Multiparametric Assessment of Post-Transcatheter Aortic Valve Replacement Paravalvular Regurgitation Grading by Transthoracic Echocardiography and Cardiac Magnetic Resonance
نویسندگان
چکیده
Purpose: Paravalvular regurgitation post-transcatheter valve replacement is associated with poor outcomes. The Valve Academic Research Consortium has defined qualitative and quantitative criteria for assessing paravalvular leak severity by transthoracic echocardiography. Cardiac magnetic resonance imaging is highly accurate and reproducible in measuring aortic flow volumes, and has been used for further evaluation of paravalvular regurgitation. The agreement between the multiparametric grading of paravalvular regurgitation by transthoracic echocardiography and cardiac magnetic resonance imaging is unclear.

Quantitative analysis of post-TAVI aortic regurgitation with cardiovascular magnetic resonance and the relationship to transthoracic echocardiography
Background Transcatheter Aortic Valve Implantation (TAVI) is increasingly used to treat patients with severe aortic stenosis at high surgical risk. The severity of post-implantation valvular or paravalvular regurgitation has been shown to adversely affect patient outcome. The aim of the study was to assess the prevalence and severity of aortic regurgitation (AR) at 6 months post-TAVI using card...

Background The most common complication of Transcathether Aortic Valve Replacement (TAVR) is aortic regurgitation (AR). Typically, this regurgitation is in the mild range, yet in a smaller subset AR could be in the moderate-severe range. Significant regurgitation is usually due to paravalvular leak due to undersizing of the valve or malposition inferiorly into the left ventricular outflow tract...

Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...
متن کاملAortic insufficiency following transcatheter aortic valve replacement is underestimated by echocardiography compared with cardiac MRI
Background The degree of aortic insufficiency (AI) after transcatheter aortic valve replacement (TAVR) has been identified as a predictor of increased mortality. Since even mild AI is associated with increased mortality in some studies, accurate quantification of post-TAVR AI is critical. Assessment of AI by echocardiography is typically performed by visual inspection and semi-quantitative meth...
متن کاملQuantitative assessment of paravalvular regurgitation following transcatheter aortic valve replacement
Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement is a known complication associated with poorer outcomes. This article discusses the current techniques for assessing the severity of PVR, including angiography, hemodynamics, MRI, and echocardiography. The strengths and pitfalls of each modality are reviewed.
