Background: Right ventricular (RV) dysfunction is a significant cause of morbidity and mortality after surgical correction of RVOT obstruction including tetralogy of Fallot (TOF). Transatrial repair avoids a ventriculotomy (in contrast to the transventricular approach) emphasizing maximal preservation of RV structure and function. We have adopted this technique as less traumatic for the right ventricle. This study evaluates the early surgical results of our approach.Methods: Between January 2005 to January 2014, 77 consecutive patients with RVOT obstruction were referred to our unit for surgical therapy. Of these, 14 were unsuitable for repair and underwent aortopulmonary shunting. In the remaining 63 patients (mean age of 2.67±0.38 years), complete transatrial/transpulmonary repair was performed. Previously placed shunts (four patients) were taken down. In all cases, subpulmonary resection and ventricular septal defect (VSD) closure were accomplished transatrially. In 51 patients, the main pulmonary artery was augmented with an autologous pericardial patch.Results: There were 7 (9%) deaths in this series. No patient required permanent pacemaker. Median ICU and hospital stay were 91 hours and 14 days, respectively. At median follow up of 54 (mean 51±12) months, all patients are asymptomatic, with no significant residual lesion.Conclusions: Transatrial/transpulmonary repair of TOF is associated with remarkably low morbidity and mortality in our early experience.

Background: Atrial septal defect and its closure can lead to changes in the right and left cardiac cavities' function and size. In this study, Z-scores of the cardiac chambers and the heart function were assessed, and the important complications were mentioned. Methods: This interventional cross-sectional study was done on patients who had atrial septal defect closure aged younger than 18 years. All patients were recruited for transthoracic echocardiography. About half of the patients were randomly selected. The information of angiography and its side effects belong to all patients, but the echocardiographic parameters and Z-scores belong only to the selected group. Results: A total of 370 patients underwent the atrial septal defect closure, of whom 150 patients participated in the study. The patients' average age and weight were 9.25 ± 3.44 years and 15.12 ± 11.83 kg, respectively, and the mean follow-up time was 2.56 years. Z-scores of the interventricular septal dimension in diastole, the left ventricular posterior wall dimension in diastole, the left ventricular internal dimension in systole, and Z-scores of the size of the right atrium, right ventricle, pulmonary valve annulus, and the main pulmonary artery were more than Z-scores of the normal population. Furthermore, Z-scores of the E/A and the Eat/Aat of the tricuspid valve were less than their peers. Besides, the correlation between Z-scores and the atrial septal defect size and weight of the patients was assessed, which was statistically significant, and patients who underwent atrial special defect closure at the age of fewer than three years and less than 15 kg had more normal cardiac Z-scores. Conclusions: Z-scores of the cardiac chambers and pulmonary artery were more than normal after successful closure of the atrial septal defect in the mid-term follow-up.

Purpose The purpose of this paper is to explore experiences of team culture, structure and function of an intensive support service (ISS) within the context of the recent service guidance “Building the Right Support” (NHS England, Local Government Association and Association of Directors of Adult Social Services, 2015). Reflections on the Hampshire and Southampton ISS set up in 2010 are discussed with a view to informing a debate about frameworks for ISS services nationally. Design/methodology/approach A reflective piece, drawing on experience and case examples. Findings This paper describes that a key function of an ISS is making individuals safe and this is significantly assisted by using shared team formulation, which can enable information and perspectives to be shared between and within teams as rapidly as possible. Further, a case is made for recognising the importance of inter-disciplinary practice, as the Southampton and Hampshire ISS has removed the “old fashioned” demarcations that led to individuals seeing a “procession” of different professionals from different disciplines. This relates to team structure, but importantly is about a culture of holding a shared identity based on positive behavioural support values, rather than a traditional uni-disciplinary perspective. Practical implications ISS models are being proposed by NHS England and this paper suggests some important practical aspects. Originality/value Limited literature exists examining the team culture within ISSs, which contributes to desired outcomes for service users. This paper opens a debate about structural and functional aspects of service delivery in this service model.

Hemifacial Microsomia (HFM) is a term used to identify facial deformities associated with the development ofthe first and second pairs of branchial arches, characterized by underdevelopment of one half of the face. One typeof hemifacial microsomia is oculo-auriculo-vertebral dysplasia or Goldenhar syndrome.The incidence of HFM is 1:3500-1:7000 of live births and occurs in 1 case per 1000 children with congenitaldeafness. The ratio of boys to girls is 3:2. The etiology and type of inheritance is studied insufficiently. There are threepossible pathogenetic models: vascular abnormalities and hemorrhages in the craniofacial region, damage of Meckel'scartilage, and abnormal cell development of the cranial nerve crest. Environmental factors, maternal internal factors,and genetic factors (OTX2, PLCD3, and MYT1 mutations) may also cause the development of hemifacial microsomia.The article demonstrates a clinical case of hemifacial microsomia in a newborn boy from a mother with Z-21 inthe form of deformation of the left auricle with atresia of the auditory canal and "false" ears on the right, combinedwith congenital anomaly of heart (atrial septal defect) and brain (hypoplasia of the corpus callosum).Emphasis is placed on the need of involving a multidisciplinary team of specialists in the management of thispatient both in the neonatal period and in the system of subsequent follow-up.

