Untreated ventricular septal defect (VSD) is an important cause of congestive heart failure in early infancy. Growth is impaired in this population, and surgical closure is challenging because of congestion in the lungs, making infants prone to respiratory infection, and because of their poor nutritional status. The aim of this study is to share our experience with percutaneous VSD closure in patients under 1 year of age. Patients with hemodynamically significant left-to-right shunt, less than 1 year of age, and with VSD diameter ≤ 6 mm were retrospectively included in the study between December 2014 and January 2017...

Since the first percutaneous left atrial appendage occlusion (LAAO), many studies have shown the safety and efficacy of this technique to prevent embolic strokes in nonvavular atrial fibrillation. The design, characteristics, and clinical data of the most frequently used devices for LAAO are reviewed, including the Amplatzer cardiac plug and Amulet (Abbott Vascular), the Watchman (Boston Scientific), and the LARIAT device (SentreHEART). Similarly, newer closer devices, such as Ultraseal (Cardia), LAmbre (Lifetech), and Coherex WaveCrest (Johnson & Johnson), are also discussed...

Percutaneous left atrial appendage occlusion (LAAO) for stroke prevention in patients with atrial fibrillation has significantly advanced in the past 2 decades. LAAO has emerged as a feasible and safe alternative to oral anticoagulants in patients who are deemed high risk for bleeding or are ineligible to receive anticoagulation. Herein, the authors review the main design features of the AMPLATZER Amulet device and describe step-by-step technical considerations for implantation of this LAAO device.

AMPLATZER devices preceded WATCHMAN occluder in 2002 for catheter-based left atrial appendage occlusion. The AMPLATZER technique facilitates simultaneous closure of atrial shunts using two devices through one gear. Randomized WATCHMAN follow-up data showed a mortality benefit over warfarin. AMPLATZER data make this likely valid for the strategy. Particularly young people with atrial fibrillation should be offered left atrial appendage occlusion because the risk is confined to the intervention and early postintervention period...

An 18-month-old male Akita Inu dog developed fever and lameness 8 months after successful transcatheter closure of a patent ductus arteriosus with an Amplatz Canine Duct Occluder (ACDO). Corynebacterium species were cultured from 3 blood samples. Echocardiography showed a vegetative process on the aortic valves. The dog died spontaneously 3 days after development of the initial signs. Necropsy confirmed the presence of bacterial ductal arteritis and myocarditis, and revealed an incomplete endothelialization of the intraductal metal implant...

It has been over a decade since dedicated Amplatzer devices have been used for left atrial appendage occlusion (LAAO) in patients with atrial fibrillation. The first was the Amplatzer Cardiac Plug (ACP) that is now replaced in most countries by the Amplatzer Amulet device. Most of the clinical data for ACP come from the ACP multicenter registry that included 1047 patients from 22 sites, whereas the largest to date report on the Amplatzer Amulet is a recently published prospective multicenter study in 1088 patients from 64 sites...

In this report, we provided details of periprocedural echocardiographic guidance for patients undergoing Amplatzer-Amulet device left atrial closure. Familiarity with left atrial appendage (LAA) occlusion devices and the required left atrial examination and measurements are key before device placement. Device placement is assisted by transesophageal echocardiography (TEE) and fluoroscopy, but TEE will be the main guide for patients with renal insufficiency in whom contrast dye use needs to be minimal. TEE is also used to confirm LAA occlusion with the device and finally detect complications throughout the procedure and into the postoperative period...

We present the case of a 54-year-old male patient diagnosed with a right upper lobe lung cancer and was referred for resection. Positron emission tomography-computed tomography scan showed a prominent vascular structure in the right lung, suspicious for vascular malformation. A computed tomography angiography was done, demonstrating an intercostobronchial trunk-pulmonary artery fistula. There was also non-tapering dilated wandering pulmonary artery coursing through the right lower lung without any abnormal connection with pulmonary veins and were supplying normal lung parenchyma...

Device therapy is a viable alternative to open heart surgery in the management of intracardiac defects. The Amplatzer septal occluder (ASO) is one such device that has been adapted to close a wide variety of cardiac defects with few complications and a high success rate. This is a retrospective review of all the patients who received the ASO between 2012 and 2016 at the University of Kentucky. In total, 169 patients underwent percutaneous closure of a septal defect with Amplatzer during the timeframe studied, and of those, 91% received the device for an atrial septal defect or patent foramen ovale...

BACKGROUND: Device-related thrombus (DRT) after left atrial appendage occlusion is a worrisome finding with little knowledge about when to expect it and how to prevent it. This study sought to investigate correlates of DRT after left atrial appendage occlusion, its time of diagnosis, and particularly, association with postimplantation dual antiplatelet therapy duration. METHODS AND RESULTS: Consecutive patients (n=102) after left atrial appendage occlusion with AMPLATZER Cardiac Plug/Amulet (n=59) or WATCHMAN (n=43) were included in a prospective registry (October 2011-May 2016)...

OBJECTIVE: Percutaneous closure of patent foramen ovale (PFO) and atrial septal defect (ASD) is routinely performed under general anesthesia or deep sedation and use of transesophageal (TEE) or intracardiac echocardiography, incurring longer duration and higher cost. We have used a simplified, economical, fluoroscopy-only guided approach with local anesthesia, and herein report our data. METHODS: The study includes 112 procedures in 110 patients with PFO (n=75) or ASD (n=35), with use of an Amplatzer occluder, heparin and prophylactic antibiotics...

Atrial fibrillation is commonly coexistent with heart failure, and the management of the heart failure patient would be incomplete without an appreciation for atrial fibrillation management. There are many complications associated with oral anticoagulation in the prevention of stroke related to atrial fibrillation. In recent years, the advent of several percutaneous left atrial appendage (LAA) occlusion/closure strategies has sought to provide an alternative treatment modality. Here, we systematically review the published literature to investigate the efficacy and safety of percutaneous LAA occlusion/closure devices...

Transcatheter closure of arterial duct (AD) remains challenging in low-weight patients and using Amplatzer Duct Occluder devices is still considered off-label in infants < 6 kg. This study aimed to report a large, single-center experience of percutaneous AD closure in infants < 6 kg as well as to compare the most frequently used devices, Amplatzer Duct Occluder type I (ADO I) and Amplatzer Duct Occluder type II Additional Sizes devices (ADO II-AS) (St. Jude Medical Corp, St. Paul, MN, USA). From March 2000 to March 2017, among the 762 patients submitted to percutaneous closure of AD at our Institution, 33 were infants < 6 kg (age 4...

A 5-month-old infant, referred to our institution for percutaneous arterial duct (AD) embolization, showed multiple huge pulmonary arteriovenous malformations (PAVMs) associated with a small AD and several tiny systemic-to-pulmonary collaterals. This anatomic arrangement was a possible cause of lack of cyanosis and disproportionately higher hemodynamic relevance of the ductal shunt. The PAVMs became pathophysiologically evident immediately after the closure of AD and systemic to pulmonary artery collaterals and presented clinically with a life-threatening cyanosis...

Sinus of Valsalva (SV) rupture is a rare, cardiac complication after surgical repair of complex congenital heart disease. This paper reports a 4-year-old male child with double outlet right ventricle (RV) and pulmonary stenosis with superior-inferior arrangement of the ventricles, who was submitted to surgical repair using the "reparation a l'etage ventriculaire" procedure. A few months after an uneventful surgical repair, his clinical condition abruptly worsened because of the rupture of the right SV into the RV outflow tract resulting in large left-to-right shunt and RV functional impairment...
