The PAPi is a simple, invasive hemodynamic measure that may help identify high-risk patients with acute IWMI with severe RVD. Earlier identification of this high-risk population may improve clinical outcomes.

Anomalous papillary muscle insertion directly into the surface of the mitral valve leaflet is rare, especially in a subject without apparent evidence of hypertrophic cardiomyopathy. We present a case of this isolated congenital malformation producing two hemodynamic sequelae of dynamic left ventricular outflow tract obstruction and severe mitral regurgitation.

Rescue techniques that enable removal of severe intravascular catheter kinking are always worthwhile. We herein demonstrate the novel employment of a GuideLiner support catheter to assist in the removal of a kinked and entrapped guide catheter within the radial artery during coronary intervention. © 2016 Wiley Periodicals, Inc.
