Surgical Ventricular Restoration  with the Dor Procedure for Anterior LV Aneurysm and Suspected Rupture: A Case Report

Background: Surgical ventricular restoration (SVR) using the Dor procedure has become increasingly rare in the era of modern revascularization and improved medical management of myocardial infarction. However, in selected patients with severe left ventricular (LV) remodeling or suspected rupture, it remains a critical surgical option. Case Presentation: A 55-year-old male presented with acute chest pain and dyspnea. Imaging revealed an extensive anterior LV aneurysm with suspected contained rupture. After successful LAD revascularization, the patient underwent SVR using the Dor procedure. Intraoperative findings confirmed a large thrombus and dyskinetic segments, which were excluded using a Dacron patch. Postoperative recovery was uneventful. Outcome: At four-year follow-up, the patient remains asymptomatic with preserved LV function and no signs of recurrence. Conclusion: This case illustrates that the Dor procedure remains a valuable life-saving strategy in select patients with post-infarction LV aneurysms and suspected rupture, particularly when rapid diagnosis and timely surgical intervention are achieved.
