Surgical techniques for left ventricular aneurysm treatment were reviewed. Aneurysmectomy with converging walls reconstruction offers improved survival and ventricular function compared to other methods.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Techniques
  • Left Ventricular Aneurysm Treatment

Context:

  • Left ventricular aneurysms often result from myocardial infarction, leading to impaired cardiac function.
  • Surgical intervention is necessary for symptomatic or high-risk patients.
  • Traditional techniques have limitations in restoring normal ventricular morphology and function.

Purpose:

  • To critically review and compare surgical techniques for left ventricular aneurysm treatment.
  • To evaluate the efficacy and outcomes of aneurysm plication and different aneurysmectomy methods.
  • To highlight the advantages of aneurysmectomy with converging walls reconstruction.

Summary:

  • Aneurysm plication, used in 35 patients with coronary artery bypass grafting, is rarely employed due to papillary muscle damage risk.

  • Conventional aneurysmectomy in 175 patients resulted in 8% operative mortality and suboptimal ventricular reshaping.
  • Aneurysmectomy with converging walls reconstruction (Jatene technique modification) in 51 patients showed lower operative mortality (3.9%) and improved 3-year survival (89.9%).

    • Impact:

    • The converging walls technique significantly improves left ventricular ejection fraction (from 28.2% to 42%) and reduces end-diastolic pressure (from 23.6 to 18 mmHg).
    • This approach allows complete aneurysm removal and better restoration of normal left ventricular morphology.
    • Improved clinical outcomes and ventricular function suggest this technique is superior for left ventricular aneurysm treatment.
