“…On M‐mode echocardiography, the lesion can present as a cloud of echoes penetrating the right ventricle during diastole. Due to improved diagnostic accuracy with saline contrast echocardiography, there is now an increase in its reported frequency 51–57 . Magnetic resonance imaging is now recognized as a modality with which to delineate the arrangement of the persisting valves of the systemic venous sinus.…”

“…Those individuals with the division of the morphologically right atrium were diagnosed between the ages of 1 day and 86 years, with a median of 23 years 23–28,31,32,34–91 . Among these individuals, seven‐tenths were female.…”

“…They depend on the degree of the partitioning of the right atrium, the patency of the atrial septum, and the extent of any obstruction to flow. In the absence of interatrial communication, and with no obstruction to flow, patients may remain asymptomatic, with the lesion discovered as a chance finding 23–28,31,32,34–88 . When the atrial septum is patent, individuals may present with varying degrees of intermittent cyanosis, syncope, paradoxical systemic, and coronary embolism ranging from severe hypoxia after birth to cyanosis in childhood 23–25,27,32,38–50 .…”

“…Division of the morphologically left atrium has been estimated to be around 0.1% to 0.4%, while the persistence of the valves of the systemic venous sinus accounts for 0.025%–0.1% of congenital heart diseases 22,29–31 . Associated congenital and acquired cardiac lesions have been reported in one‐third to three‐quarters of those with divided left atriums and in one‐half of those in whom the morphologically right atrium is divided 23–28,31–91 . Limited information is available, however, on the short‐ and long‐term outcomes of treatment for these rare conditions.…”

Background and Aim The morphological variations when one, or both, of the atrial chambers is subdivided, are many and varied. We sought to address clinical presentations, potentially misdiagnosed cases, diagnostic modalities, surgical approaches, and outcomes of this “family” of uncommon lesions. Methods A total of 193 published investigations were synthesized. Diagnostic information was provided by clinical presentation, and multimodality imaging studies. Results Almost three‐quarters of patients with divided atrial chambers present during infancy with severe pulmonary hypertension and cardiac failure. Associated cardiac and extra‐cardiac defects are present in between half and nine‐tenths of cases. Acquired division of the left atrium has been reported after the Fontan operation, orthotopic cardiac transplantation, and complicated aortic valvar infective endocarditis. Surgery under cardiopulmonary bypass remains the definitive treatment. Balloon dilation may be considered in anatomically compatible variants in the setting of cardiac failure and pregnancy as a bridge todefinitive treatment. Overall, mortality has been cited between nil to 29%. Presentation during infancy, associated congenital anomalies, pulmonary hypertension, and surgery in the previous era, have been the reported causes of death. The operative survivors have long‐term favourable outcomes, with near normal cardiac dimensions and low risk of recurrence. While asymptomatic patients with division of the right atrium do not need treatment, surgical resection of the dividing partition under cardiopulmonary bypass is recommended in symptomatic patients with complex anatomy, the spinnaker malformation, or associated cardiac anomalies. Balloon dilation may be considered in uncomplicated patients with less obstructive lesions. Hybrid intervention and endoscopic robotic correction also have been performed. Conclusions Resection of the dividing shelf allows the survivors to regain near normal dimensions with a low risk of recurrence. We submit that an increased appreciation of the anatomic background to division of the atrial chambers will contribute to improved surgical management.

The dynamic characteristics of the area of the atrial septal defect (ASD) were evaluated using the technique of real-time three-dimensional echocardiography (RT 3DE), the potential factors responsible for the dynamic characteristics of the area of ASD were observed, and the overall and local volume and functions of the patients with ASD were measured. RT 3DE was performed on the 27 normal controls and 28 patients with ASD. Based on the three-dimensional data workstations, the area of ASD was measured at P wave vertex, R wave vertex, T wave starting point, and T wave terminal point and in the T-P section. The right atrial volume in the same time phase of the cardiac cycle and the motion displacement distance of the tricuspid annulus in the corresponding period were measured. The measured value of the area of ASD was analyzed. The changes in the right atrial volume and the motion displacement distance of the tricuspid annulus in the normal control group and the ASD group were compared. The right ventricular ejection fractions in the normal control group and the ASD group were compared using the RT 3DE long-axis eight-plane (LA 8-plane) method. Real-time three-dimensional volume imaging was performed in the normal control group and ASD group (n=30). The right ventricular inflow tract, outflow tract, cardiac apex muscular trabecula dilatation, end-systolic volume, overall dilatation, end-systolic volume, and appropriate local and overall ejection fractions in both two groups were measured with the four-dimensional right ventricular quantitative analysis method (4D RVQ) and compared. The overall right ventricular volume and the ejection fraction measured by the LA 8-plane method and 4D RVQ were subjected to a related analysis. Dynamic changes occurred to the area of ASD in the cardiac cycle. The rules for dynamic changes in the area of ASD and the rules for changes in the right atrial volume in the cardiac cycle were consistent. The maximum value of the changes in the right atrial volume occurred in the end-systolic period when the peak of the curve appeared. The minimum value of the changes occurred in the end-systolic period and was located at the lowest point of the volume variation curve. The area variation curve for ASD and the motion variation curve for the tricuspid annulus in the cardiac cycle were the same. The displacement of the tricuspid annulus exhibited directionality. The measured values of the area of ASD at P wave vertex, R wave vertex, T wave starting point, T wave terminal point and in the T-P section were properly correlated with the right atrial volume (P<0.001). The area of ASD and the motion displacement distance of the tricuspid annulus were negatively correlated (P<0.05). The right atrial volumes in the ASD group in the cardiac cycle in various time phases increased significantly as compared with those in the normal control group (P=0.0001). The motion displacement distance of the tricuspid annulus decreased significantly in the ASD group as compared with that in the normal control group (P=0....
