Project description:The Japanese Catheter Ablation (J-AB) registry, started in August 2017, is a voluntary, nationwide, multicenter, prospective, observational registry, performed by the Japanese Heart Rhythm Society (JHRS) in collaboration with the National Cerebral and Cardiovascular Center using a Research Electronic Data Capture system. The purpose of this registry is to collect the details of target arrhythmias, the ablation procedures, including the type of target arrhythmias, outcomes, and acute complications in the real-world settings. During the year of 2019, we have collected a total of 80 795 procedures (mean age of 65.2 years and 66.4% male) from 425 participant hospitals. Detailed data are shown in Figures and Tables.

Project description:As US health care increasingly focuses on outcomes as a means for quantifying quality, there is a growing demand for risk models that can account for the variability of patients treated at different hospitals so that equitable comparisons between institutions can be made. We sought to apply aspects of prior risk-standardization methodology to begin development of a risk-standardization tool for the National Cardiovascular Data Registry (NCDR) IMPACT (Improving Pediatric and Adult Congenital Treatment) Registry.Using IMPACT, we identified all patients undergoing diagnostic or interventional cardiac catheterization between January 2011 and March 2013. Multivariable hierarchical logistic regression was used to identify patient and procedural characteristics predictive of experiencing a major adverse event after cardiac catheterization. A total of 19,608 cardiac catheterizations were performed between January 2011 and March 2013. Among all cases, a major adverse event occurred in 378 of all cases (1.9%). After multivariable adjustment, 8 variables were identified as critical for risk standardization: patient age, renal insufficiency, single-ventricle physiology, procedure-type risk group, low systemic saturation, low mixed venous saturation, elevated systemic ventricular end-diastolic pressure, and elevated main pulmonary artery pressures. The model had good discrimination (C statistic, 0.70), confirmed by bootstrap validation (validation C statistic, 0.69).Using prior risk-standardization efforts as a foundation, we developed and internally validated a model to predict the occurrence of a major adverse event after cardiac catheterization for congenital heart disease. Future efforts should be directed toward further refinement of the model variables within this large, multicenter data set.

Project description:BackgroundTo analyze the type of ablation procedure, acute outcomes, and complications related to catheter ablation in Japan during the year of 2018.MethodThe Japanese Catheter Ablation (J-AB) registry is a voluntary, nationwide, multicenter, prospective, observational registry, performed by the Japanese Heart Rhythm Society (JHRS) in collaboration with the National Cerebral and Cardiovascular Center using a Research Electronic Data Capture system. The procedural outcome and complications during hospitalizations were collected.ResultA total of 55 525 procedures (mean age of 64.5 years and 66.5% male) from 369 hospitals were collected. The total number of target arrhythmias was 61 610 including atrial fibrillation (AF, 65.6%), atrial flutter (AFL) or atrial tachycardia (16.7%), atrioventricular nodal reentrant tachycardia (7.4%), atrioventricular reentrant tachycardia (3.5%), premature ventricular contractions (4.1%), and ventricular tachycardia (VT, 2.0%). Over a 90% acute success rate was observed among all arrhythmias except for VT due to structural heart disease, and notably, an over 99% success rate was achieved for pulmonary vein isolation of AF and inferior vena cava-tricuspid valve isthmus block for isthmus-dependent AFL. Acute complications during hospitalization were observed in 1558 patients (2.8%), including major bleeding (Bleeding Academic Research Consortium: BARC criteria ?2) in 1.1%, cerebral or systemic embolisms in 0.2%, and death in 0.1%. Acute complications were more often observed with AF ablation (P < .001), especially the first AF ablation session and with structural heart disease (P < .001).ConclusionThe J-AB registry provided real-world data regarding the acute outcomes and complications of ablation for the various types of arrhythmias in Japan.

Project description:BackgroundHybrid revascularization, combining percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG), may be used differently across hospitals. How outcomes compare with multivessel PCI is unknown.MethodsWe studied hybrid revascularization use in patients in the National Cardiovascular Data Registry from 2009 to 2017 who underwent PCI for multivessel coronary artery disease (CAD) at 711 hospitals, excluding patients with prior CABG, acute ST-elevation myocardial infarction, emergency/salvage CABG, or PCI without stent placement. In-hospital mortality associated with hybrid revascularization versus multivessel PCI was compared using a multivariable logistic model.ResultsAmong 775,000 patients with multivessel CAD, 1,126 (0.2%) underwent hybrid revascularization and 256,865 (33%) were treated with multivessel PCI. Although 358 (50.4%) hospitals performed hybrid revascularizations, most (97.3%) performed <1 per year. Most patients (68.7%) treated with hybrid revascularization underwent CABG after PCI; only 79.4% of these patients were discharged on P2Y12 inhibitors. Patients who underwent hybrid revascularization were younger and more likely to have significant left main or proximal left anterior descending disease. Unadjusted in-hospital mortality rates were higher among patients treated with hybrid revascularization than multivessel PCI (1.5% vs 0.9%, P = .02), a difference that was not significant after multivariable adjustment (odds ratio = 1.54, 95% CI = 0.92-2.59).ConclusionsHybrid revascularization remains an infrequently used treatment modality for multivessel CAD. Risk-adjusted in-hospital mortality was no different between hybrid revascularization and multivessel PCI; however, patients who underwent hybrid revascularization were less likely to be discharged on P2Y12 inhibitor therapy despite stent implantation.

