چکیده
Microanigiographlic examinatioin of the pulmoniary arterial svstem in 12 n1ewborn in1fants with conicomitanit steniosis or atresia of the aortic anid mitral orifices showed that the intrapulmonary arterial pattern is inifluenced by the state of the forameni ovale. In inifanlts with aortic atresia with a prematuirely closed foramein ovale, that is cases in which the left side of the heart is a cul-de-sac, there is moderate or prominent tortulosity of the intralobular pulmonary arteries iindicatinig conigenital pulmonary hvpertenision. This feature is less promiinient or absent in infants with valvular insufficiency of the foramen ovale, regardless of the postnatal age of the patient.

Structural changes of the pulmonary circulation during the pathogenesis of pulmonary arterial hypertension remain to be fully elucidated. Although angiography has been used for visualizing the pulmonary circulation, conventional angiography systems have considerable limitations for visualizing small microvessels (diameters < 200 microm), particularly within a closed-chest animal model. In this ...

Structural and functional changes of pulmonary circulation related to pathophysiology of pulmonary arterial hypertension (PAH) remain to be fully elucidated. Angiographic visualization in in vivo animals provided a powerful tool for assessing the major indexes associated with the pathogenesis of PAH. In this study, we have exploited the full potential of synchrotron radiation (SR) microangiogra...
