RESUMEN
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. METHODS AND RESULTS: The total of 482 consecutive patients (Abbott Amulet N = 93 and Boston Scientific Watchman N = 389) were included in the periinterventional analyses. After 6 weeks, 353 patients completed the first follow-up including transoesophageal echocardiography (TEE) (73.2%). Successful LAAC could be performed in more than 94%. The complication rate does not significantly differ between device types (p = 0.92) according to Fischer test and comprised 2.2% in the Amulet and 2.3% in the Watchman group. The kind of device and the frequency of LAAC per study center had no influence on the success and complication rates. Device related thrombus could be revealed more frequently in the Watchman group (4.5%) than in the Amulet group (1.4%) but this difference is still not significant in Fisher test (p = 0.14). Same conclusion can be made about residual leakage 1.1% versus 0% [not significant in Fisher test (p = 0.26)]. Dual antiplatelet therapy followed the intervention in 64% and 22% of patients were discharged under a combination of an anticoagulant (VKA/DOAC/Heparin) and one antiplatelet agent. CONCLUSIONS: The ORIGINAL registry supports the thesis from large, randomized trials that LAAC can be performed with a very high procedural success rate in the everyday clinical routine irrespective of the used LAA device (Watchman or Amulet). The postprocedural antithrombotic strategy differs widely among the participating centers.

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.

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. The overall mortality of these patients was 4.2%. The presence of a patent internal thoracic artery-graft at the time of reoperation was not a risk factor for higher morbidity and mortality. Revascularization with percutaneous transluminal coronary angioplasty of the internal thoracic artery or the native left anterior descending artery via the internal thoracic artery-graft used as a conduit was performed in 327 patients. The primary success rate was 87%, the angiographically assessed rate of restenosis was 30% and the rate of complications approximately 1%. CONCLUSIONS: In spite of technical problems the percutaneous transluminal coronary angioplasty in or via internal thoracic artery-graft presents a safe and feasible option to be recognized before a potential reoperation.
