The effect of adenoidectomy on right ventricular performance in XXXX .

@entity1 @entity551 @entity1184 @entity1224
OBJECTIVE: Several studies have shown a @entity551 (PAP) after adenoidectomy in @entity1 suffering form @entity1224 caused by @entity1184 ( @entity1184 ). However, it is not clear whether this would be significantly reflected on right ventricle output (RVO). METHODS: Our aim was to determine if there were any detectable changes in RV performance parameters after adenoidectomy in @entity1 with @entity1184 . Thirty @entity1 with @entity1184 (female/male: 11/19) aged between 2.5 and 12 years (median: five years) were included in this study. Adenoidectomy was performed under sinuscopic guide using adenoid curette and microdebrider. All @entity1 were examined by echocardiography one day before and one month after adenoidectomy. Velocity time integral of tricuspid valve flow (VTItv) and pulmonary valve flow (VTIpa); E/A ratio of tricuspid valve flow; RV end-diastolic diameter (RVEDd) and left ventricle fraction shortening (FS) were measured. Heart rate (HR) was also recorded. RESULTS: Preoperatively VTItv, VTIpa, E/A ratio, RVEDd, FS, and HR were 18.6+/-3.0 cm, 20.8+/-3.1 cm, 1.21+/-0.31, 11.5+/-2.1 mm, 35.1+/-4.3%, and 112+/-19, respectively. Postoperatively VTItv, VTIpa, E/A ratio, RVEDd, FS, and HR were 21.5+/-2.5 cm, 24.4+/-4.3 cm, 1.44+/-0.32, 9.3+/-2.6 mm, 33.9+/-3.5%, and 104+/-28, respectively. There were significant differences between preoperative and postoperative VTItv (p=0.03), VTIpa (p=0.01), E/A ratios (p=0.04), and RVEDd (p=0.01). FS and HR were not significantly different. CONCLUSIONS: This study illustrated that in @entity1 suffering from @entity1184 , relieving @entity1224 by adenoidectomy may result in improvement of RV filling and RVO, associated with the reduction in PAP.