Project description:Background Randomized clinical trials have demonstrated that catheter ablation (CA) for atrial fibrillation improves health-related quality of life (HRQoL). In daily practice, however, CA is performed on a wide range of patients, and outcomes may vary. We aimed to examine baseline and 1-year HRQoL outcomes of patients with atrial fibrillation after CA in daily practice. Methods and Results Using a registry-based cohort study designed to recruit patients with atrial fibrillation newly referred to 11 hospitals, we extracted data from 1097 consecutive patients with atrial fibrillation who underwent CA between 2012 and 2019. The Atrial Fibrillation Effects on Quality of Life Overall Summary (AFEQT-OS) was assessed at registration and 1 year after, and a 5-point increase in AFEQT-OS score was considered a meaningful improvement. Overall, the median age was 64 (interquartile range, 56-70) years, 836 (76.2%) were men, and 93.0% (n=1021) of the patients answered the AFEQT questionnaire. The mean AFEQT-OS score was 74.9 (SD, 18.0) at registration and 88.8 (SD, 12.6) at 1 year after. Notably, the incidence of meaningful improvement in HRQoL after CA was 88.6% for the patients with impaired HRQoL (AFEQT-OS score <80), which was only 40.1% in those with preserved HRQoL (AFEQT-OS score ≥80). Female sex, left atrium diameter, and high baseline HRQoL were independently associated with nonimprovement after CA. Conclusions The improvement in HRQoL after CA was similar to that seen in clinical trials; however, one-third of patients did not show improvement. These results underscore the importance of quantitative evaluation of patients' HRQoL to maximize the effect of CA before its performance.

Project description:BACKGROUND:Risk standardization for adverse events after congenital cardiac catheterization is needed to equitably compare patient outcomes among different hospitals as a foundation for quality improvement. The goal of this project was to develop a risk-standardization methodology to adjust for patient characteristics when comparing major adverse outcomes in the NCDR's (National Cardiovascular Data Registry) IMPACT Registry (Improving Pediatric and Adult Congenital Treatment). METHODS:Between January 2011 and March 2014, 39?725 consecutive patients within IMPACT undergoing cardiac catheterization were identified. Given the heterogeneity of interventional procedures for congenital heart disease, new procedure-type risk categories were derived with empirical data and expert opinion, as were markers of hemodynamic vulnerability. A multivariable hierarchical logistic regression model to identify patient and procedural characteristics predictive of a major adverse event or death after cardiac catheterization was derived in 70% of the cohort and validated in the remaining 30%. RESULTS:The rate of major adverse event or death was 7.1% and 7.2% in the derivation and validation cohorts, respectively. Six procedure-type risk categories and 6 independent indicators of hemodynamic vulnerability were identified. The final risk adjustment model included procedure-type risk category, number of hemodynamic vulnerability indicators, renal insufficiency, single-ventricle physiology, and coagulation disorder. The model had good discrimination, with a C-statistic of 0.76 and 0.75 in the derivation and validation cohorts, respectively. Model calibration in the validation cohort was excellent, with a slope of 0.97 (standard error, 0.04; P value [for difference from 1] =0.53) and an intercept of 0.007 (standard error, 0.12; P value [for difference from 0] =0.95). CONCLUSIONS:The creation of a validated risk-standardization model for adverse outcomes after congenital cardiac catheterization can support reporting of risk-adjusted outcomes in the IMPACT Registry as a foundation for quality improvement.

