Desplazamiento de stent de fístula arteriovenosa a cavidades cardíacas derechas: reporte de caso

A 35-year-old male patient undergoing hemodialysis presented with thrombosis of the arteriovenous fístula in the right upper limb, managed 5 days prior to admission by interventional radiology with thrombectomy and stent placement. He presented with atypical chest pain with occasional palpitations, and admission troponin was positive. An echocardiogram revealed a foreign body in the right cardiac chambers, suggestive of stent displacement. The interventional radiology service performed stent retrieval via the femoral route. During this procedure, the patient experienced electrical activity without a pulse and signs of cardiac tamponade, managed by pericardiocentesis with return of spontaneous circulation, he was then transferred to the intensive care unit. A subsequent transthoracic echocardiogram showed severe tricuspid regurgitation of organic etiology, it was managed by Cardiovascular Surgery service through tricuspid valve plasty and patch od a right venricle perforation. This case is noteworthy due to the uncommon occurrence of stent displacement from a dialysis arteriovenous fístula to right cardiac chambers and the presentation of two severe complications (tamponade because right ventricular perforation and valvular damage) during percutaneous retrieval.
