Doppler echocardiography of 119 normal-functioning St Jude Medical Mitral Valve prostheses: a comprehensive assessment including time-velocity integral ratio and Prosthesis performance index.
Journal of the American Society of Echocardiography, 2005Co-Authors: Joseph F. Malouf, Manfredi Ballo, Heidi M. Connolly, David O. Hodge, Regina M. Herges, Charles J. Mullany, Fletcher A. MillerAbstract:The purpose of this study was to provide, in a large number of patients, comprehensive Doppler echocardiographic assessment of normal St Jude Medical Mitral Valve Prosthesis function using Doppler-derived hemodynamic variables, including the Mitral Valve Prosthesis-to-left ventricular outflow tract time-velocity integral ratio and Prosthesis performance index. The pressure half-time was less than 130 milliseconds in all patients, and all but one patient had either a peak early Mitral diastolic velocity of 2 m/s or less or a Mitral Valve Prosthesis-to-left ventricular outflow tract time-velocity integral ratio of less than 2.2. There was a significant ( P

Doppler Echocardiography of Normal Starr-Edwards Mitral Prostheses: A Comprehensive Function Assessment Including Continuity Equation and Time-velocity Integral Ratio
Journal of the American Society of Echocardiography, 2005Co-Authors: Joseph F. Malouf, Manfredi Ballo, David O. Hodge, Regina M. Herges, Thomas A. Orszulak, Fletcher A. MillerAbstract:The purpose of this study was to provide comprehensive Doppler echocardiographic assessment of the function of the normal Starr-Edwards Mitral Valve Prosthesis using all the Doppler hemodynamic variables described to date, including the Mitral Valve Prosthesis time-velocity integral (TVI)/left ventricular outflow tract TVI ratio and the Prosthesis performance index. All patients had a peak early Mitral diastolic velocity of no more than 2 m/s or a pressure half-time that was less than 130 milliseconds. All but one patient had either a peak early Mitral diastolic velocity of no more than 2 m/s or a Mitral Valve Prosthesis TVI/left ventricular outflow tract TVI ratio of less than 2.2, regardless of Prosthesis size or left ventricular systolic function. There was a trend of decreasing Prosthesis performance index with increasing Prosthesis Valve size that was not statistically significant, however.

transcatheter aortic Valve implantation for treatment of failing homograft with preexisting mechanical Mitral Prosthesis
Catheterization and Cardiovascular Interventions, 2013Co-Authors: Rizwan Attia, Vinnie BapatAbstract:Transcatheter aortic Valve implantation is increasingly used to treat bioprosthetic degeneration. Valve-in-Valve technique has been performed successfully to treat homograft, stentless, and stented bioprosthetic dysfunction. The presence of a Prosthesis in the Mitral position can make the transcatheter aortic Valve implantation procedure challenging due to proximity of the Mitral and aortic annuli. We describe the case of a 66-year-old who underwent the first successful implantation of Edwards Sapien device in a failing homograft in the presence of a mechanical Mitral Valve Prosthesis.

subvalvular pannus and thrombosis in a Mitral Valve Prosthesis
Journal of Cardiovascular Computed Tomography, 2016Co-Authors: Gun Ha Kim, Dong Hyun Yang, Joonwon Kang, Daehee Kim, Sungho Jung, Taehwan LimAbstract:Abstracts A 69-year-old female underwent cardiac CT to evaluate prosthetic Valve (PHV) dysfunction detected on echocardiography. A CT coronal and en face views of the Mitral annular plane showed a low-density, mass-like lesion on the left atrial side of the PHV and a high-density, plate-like lesion on the left ventricular side of PHV. A repeat of the Mitral Valve replacement was performed, and preoperative CT findings of both the thrombus on the left atrial side and pannus formation on the LV side were confirmed in the operative findings.
