Abstract Background Left ventricular (LV) hypertrophy is a known compensatory mechanism to pressure overload in aortic stenosis (AS) patients. However, by cardiac magnetic resonance (CMR) different patterns of LV adaptation are seen in this group of patients. Aim To describe the patterns …

Abstract Introduction Calcium score of the aortic valve (CaScAoV) is recommended as a supporting tool to assist in the grading of aortic stenosis (AS) severity when echocardiographic assessment is inconclusive. However, a significant proportion of patients have CaScAoV values within a “grey …

Abstract Background Myocardial fibrosis (MF) is a common finding and a potential adverse prognostic marker in several cardiac diseases, including in severe aortic stenosis (AS). While histological analysis obtained through endomyocardial biopsy remains the gold-standard for MF assessment, non-invasive cardiac imaging may …

Abstract Background In patients with severe aortic stenosis (AS), left ventricular (LV) remodeling is believed to be a compensatory adaptive process which should reverse after aortic valve intervention. However, this is not always the rule and remodeling persistence may negatively impact post-procedural …

Abstract Background Left ventricular (LV) remodeling in patients with severe aortic valve stenosis (AS) is a complex process that goes beyond hypertrophic response and may involve reparative/replacement fibrosis. Currently, cardiac magnetic resonance (CMR) is the gold-standard imaging technique for detecting focal myocardial …

Abstract Background Relative apical sparing (RAS) of left ventricular (LV) longitudinal strain (LS) is a red flag marker for the suspicion of amyloid cardiomyopathy. However, it has also been described in patients with severe aortic stenosis (AS). Aim To assess the prevalence …

Abstract Background Left ventricular (LV) hypertrophy is a common expected finding in aortic stenosis (AS) patients. Cardiac magnetic resonance (CMR) plays an important role as a non-invasive method for determining LV mass and volume, and to characterize the LV remodeling response in …

Abstract Background Left ventricular myocardial work (LVMW) is a novel method to evaluated left ventricular (LV) function using pressure-strain loops. It might correct global longitudinal strain (GLS) for afterload, being eventually useful to assess whether GLS reduction is due to reduced contractility …

Abstract Background and aim Long-term data on the durability of transcatheter heart valves is scarce. This is of particular interest as indications expand to younger and lower surgical risk patients. We sought to assess the incidence of long-term structural valve dysfunction (SVD) …

Abstract Background Right ventricular (RV) function in aortic stenosis (AS) has been largely neglected. Recently it was demonstrated that right ventricular impairment may be influenced by left ventricular (LV) function and afterload, well before overt pulmonary hypertension development. Aim To describe the …
