A CMR study assessing aortic valve hemodynamics post-transcatheter aortic valve implantation compared to surgical aortic valve replacement
نویسندگان
چکیده
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 superior at reducing aortic pressure gradient and equal to SAVR at reducing aortic regurgitation at 6 months.

Transcatheter Aortic Valve Replacement: A Review Article
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 کاملThe effect of myocardial fibrosis on ventricular remodeling following valve replacement for severe aortic stenosis. A CMR study comparing transcatheter aortic valve implantation and surgical aortic valve replacement
Myocardial fibrosis (MF) that occurs in aortic stenosis (AS) has been shown to be associated with a poor prognostic outcome post surgical aortic valve replacement (SAVR) but not in the high risk patients suitable for Transcatheter aortic valve implantation (TAVI). Using the technique of late-gadolinium enhancement we have shown that MF regresses post-TAVI but not postSAVR, and that ejection fra...

Introduction: With the development of interventional cardiology in the world, in addition to coronary and aortic diseases, the treatment of heart valve diseases through catheters has recently begun. The treatment of aortic stenosis (which was only possible with open surgery and valve replacement) was first performed in the world in 2002 by Alain Cribier in France with catheter insertion of the ...

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...

Mitral valve replacement (MVR) is usually performed in two methods of running and interrupted suturing. In running method, the suturing of the valve is usually with some traction on the annulus and also there is a risk of aortic valve injury. This study was conducted to evaluate a new technique for suturing to avoid these complications and decrease the time of cardiac arrest. One hundred an...
