An observational study in Atrioventricular Reentrant Tachycardias and Wolff-Parkinson-White (WPW) Syndrome, sponsored by IRCCS Ospedale San Raffaele. Not yet recruiting. Open to participants aged 5 Years to 60 Years. Per ClinicalTrials.gov, last updated 2026-02-27.
Sponsored by IRCCS Ospedale San Raffaele · Observational
The aim of this observational, retrospective study is to evaluate, comparatively, procedural outcomes of APs (Accessory pathway) ablation according to the conduction properties (i.e., manifest vs. concealed) and to assess both short- and long-term outcomes of RFA (RF ablation).
23 studies on the registry are indexed under Tachycardia, Atrioventricular Nodal Reentry; 5 are open to participants now.

Patients who consecutively underwent an electrophysiological (EP) study at San Raffaele Scientific Institute for EP study due to paroxysmal SVT with documented acessory pathway
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Patients who consecutively underwent an electrophysiological (EP) study between 2005 and 2023 at San Raffaele Scientific Institute are included if they met one of the following criteria:
Patients referred for EP study due to:
The presence of high-risk electrophysiological features (e.g., short antegrade effective period of the AP, rapid conduction during atrial fibrillation), or Induction of sustained AVRT during the EP study.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
