Summary
Cardiomyoplasty (CMP) improved heart function and reduced hospitalizations in cardiac failure patients. This circulatory assistance technique showed a 4-year survival rate of 68.3% in survivors.
Area of Science:
- Cardiovascular Surgery
- Cardiac Assist Devices
- Muscle Flap Transplantation
Context:
- Cardiomyoplasty (CMP) is a surgical technique for circulatory assistance.
- It involves wrapping a latissimus dorsi muscle around the heart and stimulating it during systole.
- This study evaluated CMP in 64 patients with cardiac failure between 1985 and 1993.
Purpose:
- To assess the efficacy and outcomes of cardiomyoplasty in patients with severe cardiac failure.
- To identify preoperative predictors of late mortality following CMP.
Summary:
- Sixty-four patients with various causes of cardiac failure underwent CMP.
- Hospital mortality was 20.3%. Survivors showed significant improvements in functional class, ejection fraction, and cardiac index at 12 months.
- Admissions for congestive heart failure decreased significantly post-surgery.
Impact:
- CMP demonstrated significant functional and hemodynamic improvements in cardiac failure patients.
- Predictive factors for mortality included advanced NYHA class, severe cardiac dilatation, low ejection fraction, and pulmonary hypertension.
- The actuarial 4-year survival rate was 68.3%.
