OBJECTIVE: Because of advances in technology and experience of the operator, endovascular aneurysm repair (EVAR) has supplanted open repair to treat abdominal aortic aneurysm (AAA). The low 30-day mortality and morbidity of EVAR make the endovascular approach particularly suitable for patients at high surgical risk. However, endoleak or endograft migration requiring secondary intervention or open surgical conversion is a limitation of EVAR. The Nellix system (Endologix, Inc, Irvine, Calif) has been designed to seal the entire AAA to overcome these limitations with EVAR...

OBJECTIVE: Hostile proximal aortic neck (HN) challenges the suitability for standard endovascular aneurysm repair (EVAR) of patients at high risk for "open" repair. However, there has been little if any focus placed on the individual role of the "nonlength" HN features in EVAR outcomes. The aim of this study was to evaluate their individual and potentially predictive role in outcomes of EVAR under HN conditions. METHODS: Data of 156 consecutive EVAR patients with short (<15 mm) HN, treated with the Endurant device (Medtronic Cardiovascular, Santa Rosa, Calif) at three European academic vascular centers between 2007 and 2015, were collected and retrospectively analyzed...

OBJECTIVES: Percutaneous mitral repair with the MitraClip system (Abbott Vascular, Santa Clara, Calif) has been available in trials since 2006 and is currently approved for patients with degenerative mitral valve disease at prohibitive risk for surgery. There has been concern that novel transcatheter approaches may detract from mitral valve surgical volumes. We sought to evaluate the influence of our MitraClip program on our surgical mitral valve volumes and outcomes. METHODS: All patients referred for MitraClip underwent evaluation by a multidisciplinary team...

OBJECTIVE: With more than a decade of use of endovascular aneurysm repair (EVAR), we expect to see a rise in the number of failing endografts. We review a single-center experience with EVAR explants to identify patterns of presentation and understand operative outcomes that may alter clinical management. METHODS: A retrospective analysis of EVARs requiring late explants, >1 month after implant, was performed. Patient demographics, type of graft, duration of implant, reason for removal, operative technique, length of stay, complications, and in-hospital and late mortality were reviewed...
