Comparison of Left Ventricular Mass Calculation Methods via Two-Dimensional Echocardiogram in Children, Adolescents, and Young Adults With Systemic Hypertension
Section snippets
Methods
This study was approved by Cincinnati Children's Hospital Medical Center Institutional Review Board. We retrospectively reviewed 200 consecutive, initial echocardiograms for the indication of hypertension in patients 7 years of age and older, performed at Cincinnati Children's Hospital Medical Center. Cincinnati Children's Hospital Medical Center Echocardiography laboratory is an accredited Facility of the Intersocietal Accreditation Commission and performs approximately 18,000 total studies a
Results
A total of 200 consecutive echocardiograms were reviewed. There were 22 patients excluded; 1 patient was excluded for the previous diagnosis of dilated cardiomyopathy, 2 patients were excluded secondary to previously diagnosed congenital heart disease, and 19 patients were removed secondary to poor acoustic windows. Final analysis consisted of 178 patients (89%). Patient characteristics are provided on Table 1. Patient age ranged from 7 to 24 years of age. There was a moderate positive
Discussion
This study is the first to our knowledge to assess the difference in LV mass calculated with various 2D methods used in different pediatric echocardiography laboratories. Our results suggest an important variation within the different methods. Although overall paired comparison did not reveal a difference between PLA and PSA, 2D volumetric assessment demonstrated lower overall values, with fewer patients categorized with LV target organ damage and elevated LV mass.
Echocardiography is the
