BACKGROUND AND OBJECTIVE: Datamining (DM) has, over the last decade, received increased attention in the medical domain and has been widely used to analyze medical datasets in order to extract useful knowledge and previously unknown patterns. However, historical medical data can often comprise inconsistent, noisy, imbalanced, missing and high dimensional data. These challenges lead to a serious bias in predictive modeling and reduce the performance of DM techniques. Data preprocessing is, therefore, an essential step in knowledge discovery as regards improving the quality of data and making it appropriate and suitable for DM techniques...

Introduction: We reviewed our experience with decellularized porcine small intestine sub-mucosa (DPSIS) patch, recently introduced for congenital heart defects. Materials and Methods: Between 10/2011 and 04/2016 a DPSIS patch was used in 51 patients, median age 1.1 months (5 days to 14.5 years), for aortic arch reconstruction (45/51 = 88.2%) or aortic coarctation repair (6/51 = 11.8%). All medical records were retrospectively reviewed, with primary endpoints interventional procedure (balloon dilatation) or surgery (DPSIS patch replacement) due to patch-related complications...

BACKGROUND: The 2013 American College of Cardiology (ACC)/American Heart Association (AHA) cholesterol guideline recommends statin treatment based on patients' predicted atherosclerotic cardiovascular disease (ASCVD) risk. Whether clinician-reported guideline adoption translates to implementation into practice is unknown. OBJECTIVES: We aimed to compare clinician lipid management in hypothetical scenarios versus observed practice. METHODS: The PALM Registry asked 774 clinicians how they would treat 4 hypothetical scenarios of primary prevention patients with: (1) diabetes; (2) high 10-year ASCVD risk (≥7...

Percutaneous coronary intervention in chronic total occlusion is a rapidly evolving area, being considered the last frontier of interventional cardiology. In recent years, the development of new techniques and equipment, as well as the training of specialized personnel, increased their success rates, making it the most predictable procedure available. Although the number of randomized and controlled studies is still limited, results from large multicentered registries allow us to safely offer this intervention to patients, as another treatment option along with the optimized drug treatment and myocardial revascularization surgery...

Trimetazidine (TMZ) is a metabolic agent with significant anti-ischemic properties. By inhibiting the terminal enzyme in the β-oxidation pathway, it shifts the energy substrate metabolism, enhancing glucose metabolism. Thus, it maintains the required energy production with less oxygen consumption, an effect necessary in cases of myocardi. Trimetazidine was recently reaccredited as add-on therapy for symptomatic treatment in patients with stable angina, not adequately controlled or intolerant to first-line therapy...

During the last few years, the number of patients receiving anticoagulant and antiplatelet therapy has increased worldwide. Since this is a chronic treatment, patients receiving it can be expected to need some kind of surgery or intervention during their lifetime that may require treatment discontinuation. The decision to withdraw antithrombotic therapy depends on the patient's thrombotic risk versus hemorrhagic risk. Assessment of both factors will show the precise management of anticoagulant and antiplatelet therapy in these scenarios...

RATIONALE: Dual atrioventricular nodal non-reentrant tachycardia (DAVNNT) is an uncommon arrhythmia. Because of the different refractory periods of fast and slow pathways, a single atrial depolarization gives rise to 2 ventricular activationsthrough fast and slow pathways separately. PATIENT CONCERNS: A 45-year-old woman was referred to our Cardiology Center with symptoms of recurrent palpitations and fatigue persisting for the previous 3 years. On echocardiography, the ejection fraction of the left ventricle was 45%...

INTRODUCTION: The consumption of yerba mate (YM) (Ilex paraguariensis) is common in South America and is now used all over the world. It contains many bioactive substances that can be beneficial. There is also the opinion that it may have harmful effects on heart rhythm, but no studies have been found on this. OBJECTIVE: The aim of this study was to evaluate the acute effect of YM on heart rhythm in patients referred for a Holter study. METHOD: A before and after pseudo-experimental clinical study was conducted by performing a Holter on 50 habitual users of YM, and another one after 24 without YM consumption...

REVIEW
José M Di Diego, Charles Antzelevitch
The J wave syndromes, including the Brugada (BrS) and early repolarization (ERS) syndromes, are characterized by the manifestation of prominent J waves in the electrocardiogram appearing as an ST segment elevation and the development of life-threatening cardiac arrhythmias. BrS and ERS differ with respect to the magnitude and lead location of abnormal J waves and are thought to represent a continuous spectrum of phenotypic expression termed J wave syndromes (JWS). Despite over 25 years of intensive research, risk stratification and the approach to therapy of these two inherited cardiac arrhythmia syndromes are still rapidly evolving...

The false aneurysm of the left ventricle is a rare complication after a mitral valvular surgery. It results from the rupture of the ventricular wall inside an adhering pericardium, thus constituting a cavity whose wall is devoid of myocardial elements and communicates with the ventricle by a large collar. Its clinical presentation remains not very specific with an insidious spontaneous evolution which is generally done towards rupture with sudden death by tamponade. Various sophisticated modern diagnostic techniques allows a precise diagnosis...
