Iatrogenic aortopulmonary communications (IAPCs) are an uncommon but important complication after percutaneous intervention in postoperative patients. Iatrogenic aortopulmonary communications typically occur after balloon angioplasty or other interventions of the pulmonary outflow tract in certain anatomic configurations in which there is a denuded tissue plane between the pulmonary artery and aorta. They can present with signs and symptoms ranging from subtle clues which are difficult to recognize to near immediate hemodynamic instability. Once recognized, these lesions can become management dilemmas, and intraprocedural interventions can be complicated by complex anatomy and inadequate visualization by standard imaging techniques. We report cases where intracardiac echocardiography (ICE) was integral in the evaluation and management of IAPC as complications of prior transcatheter interventions. We found using ICE safely and effectively identified IAPCs and reduced the technical difficulty of intervention after IAPC discovery.
