“…Our results were in line with many studies that investigated the effect of TAVI on ejection fraction post-procedure. Lwin et al [2] had 40 patients with significant aortic valve stenosis planned for transcatheter aortic valve implantation. World Journal of Cardiovascular Diseases was 78.6 ± 7.4 years.…”

“…Due to the prevalence of severe symptomatic AS in the geriatric population, AS presents usually with many co-morbidities, like hypertension, diabetes mellitus, and chronic kidney disease, which consequently increases the risk of cardiac surgery [1]. Transcatheter aortic valve implantation (TAVI) has established its effectiveness as a substitute to conventional surgery in patients with high grade aortic valve stenosis who have high cardiovascular surgery risk score [2]. TAVI can be performed using either self-expandable or balloon-expandable valved stents which would replace damaged and non-functioning aortic valves [3].…”

Background: Long standing aortic stenosis leads to elevated left ventricular (LV) pressure and as a result LV hypertrophy and myocardial fibrosis shall increase. The left ventricular ejection fraction (EF) usually remains adequately-preserved until advanced and late stages of aortic stenosis. But the preserved muscle of the LV is only limited to a portion of the entire myocardium. Speckle tracking echocardiography has proved its superiority to the standard two-dimensional echocardiography method in the detection of Left Ventricular (LV) function. Global Longitudinal strain (GLS) is considered as the most robust myocardial strain component. Objective: The aim of the study is to assess the early course of left ventricular reverse remodelling after Transcutaneous Aortic Valve Implantation (TAVI) in patients with symptomatic severe aortic valve stenosis. Methods: 50 patients with severe symptomatic valvular aortic stenosis undergoing TAVI as decided by the heart team after comprehensive discussion. Standard transthoracic echocardiography including Doppler analysis was performed. 2D speckle-tracking strain assessment of Global radial, circumferential and longitudinal strain at parasternal mid-ventricular short-axis view (at the level of papillary muscle) and from the apical long-axis, two-chamber and four-chamber views with a frame rate between 40 and 80 frames per second. Tracing of endocardial borders was done. Patients with significant coronary artery disease were fully revascularized by percutaneous coronary intervention prior to the study and the procedure. Results: 23 (46%) patients were males, while 27 (54%) were females. The patients' stratification according to comorbidities/associated risk factors re
