Multicenter StudySuture technique does not affect hemodynamic performance of the small supra-annular Trifecta bioprosthesis.
The study objective was to evaluate whether aortic valve replacement with the Trifecta valve (St Jude Medical Inc, St Paul, Minn) using simple sutures produces better hemodynamic performance than valve replacement with noneverting pledget-reinforced sutures. ⋯ The suture method did not affect hemodynamic performance of supra-annular bioprostheses in patients with small aortic annulus sizes. Choice of suture technique should be determined by surgeon experience and local anatomic features.

Multicenter StudySpinal cord ischemia after simultaneous and sequential treatment of multilevel aortic disease.
The aim of the present study is to report a risk analysis for spinal cord injury in a recent cohort of patients with simultaneous and sequential treatment of multilevel aortic disease. ⋯ In our experience, the risk of spinal cord injury is still substantial at 8% in patients with multilevel aortic disease. The distance of the distal landing zone from the celiac trunk is a significant predictor of spinal cord ischemia.

High basal level of autophagy in high-altitude residents attenuates myocardial ischemia-reperfusion injury.
Hypoxia can induce autophagy, which plays an important role in cardioprotection. The present study tested the hypothesis that patients with congenital heart disease living at a high altitude could resist ischemia-reperfusion injury better than those at a low altitude, through elevated basal autophagy by chronic hypoxia. ⋯ Patients living at a high altitude with congenital heart disease resisted ischemia-reperfusion injury during cardiac surgery better than those at a low altitude, possibly through elevated basal autophagy induced by chronic hypoxia.

Multicenter StudyEffect of feeding modality on interstage growth after stage I palliation: a report from the National Pediatric Cardiology Quality Improvement Collaborative.
Achieving adequate growth after stage 1 palliation for children with single-ventricle heart defects often requires supplemental nutrition through enteral tubes. Significant practice variability exists between centers in the choice of feeding tube. The impact of feeding modality on the growth of patients with a single ventricle after stage 1 palliation was examined using the multiinstitutional National Pediatric Cardiology Quality Improvement Collaborative data registry. ⋯ In this large multicenter cohort, interstage growth improved for all groups and did not differ by feeding modality. With appropriate caloric goals and interstage monitoring, adequate growth may be achieved regardless of feeding modality and therefore local comfort and complication risk should dictate feeding modality.
