Case ReportsOne-stage definitive repair of complete atrioventricular septal defect and pulmonary atresia with major aortopulmonary collateral arteries.
Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries is considered the most severe end of the tetralogy of Fallot spectrum, whereas complete atrioventricular septal defect associated with tetralogy of Fallot is a rare congenital defect. However, the combination of pulmonary atresia, major aortopulmonary collateral artery and complete atrioventricular septal defect is extremely rare, and surgical repair has not been reported. We describe a successful, 1-stage correction in a 7-month-old boy with this condition, who had an additional complication of a single aortic outlet from the right ventricle and significant atrioventricular valve regurgitation.

Impact of initial aortic diameter and false-lumen area ratio on Type B aortic dissection prognosis.
Medical treatment is the gold standard for uncomplicated acute Type B aortic dissection (ATBAD). Although endovascular treatment could become an alternative therapy, it is unclear which ATBAD patients should undergo endovascular intervention. We aimed to evaluate the outcomes of patients with uncomplicated ATBAD and identify the risk factors for major adverse events. ⋯ UMIN 000025388, https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000029229.

Cold-inducible ribonucleic acid-binding protein attenuates acute kidney injuries after deep hypothermic circulatory arrest in rats.
Cold-inducible ribonucleic acid-binding protein (CIRP) has been identified to play a role in the antiapoptotic effect of hypothermia. We sought to investigate the renoprotection of CIRP in a rat model of deep hypothermic circulatory arrest. ⋯ Our findings suggest that the CIRP exerts a robust renoprotective effect by inhibiting apoptosis in the rat model of deep hypothermic circulatory arrest.

Controlled flow diversion in hybrid venoarterial-venous extracorporeal membrane oxygenation.
Patients on venoarterial or venovenous extracorporeal membrane oxygenation (ECMO) support may require venoarterial-venous (VAV-ECMO) configuration during follow-up. We report 12 cases of VAV-ECMO with significant outflow steal. ⋯ Non-invasive monitoring of flow rates within the supplying cannulae of VAV-ECMO and the use of partial occlusion for venous-supplying cannula enable individualized patient management and effective weaning from VAV-ECMO.

Case ReportsPercutaneous left atrial unloading to prevent pulmonary oedema and to facilitate ventricular recovery under extracorporeal membrane oxygenation therapy.
Left-sided unloading during extracorporeal membrane oxygenation (ECMO) therapy is crucial to prevent pulmonary oedema and facilitate ventricular recovery. We present the case of a 55-year-old man under ECMO therapy with pre-existing left ventricular (LV) thrombus formation and in need of ventricular unloading. ⋯ Percutaneous trans-septal insertion of a TandemHeart cannula incorporated in an ECMO circuit for the prevention of pulmonary oedema and subsequent weaning from extracorporeal circulation was feasible and safe in a patient with cardiogenic shock and an LV thrombus.
