Comparative StudyNeutrophil gelatinase-associated lipocalin levels after use of mini-cardiopulmonary bypass system.
Neutrophil gelatinase-associated lipocalin (NGAL) has been implicated as an early predictive urinary biomarker of ischemic acute kidney injury (AKI). The aim of this study was to compare the effects of miniaturized cardiopulmonary bypass system (MCPB) vs. standard cardiopulmonary bypass system (SCPB) system on kidney tissue in patients undergoing myocardial revascularization using urinary NGAL levels as an early marker for renal injury. Sixty consecutive patients who underwent myocardial revascularization were studied prospectively. ⋯ The MCPB system is safe in routine clinical use. Kidney function is better protected during MCPB as demonstrated by NGAL levels. NGAL represents an early biomarker of renal failure in patients undergoing cardiac surgery and the valuation of its concentration can aid in medical decision-making.

Comparative StudyAge >or=75 years is associated with greater resource utilization following coronary artery bypass grafting.
We examined whether complication rates and resource utilization among elderly patients undergoing coronary artery bypass grafting (CABG) differed from their younger counterparts. A retrospective review of prospectively collected data was conducted of 2936 patients undergoing first-time isolated CABG. Demographic and baseline clinical characteristics were collected, and patients grouped according to age into those <75 years (n=2424, younger) and >or=75 years (n=512, older). ⋯ Older patients incurred longer intensive care stays (2 days interquartile range (IQR) [1-3] vs. 1 day IQR [1-2]; P<0.0001) and a longer postoperative stay (8 days IQR [6-11] vs. 6 days IQR [5-8]; P<0.0001). Multivariate logistic regression analysis showed age >or=75 years was an independent predictor of postoperative LOS (OR=1.23, 95% CI [0.49-1.96]; P=0.001). Older patients aged >or=75 years undergoing CABG had significantly higher rates of postoperative complications and greater resource utilization than their younger counterparts.

Case ReportsHeartmate XVE destination therapy for end-stage heart failure in a patient with human immunodeficiency virus.
Cardiac dysfunction is a known predictor of survival in patients with acquired immunodeficiency syndrome. In this report, we describe a human immunodeficiency virus (HIV)-infected patient with worsening heart failure who was managed successfully for 16 months with placement of a left ventricular assist device.

We report our experience with repair of a variety of congenital heart defects utilizing a ministernotomy incision. A ministernotomy was used in 79 patients with a variety of congenital heart diseases from November 2004 to August 2007. Patients included 36 males and 43 females with ages ranging from 1 month to 122 months (median age, 22 months). ⋯ The intensive care unit (ICU) stay ranged from 1 to 21 days (median ICU stay, 1 day) and the hospital stay ranged from 2 to 56 days (median hospital stay, 4 days). There were no reinterventions for residual cardiac defects. We demonstrate the safety and efficacy of ministernotomy for the correction of a range of congenital heart defects with improved cosmetic results.

Primary sternal plating to prevent sternal wound complications after cardiac surgery: early experience and patterns of failure.
Sternal closure with rigid titanium plates (primary sternal plating) may reduce sternal wound complications in high-risk patients. We began performing primary sternal plating for the following indications: obesity, manual laborer, osteoporotic sternum, or intraoperative transverse sternal fracture. Patients receiving plate closure were compared to a risk-matched control group receiving wire closure. ⋯ No early sternal wound complications occurred in the plate group, compared to 12 (12%) in the wire group (P=0.067). The incidence of late sternal wound complications was 10% in both groups (P=1.0). Primary sternal plating appears to provide benefits over wire closure during the early postoperative period, but may not prevent late wound complications in patients with osteoporosis or extreme obesity.
