Dyspnea and hypoxemia are common postoperative problems after pneumonectomy. One of the rarer causes of respiratory distress after right pneumonectomy is the development of a significant right-to-left shunt across a patent foramen ovale (PFO), which can evolve at a variable interval of time after the operation. We report here our experience with a patient who underwent right pneumonectomy, followed by several complications, and who presented severe dyspnea 7 months later, after the closure of a right thoracostomy. This report outlines the management of this challenging clinical condition; transesophageal echocardiography (TOE) provided a clear diagnosis and guided an effective percutaneous treatment.
Keywords: patent foramen ovale; percutaneous intervention; three-dimensional transesophageal echocardiography; transesophageal Echocardiography.
