    Abstract The coexistence of aortic valve atresia and interrupted aortic arch are an extremely rare condition. In this pathology, blood flow to the ascending aorta and coronary arteries should be provided through the ductus arteriosus or collaterals originating from the descending aorta. In rare cases where bilateral ductus arteriosus is present, they can provide circulation. Here, we report two cases in which coronary arteries and ascending aorta were supplied by one ductus arteriosus and distal systemic circulation is supplied by a second ductus arteriosus in one patient and a collateral artery in the other. Initial palliation was successfully performed by bilateral pulmonary artery banding and transcatheter ductal stent implantation in both cases.

    Abstract Background: The right fibrous trigone, which the His bundle penetrates, is part of the subaortic area adjacent to the membranous septum. Structural alterations of the right fibrous trigone may cause conduction disturbance as a result of compression in this area after transcatheter aortic valve implantation. This study analyzed the hypothesis of whether imaging parameters of the RFT could predict the risk of conduction disturbance after transcatheter aortic valve implantation.
    Methods: We retrospectively examined 209 patients who underwent transfemoral transcatheter aortic valve implantationat a tertiary cardiac center. The different valve models were divided into 2 groups: self-expanding valve and balloon-expandable valve. Using pre-procedure computed tomography, we evaluated for the alterations of the right fibrous trigone.
    Results: New conduction disturbance was seen in 75 of 209 (35.8%) patients. Receiver operating characteristics plots displayed a right fibrous trigone density of -6 Hounsfieldunit for SEV and -16 Hounsfield unit for balloon-expandable valve as the optimal cut- off points for prediction conduction disturbance. In multiple regression analyses, the high density of RFT emerged as an independent predictor of conduction disturbance in both the self-expanding valve (odds ratio: 1.01, 95% CI: 1.01 to 1.02, P = 0.035) and bal- loon-expandable valve (odds ratio: 1.01, 95% CI: 1.01 to 1.03, P = 0.017) groups. A shorter membranous septum length and a greater implantation depth were also found to be significantly associated with a higher incidence of conduction disturbance in both trans- catheter aortic valve implantation groups.
    Conclusion: High density of right fibrous trigone is independently associated with con- duction disturbance after transcatheter aortic valve implantation, and its pre-proce- dure computed tomography evaluation can help predict the new-onset of conduction disturbance.

    Abstract Objectives: This study aimed to evaluate the clinical features of patients with septum primum malposition, imaging tools used for diagnosis, and their effects on the surgical approach.
    Materials and methods: Patients diagnosed with septum primum malposition in our paediatric cardiac centre between 1 January, 2015 and 1 January, 2019 were included in the study. In all patients, the age, reason for admission, transthoracic echocardiography, cardiac multidetector CT angiography findings, and subsequent surgical data were evaluated.
    Results: Fifteen patients were diagnosed with septum primum malposition during the study period. The median age was 12 months (2 months-10 years). Six patients were left isomeric, and the rest were situs solitus; 80% of the patients (n = 12) had additional secundum atrial septal defect. There was cardiac pathology in 46% of the patients (n = 7) in addition to the abnormal pulmonary venous drainage, ventricular septal defect (n = 3), left ventricularhypoplasia (n = 2), cortriatriatum sinister (n = 2), double outlet right ventricle (n = 1), and atrioventricular septal defect (n = 1). There was bilateral superior caval vein in three patients, right-sided superior caval vein in 11 patients, and left-sided superior caval vein in one patient. All three patients with total abnormal pulmonary venous drainage were left atrial isomeric. There were differences between the results of transthoracic echocardiography and CT angiographies in two patients. The surgical strategy was changed in three patients after the preoperative diagnosis of septum primum malposition.
    Conclusion: Septum primum malposition should be kept in mind during the imaging of complex CHDs specifically during the segmental analysis of the pathologies with heterotaxy syndromes; it should be differentiated from other aetiologies of abnormal pulmonary venous drainage as accurate diagnosis would facilitate the ideal surgery in these complex pathologies requiring a detailed preoperative preparation.

    Abstract Medical image quality assessment is an important aspect of image acquisition, as poor-quality images may lead to misdiagnosis. Manual labelling of image quality is a tedious task for population studies and can lead to misleading results. While much research has been done on automated analysis of image quality to address this issue, relatively little work has been done to explain the methodologies. In this work, we propose an explainable image quality assessment system and validate our idea on two different objectives which are foreign object detection on Chest X-Rays (Object-CXR) and Left Ventricular Outflow Tract (LVOT) detection on Cardiac Magnetic Resonance (CMR) volumes. We apply a variety of techniques to measure the faithfulness of the saliency detectors, and our explainable pipeline relies on NormGrad, an algorithm which can efficiently localise image quality issues with saliency maps of the classifier. We compare NormGrad with a range of saliency detection methods and illustrate its superior performance as a result of applying these methodologies for measuring the faithfulness of the saliency detectors. We see that NormGrad has significant gains over other saliency detectors by reaching a repeated Pointing Game score of 0.853 for Object-CXR and 0.611 for LVOT datasets.
