Transapical Aspiration of a Mitral Mass With the AngioVac System on a Beating Heart.

The AngioVac System has already proved to be effective and safe in the treatment of thrombotic and endocarditic formations concerning the venous district and the tricuspid valve. We describe an innovative use of the AngioVac System to treat a left-sided heart mass. In a high-surgical-risk patient, we used a micro-invasive transapical access and a modified extracorporeal membrane oxygenation circuit to remove the mass from the mitral bioprosthesis without having to replace it. Further experiences are required to confirm the safety of this technique in high-risk patients.
