Abstract
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, [...]
Highlights
This is among the first studies to examine the effect of this procedure on left atrial (LA) function, for which the authors should be congratulated
The LA function is difficult to be assessed in patients with atrial fibrillation, and an addition analysis of strain and strain rate can be of great help
The authors demonstrated that the left atrial appendage (LAA) implantation in patients with high embolic risk, expressed by a median CHA2DS2-VASc score of 5 and HAS-BLED score of 3, did not negatively affect their left atrial function
Summary
This is among the first studies to examine the effect of this procedure on LA function, for which the authors should be congratulated. The LA function is difficult to be assessed in patients with atrial fibrillation, and an addition analysis of strain and strain rate can be of great help. The use of ventricular strain has become the standard of practice in cardiology today.
