Congenital complete heart block. Radiographic findings in 13 patients without associated defects
RB Jaffe, SA Sherman, VR Condon, RE Romm and LG Veasy
The radiographic findings in 13 patients with congenital complete heart
block without associated anomalies are presented to illustrate
characteristic features. Findings related to the increased stroke volume in
these patients include: (a) simulated shunt vasculature; (b) pulmonary
venous pypertension with redistribution of blood flow to the upper lungs,
and, in one patient, peribronchial edema; (c) cardiomegaly with right
ventricular, pulmonary artery, left atrial, left ventricular, and aortic
enlargement; and (d) variation in cardiac size on serial examinations. Less
commonly seen were findings related to atrioventricular dissociation with
transitory marked pulmonary venous hypertension present in one patient when
left atrial contraction occurred during ventricular systole when the mitral
valve was closed.
