MATERIALS AND METHODS: A comprehensive literature search was conducted using PubMed, CINAHL, and Scopus databases, adhering to PRISMA guidelines. Fifteen studies encompassing 240 patients treated with embolization (using coils or Amplatzer Vascular Plugs (AVP)) were analyzed...

BACKGROUND: Clinical practice guidelines recommend oral anticoagulation (OAC) for stroke prevention in selected patients with atrial fibrillation (AF). However, some patients still experience thrombo-embolic events despite adequate anticoagulation. The optimal management of these cases remains uncertain, leading to practice pattern variability. We present a series of three cases illustrating the use of left atrial appendage occlusion (LAAO) as an adjunctive stroke prevention strategy in AF patients with recurrent thrombo-embolic events despite adequate anticoagulation...

BACKGROUND: Percutaneous closure of aortic-to-right ventricle (ARV) fistula has emerged as an alternative to surgical management in selected cases. The use of three-dimensional (3D) printing in interventional planning for structural heart disease provides a concrete understanding, and it is useful in diagnostic assessment and to guide treatment approaches and to simulate procedures. CASE SUMMARY: We report a case of a 70-year-old male presenting in cardiogenic shock due to severe aortic stenosis and reduced left ventricular ejection fraction...

The aim of this study was to introduce an interventional heart catheterization to close patent ductus arteriosus (PDA), ventricular septal defect (VSD), atrial septal defect (ASD), and pulmonary hypertension without complications from open heart surgery and a 3-day hospitalization period. PDA, VSD, and ASD are among the most common abnormalities associated with various complications. This case is a 3.5-year-old girl with frequent lung infections and Failure to thrive. Treatment in the first stage aims to close the PDA using Amplatzer ADO II type AGA, size 5-6 mm and ASD using Amplatzer Septal Occluder size 15 mm...

BACKGROUND Congenital heart diseases (CHDs) are the most common form of birth defects, affecting the structure and function of neonatal hearts. Pulmonary valve stenosis (PVS) and ventricular septal defects (VSD) are 2 of the more prevalent forms, both of which can lead to significant morbidity if left untreated. The emergence of transcatheter techniques has revolutionized the therapeutic landscape, presenting minimally invasive yet effective alternatives to open-heart surgery and significantly reducing associated patient morbidity and recovery time...

BACKGROUND AND OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is the recommended treatment for large or complex renal stones. This study aims to evaluate the outcomes of mini PCNL in obese and nonobese patients and to compare the outcomes of mini and standard PCNL in the obese population. METHODS: We retrospectively reviewed our PCNL database to identify patients who had undergone mini (Amplatz sheath size 17.5Ch) or standard (Amplatz sheath size ≥26Ch) PCNL between 2005 and 2022...

BACKGROUND: Left atrial appendage (LAA) closure is an alternative to chronic anticoagulation for stroke prevention in patients with nonvalvular atrial fibrillation. Multiple devices were used for LAA closure, with the Amplatzer Amulet LAA Occluder (Abbott, Chicago, IL, USA) and Watchman device (Boston Scientific, Marlborough, MA, USA) being the most commonly used in clinical practice. In August 2021, the FDA approved the use of the Amplatzer Amulet LAA Occluder. There is still a knowledge gap in the safety profile of the Amplatzer Amulet LAA Occluder device in comparison to the Watchman device...

BACKGROUND: The Woven EndoBridge (WEB) device (MicroVention, Tustin, CA, USA) has an excellent safety profile. While major complications such as device malposition and migration are rare, they can have serious consequences if not addressed promptly. Our case series describes the safety and efficacy of Amplatz goose neck microsnare device (Medtronic in Irvine, CA, USA) in endovascular retrieval of a detached WEB device. METHODS: We retrospectively reviewed six consecutive patients who underwent endovascular WEB retrieval using Amplatz microsnare device between March 2012 and December 2022...

Penetrating cardiac trauma is a fatal condition and can result in the injury of various parts of the heart. Ventricular Septal Defect (VSD) following these traumas occurs only in 1-5% of cases. The patients' conditions depend on location, size, and concomitant injuries. One of the uncommon coincidences with the VSD is Mitral Regurgitation (MR) due to injury to sub-valvular structures. In this study, we report a case of concomitant traumatic-induced VSD and MR in a 14-year-old boy following a stab wound to his chest...

