Prophylactic LVAD Enabling High-Risk Mitral Repair-Extending Beyond the Guidelines

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Heart Failure Management

Background:

• Severe degenerative mitral regurgitation (DMR) with severe left ventricular (LV) dysfunction is typically a contraindication for mitral repair due to concerns about LV reserve and workload.
• Patients with severe DMR and LV dysfunction often present with advanced heart failure symptoms, including cardiogenic shock.

Observation:

• A 55-year-old male presented in cardiogenic shock with undiagnosed severe DMR and severe LV dysfunction.
• Standard treatment guidelines would contraindicate mitral valve repair in this high-risk scenario.

Findings:

• A high-risk mitral repair was successfully performed.
• A prophylactic CentriMag LV assist device was inserted concurrently.
• The patient showed significant improvement in LV function and clinical symptoms post-procedure, with a competent mitral valve.

Implications:

• This case suggests that combined mitral repair and LV assist device insertion can be a viable and successful strategy for select patients with severe DMR and severe LV dysfunction presenting in cardiogenic shock.
• This innovative approach may expand treatment options for patients previously considered inoperable.
• Further research is warranted to evaluate the long-term outcomes and broader applicability of this combined therapeutic strategy.
