluate the safety and efficacy of the Estech procedure for redo mitral surgery.
  • To assess an alternative approach to minimize damage to open bypass grafts.
  • To determine the feasibility of using remote access perfusion (RAP) endoclamp catheter in complex redo mitral valve cases.

Main Methods:

  • The Estech procedure was performed on 10 patients with previous cardiac operations between 1998 and 2000.

  • Anterior left thoracotomy and peripheral femoral cannulation with the Estech endovascular balloon technique were utilized.
  • Procedures included mitral valve replacement, reconstruction, and paravalvular leak closure.

    • Main Results:

    • One patient required conversion to standard re-sternotomy due to aortic atherosclerosis; no bypass graft damage occurred.
    • One non-procedure-related hospital death due to intestinal infarction and multiple organ failure (MOF) was observed.
    • All survivors achieved acceptable New York Heart Association (NYHA) functional class post-procedure.

    Conclusions:

    • The Estech procedure provides excellent results in complex redo mitral surgery patients.
    • This technique offers a viable alternative to avoid damage to open bypass grafts.
    • The Estech procedure is recommended as a standard approach for redo mitral surgery in selected patients.
