Webb17 juni 2016 · With 3D imaging, the ventricular side of mitral prosthetic valves, which is consistently prevented with 2D imaging, can be often visualized. 27 After locating the best plane for imaging the PHV by standard 2D images, narrow-angled acquisition mode, 3D zoom mode, full-volume acquisition (single or multi-beat with ECG gating) with and … Webb3 apr. 2024 · In case of mitral valve replacement, an indexed effective orifice area <1.2 cm 2 /m 2 is considered as patient prosthesis mismatch [6]. Mitral patient prosthesis mismatch has been classified as moderate if indexed effective orifice area is >0.9 and ≤1.2 cm 2 /m 2 and as severe if ≤0.9 cm 2 /m 2 [7].

Webb17 dec. 2024 · TTE is the standard approach for periodic imaging, supplemented by TEE when prosthetic mitral valve dysfunction is a concern (see Section 11.1). Additional imaging with CT, fluoroscopy CMR, or PET is reserved for patients for whom there is concern about valve dysfunction (see Section 11.1) or endocarditis (see Section 12.1). 1,2 WebbMitral Prosthetic Valve Area calculated from pressure half time at rest is 2.06 cm2 which changed to 2.46 cm2 with exercise.
