Abstract

Background The prevalence of Wolff-Parkinson-White (WPW) syndrome varies between 0.68 and 1.7/1000. The epidemiological profile may be modified after the introduction of transcatheter interventions.Objectives The aim of this study is to investigate the epidemiological trends of the WPW syndrome in a general population during a period with available and reimbursed transcatheter ablation.Methods and results Data of WPW patients <50 years old were retrieved from our national database (2000-2010). We identified 6086 (61% male) patients, accounting for an overall prevalence of 0.36/1000 with a peak of 0.61/1000 in ages 20-24 years. The risk of death and sudden death was 0.071% and 0.02% per patient-year, respectively. The 42 deaths occurred at a median age of 29 years. Associated congenial heart disease was noted in 158 (2.6%) patients, including 42 with Ebstein's anomaly that increased the mortality risk (P=0.001, OR=8.5). In those without congenital heart disease, myocardial dysfunction occurred in 115 (1.9%) patients and increased the risk of death (P<0.001, OR=10.6) and sudden death. Radiofrequency catheter ablation was performed in 2527 patients at a median age of 25.7 years (4.54% per patient-year, discharge mortality 0.16%); 11 (0.4%) before the age of 5, and 2231 (88%) after the age of 15. Whereas repeated ablation procedures accounted for 6.0% of the procedures, those in Ebstein's patients were 25%.Conclusion Radiofrequency catheter ablation is already a common treatment for WPW patients, particularly during young adulthood, which accounts for a lower prevalence. Myocardial dysfunction and associated congenital heart disease remain as risks of mortality.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
