Short term outcome after left atrial appendage occlusion with the AMPLATZER Amulet and WATCHMAN device: results from the ORIGINAL registry (saxOnian RegIstry analyzinG and followINg left atrial Appendage cLosure).

Background: Various randomized multicenter studies have shown that percutaneous left atrial appendage closure (LAAC) is not inferior in stroke prevention compared to vitamin K antagonists (VKA) and can be performed safely and effectively.

Aims: The prospective multicenter ORIGINAL registry in the Free State of Saxony (saxOnian RegIstry analyzinG and followINg left atrial Appendage cLosure) investigated the efficiency and safety of LAAC with Watchman or Amulet device in a real word setting. A special focus was put on the influence of LAAC frequency on periprocedural efficiency and safety.

Circumferential pulmonary vein ablation for treatment of atrial fibrillation using an irrigated-tip catheter.

In this study, a series of 52 consecutive patients with atrial fibrillation from 1 institution underwent circumferential pulmonary vein ablation using an irrigated-tip catheter. The technique was safe, and 81% of the patients maintained sinus rhythm at 6 months. However, 1/3 of them required additional antiarrhythmic drug therapy.

Angioplasty of the internal thoracic artery bypass-graft an alternative to reoperation.

Background: This review presents an overview of interventional revascularization procedures of the internal thoracic artery after prior implantation as a coronary-artery bypass graft.

Methods: Our search was concentrated on the MEDLINE-database to identify all articles on internal thoracic artery-graft-angioplasties and reoperation after internal thoracic artery bypass grafting published between 1968 and 2000.

Results: Surgical revascularization and reoperation were reported in five papers including a total of 785 patients.