Left atrium appendage closure is a safe and effective therapy for patients with atrial fibrillation and high thromboembolic and hemorrhagic risks. Prosthesis embolization is a potential major complication with an incidence of 0.07%. We report a case of migration of an Amplatzer Amulet (Abbott) device that was successfully retrieved in an innovative way (4).

BACKGROUND: Approximately 90% of intracardial thrombi originate from the left atrial appendage in non-valvular atrial fibrillation patients. Even with anticoagulant therapy, left atrial appendage thrombus (LAAT) still occurs in 8% of patients. While left atrial appendage closure (LAAC) could be a promising alternative, the current consensus considers LAAT a contraindication to LAAC. However, the feasibility and safety of LAAC in patients with LAAT have yet to be determined. METHODS: This systematic review synthesizes published data to explore the feasibility and safety of LAAC for patients with LAAT...

Transcatheter closure of muscular ventricular septal defects (VSD) remains a safe and effective method with low complication rates. However, device migration can pose a significant challenge to interventional cardiologists due to potential mortal consequences. A 21-year-old female presented to our clinic with exertional dyspnea and was diagnosed with a muscular VSD. The defect was percutaneously closed using an Amplatzer occluder device. On the first post-procedural day, the patient experienced repeated episodes of coughing and mild hemoptysis...

BACKGROUND: The optimal antithrombotic therapy following left atrial appendage occlusion (LAAO) remains debated. Ideally, this therapy should effectively prevent device-related thrombosis (DRT) while minimising the associated bleeding risk. AIMS: We aimed to evaluate the long-term safety and efficacy of a postprocedural single antiplatelet therapy (SAPT) strategy following Amplatzer LAAO in a large consecutive cohort. METHODS: This retrospective, single-centre, observational study included all patients discharged on SAPT after LAAO with the Amplatzer Cardiac Plug (ACP) or Amplatzer Amulet between March 2010 and December 2021 at Aarhus University Hospital, Denmark...

Ventricular septal defect (VSD) is a rare congenital heart disease in dogs. Hemodynamically important interventricular defects must be closed to improve the prognosis. This case report describes successful interventional transcatheter closure of a muscular VSD in a young Maltese and poodle mixed-breed dog with a large muscular interventricular defect (~5 mm in diameter) with a high rate of left-to-right shunt flow. The VSD was closed with a customized Amplatzer-type VSD occluder via a percutaneous transvenous (jugular) approach...

OBJECTIVES: Percutaneous closure of a patent foramen ovale (PFO) for the prevention of recurrent paradoxical thromboembolic events has been shown to be safe and effective in randomized controlled trials. However, it remains uncertain if differences in the structure and design of the occluder devices impact the outcomes. The aim of this study was to compare results of percutaneous PFO closure using 2 widely used double-disc occluders. METHODS: Consecutive patients who underwent percutaneous PFO closure with the Abbott Amplatzer occluder (APO) or the Occlutech Figulla-Flex-II occluder (OPO) at the Heart Center Lucerne between February 2017 and December 2022 were included in a registry...

AIMS: Two randomized clinical trials, REDUCE and RESPECT, demonstrated that patent foramen ovale (PFO) closure in combination with antithrombotic therapy was more effective for the prevention of recurrent ischemic stroke compared with antithrombotic therapy alone. The aim of this study was to determine the relative efficacy and safety of the PFO closure devices used in REDUCE (HELEX and CARDIOFORM Septal Occluders) compared with the device used in RESPECT (Amplatzer PFO Occluder). METHODS: An unanchored matching-adjusted indirect comparison (MAIC) of the PFO closure arms of the REDUCE and RESPECT trials was performed using patient-level data from REDUCE weighted to match baseline characteristics from RESPECT...

INTRODUCTION: In patients with non-valvular atrial fibrillation (NVAF), mechanical occlusion of the left atrial appendage (LAA) using a permanently implanted device may be an effective alternative to oral anti-coagulants (OAC). To facilitate left atrial appendage closure (LAAC), multiple percutaneous devices have been proposed. Watchman Generation 2.5 and Amplatzer Amulet are the two most popular used devices for preventing stroke in patients with NVAF. We sought to compare safety and efficacy outcomes between Watchman 2...
