(fig 2a). A right atrial cineangiogram showed direct emptying of the contrast material into the left ventricle via the primum atrial septal defect and common atrioventricular valve (fig 2b). The left atrium was simultaneously opacified, unlike classic tricuspid atresia in which there is sequential opacification of the right atrium, left atrium, and left ventricle. The right ventricle was not directly opacified from the right atrium. The child underwent a right BlalockTaussig shunt which improved systemic arterial oxygen saturation (84%).

ObjectiveVentricular fibrillation remains as the major cause of death in patients with acute myocardial infarction. Effects of trans‐atrial chemical ablation of the left ventricular (LV) endocardium with Lugol's solution on ventricular fibrillation inducibility and ventricular conduction were examined in canines with acute myocardial ischemia.Materials and MethodsChemical ablation of the LV endocardium with Lugol's solution or normal saline was preformed through a left atrial appendage in 14 canines 30 min after occlusion of the left anterior coronary artery.ResultsVentricular fibrillation threshold decreased after the coronary artery occlusion and increased after endocardial chemical ablation. There was a significant difference in the ventricular fibrillation threshold after chemical ablation between with Lugol's solution and with normal saline (25.9 ± 9.2 mA vs. 11.3 ± 2.7 mA, p < .01). QRS width significantly increased from 88 ± to 116 ± (p < .01) after the chemical ablation with Lugol's solution, and the activation map of the ventricles demonstrated a left bundle branch block ventricular conduction pattern. Histological examination of the LV endocardium showed lymphocyte infiltration for a depth of 1 mm.ConclusionsChemical ablation of the LV endocardium with Lugol's solution injures endocardial conduction system and increases ventricular fibrillation threshold in the early phase of myocardial ischemia in canines. The procedure may be useful in suppressing intractable ventricular tachyarrhythmias in patients with acute myocardial ischemia.
