Submitral left ventricular aneurysms. Correction by a new transatrial approach.

M J Antunes

    The Journal of Thoracic and Cardiovascular Surgery

    Summary

    Submitral left ventricular aneurysm, a rare condition in African patients, can be effectively treated with a novel transatrial surgical approach. This method preserves mitral valve function and reduces operative risks.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Medical Research

    Background:

    • Submitral left ventricular aneurysm is a recognized but uncommon cardiac condition.
    • It predominantly affects patients of African descent and is frequently linked to mitral regurgitation.

    Purpose of the Study:

    • To evaluate a new transatrial surgical approach for treating submitral left ventricular aneurysms.
    • To assess the efficacy and safety of this technique, focusing on mitral valve preservation and patient outcomes.

    Main Methods:

    • Nine patients with submitral aneurysm underwent surgery using a transatrial approach.
    • The technique involves exposing the aneurysm neck via an incision in the left atrium floor.
    • Standard cardiopulmonary bypass was employed, with direct closure of the aneurysm neck and mitral valve repair when necessary.

    Main Results:

    • The transatrial approach successfully repaired submitral aneurysms in eight of nine patients.
    • Mitral valve function was preserved in all surviving patients.
    • One patient experienced operative mortality due to pericardial hemorrhage; the remaining patients showed good postoperative mitral valve function.

    Conclusions:

    • The transatrial approach offers a lower operative mortality and morbidity for submitral left ventricular aneurysms.
    • This technique facilitates the conservation of the mitral valve, leading to favorable long-term outcomes.
