Heterogeneity of debris captured by cerebral embolic protection filters during TAVI.

ABSTRACT:

Aims

The aim of this study was to investigate the total amount, size and heterogeneity of debris captured among different transcatheter valve types and while repositioning.

Methods and results

A total of 328 patients who underwent transcatheter aortic valve implantation (TAVI) with the SENTINEL cerebral embolic protection (CEP) at our centre were eligible. Histopathological and semiquantitative analysis of captured debris was performed and data were entered into our prospective database. TAVI was performed with either the Evolut R/PRO (N=123), SAPIEN 3 (N=113) or Lotus valve (N=92). Capture of debris occurred in 98% of patients. Lotus TAVI resulted in more frequent foreign body material (62% vs 40% vs 47%, p=0.006), endothelium (49% vs 30% vs 16%, p<0.0005), calcified materi
