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...

OBJECTIVE: To compare the efficacies of various post-percutaneous coronary intervenetion (PCI) bivalirudin doses on net adverse clinical events (NACEs) and mortality. BACKGROUND: In primary PCI, lower risk of bleeding with bivalirudin (vs. unfractionated heparin [UFH]) is counterbalanced by an increased risk of acute stent thrombosis (ST). Several randomized clinical trials (RCTs) and a recent meta-analysis suggest that acute ST risk may be eliminated without compromising the bleeding benefit, but only if the full dose, not a low dose, of bivalirudin is continued post-PCI...
