Mitral and tricuspid valve anular diameter in normal children determined by two-dimensional echocardiography. 1985

D H King, and E O Smith, and J C Huhta, and H P Gutgesell

To establish normal values for atrioventricular valve anular diameter in children, we measured the diameter of the mitral and tricuspid valve anuli from 2-dimensional echocardiograms in 103 children aged 1 day to 15 years. Measurements of the mitral valve anulus were made from the parasternal long axis and the apical or subcostal 4-chamber views. The tricuspid valve was measured from the subcostal or apical 4-chamber view. Multiple regression analyses were performed comparing valve anular diameter to weight and body surface area and their respective square root, cube root and logarithmic functions. Mitral and tricuspid anular diameter increased in proportion to the logarithm of weight and body surface area. The best predictor of valve anular diameter was a logarithmic function of body surface area with a calculated correlation coefficient ranging from 0.90 to 0.93 for the 3 anular dimensions. Knowledge of the normal atrioventricular valve anular diameter should be useful in planning palliative or corrective surgery in children with congenital heart disease.

D007223	Infant	A child between 1 and 23 months of age.	Infants
D007231	Infant, Newborn	An infant during the first 28 days after birth.	Neonate,Newborns,Infants, Newborn,Neonates,Newborn,Newborn Infant,Newborn Infants
D008943	Mitral Valve	The valve between the left atrium and left ventricle of the heart.	Bicuspid Valve,Bicuspid Valves,Mitral Valves,Valve, Bicuspid,Valve, Mitral,Valves, Bicuspid,Valves, Mitral
D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
