Proximal right coronary artery stenosis Right coronary artery stenosis: Right coronary angiogram in LAO (left anterior oblique) cranial view shows proximal luminal irregularities with narrowest segment near the
Serial angiographic shots showing steps in device closure of patent ductus arteriosus (PDA). Though small PDAs can be closed by coil occlusion, larger ones require device closure.
Right coronary angiogram showing conus branch, sinus node artery, right ventricular branches, posterior descending coronary artery and the stump of posterior left ventricular branch.
Infective endarteritis is less likely in very small or large PDA as, a high velocity jet causing endothelial damage is unlikely. It is more likely in moderate sized
