Vascular laceration is a rare but potentially fatal complication with excimer laser-assisted pacemaker or implantable cardioverter-defibrillator lead extraction. We report our experience on management of vascular laceration during laser-assisted lead extraction. ⋯ Cardiopulmonary bypass standby is helpful when performing laser-assisted lead extraction to treat potentially fatal vascular laceration. Dual-coil lead is an independent risk factor to predict intraoperative vascular laceration.

Differential release kinetics of cardiac biomarkers including brain natriuretic peptide (BNP), Troponin-I, and CK-MB following valve replacement (VR) are not well characterized. ⋯ Release kinetics of cardiac biomarkers is significantly different following VR; BNP levels increase following an initial transient decline. Only BNP was a predictor of postoperative variables.

The aim of this study is to evaluate acute kidney injury (AKI) after total aortic arch repair (TAR) with moderate hypothermic circulatory arrest (MHCA) and selective antegrade cerebral perfusion (SACP). ⋯ Postoperative AKI stratified by RIFLE criteria was significantly associated with short- and mid-term outcomes in TAR with MHCA and SACP.

To compare cardiopulmonary exercise capacity of patients undergoing primary total cavopulmonary connection (TCPC) with those undergoing TCPC after a prior bidirectional Glenn (BDG). ⋯ There were no differences in the exercise parameters of patients undergoing a staged versus a primary TCPC, fenestrated versus nonfenestrated TCPC, and age at surgery less than or more than 7 years. Exercise parameters were better in the extracardiac conduit group versus lateral tunnel TCPC groups. Patients who had a TCPC after prior interruption of APBF had better exercise parameters.

Extracorporeal membrane oxygenation can be done through several cannulation sites. Axillary artery cannulation is commonly performed through a Dacron graft sutured in an end-to-side fashion to the axillary artery. Direct cannulation of the axillary artery appears a reliable technique with low rate of complications. We report our experience in 16 patients using the direct cannulation technique.
