Abstract OBJECTIVES Atrioventricular valve regurgitation is known to adversely impact outcomes of single-ventricle palliation, and valve repair rarely provides long-lasting results. Closure of a atrioventricular valve can sometimes be performed, but the long-term outcomes of this manoeuvre are unknown. METHODS This retrospective study was conducted using patient data extracted from an existing bi-national, population-based registry of survivors of the Fontan procedure. RESULTS Between January 1975 and June 2018, 1574 patients survived to hospital discharge with an intact Fontan circulation. Of these patients, 128 with a common atrioventricular valve were excluded. Thirty-eight patients underwent closure of an atrioventricular valve, and complete follow-up data were available for 36 patients. Twenty-nine patients underwent closure of the tricuspid valve and 7 patients underwent closure of the mitral valve. Seventeen patients underwent valve closure prior to Fontan, 13 patients underwent valve closure concomitant with Fontan and 6 patients underwent valve closure post-Fontan. Valve closure was performed using a patch technique in 29 cases and with direct suture in 7 cases. At the most recent echocardiography, 33 patients had no regurgitation, 2 patients had recurrent mild regurgitation and 1 patient had no echocardiographic follow-up. Six patients required reintervention post-valve closure and 7 patients required permanent pacemaker insertion post-valve closure. Freedom from reintervention at 1, 5 and 18 years post-valve closure was 86% [95% confidence interval (CI) 76–98%], 83% (95% CI 72–96%) and 83% (95% CI 72–96%), respectively. CONCLUSION Atrioventricular valve closure is an effective surgical technique in selected patients with a single ventricle providing long-lasting competency in the majority of cases.

ObjectiveMore patients with Fontan physiology are reaching adulthood. The purpose of this meta-analysis was to evaluate the late outcomes of patients palliated with Fontan procedure and to assess the risk factors for mortality.MethodsPubMed, Embase and Web of Science were queried to retrieve observational studies of survival in patients following the Fontan procedure with ≥5 years of follow-up. A random-effects model was used to determine pooled survival estimates at 5, 10 and 15 years. Meta-regression was used to assess potential moderators for death.ResultsNineteen articles with a total of 5859 patients were included. The weighted mean follow-up time was 8.94±2.64 years with overall 8.3% deaths and 1.5% transplants. Pooled survival estimates at 5, 10 and 15 years were 90.7%, 87.2% and 87.5%, respectively; and 88.4%, 85.7% and 84.1%, respectively, for studies that included all three time intervals (n=4). Earliest surgical year included in the study, proportion of atriopulmonary connections versus extracardiac conduit or lateral tunnel, and older age at Fontan were associated with higher rates of death, but ventricular morphology was not. Protein-losing enteropathy, reoperation and pacemaker insertion were reported in 2.1%, 5.6% and 6.8% patients, respectively.ConclusionsSurvival following the Fontan procedure has improved with time and is influenced by Fontan type and age at the time of Fontan. At a mean follow-up of 8.9 years, there was no significant association between survival and ventricular morphology, not taking into account the mortality prior to Fontan.

Introduction: Development of atrioventricular valve regurgitation (AVVR) with or without ventricular dysfunction (VD) often occurs during the first 6 months of life and has a significant impact on outcomes for single-ventricle patients. Yet, it is not well known whether AVVR causes VD or vice versa. Thus, we sought to identify the timing and causal relationship between AVVR and VD. Methods: Among 156 consecutive single-ventricle patients who had staged palliation (2005- 2012), 28 who had AVV repair at the time of stage II (n=24, 86%) or inter-stage (n=4, 14%) were reviewed. Diagnosis included HLHS in 17 (61%) patients, tricuspid atresia in 2 (7%), and others in 9 (32%). Ventricular morphology was left-dominant in 6 (21%) patients and right-dominant in 22 (79%). AVV morphology included mitral in 6 (21%) patients, tricuspid in 18 (64%), and common in 4 (14%). Serial echocardiograms were reviewed to identify the timing of development of AVVR and/or VD. Results: After stage I palliation, ventricular end-diastolic dimension (VEDD) z-score significantly increased from 4.01 to 5.69 (p<0.01) AVVR (Figure). By the time of stage II palliation, VEDD further increased and subsequent AVV annular dilation occurred, resulting in 23 patients with significant AVVR. None of the patients, however, had significant VD before stage II palliation/AVV repair, but 9 patients developed significant VD after AVV repair. Conclusions: Ventricular dilation occurred immediately after stage I palliation and continued until stage II palliation. Secondary annular dilation occurred inter-stage and this further triggered the development of AVVR. Tangible ventricular dysfunction was not seen before AVV repair, however, important ventricular dysfunction was unmasked after volume unloading surgery. Heart failure management and early intervention to significant AVVR may reduce the incidence of ventricular dysfunction following AVV repair.