Project description:AimsThe GOLD AF Registry has been designed to prospectively assess the population, indications, and outcomes using second-generation phased radiofrequency (RF) ablation (pulmonary vein ablation catheter GOLD) in a global examination of standard-of-care use for the treatment of paroxysmal and persistent atrial fibrillation (AF).Methods and resultsGOLD AF (NCT02433613) is a prospective, observational, multi-centre registry designed to characterize efficacy and safety of phased RF ablation in patients with AF. The primary endpoint was freedom from AF recurrence at 12-month follow-up after a 90-day blanking period. Ancillary objectives include safety, procedural efficiency, and quality of life (QoL). The QoL assessment using the Atrial Fibrillation Effect on QualiTy-of-Life (AFEQT) and the European Heart Rhythm Association (EHRA) Score of AF-related symptoms was collected at baseline and 12 months. In total, 1054 patients were included in this analysis (age 60.6, 67.6% male, 26.5% PersAF). Kaplan-Meier estimate of freedom from AF recurrence was 77.7% at 12 months. Peri-procedural device or procedure-related complications were observed in 26 (2.5%) patients, with a low stroke rate of 0.3%. One-year post-ablation, the EHRA AF Symptom score decreased in 68% of patients. The AFEQT score improvement was observed in 88.4% and 90.4% of patients who completed the questionnaire in-person or interviewed by phone at 12 month follow-up, respectively.ConclusionPhased RF ablation for the treatment of paroxysmal and persistent AF demonstrated a 77.7% freedom from AF recurrence at 12 months in addition to a significant reduction in arrhythmia symptoms and clinically meaningful improved QoL. Low peri-procedural complication rate of <3% was reported.

Project description:Background:Catheter ablation has become a popular interventional treatment for cardiac tachyarrhythmias and the number has been on the rise year by year. However, little is known about its efficacy and safety in the real-world settings. Method:Japanese Catheter Ablation (J-AB) Registry is a nationwide, multicenter, observational registry, performed by Japanese Heart Rhythm Society (JHRS), collaborated with National Cerebral and Cardiovascular Center. This study is a voluntary nationwide registry and data are collected prospectively using a Research Electronic Data Capture (REDCap) system. Detailed data collection including antiarrhythmic medication is also performed every September. The acute success rate at discharge and the complications associated with ablation procedure will be collected in all cases. Major bleeding events are defined according to Bleeding Academic Research Consortium criteria. Based on the provided information, the annual incidence and predictive factors for outcome will be investigated by the Event Assessment Committee. This registry started in August 2017 and the number of participating medical instructions will be more than 250 hospitals and the target procedure number will be 70 000 per year. We will also compare the results with other registries in foreign countries. Result:The results of this study are currently under investigation. Conclusion:The J-AB registry will provide a real-world data regarding the acute success and complications in Japan, focusing on various types of catheter ablation for cardiac arrhythmias.

Project description:BackgroundLeft atrial appendage occlusion (LAAO) to prevent stroke in patients with atrial fibrillation has been evaluated in 2 randomized trials; post-approval clinical data are limited.ObjectivesThe purpose of this study was to describe the National Cardiovascular Data Registry (NCDR) LAAO Registry and present patient, hospital, and physician characteristics and in-hospital adverse event rates for Watchman procedures in the United States during its first 3 years.MethodsThe authors describe the LAAO Registry structure and governance, the outcome adjudication processes, and the data quality and collection processes. They characterize the patient population, performing hospitals, and in-hospital adverse event rates.ResultsA total of 38,158 procedures from 495 hospitals performed by 1,318 physicians in the United States were included between January 2016 and December 2018. The mean patient age was 76.1 ± 8.1 years, the mean CHA2DS2-VASc (congestive heart failure, hypertension, 65 years of age and older, diabetes mellitus, previous stroke or transient ischemic attack, vascular disease, 65 to 74 years of age, female) score was 4.6 ± 1.5, and the mean HAS-BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly) score was 3.0 ± 1.1. The median annual number of LAAO procedures performed for hospitals was 30 (interquartile range: 18 to 44) and for physicians was 12 (interquartile range: 8 to 20). Procedures were canceled or aborted in 7% of cases; among cases in which a device was deployed, 98.1% were implanted with <5-mm leak. Major in-hospital adverse events occurred in 2.16% of patients; the most common complications were pericardial effusion requiring intervention (1.39%) and major bleeding (1.25%), whereas stroke (0.17%) and death (0.19%) were rare.ConclusionsThe LAAO Registry has enrolled >38,000 patients implanted with the device. Patients were generally older with more comorbidities than those enrolled in the pivotal trials; however, major in-hospital adverse event rates were lower than reported in those trials.

Project description:Pediatric adrenocortical carcinomas (ACCs) are aggressive; the overall survival of pediatric patients with ACCs is 40%-50%. Appropriate staging and histologic classification are crucial as children with incompletely resected tumors or metastatic disease have a dismal prognosis. The clinical course of pediatric adrenocortical tumors (ACTs) is difficult to predict using the current classification schemas, which rely heavily on subjective microscopic and gross macroscopic variables. Recent advances in adult ACT studies have revealed distinct DNA-methylation patterns with prognostic significance that have not been systematically interrogated in the pediatric population.
