TL;DR: Stem cells harvested from blood or marrow, whether administered as purified HSCs or mesenchymal stem cells or as an unmanipulated or unpurified product can provide disease-ameliorating effects in some autoimmune diseases and cardiovascular disorders.

TL;DR: Predictive models that can identify patients at high risk for a poor outcome after TAVR are developed and validated and may help guide treatment choices and offer patients realistic expectations of outcomes based on their presenting characteristics.
Journal ArticleDOI
