Spontaneous echo contrast, left atrial appendage thrombus and stroke in patients undergoing transcatheter aortic valve implantation.

ABSTRACT:

Aims

The relevance of spontaneous echo contrast (SEC) and left atrial appendage thrombus (LAAT) in patients undergoing transcatheter aortic valve implantation (TAVI) remains unclear. In this study, we aimed to assess the prevalence of SEC and LAAT and evaluate the impact on periprocedural outcome after TAVI.

Methods and results

A total of 2,549 consecutive patients underwent TAVI between 2008 and 2017. After exclusion of cases with insufficient imaging, concomitant procedures or severe intraprocedural complications, 1,558 cases were analysed. Three groups were defined according to (pre)thrombotic formations - moderate or severe SEC (n=89), LAAT (n=53), and reference (n=1,416). The primary outcome was disabling ischaemic stroke within 24 hours. The prevalence was 4.4% for LAA