Objective:To investigate the effect of tumour necrosis factor (TNF) antagonist treatment on workforce participation in patients with rheumatoid arthritis (RA).Methods:Data from the Stockholm anti-TNFα follow-up registry (STURE) were used in this observational study. Patients with RA (n = 594) aged 18–55 years, (mean (SD) 40 (9) years) followed for up to 5 years were included with hours worked/week as the main outcome measure. Analyses were performed unadjusted and adjusted for baseline age, disease duration, Health Assessment Questionnaire (HAQ), 28-joint Disease Activity Score (DAS28) and pain score.Results:At baseline patients worked a mean 20 h/week (SD 18). In unadjusted analyses, significant improvements in hours worked/week could already be observed in patients at 6 months (mean, 95% CI) +2.4 h (1.3 to 3.5), with further increases compared to baseline at 1-year (+4.0 h, 2.4 to 5.6) and 2-year follow-up (+6.3 h, 4.2 to 8.4). The trajectory appeared to stabilise at the 3-year (+6.3 h, 3.6 to 8.9), 4-year (+5.3 h, 2.3 to 8.4) and 5-year follow-up (+6.6 h, 3.3 to 10.0). In a mixed piecewise linear regression model, adjusted for age, sex, baseline disease activity, function and pain, an improvement of +4.2 h/week was estimated for the first year followed by an added improvement of +0.5 h/week annually during the years thereafter. Over 5 years of treatment, the expected indirect cost gain corresponded to 40% of the annual anti-TNF drug cost in patients continuing treatment.Conclusion:Data from this population-based registry indicate that biological therapy is associated with increases in workforce participation in a group typically expected to experience progressively deteriorating ability to work. This could result in significant indirect cost benefits to society.

AbstractObjectiveThe objective of this study was to evaluate the early and late results of atrioventricular valve surgery after Fontan operation.BackgroundAtrioventricular valve regurgitation is a known perioperative risk factor for Fontan operation. There are limited data on the outcomes of late atrioventricular valve surgery following Fontan operation.MethodsPatients who underwent atrioventricular valve surgery following Fontan procedure were identified from the Mayo Clinic Fontan database. Medical records were reviewed for pre-operative, operative, and post-operative clinical and haemodynamic data. All patients not known to be deceased were sent health status questionnaires.ResultsA total of 61 patients (28 females) underwent atrioventricular valve surgery following Fontan procedure. The median age at atrioventricular valve surgery was 14 years. The median duration between Fontan and atrioventricular valve surgery was 4.7 years. Median follow-up was 9 years. There were a total of 32 (52%) deaths with 8 (13%) within 30 days of surgery. The 5-, 10-, and 15-year survival rates were 67%, 57%, and 45%, respectively. On follow-up, 44 of 61 (72%) had arrhythmias, 21 of 29 (72%) were symptomatic, and 12 of 61 (20%) developed protein-losing enteropathy. On multivariate analysis, reduced ventricular function and development of protein-losing enteropathy were associated with decreased survival.ConclusionAtrioventricular valve surgery after Fontan procedure is associated with substantial late morbidity and mortality. Atrioventricular valve surgery in this cohort of patients portends poor long-term outcome and is associated with a high incidence of protein-losing enteropathy. Reduced ventricular function and development of protein-losing enteropathy were associated with decreased survival.

AbstractIntroductionSignificant atrioventricular valve regurgitation at diagnosis in single-ventricle patients has been associated with mortality and morbidity. However, longitudinal data on the effect of valve regurgitation at diagnosis on outcomes in the era of surgical valve interventions are scarce.Materials and methodsThis is a retrospective review of single-ventricle patients admitted to a regional centre from 2005 to 2008. Data were reviewed from birth to 18 months, and association of atrioventricular valve regurgitation at diagnosis with mortality and morbidity was evaluated.ResultsA total of 118 patients were studied, 73% with a single right ventricle. At diagnosis, 37 patients (31%) had mild, 5 (4%) had mild to moderate, and 4 (3%) had ≥ moderate atrioventricular valve regurgitation. Moderate or greater valve regurgitation was associated with mortality (HR 5.51, 95% CI 1.24–24.61, p = 0.025), and all four patients with ≥ moderate valve regurgitation died. However, valve regurgitation was not associated with mortality for left ventricle patients. In all, 12 patients (10%) had surgical atrioventricular valve interventions. There were no independent predictors of valve intervention, and no patient having an intervention had > mild valve regurgitation at diagnosis. There was no association between valve regurgitation and days of hospitalisation or chest tube drainage.ConclusionSignificant atrioventricular valve regurgitation at diagnosis remains a risk factor for mortality in single-ventricle patients, although it may be less important for single left ventricle patients. However, it is not associated with increased morbidity or surgical atrioventricular valve intervention in survivors. Reliably predicting surgical atrioventricular valve intervention remains a challenge in single-ventricle patients.
