Blood flow pattern in the ascending aorta after TAVI and conventional aortic valve replacement: Analysis using 4D-Flow MRI
نویسندگان
چکیده
Background Transarterial aortic valve implantation (TAVI) is a valid alternative to treat aortic stenosis in patients with high surgical risk. The impact of TAVI on changes in blood flow dynamics in the ascending aorta has not been systematically analyzed. Using temporally resolved, three-dimensional, phase contrast MRI (4D-flow), we studied 3D hemodynamics in the ascending aorta (AAo) after TAVI and compared the results to patients with conventional aortic valve replacement (AVR) as well as healthy controls.

We present findings in a 79-year-old man after transcatheter aortic valve implantation (TAVI) for severe symptomatic aortic stenosis using a 26-mm Edwards Lifesciences Sapien 9000TFX valve.1 His predicted risk of operative mortality (Society of Thoracic Surgery score) was 12% on the basis of the following comorbidities: 2 previous coronary artery bypass operations, New York Heart Association fu...
متن کاملType of aortic valve replacement influences ascending aortic flow characteristics - a pilot study using 4D flow MRI
Methods Flow-sensitive four-dimensional magnetic resonance imaging (4D-flow) was acquired in 38 AVR patients (n=9 mechanical, n=8 stentless bioprosthesis, n=14 stented bioprosthesis, n=7 autograft) and 9 healthy controls. Analysis included grading of vortex and helix flow (0-3 point scale), assessment of systolic flow eccentricity (1-3 point scale), and quantification of the segmental distribut...

Materials and methods Maximal flow velocities (Vmax) and flow volumes (SV) were quantified by 2D and 4D VEC MRI in healthy volunteers (n=7) and patients with aortic (n=7) or pulmonary valve stenosis (n=10). Measurements were performed immediately above the aortic or pulmonary valve (=level 1). Using 4D VEC MRI additional measurements were performed at 3 further levels in the ascending aorta (le...

Methods In-vivo aortic 3D hemodynamics were evaluated by MRI in 17 patients with unicuspid (n=3), bicuspid (n=9, 3 true bicuspid, 3 right-left (RL) coronary leaflet fusion, and 3 right-non (RN) coronary leaflet fusion), trileaflet (n=3), and quadricuspid aortic valves (n=2). Valve morphology and dynamics were assessed using 2D CINE MRI. Aortic blood flow was measured using ECG and respiration s...

Methods Peak velocities (Vmax) and stroke volumes (SV) were quantified by 2D and 4D VEC MRI in volunteers (n=7) and patients with semilunar valve stenosis (n=18). Measurements were performed immediately above the aortic or pulmonary valve with both techniques (=level 1) and, additionally, at further predefined planes in the ascending aorta and in the pulmonary trunk within the 4D dataset. 4D VE...
