Comparative StudySerum cardiac troponin-I elevation in neonatal cardiac surgery is lesion-dependent.
Serum cardiac troponin-I (cTn-I) is a marker for myocardial injury in adults that undergoes developmental isoform change. To determine its utility as a myocardial injury marker in neonates, the authors examined the perioperative pattern of cTn-I elevation in neonates undergoing surgical repair for hypoplastic left-heart syndrome (HLHS) and transposition of great arteries (TGA). ⋯ It was found that perioperative elevations in serum cTn-I in neonates with TGA and HLHS were influenced by duration of aortic cross-clamp application, CPB, and the presence of VSD.

Comparative StudyOff-pump coronary artery bypass attenuates transient hepatocellular damage after myocardial revascularization.
Cardiopulmonary bypass (CPB) affects hepatocellular integrity and occasionally results in liver dysfunction after cardiac surgery. Performing coronary artery bypass graft surgery without CPB may help to reduce the risk of this complication and better preserve perioperative liver function. This study compared perioperative hepatocellular damage in patients undergoing on-pump and off-pump bypass surgery. ⋯ CPB induced transient subclinical hepatocellular damage, whereas off-pump revascularization attenuated this damage.

Comparative StudyMajor clinical outcomes in adults undergoing thoracic aortic surgery requiring deep hypothermic circulatory arrest: quantification of organ-based perioperative outcome and detection of opportunities for perioperative intervention.
The purpose of this study was to describe clinical outcome after adult thoracic aortic surgery requiring standardized deep hypothermic circulatory arrest (DHCA), to determine mortality and length of stay, neurologic outcome, cardiorespiratory outcome, and hemostatic and renal outcome after DHCA. ⋯ The protocol for DHCA at the authors' institution is associated with superior or equivalent perioperative outcomes to those reported in the literature. This study identified the need for further quantification of the clinical outcomes after DHCA in order to prioritize outcome-based hypothesis-driven prospective intervention in DHCA.
