Ebstein's anomaly

  • RV GS more positive than -18% (FWS >-20%) as independent prognostic parameter (620 patients >17a) for mortality; Strain & strain-rate improve postoperatively

Normal FWS -23,9%

Normal FWS -23,9%

  • Foreshortening of the RA leads to overestimation and a wrongly hyperdynamic strain

  • No foreshortening, significantly different values & low-normal values

Excursion: MINOCA in Ebstein's anomaly

Contrast Strain with antero- & inferolateral reduction in MINOCA (MRI proven)

Krumphuber, Altersberger, in Review 12-25

Excursion rhythmology

  • WPW: Delta-wave & timing of contraction in Strain in WPW better with TDI Strain (regional strain curves)

  • 

Brugada: GLS borderline normal vs healthy (-18,1% vs -18,8%) and Dispersion mildly prolonged (33 ms vs 38 ms). A dispersion >40 ms as an early sign for possible VT
