ABSTRACT

Infective endocarditis is one of the most rare complications of patent ductus arteriosus (PDA). Usually vegetations are localised at the level of the patent ductus and can involve the left branch and the trunk of the pulmonary artery. We report the case of a young woman with PDA, who was admitted to the hospital in severe congestive heart failure due to infective endocarditis. A 2D echocardiographic examination revealed vegetations into the ductus with extension to the pulmonary artery, pulmonary valve and aortic valve. The results of the echocardiographic study enabled us to evaluate the extension of the lesions, to avoid heart catheterization and to decide the most suitable surgical approach for repairing all the damage in one surgical operation.
