Constrictive Pericarditis: Etiologic Spectrum, Patterns of Clinical Presentation, Prognostic Factors, and Long-term Follow-up.
Some reports have described a change in the etiologic spectrum of constrictive pericarditis. In addition, data on the relationship between its clinical presentation and etiology are lacking. We sought to describe the etiologies of the disease, their relationship with its clinical presentation and surgical findings, and to identify predictors of poor outcome. ⋯ Most cases of constrictive pericarditis are idiopathic. Cardiac surgery and radiation accounted for a minority of cases. Etiologic investigations are warranted only in acute or subacute presentations. Age, advanced functional class, and previous acute idiopathic pericarditis are associated with increased mortality.

Safety and Efficacy of New Sirolimus-eluting Stent Models in a Preclinical Study.
Initial preclinical studies are required during the process of improving polymers, platforms, and drug-eluting systems for new coronary stent designs. Our objective was to analyze the efficacy and safety of new drug-eluting stent models compared with a conventional stent and commercialized drug-eluting stents in an experimental model with healthy porcine coronary arteries. ⋯ The new drug-eluting stent platforms studied are associated with less restenosis than conventional stents and showed no significant differences in safety or efficacy vs commercialized drug-eluting stents.