Abstract Purpose: The primary aim of our study was to prove that the replantation of spinous process-lamina complex is beneficial to restore the anatomical structure and function of the spine, and to find if it can reduce postoperative complications.Methods: We report two cases of cervical intraspinal tumor, whose postoperative pathological diagnosis, Respectively, are Neurilemmoma and meningioma. They all underwent the resection and replantation of spinous process-lamina complex, in which the resected spinous process-lamina complex was replanted at the end of the procedure, allowing a complete reconstruction of the posterior element of the spinal canal. Results：After the surgery, the symptoms were relieved, and no dysfunction of upper limbs and sphincter was observed. The tumors were benign pathologically and were diagnosed as Neurilemmoma and meningioma. The patient recovered and at 6-month follow-up had no complaints and in good health.Conclusion: After tumor resection, the replantation of spinous process-lamina complex is beneficial to restore the anatomical structure and function of the spine.

Abstract Pulmonary hypertension (PH) is a chronic progressive disease diagnosed when the pressure in the main pulmonary artery, assessed by right heart catheterization (RHC), is greater than 25 mmHg. Changes in the pulmonary vasculature due to the high pressure yield an increase in the right ventricle (RV) afterload. This starts a remodeling process during which the ventricle exhibits changes in shape and eventually fails. RV models were obtained from the segmentation of cardiac magnetic resonance images at baseline and 1-year follow-up for a pilot study that involved 12 PH and 7 control subjects. The models were used to create surface meshes of the geometry and to compute the principal, mean, and Gaussian curvatures. Ten global curvature indices were calculated for each of the RV endocardial wall reconstructions at the end-diastolic volume (EDV) and end-systolic volume (ESV) phases of the cardiac cycle. Statistical analysis of the data was performed to discern if there are significant differences in the curvature indices between controls and the PH group, as well as between the baseline and follow-up phases for the PH subjects. Six curvature indices, namely, the Gaussian curvature at ESV, the mean curvature at EDV and ESV, the L2-norm of the mean curvature at ESV, and the L2-norm of the major principal curvature at EDV and ESV, were found to be significantly different between controls and PH subjects (p < 0.05). We infer that these geometry measures could be used as indicators of RV endocardial wall morphology changes. Two global parameters, the Gaussian and mean curvatures at ESV, showed significant changes at the one-year follow-up for the PH subjects (p < 0.05). The aforementioned geometry measures to assess changes in RV shape could be used as part of a noninvasive computational tool to aid clinicians in PH diagnostic and progression assessment, and to evaluate the effectiveness of treatment.

AbstractObjective:Double-chambered right ventricle is characterised by division of the outlet portion of the right ventricle by hypertrophy of the septoparietal trabeculations into two parts. We aim to report our experiences regarding the presenting symptoms of double-chambered right ventricle, long-term prognosis, including the recurrence rate and incidence of arrhythmias after surgery.Methods:We retrospectively investigated 89 consecutive patients who were diagnosed to have double-chambered right ventricle and underwent a surgical intervention from 1995 to 2016. The data obtained by echocardiography, cardiac catheterisation, and surgical findings as well as post-operative follow-up, surgical approaches, post-operative morbidity, mortality, and cardiac events were evaluated.Results:Median age at the time of diagnosis was 2 months and mean age at the time of operation was 5.3 years. Concomitant cardiac anomalies were as follows: perimembranous ventricular septal defect (78 patients), atrial septal defect (9 patients), discrete subaortic membrane (32 patients), right aortic arch (3 patients), aortic valve prolapse and/or mild aortic regurgitation (14 patients), and left superior caval vein (2 patients). The mean follow-up period was 4.86 ± 4.6 years. In these patients, mean systolic pressure gradient in the right ventricle by echocardiography before, immediately, and long-term after surgical intervention was 66.3, 11.8, and 10.4 mmHg, respectively. There were no deaths during the long-term follow-up period. Surgical reinterventions were performed for residual ventricular septal defect (2), residual pulmonary stenosis (1), and severe tricuspid insufficiency (1).Conclusion:The surgical outcomes and prognosis of double-chambered right ventricle are favourable, recurrence and fatal arrhythmias are unlikely in long-term follow-up.

Abstract The atherogenic process begins already in childhood and progresses to symptomatic condition with age. We investigated the association of cholesterol efflux capacity (CEC) and vascular markers of subclinical atherosclerosis in healthy, young adults. CEC was determined in 2282 participants of the Young Finns study using cAMP treated 3H-cholesterol-labeled J774 cells. The CEC was correlated to baseline and 6-year follow-up data of cardiovascular risk factors and ultrasound measurements of arterial structure and function. CEC was higher in women, correlated with total cholesterol, HDL-C, and apolipoprotein A-I, but not with LDL-C or apolipoprotein B. Compared to the lowest CEC quartile, the highest CEC quartile was significantly associated with high CRP levels and inversely associated with adiponectin. At baseline, high CEC was associated with decreased flow-mediated dilation (FMD) and carotid artery distensibility, as well as an increased Young's modulus of elasticity, indicating adverse changes in arterial structure, and function. The association reversed with follow-up FMD data, indicating the interaction of preclinical parameters over time. A higher CEC was directly associated with a lower risk of subclinical atherosclerosis at follow-up. In young and healthy subjects, CEC was associated with important lipid risk parameters at baseline, as in older patients and CAD patients, but inversely with early risk markers for subclinical atherosclerosis.
