Human and murine fibroblast single-cell transcriptomics reveals fibroblast clusters are differentially affected by ageing and serum cholesterol.

Aims: Specific fibroblast markers and in-depth heterogeneity analysis are currently lacking, hindering functional studies in cardiovascular diseases (CVDs). Here, we established cell-type markers and heterogeneity in murine and human arteries and studied the adventitial fibroblast response to CVD and its risk factors hypercholesterolaemia and ageing.

Methods And Results: Murine aorta single-cell RNA-sequencing analysis of adventitial mesenchymal cells identified fibroblast-specific markers.

A systematic review and meta-analysis of the cerebrovascular event incidence after transcatheter aortic valve implantation.

Objective: Periinterventional stroke is one of the most feared potential complication, among patients treated with transcatheter aortic valve implantation (TAVI). The purpose of this review was to investigate the incidence of cerebrovascular events and the influence of postinterventional neurologic check-up in patients undergoing TAVI.

Methods: A systematic review and meta-analysis were conducted according to the PRISMA guideline.
