Abstract In some transcatheter aortic valve implantation (TAVI) procedures, difficulty in crossing the valve delivery system occurs. There are some described anatomical risk factors as extreme angulation, heavy calcification, and bicuspid morphology. A possible reason may be an unfavorable angle of approach because of the outward push by the incoming crimped bioprosthesis and insufficient support/trackability of the extra stiff wire. Several techniques, tips, and tricks have been developed to overcome this problem and avoid procedure failures, such as the “pull-and-push” […]

Sex is an important biological variable in the pathophysiology of cardiovascular disease. , In fact, it could determine great differences in manifestation, treatment, and outcomes of several heart disorders. At the level of the aortic valve, there are sex-specific factors related to the pathogenesis of aortic stenosis (AS) that influence hemodynamics changes resulting from pressure overload response, and they should be considered in the management of patients. Despite the fact that sex-based differences in AS exist, they are often not […]

Abstract Degenerative aortic stenosis is currently a public health problem. Affecting the elderly population, this pathology has been showing an increasing prevalence as a direct result of the population aging. In this context, women have a greater life expectancy, corresponding to most of the population with degenerative aortic stenosis. Specific characteristics of this pathology in females are present in the diagnosis, pathophysiology, anatomical aspects, imaging and in therapeutic approach. Women present a more severe disease with less valve calcification than […]

Introduction Aortic valve replacement (AVR) is an established treatment modality in patients with severe symptomatic aortic stenosis (AS)., Given the increased mortality and morbidity of AVR for the high-risk patients and the poor long-term results of balloon aortic valvuloplasty, transcatheter aortic valve implantation (TAVI) is increasingly accepted treatment option who are not candidates for AVR. We describe here a case of succesfully implanted Edwards SAPIEN XT transcatheter heart valve without aortography guidance due to multiple arterial access problems and complicated […]
