          Supraventricular tachycardias (SVTs) are common arrhythmic conditions in clinical practice. Increased knowledge and experience on SVTs and some unclear situations in clinical practice led the European Society of Cardiology (ESC) team to write a new guideline. In this review, we touch upon the important points in the new ESC 2019 SVT guidelines and present changing approaches and suggestions. By providing a general review on SVTs, we also mention the basic mechanism, epidemiology, and clinical presentation of SVTs, approaching narrow and wide QRS tachycardias, SVTs in special patient groups, and treatment of SVTs.

            Incidence and predictors of major complications from contemporary catheter ablation to treat cardiac arrhythmias.

            Updated understanding of the risks of catheter ablation is important because techniques have evolved for procedures treating non-life-threatening as well as potentially lethal arrhythmias. This prospective study sought to assess the incidence and predictors of major complications from contemporary catheter ablation procedures at a high-volume center. Over a 2-year period, 1,676 consecutive ablation procedures were prospectively evaluated for major complications throughout 30 days postprocedure. Predictors of major complications were determined in a multivariate analysis adjusted for demographics, clinical variables, ablation type, and procedural factors. Rates of major complications differed between procedure types, ranging from 0.8% for supraventricular tachycardia, 3.4% for idiopathic ventricular tachycardia (VT), 5.2% for atrial fibrillation (AF), and 6.0% for VT associated with structural heart disease (SHD). Ablation type (ablation for AF [odds ratio (OR) 5.53, 95% confidence interval (CI) 1.81 to 16.83], for VT with SHD [OR 8.61, 95% CI 2.37 to 31.31], or for idiopathic VT [OR 5.93, 95% CI 1.40 to 25.05] all referenced to supraventricular tachycardia ablation), and serum creatinine level >1.5 mg/dl (OR 2.48, 95% CI 1.07 to 5.76) were associated with increased adjusted risk of major complications, whereas age, gender, body mass index, international normalized ratio level, hypertension, coronary artery disease, diabetes, and prior cerebrovascular accident were not associated with increased risk. In a large cohort of contemporary catheter ablation, major complication rates ranged between 0.8% and 6.0% depending on the ablation procedure performed. Aside from ablation type, renal insufficiency was the only independent predictor of a major complication. Copyright © 2011 Heart Rhythm Society. Published by Elsevier Inc. All rights reserved.

              Incidence and predictors of atrial flutter in the general population.

              The goal of our study was to determine the incidence and predictors of atrial flutter in the general population. Although atrial flutter can now be cured, there are no reports on its epidemiology in unselected patients. The Marshfield Epidemiological Study Area (MESA), a database that captures nearly all medical care among its 58,820 residents was used to ascertain all new cases of atrial flutter diagnosed from July 1, 1991 to June 30, 1995. To identify predisposing risk factors, we employed an age- and gender-matched case-control study design using eight additional variables. A total of 181 new cases of atrial flutter were diagnosed for an overall incidence of 88/100,000 person-years. Incidence rates ranged from 5/100,000 in those <50 years old to 587/100,000 in subjects older than 80. Atrial flutter was 2.5 times more common in men (p < 0.001). The risk of developing atrial flutter increased 3.5 times (p < 0.001) in subjects with heart failure and 1.9 times (p < 0.001) for subjects with chronic obstructive pulmonary disease. Among those with atrial flutter 16% were attributable to heart failure and 12% to chronic obstructive lung disease. Three subjects (1.7%) without identifiable predisposing risks were labeled as having "lone atrial flutter." This study, the first population-based investigation of atrial flutter, suggests this curable condition is much more common than previously appreciated. If our findings were applicable to the entire U.S. population, we estimate 200,000 new cases of atrial flutter in this country annually. At highest risk of developing atrial flutter are men, the elderly and individuals with preexisting heart failure or chronic obstructive lung disease.
