BACKGROUND: Development of electroanatomical systems make it possible to perform ablations without the use of fluoroscopy. The aim of this study was to evaluate the efficacy and safety of cryoablation procedures without the use of fluoroscopy. METHODS: The study group consisted of 45 patients (14 female; age 36 ± 15 years) treated with cryoablation using the EnSite electroanatomical system: 10 with ventricular extrasystoly from the right ventricle, 6 with the arrhythmogenic site near the left coronary artery, 17 patients with Wolff-Parkinson-White syndrome (WPW), 2 patients with atrioventricular nodal reentrant tachycardia (AVNRT) type 2, 7 patients with AVNRT type 1, 3 patients with atrial tachycardia...

Aims: The long-term outcomes of radiofrequency catheter ablation (RFCA) in patients with Wolff-Parkinson-White syndrome (WPW) remain unclear. We investigated the impact of RFCA on the long-term risk of coronary events and mortality in WPW patients. Methods and results: We conducted a prospective cohort study utilizing the Taiwan National Health Insurance Research Database. Between 2000 and 2003, WPW patients with no prior coronary artery disease (CAD) history, aged over 18 years, who underwent RFCA were identified...

We report a case of a patient with right axillary ventricular. Similar congenital anomaly of the right atrium was reported as "right appendage diverticulum or right atrial diverticulum". However, this independent chamber has its own annulus, synchronizes with the right ventricular, and generates large ventricular potential. Under the guidance of CARTO mapping system, a right atrioventricular accessory pathway associated with Type B Wolff-Parkinson-White syndrome was ablated successfully. This pathway was close to the annulus of the axillary ventricular...

Implantable cardioverter-defibrillator (ICD) is the gold standard therapy for the prevention of sudden cardiac death. Nevertheless, ICD placement in the paediatric population is still limited because of several technical difficulties. Several implantation techniques have been proposed but experience in infants with very low weight and less than 6 months is very limited. We herein describe a case of a minimally invasive ICD epicardial implantation in a 4-month-old infant weighing 5 kg. A diagnosis of arrhythmic cardiomyopathy with left ventricular non-compaction disease with ventricular tachycardia storms, QT prolongation and Wolff-Parkinson-White pattern was made...

BACKGROUND: Risk stratification for Wolff-Parkinson-White (WPW) pattern either by non-invasive or invasive tests is important to determine whether an ablation is necessary or not. The aim was to compare non-invasive tests and invasive studies in a pediatric WPW population. METHODS: A total of 71 WPW patients [median age 14 years (IQR 11 - 16 years); 43 male] underwent Holter monitoring, exercise stress test (EST), and transesophageal electrophysiological study (TEEPS)...

BACKGROUND: Data on children with left ventricular non-compaction (LVNC) is sparse. The purpose of this study was to evaluate its clinical profiles in a population of Chinese children. METHODS: From January 2010 to March 2016, consecutive Chinese children (aged <18 years) with LVNC diagnosed by cardiovascular magnetic resonance (CMR) were prospectively recruited at Fuwai Hospital. RESULTS: A total of 41 Chinese children (male: 28%; mean age: 14±4years) were included in this study...

Aims: Our aim was to describe the electrocardiographic findings of a large sample of Spanish workers from several different employment sectors. Methods and results: Between May 2008 and November 2010, 13 495 consecutive 12-lead resting electrocardiograms (ECGs) were obtained during health examinations of working adults aged 16-74 years in 5 cities in different regions of Spain. Of those, 13 179 ECGs suitable for interpretation were included in this study. All tracings were classified by the same cardiologist, according to the Minnesota Code criteria...

BACKGROUND: The micro waveform of His bundle potential can't be recorded beat-to-beat on surface electrocardiogram yet. We have found that the micro-wavelets before QRS complex may be related to atrioventricular conduction system potentials. This study is to explore the possibility of His bundle potential can be noninvasively recorded on surface electrocardiogram. METHODS: We randomized 65 patients undergoing radiofrequency catheter ablation of paroxysmal superventricular tachycardia (exclude overt Wolff-Parkinson-White syndrome) to receive "conventional electrocardiogram" and "new electrocardiogram" before the procedure...

Purpose The aim of this study was to determine whether the exercise tolerance test can provide diagnostic and prognostic information regarding children and young adults and help predict outcome. METHODS: A total of 87 patients, aged 7-29 years (median 13, mean 13.4) were selected retrospectively. They underwent exercise test at the Freeman Hospital from December, 2015 to May, 2016. There were two groups of patients - 46 had symptoms such as chest pain, palpitations, syncope, or dyspnoea on exertion and no cardiac diagnosis, and 40 patients had a cardiac diagnosis such as hypertrophic cardiomyopathy, transposition of the great arteries with post-arterial switch operation, aortic stenosis or regurgitation, tetralogy of Fallot, abnormal coronary arteries, Wolff-Parkinson-White syndrome, or supraventricular tachycardia...

The delta wave remains an important indicator to diagnose the WPW syndrome. In this paper, a new method of detection of delta wave in an ECG signal is proposed. Firstly, using the continuous wavelet transform, the P wave, the QRS complex and the T wave are detected, then their durations are computed after determination of the boundary location (onsets and offsets of the P, QRS and T waves). Secondly, the PR duration, the QRS duration and the upstroke of the QRS complex are used to determine the presence or absence of the delta wave...

REVIEW
Susan S Kim, Bradley P Knight
For years, conventional wisdom has held that patients with asymptomatic ventricular pre-excitation (asymptomatic WPW or WPW pattern) were at low risk for adverse outcomes. This assumption has been challenged more recently in a number of observational/natural history studies as well as in prospective trials in which patients were more aggressively studied via invasive electrophysiology study (EPS) and more aggressively treated, in some cases, with pre-emptive catheter ablation, despite the lack of symptoms. In sum, the data do not definitively support one approach (early, up-stream EPS and/or ablation) vs...

INTRODUCTION: Wolff-Parkinson-White (WPW) pattern is occasionally found in asymptomatic aviators during routine ECGs. Aeromedical concerns regarding WPW pattern include risk of dysrhythmia or sudden cardiac death (SCD), thus affecting the safety of flight. The purpose of this study was to determine the prevalence and outcomes of aviators with asymptomatic WPW pattern and assess for risk factors that contribute to progression to dysrhythmia or symptoms. METHODS: The U...

CONTEXT: Olympic athletes represent model of success in our society, by enduring strenuous conditioning programmes and achieving astonishing performances. They also raise scientific and clinical interest, with regard to medical care and prevalence of cardiovascular (CV) abnormalities. OBJECTIVE: Our aim was to assess the prevalence and type of CV abnormalities in this selected athlete's cohort. DESIGN, SETTING AND PARTICIPANTS: 2352 Olympic athletes, mean age 25±6, 64% men, competing in 31 summer or 15 winter sports, were examined with history, physical examination, 12-lead and exercise ECG and echocardiography...
