In this issue of the International Journal of Cardiovascular Sciences, Madeira et al. evaluated the influence of percutaneous left atrial appendage (LAA) occlusion device on left atrial (LA) function. They assessed several parameters of atrial function, including LA strain and strain rate by speckle-tracking echocardiography (STE) of 16 patients, 75% with permanent atrial fibrillation, undergoing percutaneous LAA closure. No differences were found in maximum and minimum LA volume or LA emptying fraction before and 3 months after the procedure. Similarly, […]

Abstract The term “Remora” (hindrance) – re (again)/mora (delay) -originally designated a family of fishes – the suckerfishes. In ancient Greece and Rome and up to the early 19th century, these fishes were believed to slow down ships by attaching to them. Medicine adopted the term “remora” to describe fluid/blood stasis. Intracardiac blood stasis, or remora, especially in the left atrial appendage, is associated with thrombogenesis and responsible for cardioembolic phenomena. The slow and swirling movement of blood causes the […]

Abstract Background: Percutaneous left atrial appendage (LAA) occlusion may be an alternative therapy for atrial fibrillation (AF) patients with contraindication for anti-coagulation therapy. However, the influence of LAA occlusion on left atrial (LA) performance has not been studied. Objective: Our aim was to evaluate the influence of percutaneous LAA occlusion device on LA function by transthoracic echocardiography plus speckle-tracking echocardiography (STE). Methods: We included 16 patients undergoing percutaneous LAA closure with adequate echocardiographic window for the study of LA mechanics. […]
