Intracardiac migration of a transjugular intrahepatic portosystemic shunt (TIPS) stent is a rare but potentially life-threatening complication. A 52-year-old man developed asymptomatic nonsustained ventricular tachycardia within 24 hours of elective TIPS creation. Echocardiography demonstrated a migrated TIPS bare-metal stent segment protruding into the right ventricle and interacting with the tricuspid valve. The stent was retrieved endovascularly using balloon and snare techniques via dual venous access under echocardiographic and fluoroscopic guidance. Arrhythmias resolved after stent removal. This case highlights the importance of early post-TIPS monitoring and prompt endovascular intervention for intracardiac stent migration presenting with ventricular arrhythmias.
