Left atrial spontaneous echo contrast in patients with permanent pacemakers.
OBJECTIVE To determine the relations between left atrial appendage function, spontaneous echo contrast, and thromboembolism in patients with different modes of permanent pacemakers. PATIENTS AND METHODS 88 patients with pacemaker implantation and 25 healthy controls in sinus rhythm had transoesophageal echocardiographic examination of the left atrial appendage. Left atrial size, appendage are...
متن کاملInterobserver variability in the detection of spontaneous echo contrast, left atrial thrombi, and left atrial appendage thrombi by transoesophageal echocardiography.
OBJECTIVE To assess the interobserver variability between two observers from different echocardiographic laboratories. DESIGN Two observers reviewed video recordings blinded to the other's diagnosis. In part I (n = 88), they determined interobserver variability for spontaneous echo contrast, left atrial thrombi, and appendage thrombi. No diagnostic criteria for thrombi were defined. In part I...
متن کاملPoor Outcome of Stroke Patients With Atrial Fibrillation in the Presence of Coexisting Spontaneous Echo Contrast.
BACKGROUND AND PURPOSE Spontaneous echo contrast (SEC) is frequently detected in patients with atrial fibrillation (AF). Coexisting SEC in patients with AF may be associated with heightened thrombogenicity, which affects stroke outcomes. METHODS Consecutive stroke patients with nonvalvular AF who underwent transesophageal echocardiography were included in this study. We compared initial strok...
متن کاملSpontaneous echo contrast caused by platelet and leukocyte aggregates?
BACKGROUND AND PURPOSE Spontaneous echocardiographic contrast (SEC) is correlated to clinical thromboembolic events. We sought to determine the origin of SEC by utilizing direct analysis of left atrial blood. METHODS We examined the blood of 13 patients with and 19 without SEC. Blood samples were taken from the femoral vein and artery and from the right and left atria after transseptal punctu...
متن کاملClinical and echocardiographic characteristics of left atrial spontaneous echo contrast in sinus rhythm.
OBJECTIVES In this study we attempt to define the clinical and echocardiographic characteristics of patients with left atrial spontaneous echo contrast (LASEC) in sinus rhythm (NSR). BACKGROUND Left atrial spontaneous echo contrast in atrial fibrillation (AF) is associated with increased risk of thromboembolism. Little is known about its significance in NSR. METHODS We reviewed reports of 1...
