T1 mapping, ECV and ICV before and after aortic valve replacement
Methods A prospective CMR T1 mapping study of 37 patients with severe AS before and six months after aortic valve replacement (AVR) was conducted. CMR at 1.5 T, including T1 mapping using a modified Look-Locker inversion recovery sequence (before and 15 minutes after the administration of 0.2 mmol/kg of Gadoteric acid), was carried out. Global T1 values, ECV, ICV have been measured before and s...
متن کاملLeft ventricular myocardial structure in aortic valve disease before, intermediate, and late after aortic valve replacement.
Left ventricular biplane cineangiography, micromanometry, and endomyocardial biopsies were performed in 27 patients with aortic stenosis (AS) and in 17 patients with aortic insufficiency (AI). Twenty-three patients with AS and 15 with AI were restudied at an intermediate time (18 months after successful valve replacement), and nine patients with AS and six with AI were restudied late (70 and 62...

متن کاملPre- and post-contrast T1 mapping for detection of myocardial fibrosis in severe aortic stenosis before and after aortic valve replacement
Background Severe aortic stenosis (AS) leads to diffuse fibrosis in the myocardium, which could cause poor clinical outcome. Cardiovascular Magnetic Resonance (CMR) with recently T1 mapping is a promising technique to identify diffuse myocardial fibrosis. The Objective of the present study was to assess myocardial fibrosis by CMR using T1 mapping in patients with surgical AS and evaluate the ev...
متن کاملDiastolic stiffness and myocardial structure in aortic valve disease before and after valve replacement.
Passive diastolic properties were determined in 10 control patients and 21 patients with aortic valve disease before and 17.5 months after successful valve replacement. Ten patients had severe aortic stenoses (AS), five had combined aortic valve lesions (AS + aortic insufficiency [AI]), and six patients had severe AI. Left ventricular endomyocardial biopsies were obtained before and after surge...
