Endoventricular plasty (EVP) successfully restored left ventricular geometry in many patients with anteroapical aneurysms. Preserved proximal septum on echocardiography predicted successful reconstruction, guiding patient selection for this cardiac surgery.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Mechanics
  • Medical Imaging

Background:

  • Anteroapical left ventricular aneurysms impair cardiac function.
  • Endoventricular plasty (EVP) is a surgical option for these aneurysms.
  • Predictors of successful geometric reconstruction after EVP require clarification.

Purpose of the Study:

  • To evaluate the efficacy of endoventricular plasty (EVP) in reconstructing left ventricular (LV) geometry.
  • To identify predictive factors for successful LV geometry restoration after EVP.
  • To assess the operative risk associated with EVP for anteroapical LV aneurysms.

Main Methods:

  • Retrospective analysis of 65 patients undergoing EVP from 1988-1992.
  • Postoperative ventriculography and computerized silhouette analysis in 43 patients.

  • Correlation of preoperative echocardiographic findings with postoperative geometric outcomes.

    • Main Results:

    • Operative mortality was 4.6%; 9.2% required intraaortic balloon counterpulsation (IABP).
    • Successful LV geometry restoration occurred in 24/43 patients.
    • A preserved proximal septum (≥2.5 cm) on echocardiography was the sole significant predictor of successful reconstruction.

    Conclusions:

    • EVP is a viable option for anteroapical LV aneurysms, offering satisfactory geometric restoration with low operative risk.
    • Preserved proximal septum is a key indicator for successful EVP outcomes.
    • Caution is advised in patients with fibrotic proximal septa undergoing EVP.
