| 1 | New Insights into Sinus Venosus Defects from Cross-Sectional Imaging显示文摘Sinus venosus defects include two varieties,superior and inferior sinus venosus defects.The superior sinus venosus defect is characterized by abnormal communication between two closely related venoatrial structures:1)the normally positioned superior vena cava-right atrium complex and 2)the right pulmonary vein-left atrium complex that is displaced leftward,forward and upward.Inferior sinus venosus defects primarily involve the inferior vena cava-right atrial junction while the right pulmonary vein-left atrial junction can also be affected.Because of the rarity and wide variation of the defects,the morphological characterization of sinus venosus defects is inconsistent among investigators and often inaccurate.Modern imaging technologies with high spatial and temporal resolutions have allowed accurate and detailed assessment of the pathological anatomy in larger numbers of cases.In this pictorial essay,we revisit the established and controversial features of the sinus venous defects using twodimensional(2D)and three-dimensional(3D)images obtained by magnetic resonance(MR)or computed tomography(CT)with brief discussion on imaging and treatment strategies. | Shi-Joon Yoo Sanga Lee Regina de la Mora Ankavipar Saprungruang Christoph Haller Lee N.Benson Vladimiro Vida Alvise Guariento Christopher Z.Lam | 2022 | Congenital Heart Disease2022，17，1： | 0 |
| 2 | Disharmonious Ventricular Relationship and Topology for the Given Atrioventricular Connections.Contemporary Diagnostic Approach Using 3D Modeling and Printing显示文摘In the last issue,two case reports separately present examples of the extremely rare and complex congenital heart diseases that show concordant atrioventricular connections to the L-looped ventricles in the presence of situs solitus.Both cases highlight that the relationship between the two ventricles within the ventricular mass is not always harmonious with the given atrioventricular connection.Such disharmony between the connections and relationships requires careful assessment of the three basic facets of cardiac building blocks,namely their morphology,the relationship of their component parts,and their connections with the adjacent segments.3D imaging and printing can now facilitate an otherwise difficult diagnosis in such complex situations.Rotation of either the 3D images or the models permit accurate assessment of the ventricular topologic pattern by creating the right ventricular en-face septal view,thus facilitating placement of the observer’s hands.As we now emphasize,an alternative approach,which might prove more attractive to imagers,is to rotate the ventricular mass to provide the ventricular apical view,thus permitting determination of the ventricular relationship without using the hands. | Shi-Joon Yoo Ankavipar Saprungruang Christopher Z.Lam Robert H.Anderson | 2022 | Congenital Heart Disease2022，17，5： | 0 |
