Clinical and Research Interest

Clinical interest

  • Main areas of clinical interest include the management (invasive and non-invasive) of cardiac arrhythmias, the whole spectrum of ablation procedures (including complex ablations of atrial fibrillation and ventricular tachyarrhythmias) as well as implantation of all types of cardiac rhythm management devices.

Research interest

Main areas of research interest include

  • Cardiac arrhythmia ablation procedures (mainly  atrial fibrillation and atrial tachycardias post atrial fibrillation ablation)  – relevant publications in peer-reviewed medical journals and original description of a novel ablation strategy for the invasive management of perimitral flutter [modified anterior line – J Cardiovasc Electrophysiol. 2010;21(6):665-70].

  • Implantable cardiac rhythm management devices. Collaborator in a prospective, randomized, multcenter study  evaluating the efficacy of an insertable cardiac monitor in the detection of atrial fibrillation after cryptogenic stroke [CRYSTAL AF – N Engl J Med 2014;370(26):2478]

  • Alternate pacing sites –  several publications in peer-reviewed journals on midseptal pacing

  • Anticoagulant agents in atrial fibrillation. Primary investigator in a prospective, multicenter, nationwide, cross-sectional study evaluating the pattern of anticoagulation in elderly patients older than 80 years (PAVE-AF study– principal ivestigator).
