Zusammenfassung
Ziele: To retrospectively investigate the potential cause of contained rupture of the aortic root in balloon-expandable transcatheter aortic valve implantation (TAVI) by means of pre- and post-interventional multi-slice computed tomography (MSCT). Methode: Seventy-two patients (mean age 82±7 years, mean aortic valve area 0.69±0.19cm2) underwent balloon-expandable TAVI using the EdwardsSAPIEN Transcatheter Heart Valve (23mm, n=19; 26mm, n=50; 29mm n=3). Aortic annulus dimensions were quantified by MSCT-based cross-sectional area assessment and average diameter calculation (CAAD) prior and after TAVI. Post-TAVI MS…
