Case ReportsEarly percutaneous valve failure within bioprosthetic tricuspid tissue valve replacements.
To describe the cases of percutaneous valve failure following implantation of the Medtronic Melody™ and the Edwards Sapien™ valve in the tricuspid position. ⋯ Transcatheter placement of percutaneous valves in the tricuspid position is technically a relatively straightforward procedure but early valve failure raises some concerns about the viability of the valve in this position, at least in some patients.

Observational StudyPercutaneous revascularization improves outcomes in patients with prior coronary artery bypass surgery.
Although ACC/AHA guidelines recommend a low threshold for catheterization after coronary artery bypass surgery (CABG), in clinical practice repeat revascularization often appears unfeasible and data on outcomes are scarce. ⋯ Significantly fewer post-CABG patients received repeat revascularization than all-comers however; PCI was associated with improved mortality in both the diabetic and the nondiabetic patient population. These findings support the practice of attempting revascularization in post-CABG patients, particularly in those with an ACS.

Prevalence of and risk factors for acute occlusive arterial injury following pediatric cardiac catheterization: a large single-center cohort study.
To describe the prevalence of and identify risk factors for acute occlusive arterial injury (AOAI) in a large volume pediatric cardiac catheterization laboratory. ⋯ AOAI occurred in 4.3% of pediatric cardiac catheterizations, and was most likely in smaller children and those with larger arterial catheters. Risk was also independently increased by arterial catheter exchange and having a final ACT <250 sec. These data act as an important benchmark and identify areas for intervention for future studies.

Hybrid perventricular device closure of doubly committed subarterial ventricular septal defects: mid-term results.
Doubly committed Subarterial ventricular septal defect (VSD) is a specific anatomic type of VSD located just beneath the aortic valve. The purpose of this study was to evaluate the safety and feasibility of using minimal invasive perventricular device closure in managing this type of VSD. ⋯ Perventricular closure of doubly committed subarterial VSDs appears to be a safe and effective minimally invasive technique with good mid-term outcomes.

Case ReportsStent exteriorization facilitates surgical repair for large-bore sheath complications.
Endovascular therapy for peripheral vascular and valvular disease has rapidly expanded and yet also produced new challenges for vascular access and closure. Current generation thoracic endograft (TEVAR) outer diameter sheath sizes range from 18 to 25 French, and the options for vascular access closure include off-label use of a closure device versus surgical cutdown. We describe a patient with a complex, post-dissection, descending aortic aneurysm who required TEVAR and had a vascular access complication repaired with stent exteriorization with open repair.
