Even mild paravalvular leakage (PVL) after transcatheter aortic valve replacement (TAVR) is associated with increased late mortality. Electrocardiogram-gated multi-slice computed tomography (MSCT) enables detailed aortic annulus assessment. We describe the impact of MSCT for PVL following TAVR. ⋯ The OSACA ratio has a significantly higher discriminatory performance for PVL ≤ trace than the OSACA (TEE) ratio, and aortic annular measurement from MSCT is more accurate than that from TEE.

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.

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.

Case Reports
Successful single-stage repair of an interrupted aortic arch with a bicuspid aortic valve in a young adult.
Interrupted aortic arch is a rare congenital malformation. We describe the case of an interrupted aortic arch with a bicuspid aortic valve and severe aortic stenosis. The patient underwent a single-stage aortic valve replacement (AVR) and ventral aorta repair through a median sternotomy-laparotomy.
