This four chamber view of a heart with pulmonary atresia and intact ventricular septum demonstrates a hypoplastic right ventricle (HRV) with a right coronary artery (RCA) to right ventricular (RV) fistula. The right coronary artery is dilated and thick walled along nearly its entire length. The interventricular septum is thin and there is an Ebstein-like malformation of the septal leaflet of the tricuspid valve (TV). The septal leaflet is adherent to the septum along is entire length (black arrows). (A-aorta, LV-left ventricle, MV-mitral valve)
This superior view of a heart with pulmonary atresia and intact ventricular septum (not shown) demonstrates an atretic pulmonary artery (PA) with a left coronary artery (LCA) to right ventricular fistula (not shown). The left coronary artery is dilated along nearly its entire length.
a, Schematic of a heart with pulmonary atresia and intact ventricular septum (PA-IVS) and the tissue blocks that were taken for immunohistochemical study. b, Drawing of a heart with PA-IVS, demonstrating the location of the main connection sites of ventriculo–coronary arterial communications (thick black lines). c, Drawings of the individual hearts that were studied to demonstrate the sites of ventriculo–coronary arterial communications (thick black lines), interruptions of the subepicardial coronary arteries (asterisks), and the tissue blocks that were taken for immunohistochemical evaluation (rectangles). Ao indicates aorta; LAD, left anterior interventricular artery; LCx, left circumflex branch; prox, proximal; RCA, right coronary artery; RPD, right posterior interventricular artery. Panels b and c are modified from Gittenberger-de Groot et al.5
