Conclusion
Our series of 12 patients shows the feasibility of successfully
performing transcatheter bioprosthetic MV in surgically implanted
degenerated MV prostheses or severe native MV stenosis following a
surgically implanted mitral annuloplasty ring in patients with thrombus
present in the LAA and/or LA body. Utilization of both 2D and 3DTEE
especially 3DTEE was essential in avoiding contact with the thrombus and
preventing any embolic complications. Our number of cases is small, and
a much larger study is needed to assess the safety and efficacy of this
procedure in such patients.
