Inferior vena cava filter (IVCF) placement has been recommended by clinicians for patients with venous thromboembolism who are at high risk for pulmonary embolism. There are a number of complications with IVCF insertion, removal, and migration that have been reported in the literature. Although those resulting from structural failure are rare, they can also be among the most critical. We describe a 48-year-old woman with a history of hypercoagulability whose IVCF fractured during retrieval, resulting in partial embolization to the right middle lobe pulmonary artery.

Multicenter Study Comparative Study
Postoperative atrial fibrillation after isolated aortic valve replacement: a cause for concern?
Several studies have shown that postoperative atrial fibrillation (POAF) is associated with poorer short-term and long-term outcomes after general cardiac operations. There is, however, a paucity of data on the impact of POAF on outcomes after isolated aortic valve replacement (AVR). ⋯ POAF is a risk factor for short-term morbidity but is not associated with a higher rate of early or late mortality after isolated AVR.

Significance of postoperative acute renal failure after continuous-flow left ventricular assist device implantation.
Deteriorating renal function is common in patients with advanced heart failure and is associated with poor outcomes. The relationship between renal function and left ventricular assist device (LVAD) implantation is complex and has been explored in multiple studies with contradictory results. The aim of our study is to examine the significance of postoperative renal failure after implantation of a continuous-flow LVAD and its relationship to outcomes. ⋯ Patients in whom ARF developed after LVAD implantation had a higher rate of VDRF and RV failure and a longer length of stay (LOS). Postoperative ARF was associated with higher mortality at the 30-day, 180-day, and 360-day intervals. ARF after LVAD may be an early marker of poor outcome, particularly RV failure, and may be an opportunity for early intervention and rescue.
