Left thoracotomy for multiple-time redo mitral valve surgery using on-pump beating heart technique.

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Cardiac Valve Repair and Replacement

Background:

• Limited data exists on performing multiple redo mitral valve surgeries via left thoracotomy with a beating heart.
• This technique is explored due to the challenges associated with repeat sternotomies.

Purpose of the Study:

• To evaluate the safety and efficacy of left thoracotomy using an on-pump beating heart technique for patients undergoing multiple redo mitral valve surgery.

Main Methods:

• A retrospective review of 16 patients who underwent multiple redo mitral valve surgery between March 2002 and June 2007.
• Procedures were performed via left posterolateral thoracotomy with the heart beating on cardiopulmonary bypass.

Main Results:

• The study included patients with prior cardiac operations (2-3 times).
• Procedures involved mitral valve repair, replacement, or re-replacement.
• Key outcomes included operative time, cardiopulmonary bypass time, and postoperative recovery metrics (ventilation, ICU, and hospital stay).

Conclusions:

• Left thoracotomy with the on-pump beating heart technique is a safe and effective approach for multiple redo mitral valve surgery.
• This minimally invasive strategy should be considered for complex reoperative mitral valve procedures.
