title: Core valve implant failure in the presence of mechanical mitral prosthesis: importance of assessing left ventricular outflow tract.
abstract: Transcatheter aortic valve replacement in the presence of a mitral prosthetic valve is a technically challenging endeavor. The presence of a mitral prosthesis can alter the geometry of the landing zone for the device. A multi slice computerized tomography with comprehensive review of left ventricular outflow tract and aortic root in its entirety is critical for preventing implant failure. Technical expedients to treat implant failure involve understanding of the device as well its relationship with the mitral prosthesis.
