This study used XPCT in order to evaluate the ascending aorta specimens from patients with acute type A aortic dissection (AADA) to analyze the morphological changes in the condition. Methods: Twelve aortic specimens were obtained during repairs for AADA and fixed with formalin. Five specimens had Marfan syndrome (MFS), and seven did not have MFS. Six normal aortas were obtained from the autopsy. Using XPCT (effective pixel size, 12.5 μm), the density of the tunica media (TM) was measured at eight points for each sample. The specimens were subsequently analyzed pathologically. Results: The density of the TM was almost constant within each normal aorta (mean ± standard deviation, 1.081 ± 0.001 g/cm3). The mean density was significantly lower for the formalin-fixed AADA aortas (1.066 ± 0.003 g/cm3; p Conclusion: XPCT demonstrated differences in the structure of the aortic wall in aortic dissection specimens with and without MFS and normal aortas. Medial density was homogeneous in the normal aortas, markedly varied in those with MFS, and was significantly lower and different among those without MFS. These changes would be presented in the TM before the onset of aortic dissection.. |

The present study aimed to clarify the pathogenesis of PIT in humans. Methods: Coronary arteries were obtained from 43 autopsy subjects aged 15–49 years. Non-atherosclerotic intima and atherosclerotic intimal lesions were classified into four groups, i.e. diffuse intimal thickening, fatty infiltration, fatty streak, and PIT, and the number and density of macrophages and smooth muscle cells (SMCs) were determined. Components of the lesions and proliferative and apoptotic activities of macrophages and SMCs were investigated by immunohistochemistry and TUNEL assay. Results: Extracellular lipids accumulated mildly in the fatty infiltration and fatty streak, and abundantly in the PIT to form the lipid pool. The extracellular lipids co-localized with apolipoprotein B and fibrinogen. Macrophage foam cells accumulated in the fatty streak and PIT, but no TUNEL-positive macrophages were detected in any lesion. No significant difference in the number of SMCs was found between the four groups, but the density of SMCs decreased in the fatty streak and PIT. The decrease correlated with an increase in the number of macrophages, and the accumulation of extracellular lipids in the lipid pool. Neither Ki-67-positive nor TUNEL-positive SMCs were detected in any lesion. Conclusions: In PIT in human atherosclerosis, the lipid pool is formed by infiltration and deposition of plasma-derived lipids. Intimal SMCs are dispersed in association with macrophage infiltration and lipid pool formation without undergoing significant proliferation or death.. |

To resolve the three-dimensional (3D) morphology, we have applied PCXI to various cardiovascular tissue samples, including the thoracic aorta, ductus arteriosus, and cardiac conduction system. In the aortic walls, PCXI demonstrated differences in 3D structures of tunica media of aortic dissection. These findings correlated well with the irregularity of the structure of the media. In the surgically excised sample of coarctation of the aorta, PCXI showed 3D morphological changes in transition from the ductus arteriosus to the descending aorta. PCXI is also useful for examining abnormalities of the cardiac conduction system in congenital heart defects. Synchrotron radiation-based X-ray phase-contrast tomography has strong modality for analyzing 3D morphology and is useful for understanding the pathophysiology of various cardiovascular surgical pathologies.. |
