Echocardiography in congenital heart disease.

It has been demonstrated that echocardiography is a useful and accurate noninvasive technique for the study of congenital cardiovascular diseases. This method provides significant information in that invasive cardiac catheterization and angiocardiography can be planned with greater facility. This is especially important in severely ill babies in whom invasive diagnostic methods are risky. It is particularly attractive in neonates in whom the clinical differentiation of lethal heart disease from septic shock is difficult, since in the latter situation the echographic findings are normal.

COMPARISON OF CENTRAL AORTIC AND PERIPHERAL ARTERY PRESSURE CURVES.

Brachial artery and central aortic pressures were compared in 50 consecutive patients subjected to retrograde left heart catheterization in order to re-emphasize the fact that the two pressures are not necessarily identical. In 43 cases the systemic systolic pressure peaks exceeded those in the central aorta while in seven these pressures were equal. The average pressure difference was 22.6 mm. Hg. The greatest differences occurred in cases of aortic regurgitation and could be extreme, the brachial artery systolic pressure exceeding that in the aorta by more than 100 mm. Hg in some instances. The least differences occurred in cases of aortic stenosis but significant differences occasionally existed, leading to erroneous estimation of valve orifice size if the systemic rather than the aortic systolic pressure was used.

Echocardiography in congenital heart disease. An aid to surgical diagnosis.

Echocardiography is an important noninvasive method for accurately diagnosing many congenital cardiac defects. This method provides significant information so that cardiac surgery, when necessary, can be planned with greater facility. The value of the sonar method rests not only on its ability to diagnose specific cardiac defects but also to exclude heart disease, especially in infants with shock or cyanosis from noncardiac causes. Development of two-dimensional real-time scanning systems should provide greater understanding of anatomic spatial relationships and ease of diagnosis.
