Left ventricular remodelling and prosthetic valve function after transcatheter aortic valve implantation: A serial cardiac magnetic resonance imaging study
نویسندگان
چکیده
Background Transcatheter aortic valve implantation (TAVI) has become a common procedure for high-risk patients with severe aortic stenosis. Aortic regurgitation (AR) is commonly seen after TAVI, but little is known about how it evolves over time. Similarly, the impact of TAVI on left ventricular (LV) function, LV volumes and mass is not well defined.Paravalvular aortic regurgitation (AR) is frequent after TAVI. Yet, little data is available about temporal changes of AR and the impact of TAVI on left ventricular (LV) function and dimensions. We used cardiac MRI to evaluate LV function, volumes and mass, the occurrence and degree of AR in the early and medium-term follow-up after TAVI.

Left ventricular mass regression may occur very early following transcatheter aortic valve implantation for severe aortic stenosis
Background The effect of transcatheter aortic valve implantation (TAVR) on left ventricular remodelling early following valve implantation has not previously been evaluated using cardiac magnetic resonance (CMR). Early left ventricular mass (LVM) regression (assessed using echocardiography) has been linked to a 50% reduction in rehospitalisation in the first year following TAVR. We sought to es...
متن کاملLeft ventricular remodeling after transcatheter aortic valve implantation (TAVI)
Background Transcatheter aortic valve implantation (TAVI) offers a minimal invasive option for the treatment of patients with severe aortic stenosis at high risk for conventional surgery. The objective of this study was to investigate whether there is a positive effect on the left ventricular remodeling 6 month after transcatheter aortic valve implantation (TAVI) using cardiac magnetic resonanc...

BACKGROUND Aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) has been associated with poor outcomes, but little is known about how it evolves over time. We evaluated left ventricular (LV) function, remodeling, and the occurrence and evolution of AR after TAVI by using cardiac MRI. METHODS AND RESULTS Forty-three patients treated with transfemoral TAVI underwent ca...
متن کاملGender influences left ventricular remodelling in the setting of aortic stenosis but does not appear to impact on reverse remodelling following transcatheter aortic valve implantation
Background Left ventricular (LV) remodelling in the setting of the chronic pressure overload of aortic stenosis (AS) appears to differ according to gender. Women appear to have an improved survival compared to men following transcatheter aortic valve implantation (TAVI) but the reasons for this are yet to be established. Potential mechanisms include differing patterns of LV reverse remodelling,...

Background Transcatheter aortic valve implantation (TAVI) has been established as a therapeutic alternative in patients with severe aortic stenosis at high risk for surgery. Paravalvular aortic regurgitation (AR) is frequent after TAVI. Yet, little data is available about temporal changes of AR and the impact of TAVI on left ventricular (LV) function and dimensions. We used cardiac MRI to evalu...
