Pushing Surgical Boundaries: 3D Video-Assisted Endoscopic Dor Procedure and Mitral Valve Repair for Post-Infarction LV Aneurysm
Aluthman U, Alama A. Pushing Surgical Boundaries: 3D Video-Assisted Endoscopic Dor Procedure and Mitral Valve Repair for Post-Infarction LV Aneurysm. October 2025. doi:10.25373/ctsnet.30466982
A 55-year-old male with no known medical diseases presented to the emergency department with exertional dyspnea that had became severe in the past three days.
Echocardiography was performed as part of his workup and showed a reduced ejection fraction of 30 percent with a dilated left ventricle (LV), along with an inferior wall aneurysm of the left ventricle and severe mitral regurgitation.
Catheterization was performed and revealed a single vessel coronary artery disease in the form of a chronic total occlusion of the left circumflex artery (LCX). The patient was started on medical therapy. To complete his workup, the patient underwent magnetic resonance imaging (MRI), which reported basal lateral and inferolateral myocardial infarction along with a large, contained aneurysm measuring approximately 8.1 x 5.3 x 7.1 cm with a wide neck of 5.1 cm.
The case was discussed in the heart team meeting and the patient was referred for surgical repair. The patient subsequently underwent a total endoscopic Dor procedure to repair the LV.
