Difference between cerebral embolic events following Transcatheter Aortic Valve Implantation (TAVI) and Surgical Aortic Valve Replacement (SAVR): a diffusion weighted MRI study
نویسندگان
چکیده
Background Transcatheter Aortic Valve Implantation (TAVI) is used to treat symptomatic severe aortic stenosis in a non-surgical high risk population. The incidence of stroke and micro-infarction is higher in the TAVI population compared to surgical aortic valve replacement (SAVR) at 30 days, which may be due to various factors such as valve calcification and aortic atheroma. However, the natural history and clinical consequences of micro-infarction is unknown.

Consequence of cerebral embolism after transcatheter aortic valve implantation compared with contemporary surgical aortic valve replacement: effect on health-related quality of life.
BACKGROUND Incidence of cerebral microinfarcts is higher after transcatheter aortic valve implantation (TAVI) compared with surgical aortic valve replacement (SAVR). It is unknown whether these lesions persist and what direct impact they have on health-related quality of life. The objective was to identify predictors of cerebral microinfarction and measure their effect on health-related quality...
متن کاملCognitive function after transapical aortic valve implantation: a single-centre study with 3-month follow-up.
OBJECTIVES Reports on adverse neurological events following transcatheter aortic valve implantation (TAVI) have focused on strokes, while more subtle postoperative cognitive decline has not yet been systematically investigated. In this study, we prospectively examined neurological and cognitive outcomes in patients undergoing transapical (TA) and surgical aortic valve replacement (AVR). METHO...
متن کاملTranscatheter Aortic Valve Implantation Compared With Surgical Aortic Valve Replacement in Low-Risk Patients.
BACKGROUND The proven efficacy of transcatheter aortic valve implantation (TAVI) in high-risk patients is leading to the expansion of its indications toward lower-risk patients. However, this shift is not supported by meaningful evidence of its benefit over surgical aortic valve replacement (SAVR). This analysis aims to describe outcomes of TAVI versus SAVR in low-risk patients. METHODS AND R...
متن کاملA CMR study assessing aortic valve hemodynamics post-transcatheter aortic valve implantation compared to surgical aortic valve replacement
Transcatheter aortic valve implantation (TAVI) removes the valvular impedance associated with aortic stenosis but can be complicated by significant aortic regurgitation. Using cardiovascular magnetic resonance we assessed the change in trans-aortic pressure gradient and regurgitant fraction 6 months post-TAVI and compared this to a surgical aortic valve replacement (SAVR) cohort. TAVI was super...
متن کاملA 3-center comparison of 1-year mortality outcomes between transcatheter aortic valve implantation and surgical aortic valve replacement on the basis of propensity score matching among intermediate-risk surgical patients.
OBJECTIVES This study sought to compare all-cause mortality in patients at intermediate surgical risk undergoing transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR). BACKGROUND Physicians are selecting "lower" surgical risk patients to undergo TAVI. No clinical data exist about the clinical outcomes of TAVI versus SAVR among intermediate-surgical-risk pa...
