FIGURE LEGENDS:
Figure (1): Assessment of right ventricular (RV) function by automated
Simpson’s monoplane method in a post-Senning 13 years old child post
Senning repair. A showed RV EF of 39 % at rest and B showed improved RV
EF to 43% at peak DSE. The improvement in RV EF was less than 5%.
RV: Right ventricular, EF: ejection fraction, DSE: Dobutamine Stress
echocardiography, EDV: End-diastolic volume, ESD: End-systolic volume,
RA: Right atrium, SRV: Systemic right ventricle, PVB: Pulmonary venous
baffle.
Figure (2): Quantitative Assessment of contractile reserve by assessing
right ventricular (RV) function using speckle tracking based GLS in an
11 years old child post Senning repair. A showed RV GLS of -11.2 % at
rest and B showed improvement of RV GLS to -15.6 % at peak DSE. The
improvement in RV Speckled based GLS in this patient was
>2% (-4.4%).
RV: Right ventricular, GLS: Global longitudinal strain, DSE: Dobutamine
Stress echocardiography, GS: Global strain, RA: Right atrium, SRV:
Systemic right ventricle, LV: Left ventricle, PVB: Pulmonary venous
baffle.
