Atrial fibrillation (AF) is most common arrhythmia and its prevalence appears to be
increasing as the population ages. Echocardiography can play a key role in risk stratification …

Aims Clinical benefit from ablation for long-standing persistent atrial fibrillation has remained
unknown. We hypothesized that successful ablation of long-standing persistent atrial …

Objective To investigate quantitatively the morphology, anatomy and function of the left atrial
appendage (LAA) and its relation with adjacent structures. Materials and Methods A total of …

Doppler measurement of left atrial appendage (LAA) blood velocity during transesophageal
echocardiography has been proposed as a method of assessing LAA contractile function …

Background The atrial appendage is a predilection site for thrombus formation. Mast cells
(MC) are a rich source of mediators that may be involved in the regulation of thrombus …

Information regarding the relation of left atrial (LA) function to transmitral and pulmonary
venous (PV) flow is limited. Using transesophageal echocardiography, we analyzed this …

Atrial fibrillation (AF) is present in 1% to 2% of the general population, and its prevalence
has been predicted to increase more than fivefold within the next 40 years. 1, 2 Patients with …

OBJECTIVE: The cut-and-sew Cox–Maze procedure is the gold standard for surgical
treatment of atrial fibrillation, but it is associated with long-term impairment of left atrial …

Thrombogenesis in the left atrial appendage (LAA) has been related to the special
morphology of this cavity and to its size and degree of dysfunction. However, no study has …

The role of transesophageal echocardiography (TEE) in thromboembolic risk stratification in
atrial fibrillation (AF) has not been established. Left atrial appendage contractile dysfunction …
