We report on the applicability of intraoperative regional oxygen saturation (rSO2) desaturation score by near-infrared spectroscopy in the early detection of postoperative low output state (LOS) in infants with congenital heart disease who underwent cardiac surgery. ⋯ The intraoperative use of NIRS provided an early warning sign of hemodynamic or metabolic compromise, enabling early and rapid intervention to prevent or reduce the severity of potentially life-threatening complications.

Insertion of an Abiomed Impella® left ventricular assist device following bioprosthetic aortic valve placement.
Post-cardiotomy cardiogenic shock is an infrequent devastating complication with few options for support. ⋯ This is the first published report of successful use of an Impella 5.0 (ABIOMED; Danvers, MA) for post-cardiotomy cardiogenic shock through a new implanted bioprosthetic aortic valve.

Transcatheter aortic valve insertion catastrophe in inoperable patients: should aortic valve replacement be denied?
This paper reports the outcomes of patients initially deemed inoperable for standard aortic valve replacement who received transcatheter aortic valve insertion. Each patient experienced a transcatheter valve insertion complication and was then subsequently reconsidered for urgent standard valve replacement. We review the outcomes of these inoperable patients and discuss recommendations for managing this complication.

This report describes an effective cerebral perfusion method using an additional 4th side limb graft sewn to a trifurcated graft in patients undergoing redo aortic root reconstruction combined with total aortic arch replacement. This method is useful in cases where the origin of the innominate artery is unsuitable for clamping or when axillary perfusion is not employed, and assures continuous brain protection and minimizes circulatory arrest time.
