A 40-year-old man underwent emergent pulmonary artery thromboembolectomy for pulmonary artery thromboembolism, and an ALN filter was placed in the inferior vena cava immediately after the operation. He had sudden ventricular tachycardia with dyspnea on postoperative day 6. An emergent operation was successfully performed, and the ALN filter was observed at the tricuspid valve with a large amount of the thrombus. Migration of the inferior vena cava filter to the right ventricle is a life-threatening complication that may result from residual deep vein thrombosis.
