Data sharing: A new editorial initiative of the International Committee of Medical Journal Editors. Implications for the editors' network.

The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship -emphasizing the importance of responsibility and accountability-, have been proposed.

Previous percutaneous coronary intervention as risk factor for coronary artery bypass grafting.

Background: Percutaneous coronary intervention (PCI) has increased as the initial revascularization strategy in chronic coronary artery disease. Consequently, more patients undergoing coronary artery bypass grafting (CABG) have history of coronary stent.

Objective: Evaluate the impact of previous PCI on in-hospital mortality after CABG in patients with multivessel coronary artery disease.

Evaluation of surgical treatment of congenital heart disease in patients aged above 16 years.

Background: The increasing number of children with evolving congenital heart diseases demands greater preparation of professionals and institutions that handle them.

Objective: To describe the profile of patients aged over 16 years with congenital heart disease, who have undergone surgery, and analyze the risk factors that predict hospital mortality.

Method: One thousand five hundred twenty patients (mean age 27 ± 13 years) were operated between January 1986 and December 2010.

Pulmonary root translocation in malposition of great arteries repair allows right ventricular outflow tract growth.

Objective: Optimal surgical treatment of patients with transposition of the great arteries (TGA), ventricular septal defect (VSD), and pulmonary stenosis (PS) remains a matter of debate. This study evaluated the clinical outcome and right ventricle outflow tract performance in the long-term follow-up of patients subjected to pulmonary root translocation (PRT) as part of their surgical repair.

Methods: From April 1994 to December 2010, we operated on 44 consecutive patients (median age, 11 months).

Conventional versus biventricular pacing in heart failure and bradyarrhythmia: the COMBAT study.

Background: Worsening in clinical and cardiac status has been noted after chronic right ventricular pacing, but it is uncertain whether atriobiventricular (BiVP) is preferable to atrio-right ventricular pacing (RVP). Conventional versus Multisite Pacing for BradyArrhythmia Therapy study (COMBAT) sought to compare BiVP versus RVP in patients with symptomatic heart failure (HF) and atrioventricular (AV) block.

Methods And Results: COMBAT is a prospective multicenter randomized double blind crossover study.

Radiofrequency ablation of paroxysmal atrial fibrillation: factors determining long-term clinical efficacy.

Background: Most of the studies on this subject have reported predictors of recurrence of atrial fibrillation after catheter ablation with relatively short follow-up periods.

Objective: To retrospectively evaluate predictors of long-term recurrence of paroxysmal atrial fibrillation (AF) in patients undergoing pulmonary vein isolation following one single procedure.

Methods: The authors studied a total of 139 patients (102 men; mean age of 55 +/- 12 years) undergoing radiofrequency ablation using the ostial or extra-ostial techniques for left atrial approach, combined or not with cavotricuspid isthmus ablation (CTI).

The cone reconstruction of the tricuspid valve in Ebstein's anomaly. The operation: early and midterm results.

Objectives: We sought to describe a new technique for tricuspid valve repair in Ebstein's anomaly and to report early echocardiographic results, as well as early and midterm clinical outcomes.

Methods: From November 1993 through August 2005, 40 consecutive patients with Ebstein's anomaly (mean age, 16.8 +/- 12.

Normalization of right ventricular performance and remodeling evaluated by magnetic resonance imaging at late follow-up of heart transplantation: relationship between function, exercise capacity and pulmonary vascular resistance.

Background: Right ventricular (RV) dysfunction remains one of the most prominent complications during the period immediately after heart transplantation (HT); however, late adaptation of the RV has not been well described. The aim of our study was to evaluate RV function and remodeling using magnetic resonance imaging (MRI) and to correlate it with exercise capacity and also with hemodynamic data obtained before HT.

Methods: We prospectively evaluated RV function of 25 heart-transplanted patients, without cardiac allograft vasculopathy, who were documented by negative dobutamine stress echocardiography during late follow-up (Group 1, 6 +/- 4.
