BACKGROUND: Closure of the left atrial appendage (LAA) to prevent cardioembolic events is an alternative therapy to oral anticoagulation in patients with non-valvular atrial fibrillation. The LAA is an important source of natriuretic peptides and its exclusion from the circulation may alter the blood level of these hormones, thereby influencing their diagnostic value and clinical effects. METHODS: We aimed to prospectively assess potential changes in mid-regional pro A-type natriuretic peptide (MR-proANP) and N-terminal pro B-type natriuretic peptide (NT-proBNP) levels six weeks and six months after interventional LAA closure using the Watchman device...

BACKGROUND: Left atrial appendage occlusion (LAAO) has been proven to be effective for stroke prophylaxis in patients with non-valvular atrial fibrillation (NVAF). We aim to assess the safety and efficacy of LAAO by AMPLATZER™ devices in a large, multicenter, single-nation cohort of NVAF patients at high-risk of stroke and bleeding. METHODS: From December 2008 to April 2015 613 NVAF patients (75.1±8.0years, 62.5% male) underwent LAAO in 15 Italian centers by AMPLATZER™ devices...

OBJECTIVES: Accurate sizing of the left atrial appendage (LAA) is essential when performing percutaneous LAA closure. This study aimed to compare different LAA imaging modalities and sizing methods in order to obtain successful LAA closure. BACKGROUND: Percutaneous LAA closure is an increasingly used treatment strategy to prevent stroke in patients with atrial fibrillation. LAA sizing has typically been done by 2D-transoesophageal echocardiography (TEE). METHODS: Patients who had a preprocedural TEE and preprocedural and postprocedural multislice CT (MSCT) were identified...

Atrial fibrillation (AF) is the most common arrhythmia and its prevalence is increasing due to the progressive aging of the population. About 20% of strokes are attributable to AF and AF patients are at five-fold increased risk of stroke. The mainstay of treatment of AF is the prevention of thromboembolic complications with oral anticoagulation therapy. Drug treatment for many years has been based on the use of vitamin K antagonists, but recently newer and safer molecules have been introduced (dabigatran etexilate, rivaroxaban, apixaban, and edoxaban)...

A 31-year-old patient with a univentricular heart and double-inlet left ventricle, moderate pulmonary stenosis, and severe mitral valve regurgitation experienced irreversible heart failure after mitral valve replacement. "Biventricular" mechanical circulatory support was initiated. The systemic circulation was supported using the HeartWare ventricular assist device (HVAD) (HeartWare, Framingham, MA) pump in the usual manner. The second pump was inserted into the right atrium and connected to the pulmonary artery after closure of the pulmonary valve and atrial separation...

Left atrial appendage (LAA) closure for stroke prevention in the setting of non valvular atrial fibrillation is an alternative to oral anticoagulation in patients with increased bleeding risk. It allows similar reduction in thromboembolic events, in particular stroke, compared to warfarin. A common clinical dilemma is the management of patients with peri-device leak after LAA occlusion. This has been documented in both percutaneous as well as with surgical approaches. The specific definitions of leak severity, and the longer term clinical implications are poorly understood...

AIMS: Device sizing for LAA closure using transesophageal echocardiography (TEE) can be challenging due to complex LAA anatomy. We investigated whether the use of 3D-printed left atrial appendage (LAA) models based on pre-procedural computed tomography (CT) permits accurate device sizing. METHODS AND RESULTS: 22 patients (73±8 years, 55% male) with atrial fibrillation requiring anticoagulation at high bleeding risk underwent LAA closure (WatchmanTM device). Pre-procedurally, LAA was sized by TEE and third-generation dual-source CT...

Left ventricle-right atrial communication could be congenital (Gerbode defect) or acquired as a complication of surgery or infective endocarditis and leads to volume overloading of pulmonary circulation. Two types, direct and indirect types are known depending on the involvement of septal tricuspid leaflet. Transcatheter closure of this defect is feasible and appears an attractive alternative to surgical management. Various devices like Amplatzer duct occluder I, II, Muscular ventricular septal defect device etc...

BACKGROUND: Oral anticoagulants (OACs) reduce stroke risks with nonvalvular atrial fibrillation (AF); however, they are underused because of absolute or relative contraindications due to real or perceived risk of bleeding. Although left atrial appendage closure is increasingly performed in OAC-ineligible patients, this has not been studied in a randomized controlled trial. STUDY OBJECTIVES: The ASAP-TOO study is designed to establish the safety and effectiveness of the Watchman left atrial appendage closure device in patients with nonvalvular AF who are deemed ineligible for OAC...

A 39-year-old woman underwent uneventful percutaneous occlusion of an ostium secundum atrial septal defect (ASD) with a 22 mm Ultrasept ASD Occluder(®). Transesophageal echocardiography (TEE) performed two years after implantation revealed a de novo residual left-to-right shunt through the correctly implanted device. Three-dimensional transesophageal echocardiography (3D TEE) further clarified this finding by showing a perforation of the device membrane coating. The patient underwent transcatheter closure of the residual shunt with a 20 mm Ultrasept PFO(®) device...

Transcatheter closure of the left atrial appendage (LAA) is increasingly considered as an alternative to oral anticoagulation in patients with previous major bleeding or at high-risk of bleeding. Device embolization with transcatheter LAA closure is a rare complication. Most cases are asymptomatic, but it can be life threatening. Depending on the location of embolization, percutaneous retrieval is feasible. Snares are usually used for retrieval, but other devices may be used. We report the case of a 63-year gentleman who underwent an uneventful LAA closure with Watchman device and routine testing next day showed embolization to the abdominal aorta...
