BACKGROUND: Transcatheter device closure has become the established standard of care for suitable atrial septal defects. Device erosion has been a recent focus and has prompted changes in the Instructions for Users documentation released by device companies. We reviewed our entire local experience with atrial septal defect device closure, focussing on the evolution of this procedure in our centre and particularly on complications. METHODS: We carried out a retrospective review of 581 consecutive patients undergoing attempted transcatheter device closure of an atrial septal defect in Auckland from December 1997 to June 2014...

BACKGROUND: After left atrial appendage closure (LAAC), various antithrombotic protocols have been suggested, but the optimal post-procedural antithrombotic strategy is still under debate. AIMS: To investigate the efficacy and safety of LAAC with an AMPLATZER™ Cardiac Plug (ACP) device (St. Jude Medical, Minneapolis, MN, USA) followed by single antiplatelet therapy. METHODS: Consecutive patients with non-valvular atrial fibrillation and a contraindication for oral anticoagulants who underwent LAAC with an ACP device between 2012 and 2014 in two French centres were included...

Atrial septal defect (ASD) is one of the most common congenital heart defects requiring procedural intervention. In such cases, transcatheter closure of secundum ASDs has been demonstrated to be safe and effective in both children and adults, with similar success and complication rates to surgery. However, appropriate patient selection and an accurate device selection is mandatory to prevent serious complications such as ventricular arrhythmias, outflow tract obstruction of the left and right ventricle, or ischemic events secondary to the obstruction of blood flow due to device embolization...

AIMS: We evaluated the utility of computerized tomography (CT) with respect to sizing work-up for percutaneous left atrial appendage (LAA) closure, and implications for procedural safety and outcomes. METHODS AND RESULTS: Contrast-enhanced multi-detector CT was routinely conducted to guide sizing for LAA closure in addition to transoesophageal echocardiography (TOE). Procedural safety and efficacy were prospectively assessed. Across 73 consecutive cases there were no device-related procedural complications, and no severe leaks...

Patients with atrial fibrillation (AF) are at risk for stroke and thromboembolism. Oral anticoagulants (OAC) are effective therapies to reduce the risk of stroke; however these agents also increase the risk of bleeding complications. Concerns over bleeding contribute to significant under treatment and leave a substantial proportion of patients at risk for a serious or life-threatening stroke. Identification of the left atrial appendage (LAA) as the major site of pathogenic thrombus formation in AF patients has led to the development of devices which exclude the appendage from systemic circulation...

AIMS: To compare in a observational study acute and 12-month results of percutaneous closure of patent foramen ovale (PFO) with two occluder devices. METHODS AND RESULTS: Between June 2007 and October 2014, 406 consecutive patients (48.1±13.3 years, 243 women) underwent percutaneous PFO closure either with the Amplatzer (n=179) or the Figulla (n=227) device after a stroke or a transient ischemic attack ascribed to the PFO. A right-to- left shunt grade >1 was previously detected in all patients and atrial septal aneurysm was present in 111 (27...

: Atrial fibrillation (AF), with a prevalence of 1% to 2%, is the most common cardiac arrhythmia. Without antithrombotic treatment, the annual risk of a cardioembolic event is 5% to 6%. The source of a cardioembolic event is a thrombus, which is usually formed in the left atrial appendage (LAA). Prevention of cardioembolic events involves treatment with anticoagulant drugs: either vitamin K antagonists or, recently, novel oral anticoagulants (NOAC). The other (nonpharmacologic) option for the prevention of a cardioembolic event involves interventional occlusion of the LAA...

AIMS: Percutaneous left atrial appendage closure (LAAC) is a valuable treatment option for stroke prevention in patients with atrial fibrillation and a HAS-BLED-Score ≥3. Determinants of procedural safety events and neurological outcome of the patients with the Occlutech device (OD) are not established yet. METHODS AND RESULTS: Between 2012 and 2016, 30 patients underwent LAAC using the OD. This is a prospective study. Neurological examination and transesophageal echocardiography was performed directly before and after the procedure and after 1, 3, and 12 months...

PURPOSE OF REVIEW: The authors reviewed the seminal and more recent literature surrounding the major modalities for percutaneous left atrial appendage closure used in contemporary practice, with particular emphasis on safety and efficacy, technical challenges, and future developments. RECENT FINDINGS: Along with the continued practice of surgical left atrial appendage closure, which has evolved substantially with the advent of clipping techniques, a number of percutaneous methods have been developed to close the left atrial appendage with endocardial, epicardial, and hybrid approaches...

Left atrial appendage (LAA) dimensions have been shown as an independent predictor of higher risk for stroke in AF patients. Little data exist on the outcomes after LAA closure in patients with nonvalvular atrial fibrillation (NVAF) who have relatively bigger LAA size. This study aims to evaluate the results associated with LAA closure with the Amplatzer cardiac plug (ACP, AGA, St. Jude Medical, Minneapolis, MN) in bigger LAA size. A total of 25 patients with NVAF underwent LAA closure with the ACP device. All patients received short-term (up to 3 months) dual-antiplatelet therapy (clopidogrel and aspirin) after the procedure and aspirin only thereafter...

REVIEW
Takahiro Shiota
Catheter-based treatment of valvular heart disease, such as transvalvular aortic valve replacement (TAVR) or mitral clip procedure, has been increasingly accepted as a treatment choice for the past several years. Such new treatment options have been changing the management of patients with valvular heart disease drastically while socio-economic factors regarding their application need to be taken into consideration. The use of echocardiography, including transesophageal echocardiography (TEE), for such catheter-based treatments is essential for the success of the procedures...

Left atrial appendage closure with the WATCHMAN device is an alternative to chronic oral anticoagulation for thromboembolic prophylaxis in atrial fibrillation patients. Left atrial device-related thrombus (DRT) has been described in the first year after implant with an incidence of ~6%. A 79-year-old man underwent WATCHMAN device placement in 2006. Routine protocol specified follow-up transesophageal echocardiograms (TEE) at 6 weeks, 6 months, and 1 year following implant showed no evidence for DRT or peri-device flow...
