Long-term follow-up after aortic valve replacement with Edwards Prima Plus stentless bioprostheses in patients younger than 60 years of age.
The Edwards Prima Plus was one of the first stentless aortic valve bioprostheses, with larger orifice areas and improved hemodynamics compared to stented bioprostheses. The aim of the present single-center retrospective study was to assess the long-term results of the Edwards Prima Plus in patients 60 years old or younger. ⋯ In patients aged 60 years or younger, an Edwards Prima Plus can provide reliable long-term results with acceptable freedom-from-reoperation rates.

Endovascular coil embolization of segmental arteries prevents paraplegia after subsequent thoracoabdominal aneurysm repair: an experimental model.
To test a strategy for minimizing ischemic spinal cord injury after extensive thoracoabdominal aneurysm (TAAA) repair, we occluded a small number of segmental arteries (SAs) endovascularly 1 week before simulated aneurysm repair in an experimental model. ⋯ Endovascular coiling of 2 to 4 SAs prevented paraplegia in an experimental model of extensive hybrid TAAA repair, and helped protect the spinal cord from ischemic histopathologic injury. A clinical trial in a selected patient population at high risk for postoperative spinal cord injury may be appropriate.

Observational StudyResidual lesions in postoperative pediatric cardiac surgery patients receiving extracorporeal membrane oxygenation support.
The objective of this study was to examine the incidence and clinical outcomes of residual lesions in postoperative pediatric cardiac surgery patients receiving extracorporeal membrane oxygenation (ECMO) support. ⋯ Residual lesions are present in approximately one-quarter of postoperative cardiac surgery patients requiring ECMO support. All postoperative pediatric cardiac surgery patients unable to be weaned off ECMO successfully should be evaluated actively for residual lesions, preferably by cardiac catheterization imaging. Earlier detection of residual lesions and reintervention are associated with improved clinical outcome.

Early single-center experience in sutureless aortic valve implantation in 120 patients.
The study objective was to evaluate the safety and efficacy of sutureless self-expanding nitinol stent-frame aortic valve prostheses made of equine pericardium implanted in patients with symptomatic aortic valve disease. ⋯ In this large single-center experience with sutureless aortic valve replacement, the surgical procedure is shown to be safe and time-saving. In view of the excellent hemodynamic results and shortening of aortic crossclamp and bypass times, we notice advantages especially in high-risk patients. Minimally invasive access seems to be facilitated. The long-term durability of this prosthesis has yet to be determined.
