To these data we have linked a cardiac surgery clinical database and our physician billing data (inpatient and outpatient). Other(More)
Blastomyces dermatitidis is a fungus that is found primarily in endemic areas of the midwestern and southcentral USA. Blastomycosis pneumonia may develop after the inhalation of spores. While blastomycosis may lead to acute or chronic pneumonitis, it will rarely result in the development of the acute respiratory distress syndrome (ARDS). In this situation,(More)
Heparin and nitric oxide (NO) attenuate changes to the pulmonary vasculature caused by prolonged hypoxia. Heparin may increase NO; therefore, we hypothesized that heparin may attenuate hypoxia-induced pulmonary vascular remodeling via a NO-mediated mechanism. In vivo, rats were exposed to normoxia (N) or hypoxia (H; 10% O(2)) with or without heparin (1,200(More)
Our programmatic approach to the Fontan operation has evolved to include using an extracardiac conduit with aggressive presumptive treatment of associated lesions either in the catheterization laboratory or the operating room. Fenestration is used selectively based on hemodynamics, anatomy, and presence of associated lesions. We reviewed our experience to(More)
