Right ventricular myocardial sinusoidal-coronary artery connections in critical pulmonary valve stenosis.

Abstract:

:Ventriculo-coronary arterial connections are frequently observed in pulmonary atresia with intact interventricular septum. Sustained right ventricular hypertension during cardiac morphogenesis is thought to be responsible for persistence of myocardial sinusoidal-coronary artery connections. Considering an unusual observation of ventriculo-coronary arterial connections in a patient with critical pulmonary valve stenosis, we speculate that sinusoidal connections in pulmonary atresia with intact ventricular septum occur not only because it is the only exit for blood from the blind right ventricle, but also because of intrinsic altered morphogenesis of the right ventricle myocardium.
