PURPOSE: The purpose of this study is to identify the prevalence, location, and size of enlarged mediastinal lymph nodes in @entity1 with chronic @entity712 and to correlate the presence of @entity1600 with cardiac ejection fraction. METHODS: Sixty-six consecutive, retrospectively identified @entity1 underwent computer tomography (CT) imaging of the thorax as part of a routine work-up prior to cardiac transplantation from 1993 to 1996. CT images of 44 of these @entity1 were independently examined by 3 radiologists for evidence of @entity3126 , @entity1143 , and the presence, size, and location of lymph nodes >1 cm in @entity851 . Multigated acquisition (MUGA) scans were available for cardiac ejection fraction assessment in 38 of the 44 @entity1 . RESULTS: Twenty-nine (66%) @entity1 had at least 1 mediastinal lymph node >1 cm. The mean ejection fraction was significantly less for @entity1 with @entity1600 when compared with @entity1 without @entity1600 (20% versus 35%; P < 0.01). Adenopathy was observed in 81% of @entity1 with a calculated ejection fraction of <35%. No @entity1 with an ejection fraction of >35% had @entity1600 . There was no correlation between @entity3126 and the frequency of lymph node appearance. Sixty-three percent of the enlarged nodes were pretracheal, with a mean @entity851 diameter for all the enlarged nodes of 1.3 cm. CONCLUSIONS: Enlarged mediastinal lymph nodes were observed in 81% of @entity1 with a calculated ejection fraction of <35%, most commonly in the pretracheal group. The presence of the lymph nodes did not correlate with CT evidence of @entity3126 .
