Endoventricular circular patch plasty (EVCPP) effectively treats ischemic cardiomyopathy by improving left ventricular function and patient outcomes. This surgical procedure excludes akinetic segments, enhancing heart function and quality of life for patients with chronic heart failure.

Area of Science:

  • Cardiovascular Surgery
  • Cardiology
  • Regenerative Medicine

Background:

  • Ischemic cardiomyopathy results from myocardial infarction, leading to chronic heart failure.
  • Characterized by a non-aneurysmal, diffuse akinetic left ventricle.
  • Significant impact on patient morbidity and mortality.

Purpose of the Study:

  • To evaluate the mid-term efficacy of endoventricular circular patch plasty (EVCPP).
  • To assess improvements in left ventricular function and clinical status.
  • To determine the impact on patients with ischemic cardiomyopathy.

Main Methods:

  • A cohort of 54 patients with ischemic cardiomyopathy underwent EVCPP.
  • Concomitant procedures included coronary artery bypass grafting (94%) and mitral valve reconstruction (35%).

  • Pre- and post-operative left ventricular function, volumes, and clinical status were analyzed.

    • Main Results:

    • Hospital mortality was 12.9%, with higher rates in emergency cases.
    • Late deaths occurred in 11.1% of patients.
    • Survivors showed significant improvement: ejection fraction increased from 22.8% to 36.2%, LV volumes reduced, and 88% improved to NYHA class I or II.
    • 1-, 2-, and 3-year actuarial survival rates were 87.9%, 82.7%, and 77.2%.

    Conclusions:

    • EVCPP is effective in excluding akinetic left ventricular segments.
    • The procedure significantly improves left ventricular function.
    • EVCPP leads to enhanced clinical status in patients suffering from ischemic cardiomyopathy.
