Aortic Displacement of a Pulmonary Stent: Multidisciplinary Approach to Treat a Rare Complication.

BACKGROUND

Pulmonary vein (PV) stenosis is a rare complication of radiofrequency-based pulmonary vein isolation (PVI). Its therapy consists of PV stenting.

CASE SUMMARY: A 67-year-old woman underwent a thoracic computed tomography scan after left PV stenting for stenosis after PVI. The scan revealed the stent missing in the left inferior PV and worsening high-grade stenosis. An abdominal computed tomography scan identified the displaced stent in the aorta, just above the aortoiliac bifurcation. Digital subtraction angiography also revealed moderate stenosis in the right common iliac artery. A double stenting procedure of the aortoiliac bifurcation using the kissing stents technique was performed, securing the PV stent and treating the common iliac artery stenosis. Follow-up on the displaced stent was favorable.

DISCUSSION AND TAKE-HOME MESSAGE: PV stent systemic displacement is a rare but life-threatening complication of PV stenting. Kissing stents technique is effective to secure the displaced stent in the aortoiliac bifurcation.
