Prothesis obstruction after mechanical cover replacement is a complication that is rare but can lead to serious consequences. The main causes of mechanical cover obstruction include cover thrombosis, panus formation and vegetation. This article discussed the phenomenon and treatment of the mechanical mitral cover replacement that has been accepted and obstructed by large vegetation and panus formation and the hemo-cultural negative cover endocarditis. Two years ago, a 36-year-old man with a mechanical aort and mitral coating replacement surgery appeared to the clinic with breathing difficulties and high fever complaints. The patient had ortophenic, tachypne, tachycardia and high fever. In the physical examination, pretibial obesity, hepatomegaly and bilateral lungs krepitation were detected. In the mitral area there was 3/6 systolic swelling. In the transtoral and transozofageal ecocardiography, the mechanical mitral cover subtotal-touching 3,1x0,7cm-sized vegetation-like mobile mass appearance was detected. The patient was diagnosed with hemoculture negative protez cover endocarditis. In the surgery, mechanical mitral cover proteins were found in a close obstruction with large vegation and panus formation. The mitral cover was scratched and the component was replicated with a mechanical cover. There were no problems in the long-term follow-up of the patient who received intensive care with intrusive support. The preoperative antibiotic treatment was continued for 4 weeks. Mechanical cover protection is a post-replace of vegetation and panus formation that can cause serious complications. The results of surgery combined with early aggressive antibiotic therapy are face laughing.
