Early stent thrombosis is a rare complication of percutaneous intervention and is associated with significant 30-day mortality. We present a novel case of multiple recurrent early stent thrombosis consistent with spontaneous vaccine-induced thrombotic thrombocytopenia. We were successfully able to manage this unusual condition through an interdisciplinary collaboration.

Transcriptional signals in peripheral blood mononuclear cells allow for the development of multigene-based panels that can inform on the presence or absence of immunologic quiescence. The informative genes represent several biologic pathways, including T-cell activation (PDCD1), T-cell migration (ITGA4), and mobilization of hematopoietic precursors (WDR40A and microRNA gene family cMIR), and steroid-responsive genes such as IL1R2, the decoy receptor for interleukin 2.

In this review, we discuss contemporary directions in the knowledge base for managing geometric mitral regurgitation.
Recent Findings: Much progress has been encountered in describing the types of geometric mitral regurgitation (nonischemic and ischemic origins), standardization of echocardiographic techniques to allow for a common language in ascertaining the severity of mitral regurgitation, knowledge on dynamic mitral regurgitation during exercise, effectiveness of therapy and appropriate use and timing of surgical repair.
