Abstract

Valvar regurgitation has been commonly found by echocardiography in adults and older children with normal hearts, but there is limited knowledge in neonates. To evaluate the prevalence of valvar regurgitation and analyze risk factors, echocardiography was performed on 975 consecutive neonates (1–7 days of age) with normal hearts. Regurgitation was detected and graded with pulsed, continuous-wave and color Doppler imaging techniques. Thirty-five cases with valvar regurgitation were followed for one month. The results showed that 369 (37.8%) neonates had evidence of regurgitation in one or more valves. Tricuspid regurgitation was most commonly found and was detected in 345 (35.4%) neonates, mitral regurgitation in 51 (5.2%), pulmonic regurgitation in 25 (2.6%), and aortic regurgitation in eight (0.8%). Most of them were trivial or mild and involved just one valve. Moderate or severe regurgitation was detected only in the tricuspid valve (3%) and the mitral valve (0.1 %). Five (0.5%) neonates with severe tricuspid regurgitation had heart murmurs, and two (0.2%) of them presented with cardiorespiratory distress. The risk factors for tricuspid and mitral regurgitation included lower chronologic age, gestational age and whether the neonates had a patent arterial duct; whereas those for tricuspid regurgitation also related to lower Apgar scores, birth weight and whether the neonates had a patent oval foramen. About 90% of the tricuspid regurgitation disappeared and the remaining 10% decreased in one month. We concluded that trivial or mild valvar regurgitation is commonly found in neonates with normal hearts. Moderate or severe regurgitation is relatively rare and occurs only in the tricuspid and mitral valves with a few cases causing clinical attention.
