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.

Device malposition and dysfunction with resultant severe aortic insufficiency are known complications of transcatheter aortic valve implantation (TAVI). Fortunately, these complications can often be successfully treated with a transcatheter valve-in-valve (VinV) implantation. However, prosthetic leaflet dysfunction or immobility from the VinV configuration can lead to severe central aortic insufficiency. We report the first known case of implantation of a third SAPIEN prosthesis (Edwards Lifesciences, Irvine, CA) during TAVI as a valuable bailout strategy to deal with severe aortic insufficiency after VinV implantation.

Comparative Study
Perventricular device closure of doubly committed subarterial ventral septal defect through left anterior minithoracotomy on beating hearts.
Surgical repair of doubly committed subarterial ventricular septal defect (VSD) under cardiopulmonary bypass has been the gold standard with full median sternotomy, complicated by skin scarring and potential mortalities and morbidities from cardiopulmonary bypass. Perventricular device closure of muscular and then perimembranous VSD on beating heats with a small subxiphoid or inferior sternotomy has been attempted in the past few years with good results. We have tried perventricular closure of doubly committed subarterial VSD through a left anterior minithoracotomy as an alternative procedure with a modified occluder. ⋯ Selected doubly committed subarterial VSD can be safely closed with a proper occluder through left anterior minithoracotomy. The Cosmetic results are highly satisfactory.

Comparative Study
Should patients 60 years and older undergo bridge to transplantation with continuous-flow left ventricular assist devices?
Although left ventricular assist devices (LVADs) are now commonly used as a bridge to orthotopic heart transplantation (OHT), the upper patient age limit for this therapy has not been defined. Smaller studies have suggested that advanced age should not be a contraindication to bridge to transplantation (BTT) LVAD placement. The purpose of this study was to examine outcomes in patients 60 years and older undergoing BTT with continuous-flow LVADs. ⋯ This study represents the largest modern cohort in which survival after OHT has been evaluated in patients 60 years or older who received BTT. Older patients have lower short-term survival after OHT when BTT is carried out with a continuous-flow LVAD compared with inotropic agents or direct transplantation.

Multicenter Study Comparative Study
Major infection after pediatric cardiac surgery: external validation of risk estimation model.
A multivariable risk estimation model, in which the primary outcome was major infection, was recently developed and published using The Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database. We have applied this risk estimation model to our congenital heart surgery program over a 16-year time interval to validate this risk estimation model and verify its specific risk factors for major infection. ⋯ Our external validation study confirmed that the STS model can be used as a preoperative risk stratification tool for major infection risk at the single institutional level.
