Haemodynamic differences between two generations of a balloon-expandable transcatheter heart valve

Zusammenfassung: | ObjectivesThis study aimed to investigate early haemodynamic and clinical performance of the SAPIEN 3 Ultra (S3 Ultra) transcatheter heart valve (THV) system in comparison to its precursor, the SAPIEN 3 (S3). Previous studies have indicated potential haemodynamic differences between the S3 Ultra and S3. Such differences may impact clinical outcome after transcatheter aortic valve implantation (TAVI).MethodsPostprocedural haemodynamic performance and 30-day clinical outcome were compared in patients who underwent TAVI receiving either the S3 or the new S3 Ultra prostheses. Multivariable analysis and propensity score matching (PSM) were used to identify factors associated with higher mean transvalvular gradients.ResultsWe included 697 patients (S3 Ultra: n=314, S3: n=383) from the multicentre RhineHeart TAVI Registry. Patients receiving the S3 Ultra prosthesis showed significantly higher postprocedural mean transvalvular gradients (14.2±4.8 vs 10.2±4.4 mm Hg; p |
