Abstract

The aim of this study was to evaluate the efficiency of left atrial strain (S) and strain rate (SR) imaging in assessing left atrial appendage (LAA) function. We studied 78 consecutive patients (35 females and 43 males; mean age 38 ± 15 years) referred for transesophageal echocardiography (TEE). LAA late emptying velocity (LAA-EV) was calculated. Real-time color Doppler myocardial velocity imaging (MVI) data were recorded from the LAA by TEE and the lateral wall of the left atrium (LA) by transthoracic echocardiography. Longitudinal S and SR were measured in the mid portion of the lateral LA wall and lateral LAA wall during the contractile period. LAA late systolic velocity (LSV) and LA-LSV were obtained from Doppler analysis. A significant positive correlation was detected between LAA-EV and MVI parameters (for LAA-S, r = 0.88, p < 0.001; for LAA-SR, r = 0.84, p < 0.001; for LAA-LSV, r = 0.83, p < 0.001; for LA-S, r = 0.84, p < 0.001; for LA-SR, r = 0.79, p < 0.001, and for LA-LSV, r = 0.70, p < 0.001). In addition, a significant positive correlation was detected between LAA-S and LA-S (r = 0.85, p < 0.001). We suggest that LA-S and LA-SR imaging is a beneficial method to evaluate LAA functions noninvasively.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
