[Value of two-dimensional Doppler color echocardiography in mitral-ventricular-aortic obstructive disease in the newborn].

Over the last years, the bidimensional echocardiography has assumed an increasingly impact in the management of heart disease in neonates. With the addition of Doppler technique and color flow mapping this non invasive method provide the most accurate definition of cardiac anatomy and physiology. It is particularly true in newborns with left inflow or outflow obstruction disease such as: pulmonary vein stenosis, divided left atrium, mitral and aortic stenosis or atresia, subvalvular narrowing, and hypoplastic left ventricle and aortic tract. The combination of these two methods contribute to recognize a specific left cardiac abnormalities and allow us to evaluate the therapeutical success in the follow up period.
