There are several methods for surgical management of aortic insufficiency in patients with end-stage congestive heart failure who are undergoing implantation of a left ventricular assist device (LVAD). To date, little is known about the long-term outcome of bioprosthetic valves for aortic insufficiency in patients with continuous flow LVADs. We report on(More)
BACKGROUND As outcomes for destination therapy continue to improve, many patients are requiring left ventricular assist device (LVAD) exchange due to end-of-life of their LVAD. Current techniques to identify and diagnose device end-of-life issues usually require invasive testing or off-site filter dust analysis. In this study we assess a non-invasive(More)
Sustained myocardial recovery and reversal of heart failure has been reported with the use of left ventricular assist devices (LVADs). However, clinical predictors of sustained recovery have not been clearly defined, and little information exists regarding exercise improvement in LVAD patients. Therefore, we sought to determine whether peripheral oxygen(More)
The occurrence of allergic rhinitis, asthma and otitis media was examined in 395 Indian children living on two separate reservations in Arizona. The children were followed from birth to age 5 years in a study of otitis media. On retrospective review of medical records, 45% of the children at Parker had a clinical diagnosis of allergic airway disease, in(More)
Language performance was evaluated in 167 healthy Apache Indian children aged 6 to 8 years, who had contrasting histories of otitis media and who had been followed since birth. All children received pneumatic otoscopy, tympanometry, pure tone audiometry, and a battery of language measures. Groups were similar with respect to age, sex, school experience,(More)
More than 75 percent of the cases of acute suppurative otitis media (ASOM) among Indian children observed from May 1974 through March 1979 were experienced by preschool children. About 60 percent of the children observed during the first year of life had one or more attacks of ASOM, and 34 percent had two or more. Among those who had ASOM before their first(More)
Studies were conducted to assess the relation of environmental and behaviora factors to occurrence of acute suppurative otitis media (ASOM) among four populations of Indian children in Arizona. Episodes of ASOM were recorded for 1,428 children observed during the first year of life. Data obtained on the households and premises of these children included(More)
Cleft uvula occurs in approximately 20% of Athabaskan Indians. The association of cleft uvula with otitis media was examined in a cohort of 175 Apache Indian children followed up prospectively from birth. No association was found between the occurrence of cleft uvula and the rate, frequency, or timing of otitis media attacks.
