BACKGROUND Reversibility of left ventricular (LV) dysfunction in high-risk aortic stenosis patient and its impact on survival after transcatheter aortic valve replacement (TAVR) are unclear. We aimed to evaluate longitudinal changes of LV structure and function after TAVR and their impact on survival. METHODS AND RESULTS We studied 209 patients with aortic stenosis who underwent TAVR from May...
AIMS Longitudinal strain determined by speckle tracking is a sensitive parameter to detect systolic left ventricular dysfunction. In this study, we assessed regional and global longitudinal strain values in long-term heart transplants and compared deformation indices with ejection fraction as determined by transthoracic echocardiography (TTE) and multislice computed tomographic coronary angiogr...
AIMS To examine left ventricular (LV) longitudinal systolic myocardial function in patients with hypertrophic obstructive cardiomyopathy (HOCM) before and after transcoronary ablation of septal hypertrophy (TASH). METHODS AND RESULTS Twenty-three of 39 consecutive patients with HOCM had serial two-dimensional (2D) echocardiograms available for speckle tracking analyses before and up to 36 mon...
OBJECTIVE The aim of this study is to compare the impact of two different loading conditions on myocardial contractility in asymptomatic patients with normal EF by using stain rate imaging (SRI). METHODS A total of 27 patients with severe aortic regurgitation (mean age 50 ± 11 years) and 25 patients with severe aortic stenosis (mean age 53 ± 15 years) were prospectively recruited. Fifteen hea...
Abstract Funding Acknowledgements Type of funding sources: None. Introduction/purpose Cirrhotic cardiomyopathy is characterized by high cardiac output, reduced peripheral resistance and diastolic dysfunction has been correlated with cirrhosis severity prognosis. Global longitudinal strain (GLS) a sensitive marker which considered relatively independent preload afterload conditions thus may be d...
