Improvement on Left Ventricular Function Assessed by Speckle Tracking Echocardiography after Aortic Valve Replacement for Severe Aortic Stenosis

Abstract Background: Calcification of a congenitally existing bicuspid or trileaflet valve is a common cause of aortic stenosis; rheumatic illness also plays a role. Left ventricular heart failure in particular has been linked to an elevated mortality risk in patients with severe AS, and this dysfunction remains over time. Serious problems and even mortality might occur when AS leads to LV failure. Aim of Study: Assess the value of 2D speckle tracking echocardiography in detection of LV improvement after AVR in patients with severe aortic stenosis. Patients and Methods: This research was conducted in Islamic Center of Cardiology, Al-Azhar University. From January 2020 to March 2022. The research included 40 patients suffer from severe aortic stenosis (AS). AVR was done in the Cardiothoracic Surgery units of the Faculty of Medicine, Al-Azhar University. Results: Except for LVEDV, there was no notable change in echocardiographic data after 1 week of AVR. There was a substantial change in echocardiographic data at baseline after 1 month, with the exception of LVEF and GCS. With the exception of LVEF, there was a significant change in echocar-diographic data at 3 months. Conclusion: Early recovery of LV longitudinal function is indicated by the improvement in GLS seen 3 months after AVR, despite the lack of a substantial change in LV ejection fraction.
