Abstract
Background: Normal values for regional left ventricular wall motion, although documented in adults, have not been reported in healthy newborns. Methods: This study prospectively evaluated global and segmental systolic and diastolic cardiac function by color kinesis in clinically asymptomatic healthy newborns. Results: Eighty-eight asymptomatic infants who were less than 48 hours old were studied. Systolic and diastolic parameters of global and regional left ventricular function are reported as means ± SD, medians, 5th and 95th percentiles to establish the normative values for newborns. The reported fractional area changes during systole and diastole are similar to the reported normal values for older subjects. Higher body surface area significantly correlated with an increased peak velocity during systole, and fractional area changes during filling of the lateral wall. Conclusions: Our report of left ventricular regional wall-motion characteristics of healthy newborns, as evaluated by color kinesis, may help in the objective evaluation and management of newborns suspected to have global or segmental ventricular dysfunction.

Funding
We are thankful to the wonderful staff of General Clinical Research Center (grant from NIH #MO1RR00080 awarded to Case Western Reserve University) for their constant support and help in providing great care to our patients and their families. We are also grateful to Dr Victor Mor-Avi for his helpful comments and for his help in the color kinesis analysis. The study would not have been possible without the dedication and expertise of Maureen Babjak, Linda Wiersma, Cindy Holliday, and Allen Borowski.
