Figure 3From: Delayed onset of tricuspid valve flow in repaired tetralogy of Fallot: an additional mechanism of diastolic dysfunction and interventricular dyssynchronyThree patterns of delayed onset of the tricuspid valve flow. A. Pattern A. Delayed onset of the tricuspid valve (TV) flow with prolonged ejection time (double-headed arrow) of the pulmonary arterial (PA) flow as compared to the aortic (Ao)flow. B. Pattern B. Delayed onset of the TV flow with delayed onset and cessation (arrows) of the PA flow. C. Pattern C. Delayed onset of the TV flow with synchronous PA and Ao flows. MV, mitral valve.Back to article page
