Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Left atrial appendage closure with amplatzer cardiac plug in atrial fibrillation: initial European experience

, 2011
In most patients with atrial fibrillation (AF) and stroke, there is thrombotic embolization from the left atrial appendage (LAA). Percutaneous closure of the LAA is a novel alternative for the treatment of patients with AF at a high risk of stroke, in ...

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Arterial hypotension during percutaneous procedures in the left atrial: It is not always pericardial tamponade!

Heart Vessels and Transplantation, 2022
On the stage of left atrial percutaneous procedures a number of acute complications and their management have been described. In the current brief report, coronary air embolism, its acute manifestations, differential diagnosis and outcomes were presented

Impact of Preprocedural Computed Tomography on Left Atrial Appendage Closure Success [PDF]

, 2023
BACKGROUND The benefit related to the use of preprocedural computed tomography angiography (CCTA) on top of periprocedural echocardiography to plan percutaneous left atrial appendage closure (LAAC) procedures is still unclear.

Successful Percutaneous Retrieval of an Embolized MitraClip From the Right Subclavian Artery

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Single leaflet device attachment (SLDA) after mitral transcatheter valve edge‐to‐edge repair (M‐TEER) has been reported in up to 5% of patients. However, complete embolization of the M‐TEER device is exceedingly rare. Device retrievals in all previously reported cases were completed by vascular surgery cut down at the end. In this case, we are

Displacement of occluder after left atrial appendage closure: A case report

Clinical Case Reports
Key Clinical Message Atrial fibrillation is closely associated with thrombotic events. In non‐valvular atrial fibrillation, 90% of thrombi are formed by the left atrial appendage.

Percutaneous Left Atrial Appendage Occlusion: A View From the UK [PDF]

, 2020
AF is associated with an increased risk of thromboembolic events, which is usually managed with oral anticoagulation therapy. However, despite a broad range of anticoagulant options and improved uptake in anticoagulation over the past decade, there are ...

Percutaneous Left Atrial Appendage Closure Using a PFO Occluder After an Incomplete Surgical Ligation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The case regards a 73‐year‐old male who was referred for consideration of percutaneous left atrial appendage closure. His left atrial appendage was ligated during prior mitral valve surgery, but was noted to be patent on a recent transesophageal echocardiography. An Amulet device was selected based on CT planning.

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.
