Assessment of Left Ventricular Function in Patient with Atrial Fibrillation Uses Real-Time Triplain Speckle Tracking Incomparison with 2D Speckle Tracking.

Abstract

Background: The Yellow Emperor's Classic of Internal Medicine by Huang Ti NeiChing SuWen contains the earliest historical account of what could be atrial fibrillation (AF), dating back some 4000 years. AF is now considered to be the most common arrhythmia of clinical significance.

Aim: This paper focused on the assessment of left ventricular systolic function using (triplane speckle tracking strain) and compare with two-dimensional speckle tracking to identify its role as a predictor of subclinical left ventricular systolic dysfunction in AF patients with normal ejection fraction.

Patients and methods: Our study was interested to study patients with normal ejection fraction by assessing left ventricular systolic function by sing (triplane speckle tracking strain) as well as compare with two-dimensional speckle tracking to identify its role as a predictor of subclinical left ventricular systolic dysfunction in AF. Our study was based on databases collected from hospitals in Baghdad-Iraq between 16th July 2021 and 18th September 2022.  The paper also used quantitative data, including percentages, means, standard deviations, and ranges, to analyze various variables.

Results and discussion: As many of our patients have atrial fibrillation, we expect the presence of subtle LV systolic dysfunction despite a normal left ventricular ejection fraction (LV EF). This condition is known as heart failure with preserved left ventricular ejection fraction (HFPEF). In addition, GLS in AF patients was significantly influenced by LVEF, E, and E'. AF involves a reduction in atrial mechanical contraction, resulting in impaired LV filling, which can adversely affect haemodynamic performance and cause LV systolic dysfunction.

Conclusion: Triplane echocardiography allows for the assessment of LV GLS in a single beat, making Real-Time triplane a simple tool to use for AF patients. Triplane echocardiography allows for the assessment of LV GLS in a single beat, making Real-Time triplane a simple tool to use for AF patients. In addition, this study presents evidence that GLS is more impaired in AF patients than in those without AF.
