2020, International Journal of CardiologyCitation Excerpt :These patients were compared to an historical cohort of 139 SAPIEN XT recipients (from the same 2 centers) who had pre- and post-TAVR assessments similar to those of the SAPIEN 3 group. TTE and CMR examinations in the SAPIEN XT group were performed at a median of 6 [3–25] and 12 [7–20] days post-TAVR, respectively. Baseline, procedural, CMR and TTE data from all patients were prospectively collected in a dedicated database.

2019, JACC: Cardiovascular ImagingAssistive technology using regurgitation fraction and fractional-order integration to assess pulmonary valve insufficiency for pre-surgery decision making and post-surgery outcome evaluation
2018, Biomedical Signal Processing and ControlCitation Excerpt :Visual manner was used to acquire a spectral pulsed Doppler recording of the PAF velocity waveforms and to indicate the systolic and diastolic flow velocity signals. The CMR method was also able to directly obtain the regurgitation flow with a high accuracy and reproducibility using the phase-contrast velocity mapping technique [5,30–32]. It was a reliable tool for the assessment of the severity of the regurgitation using flow-versus-time plot, reflecting forward flow from the ventricular stroke and regurgitation flow per each cardiac cycle.
