One person in 450 has a congenital condition, the Wolff-Parkinson-White (WPW), that 'heart problems. Surgical treatment, according to the guidelines, and 'used only in those who have already' had symptoms of arrhythmia; but now a study has shown that patients without symptoms are those in more 'high risk, and should be operated to prevent sudden death. The research 'was published in Circulation by Carlo Pappone, expert Maria Cecilia Hospital in Cotignola (Ravenna). WPW syndrome mainly affects males (70%), especially during adolescence; in the heart of the patients there are abnormal electrical circuits that are 'crazy' heart rate and increase the risk of arrhythmias: these in most cases are benign, but in rare cases are life-threatening. "The syndrome - experts say - you can 'diagnose with a simple electrocardiogram and can' be cured by performing the ablation, which consists of a small burn of these circuits abnormal". The problem, they add, and 'that to date international guidelines "deny the possibility' to perform ablation in patients with no symptoms, even if they have WPW syndrome". Yet, according to the study of Maria Cecilia Hospital, "these patients are potentially even more 'high risk of symptomatic". The study and 'lasted eight years and has examined more than 2 thousand patients. "The results completely change the point of view of this disease - says pimp - and after this discovery, many children can be saved from the risk of sudden death. We recommend to enable screening programs in all schools to identify as' soon, through a simple ECG, asymptomatic children with WPW syndrome and at risk of life-threatening arrhythmias. "
