Isolated Pulmonic Valve Endocarditis.

Isolated pulmonic valve infective endocarditis (PV-IE) is a rare form of endocarditis. The authors report a case of giant vegetations detected by transthoracic echocardiography (TTE) on PV in a young patient, 33-year-old, with drug abuse history. The patient underwent surgical intervention by pulmonary valved bioconduit implantation. After operation, a pulmonary embolism episode was treated by a direct oral anticoagulant. The final outcome was favorable. The difficulty in diagnosing PV-IE is due to the inability to properly visualize the PV by echocardiography. In this case, with such large vegetations, TTE allowed a correct diagnosis and an effective surgical planning, confirming its importance as a diagnostic tool.
