Biventricular perforation by a temporary pacing electrode: recognition from the lateral chest radiograph.
A temporary pacing electrode was inserted in a patient with severe calcific aortic stenosis complicated by complete atrioventricular block. Despite normal pacing and sensing function, a diagnosis of myocardial perforation was made on the basis of a lateral chest radiograph. Neither the surface electrocardiogram nor the frontal chest radiograph suggested evidence of myocardial perforation, and echocardiographic diagnosis was limited by poor echogenicity of the patient. Biventricular perforation with pericardial effusion were documented at operation.
