Embolization of the Stent to the Right Heart After a Motor Vehicle Accident

An Unusual Cause of Acute Heart Failure: A Case Report of Iliocaval Venous Stent Migration

Stent migration is an uncommon complication of endovascular stenting procedures. It could cause serious cardiovascular complications. In this article, we describe an interesting case of acute heart failure as a result of stent embolization from the left common iliac vein into the right ventricle and how it was identified and managed.

Severe tricuspid regurgitation due to valvular entrapment of an inferior vena cava stent

Endovascular venous stenting is increasingly performed for a variety of conditions. Inferior vena cava stent migration has been reported up to 6 months after placement; stent migration 6 months after implantation is uncommon. To our knowledge, this is only the second reported case of late stent migration with valve entrapment 1.

Foreign bodies in the heart

BACKGROUND

Foreign bodies in the heart are rare, may reach the heart by different ways, and cause serious complications. X-ray, computerized tomography, and echocardiography are main diagnostic modalities. Foreign body can be removed surgically, percutaneously or can be managed conservatively. In this work, we analyzed 100 published cases of a foreign body in the heart and 4 cases that were identified in our hospital.

METHODS

We searched the literature for foreign body in the heart and found 100 published previously cases. Additional 4 cases were identified in our echo laboratory. A total series of 104 patients with a foreign body in the heart were analyzed for the etiology, clinical presentation, symptoms, complications and management.

RESULTS

Mean patients' age was 46, there were more men than woman 73 versus 31 [P < 0.00005]. The most common foreign bodies were parts of inferior vena cava filters and devices implanted for relieving hydrocephalus. Foreign bodies in the heart were symptomatic in 56% of patients. Right heart chambers were occupied more often. A total of 20% presented within the first 24 hours and 30% of patients presented years after the penetration of the foreign body. A majority of foreign bodies reached the heart by migration [88%]. Mortality was reported in 4 patients [3.8%]. Here 54% of the patients underwent surgical and 29% percutaneous removal of the foreign body, while 14% were followed conservatively.

CONCLUSION

Foreign bodies in the heart may present with a wide variety of symptoms. Physicians should be aware of this rare and peculiar complications which may be fatal. Larger devices may result in more severe complications.

Management of metallic foreign bodies in the heart

Management of the metallic foreign body in the heart remains controversial. Evaluation of possible methods for this issue and its possible treatments are discussed, the results of which may lead to a more effective strategy for management of intracardiac foreign bodies.
