title: Endovascular repair of ventricular assist device outflow cannula stenosis.
abstract: This report describes a case of endovascular repair of an outflow cannula obstruction in a heart failure patient with biventricular assist devices. The patient presented with cardiogenic shock and was diagnosed via multimodality imaging with outflow cannula obstruction of the left ventricular assist device, likely from a hematoma. A transesophageal echocardiogram-guided endovascular approach was undertaken. A 10.0 mm × 38 mm covered stent was successfully deployed and post-dilated. Normal flow in the outflow cannula was restored. Hemodynamic and left ventricular flow parameters returned close to baseline post-procedure. The growth in ventricular assist device implantation and associated complications will create new opportunities for endovascular repair. © 2016 Wiley Periodicals, Inc.
