A 69-year-old woman presented to the emergency department for symptoms of acute right heart failure including progressive exertional dyspnea and limbs weakness. Physical examination showed slight cyanosis and cold limbs. She underwent percutaneous transcatheter closure of a secundum ASD through femoral vein eight months before. On further investigation, transthoracic echocardiography (TTE) revealed severe tricuspid regurgitation and the migrated ASD device (Figure 1), and the embolization seemed to be located near the left ventricular inflow tract. Computed tomography (CT) and three-dimensional reconstruction confirmed the left-side migration of the device, and revealed obstruction of RPV caused by the embolization (Figure 2).
