Management of ventricular tachycardia in the ablation era: results of the European Heart Rhythm Association Survey.

Patients with sustained ventricular tachycardia (VT) are at risk of sudden death. Treatment options for VT include antiarrhythmic drug therapy, insertion of an implantable cardioverter-defibrillator, and catheter ablation. Evidence on indications for VT ablation, timing, ablation strategies, and periprocedural management is sparse. The aim of this European Heart Rhythm Association (EHRA) survey was to evaluate clinical practice regarding management of VT among the European countries. An electronic questionnaire was sent to members of the EHRA Electrophysiology Research Network. Responses were received from 88 centres in 12 countries. The results have shown that management of VTs is very heterogeneous across the participating centres. Indications, periprocedural management, and ablation strategies vary substantially. This EP Wire survey has revealed that catheter ablation is the first-line therapy for the treatment of recurrent monomorphic stable VT in patients without structural heart disease as well as in patients with ischaemic cardiomyopathy and impaired left ventricular ejection fraction in the majority of centres. Furthermore, in patients with ischaemic cardiomyopathy and the first episode of monomorphic VT, most centres (62.0%) performed catheter ablation. On the contrary, in patients with non-ischaemic cardiomyopathy, amiodarone (41.4%) and catheter ablation (37.1%) are used in a very similar proportion. Ablation strategies, endpoints, and post-ablation antithrombotic management vary substantially among European centres.

Left atrial appendage occluder implantation in Europe: indications and anticoagulation post-implantation. Results of the European Heart Rhythm Association Survey.

The aim of this EP Wire survey was to assess the indications and anticoagulation strategies post-left atrial appendage occluder (LAAO) implantation for stroke prevention in patients with non-valvular atrial fibrillation in Europe. A total of 33 centres in 13 European countries completed the survey. All centres were members of the European Heart Rhythm Association Electrophysiology Research Network. Left atrial appendage occluder procedures were performed by electrophysiologists in 52% of the centres and by interventional cardiologists in the remaining centres. The EP Wire survey has revealed that the most common indications for LAAO are stroke prevention in patients at high thrombo-embolic risk and absolute contraindications to oral anticoagulation (OAC) therapy or a history of bleeding. Early- and long-term post-implantation anticoagulation strategies in patients with and without device thrombosis were very heterogeneous between centres with most strategies not being supported by the randomized trials. In patients without contraindications to OAC, 41% of the centres would prescribe no therapy at all after 6 months following LAAO implantation. In patients with LAA thrombus during follow-up and patients with absolute contraindications to OAC, management was highly heterogeneous and included aspirin, clopidogrel, non-vitamin K antagonist oral anticoagulants, low molecular weight heparin, surgery, unfractionated heparin, or no therapy.
