Abstract: Low-flow, low-gradient (LF/LG) aortic stenosis (AS) is a diagnostic dilemma [(1)][1] as routine work-up remains challenging. Dobutamine stress echocardiography (DSE) and multidetector computed tomography (MDCT) represent accepted imaging modalities for further subcategorization into a true… read more here.

Abstract: Objectives We hypothesised that low flow low gradient aortic stenosis (LFLGAS) is associated with more severe coronary microvascular dysfunction (CMD) compared with normal-flow high-gradient aortic stenosis (NFHGAS) and that CMD is related to reduced cardiac… read more here.

DOI: 10.5152/anatoljcardiol.2022.1981
Abstract: Subaortic membrane (SM) is a relatively rare congenital heart disease in adulthood mostly detected in pediatric patients.1 In this study, we report a case who underwent redo surgery due to a high-gradient prosthetic aortic valve… read more here.
