This communication reports 4 cases of pulmonary-valve atresia with intact ventricular septum and hypoplastic right ventricle in which angiography demonstrated large diverticula and sinusoids that ...

At the same time, relaxation of the trabecular smooth muscle increases the compliance of the sinusoids, facilitating rapid filling and expansion of the sinusoidal system (Figure 1). The subtunical ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed.
