Abstract Background Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease, and sudden cardiac death represents an important mode of death in these patients. Data evaluating the implantable cardioverter defibrillator (ICD) in this patient population remain scarce. Purpose We aimed to describe long-term follow-up of patients with TOF and ICD through a large nationwide registry. Methods Nationwide Registry including all TOF patients with an ICD initiated in 2010. The primary outcome was the first appropriate ICD therapy. Secondary outcomes included ICD-related complications, heart transplantation, and death. Clinical events were centrally adjudicated by a blinded committee. Cox proportional hazard models were used to identify predictors of appropriate ICD therapies and ICD-related complications. Results A total of 165 patients (mean age 42.2±13.3 years, 70.1% males) were included from 40 centers, including 104 (63.0%) in secondary prevention. During a median (IQR) follow-up of 6.8 (2.5–11.4) years, 78 (47.3%) patients received at least one appropriate ICD therapy, giving an annual incidence of 10.5% (7.1% and 12.5% in primary and secondary prevention, respectively, p=0.03). Overall, 71 (43.0%) patients presented with at least one complication, including inappropriate ICD shocks in 42 (25.5%) patients and lead/generator dysfunction in 36 (21.8%) patients. Among 61 (37.0%) primary prevention patients, the annual rate of appropriate ICD therapies was 4.1%, 5.3%, 9.5%, and 13.3% in patients with respectively no, one, two, or ≥ three guideline-recommended risk factors. In our cohort, QRS fragmentation was the only independent predictor of appropriate ICD therapies (HR 4.34, 95% CI 1.42–13.23), and its integration in a model with current criteria increased the area under the curve from 0.61 to 0.72 (p=0.006). No patient with left ventricular ejection fraction (LVEF) ≤35% without at least one other risk factor had appropriate ICD therapy. Patients with congestive heart failure and/or reduced LVEF had a higher risk of non-sudden death or heart transplantation (HR=11.01, 95% CI: 2.96–40.95). Conclusions Our findings demonstrate high rates of appropriate therapies in TOF patients with an ICD, including in primary prevention. The considerable long-term burden of ICD-related complications, however, underlines the need for careful candidate selection. A combination of easy-to-use criteria might improve risk stratification beyond low LVEF. Freedom from appropriate ICD therapy Funding Acknowledgement Type of funding source: None

Abstract Introduction This retrospective study investigated the long-term follow-up results of medial opening wedge high tibial osteotomy (MOWHTO) with a pre-countered non-locking steel plate implant (Puddu plate = PP) used for medial knee osteoarthrosis (OA) treatment. Materials and methods Consecutive 70 MOWHTOs (66 patients) were performed between 01.01.2004 and 31.12.2008 with the mean follow-up time of 11.4 (SD 4.5; range 1.2–16.1) years. The Kaplan–Meier survival analysis was used to evaluate the cumulative survival of the implant in terms of age (< 50 years old and ≥ 50 years old) and gender. Adverse events were studied and Cox regression analysis was used to evaluate risk factors [age, gender, body mass index (BMI), preoperative mechanical axis, severity of OA, use of bone grafting or substitution and undercorrection of mechanical axis from varus to valgus] for revisions. Results The estimates for the cumulative survival with no need for TKA after MOWHTO were 86% at 5 years, 67% at 10 years and 58% at 16.1 years (SE 0.6, CI 95% 11.1–13.5). A total of 33/70 (47%) adverse events occurred and 38/70 (54%) knees required some revision surgery during the follow-up. Cox regression did not show any statistically significant risk factors for revision. Conclusions The PP has feasible MOWHTO results with a cumulative survival of 67% at 10 years with no need for conversion to TKA. Many adverse events occurred and revision rate due to any reason was high. Age or gender did not have statistically significant differences in terms of survival.

Purpose Luminal breast cancer has a long natural history, with recurrences continuing beyond 10 years after diagnosis. We analyzed long-term follow-up (LTFU) of efficacy outcomes and adverse events in the Breast International Group (BIG) 1-98 study reported after a median follow-up of 12.6 years. Patients and Methods BIG 1-98 is a four-arm, phase III, double-blind, randomized trial comparing adjuvant letrozole versus tamoxifen (either treatment received for 5 years) and their sequences (2 years of one treatment plus 3 years of the other) for postmenopausal women with endocrine-responsive early breast cancer. When pharmaceutical company sponsorship ended at 8.4 years of median follow-up, academic partners initiated an observational, LTFU extension collecting annual data on survival, disease status, and adverse events. Information from Denmark was from the Danish Breast Cancer Cooperative Group Registry. Intention-to-treat analyses are reported. Results Of 8,010 enrolled patients, 4,433 were alive and not withdrawn at an LTFU participating center, and 3,833 (86%) had at least one LTFU report. For the monotherapy comparison of letrozole versus tamoxifen, we found a 9% relative reduction in the hazard of a disease-free survival event with letrozole (hazard ratio [HR], 0.91; 95% CI, 0.81 to 1.01). HRs for other efficacy end points were similar to those for disease-free survival. Efficacy of letrozole versus tamoxifen for contralateral breast cancer varied significantly over time (0- to 5-, 5- to 10-, and > 10-year HRs, 0.62, 0.47, and 1.35, respectively; treatment-by-time interaction P = .005), perhaps reflecting a longer carryover effect of tamoxifen. Reporting of specific long-term adverse events seemed more effective with national registry than with case-record reporting of clinical follow-up. Conclusion Efficacy end points continued to show trends favoring letrozole. Letrozole reduced contralateral breast cancer frequency in the first 10 years, but this reversed beyond 10 years. This study illustrates the value of extended follow-up in trials of luminal breast cancer.

Background: Tetralogy of Fallot (TOF) is the most frequent form of congenital heart disease managed by EP physicians for potential ICD. However, few studies have reported long-term outcomes of TOF patients with ICD. Methods: Between 2005 and 2014, all TOF patients with ICD in 17 French centers were enrolled in a specific evaluation aiming to determine characteristics at implantation as well as outcomes (overall mortality, appropriate ICD therapies, and device-related complications). Results: Overall 78 patients (45±13 years, 64% males) were enrolled. A majority of patients were implanted in the setting of secondary prevention (73%), whereas the remaining (27%) in primary prevention. Among the latest group, known risk factors for sudden cardiac death were: severe pulmonary regurgitation (30%,) prior palliative shunt (50%), syncope with unknown origin (25%), inducible ventricular tachycardia (45%), QRS duration ≥180ms (18%), non-sustained ventricular tachycardia (25%), and documented sustained supra ventricular tachycardia (45%).Overall, patients implanted in the setting of primary prevention presented with a mean of 3.1±1.4 risk factors. After a mean follow-up of 4.9±3.8 years, 35 patients (45%) experienced at least one appropriate therapy (25% in the primary prevention group compared to 53% in the secondary prevention group), giving annual-incidences of 6.9% (95%CI 0.14-13.7) and 21.3% (12.4-30.3) respectively (P=0,01). The mean time between ICD implantation and the first appropriate therapy was 2.2±3.2 years, without significant differences between primary and secondary prevention. Overall, ≥one ICD-related complication occurred in 30 patients (38%), including inappropriate shock (n=9), major pocket hematoma (n=1), lead dysfunction (n=12), infection (n=4), shoulder algodystrophia (n=2), device failure or dislodgement needing reintervention (n=2). Eventually, four patients were transplanted (5%), and six patients (8%) died during the course of follow-up. Conclusions: Considering relatively long-term follow-up, patients with TOF and ICDs experience high rates of appropriate ICD therapies, in both primary and secondary prevention. Major ICD-related complications remain, however, high.
