Lead extractions: dissecting adhesions up to the lead-tip of the right ventricle: safety and success-rates.

Aims: Goal of Transvenous Lead Extraction (TLE) is complete removal of all targeted leads, without complications. Despite counter traction manoeuvres, efficacy rates are often hampered by broken right ventricle lead (RV-lead) tips. Mechanically powered lead extraction (Evolution sheath) is effective, however safety of dissection up to the lead tip is unclear.

Advanced image-supported lead placement in cardiac resynchronisation therapy: protocol for the multicentre, randomised controlled ADVISE trial and early economic evaluation.

Introduction: Achieving optimal placement of the left ventricular (LV) lead in cardiac resynchronisation therapy (CRT) is a prerequisite in order to achieve maximum clinical benefit, and is likely to help avoid non-response. Pacing outside scar tissue and targeting late activated segments may improve outcome. The present study will be the first randomised controlled trial to compare the efficacy of image-guided LV lead delivery to conventional CRT implantation.

Long-term outcome of catheter ablation in post-infarction recurrent ventricular tachycardia.

Objectives: Severe LV dysfunction and advanced age are associated with VT recurrence after catheter ablation in patients with post-infarction drug-refractory VT. We present retrospective analysis of long-term outcome after single and repeat VT ablation procedures in patients with ischemic heart disease.

Design: Patients with recurrent VT post infarction who underwent catheter ablation between 2006 and 2017 in Isala Heart Centre were retrospectively analyzed.

Association between pulmonary vein orientation and ablation outcome in patients undergoing multi-electrode ablation for atrial fibrillation.

Background: Previous studies reported on the impact of pulmonary vein orientation on pulmonary vein isolation (PVI) outcome in atrial fibrillation patients undergoing laser balloon PVI and point-by-point radiofrequency ablation.

Objective: Demonstrate the association between pulmonary vein orientation and PVI outcome after multi-electrode radiofrequency ablation.

Methods: 120 patients undergoing PVI with a circular MER catheter were included.

Apical rocking is predictive of response to cardiac resynchronization therapy.

Identification of patients who will benefit from cardiac resynchronization therapy (CRT) is challenging. "Apical rocking" is frequently observed in asynchronously contracting ventricles and small studies suggested that it may predict CRT response. We assessed the predictive value of LV apical rocking on echocardiographic and clinical response to CRT in a large cohort of patients treated with CRT.
