Removal of an inferior vena cava filter that had migrated to the right ventricle by off-pump ventriculotomy and direct-vision snare capture: a novel hybrid technique

Inferior vena cava filter (IVCF) migration to the right ventricle is a life-threatening condition. Conventionally, on-pump ventriculotomy is required if the endovascular retrieval is compromised. However, for patients in fragile physical condition, the complications of myocardial revascularization are unacceptable. We herein present a case of IVCF migration to the right ventricle in which the hook of the filter was tilted against the anterior wall of the right ventricle. The IVCF was successfully removed via a hybrid technique combining an off-pump microincision of the right ventricle with direct-vision snare capture. This hybrid technique avoided the complication of myocardial revascularization, shortened the operation time, and reduced the amount of blood loss.
