Combined TMR and mitral valve replacement via left thoracotomy

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Cardiac Procedures
• Interventional Cardiology

Background:

• Coronary artery disease (CAD) often leads to ischemic mitral regurgitation (IMR) in patients unsuitable for standard revascularization.
• Transmyocardial laser revascularization (TMLR) is an established therapy for refractory angina.
• IMR significantly impacts patient prognosis and quality of life.

Observation:

• This report details the novel application of TMLR in conjunction with mitral valve replacement.
• The combined procedure was performed via a left lateral thoracotomy, a minimally invasive approach.
• This approach was utilized for patients with IMR secondary to advanced CAD.

Findings:

• The combined TMLR and mitral valve replacement successfully addressed IMR in the reported cases.
• The left lateral thoracotomy approach facilitated simultaneous treatment of both conditions.
• This strategy offers a potential solution for complex cardiac pathologies.

Implications:

• This combined surgical technique may expand treatment options for patients with complex CAD and IMR.
• Minimally invasive approaches like left lateral thoracotomy are crucial for improving surgical outcomes.
• Further research is warranted to evaluate the long-term efficacy and safety of this combined TMLR strategy.
