History of major gastrointestinal (GI) bleeding may represent a frequent clinical indication for left atrial appendage occlusion (LAAO) in patients with non-valvular atrial fibrillation (AF). This study aims to investigate the procedural safety and long-term outcome of patients with previous major GI bleeding (MGIB) who underwent LAAO. Data from the Amplatzer Cardiac Plug multicenter registry on 1,047 patients were analyzed. Patients with previous MGIB as indication for LAAO were compared with patients without previous MGIB...

Patients who present with both severe mitral and tricuspid regurgitation who are symptomatic despite optimal medical therapy and at prohibitive risk for surgery pose a significant therapeutic challenge. The MitraClip device (Abbott Vascular) is approved for percutaneous mitral valve repair in high-risk and non-operative patients, and has also been used for tricuspid valve repair. Imaging support for percutaneous edge-to-edge tricuspid valve repair has not been reported and is a vital part of the procedure. Here, we present a periprocedural imaging strategy for percutaneous tricuspid valve repair with the MitraClip device using a bicuspidization technique...

BACKGROUND: In patients with non-valvular atrial fibrillation (NVAF), intracranial bleeding (ICB) constitutes a very challenging situation in which the rate of both ischemic and hemorrhagic events is increased. In these patients, left atrial appendage occlusion (LAAO) might represent a very valid alternative. OBJECTIVES: To investigate the procedural safety and long-term outcome of patients undergoing LAAO therapy due to previous ICB. METHODS: Data from the Amplatzer Cardiac Plug multicenter registry on 1047 consecutive patients were analyzed...

OBJECTIVES: This study aimed to provide a systematic review of device-associated thrombosis (DAT) after left atrial appendage occlusion (LAAO) with the Watchman, Amplatzer Cardiac Plug, and Amulet devices. BACKGROUND: DAT is known as a complication of LAAO but data about its clinical impact is scarce. METHODS: A systematic review of studies evaluating the incidence, treatment and clinical implications of DAT from January 2008 to September 2015 was conducted...

Cardioembolic strokes are generally more lethal and disabling than other source of strokes. Data from PROTECT AF (Watchman Left Atrial Appendage Closure Technology for Embolic Protection in Patients With Atrial Fibrillation) suggest that strokes after left atrial appendage occlusion (LAAO) with the Watchman device are less disabling than those in the warfarin group. No data assessing the severity of strokes after LAAO with the AMPLATZER Cardiac Plug (ACP) are available. The objective of the study was to evaluate the severity of cerebrovascular events after LAAO with the ACP in a population mostly characterized by an absolute or relative contraindication to oral anticoagulation...

The increasing interest in left atrial appendage occlusion (LAAO) for ischaemic stroke prevention in atrial fibrillation (AF) fuels the need for more clinical data on the safety and effectiveness of this therapy. Besides an assessment of the effectiveness of the therapy in specific patients groups, comparisons with pharmacological stroke prophylaxis, surgical approaches, and other device-based therapies are warranted. This paper documents the consensus reached among clinical experts in relevant disciplines from Europe and North America, European cardiology professional societies, and representatives from the medical device industry regarding definitions for parameters and endpoints to be assessed in clinical studies...

BACKGROUND: This is the first clinical report on experience in the use of the Gore embolic filter in carotid interventions. It was designed as a guidewire and embolic protection system in carotid, peripheral, and coronary interventions. The ability to capture debris is driven by the frame of the filter, which is designed to improve vessel wall apposition and allows a short landing zone. METHODS: We report the results of the first 20 consecutive patients undergoing carotid artery stenting using the Gore embolic filter in our institution...

Transcatheter therapies for the treatment of valve heart diseases have expanded dramatically over the last years. The new developments and improvements in devices and techniques, along with the increasing expertise of operators, have turned the catheter-based approaches for valvular disease into an established treatment option. Various imaging techniques are used during these procedures, but echocardiography plays an essential role during patient selection, intra-procedural monitoring, and post-procedure follow-up...

AIMS: Gender has been an important factor in outcomes after mitral valve surgery; however, its effect on percutaneous mitral valve repair is not well known. We aimed to report the effect of gender on outcomes in a large European prospective, multicentre, non-randomised post-approval study of percutaneous mitral valve repair. METHODS AND RESULTS: Two hundred and five female and 362 male patients with significant mitral regurgitation underwent percutaneous repair at 14 European sites from October 2008 to April 2011...

Ischemic stroke following acute myocardial infarction (AMI) is a rare but serious complication due to left ventricular thrombus formation and atrial fibrillation. Early revascularization of the culprit coronary lesion is essential. Treatment trends may affect the risk. Conversely, the greater use of antiplatelet agents to reduce the risk of ischemic stroke could increase the risk of hemorrhagic stroke. The risk of stroke after AMI has decreased significantly with more use of percutaneous coronary intervention and antithrombotic therapies in the acute setting, and statins, antihypertensive medications, and dual antiplatelet therapy as secondary prevention strategies...

BACKGROUND: The purpose of the study was to determine the efficacy and safety of left atrial appendage (LAA) closure with a micropuncture pericardial access approach and the new LARIAT(+) suture delivery device. METHODS: Seventy-two patients with atrial fibrillation were enrolled to undergo telescopic micropuncture pericardial access and percutaneous ligation of the LAA with the LARIAT(+) device. LAA closure was confirmed with transesophageal echocardiography (TEE) and contrast fluoroscopy immediately, then with TEE at 30days and 90days post-LAA ligation...

METHODS AND RESULTS: Physicians who are experts in LAAO and had personal clinical experience with the AMPLATZER Amulet device were asked to contribute in the preparation of this consensus document. Twenty-seven physicians (20 interventional cardiologists and 7 electrophysiologists) from 14 different countries reviewed the manuscript...

As the global burden of cardiovascular disease continues to increase worldwide, nurturing the development of early-career cardiologists interested in global health is essential to create a cadre of providers with the skill set to prevent and treat cardiovascular diseases in international settings. As such, interest in global health has increased among cardiology trainees and early-career cardiologists over the past decade. International clinical and research experiences abroad present an additional opportunity for growth and development beyond traditional cardiovascular training...
