Outcomes after hospital discharge in children requiring post-cardiotomy extracorporeal membrane oxygenation: a binational retrospective cohort study.

Objectives: To describe longer-term survival and morbidity outcomes after hospital discharge in a binational cohort of children who required extracorporeal membrane oxygenation after cardiac surgery.

Methods: Retrospective cohort study from the Australia and New Zealand Congenital Outcomes Registry for Surgery database. All patients younger than 18 years of age (n=12,290) undergoing paediatric cardiac surgical procedures between 1 January 2013 and 31 December 2021 who required post-cardiotomy extracorporeal membrane oxygenation in the same admission were included.

Early outcomes after post-cardiotomy extracorporeal membrane oxygenation in paediatric patients: a contemporary, binational cohort study.

Objectives: The aim of this study was to assess the early outcomes and risk factors of paediatric patients requiring extracorporeal membrane oxygenation after cardiac surgery (post-cardiotomy).

Methods: Retrospective binational cohort study from the Australia and New Zealand Congenital Outcomes Registry for Surgery database. All patients younger than 18 years of age who underwent a paediatric cardiac surgical procedure from 1 January 2013 to 31 December 2021 and required post-cardiotomy extracorporeal membrane oxygenation (PC-ECMO) in the same hospital admission were included in the study.

Long-term outcomes of hypoplastic left heart syndrome with analysis of the Norwood procedure in infants following bilateral pulmonary artery banding.

Objective: To investigate the early and long-term outcomes of the deferred Norwood procedure by bilateral pulmonary artery banding (BPAB) versus the neonatal Norwood procedure.

Methods: This retrospective study examined 46 patients with hypoplastic left heart syndrome and its variants undergoing the Norwood procedure for single ventricle physiology between 2004 and 2022 at 3 institutions. The patients were divided into 2 groups: neonatal Norwood procedure (group N; n = 23) and staged Norwood procedure in infants following BPAB (group I; n = 23).

Monitoring of intraoperative femoral oxygenation predicts acute kidney injury after pediatric cardiac surgery.

Cardiopulmonary bypass-associated acute kidney injury (CPB-AKI) is a pediatric cardiac surgery postoperative complication that is associated with a longer duration of mechanical ventilation and length of hospital stay. Identifying an early predictor of CPB-AKI is critical. Near infrared spectroscopy (NIRS), which can provide real-time monitoring of regional tissue oxygen saturation (rSO) during CPB, may predict CPB-AKI in an early phase of surgical treatment.

Daily transient discontinuation of extracorporeal LVAD to prevent thromboembolism of mechanical aortic valve prosthesis.

Patients with mechanical aortic valves are generally contraindicated for left ventricular assist device (LVAD) insertion because the prosthetic valve often becomes fixed in closed position. A 41-year-old woman with mechanical aortic valve prosthesis experienced sudden chest pain and developed cardiogenic shock. A paracorporeal pulsatile LVAD and a monopivot centrifugal pump as a right VAD (RVAD) were implanted.

Norwood Procedure Performed on a Patient With Trisomy 13.

Trisomy 13 is associated with a variety of congenital anomalies, some of which are life-threatening and related to poor prognosis. Therefore, cardiac surgery is rarely offered to these patients, especially to those with complex cardiac anomalies. We report the case of a neonate weighing 2324 g who was born with severe congenital heart defects.

[Outcomes of the surgical treatment of infectious endocarditis in a single institute for 13-years].

Recently, due to the progress in patient managements with antibiotics, the prognosis of the active phase infectious endocarditis (IE) has improved, but in some cases, urgent or emergent surgical treatment is inevitable because of the uncontrollable acute heart failure due to valve regurgitation, uncontrollable infection with circulatory collapse, or high embolization risk. We reviewed the outcomes of the 57 IE patients who underwent surgical treatment in our hospital from January, 2000 to April, 2012. Preoperative state including inflammatory responses, bacterial blood culture, antibiotic administration, and surgical procedures were examined.

Aortic arch rerouting and OPCAB in a patient with situs inversus totalis.

Endovascular therapy approaches for aortic aneurysm have lowered the mortality and morbidity rates even in high-risk patients; moreover, these approaches are applied in the management of aortic arch pathologies by transposition of the supra-aortic branches. We present the case of a 75-year-old female patient with situs inversus totalis on hemodialysis. The patient underwent off-pump aortic arch rerouting and thoracic endovascular aortic repair concomitant with coronary artery bypass grafting for distal aortic arch aneurysm and ischemic heart disease.

Five-week use of a monopivot centrifugal blood pump as a right ventricular assist device in severe dilated cardiomyopathy.

Right heart failure is a critical complication in patients requiring mechanical ventricular support. However, it is often difficult to provide adequate right ventricular support in the acute phase. A 41-year-old woman diagnosed with dilated cardiomyopathy with severe right heart failure underwent implantation of a paracorporeal pulsatile left ventricular assist device (LVAD, Nipro Corporation, Tokyo, Japan) and a MERA monopivot centrifugal pump (Senko Medical Instrument Manufacturing Co.

Moderate prosthesis-patient mismatch may be negligible in elderly patients undergoing conventional aortic valve replacement for aortic stenosis.

Together with aging of the Japanese population, aortic valve replacement (AVR) for aortic stenosis (AS) is now becoming more and more common in the elderly. When the aortic annulus is too small to allow an adequate sized prosthetic valve, aortic root enlargement is required to avoid prosthesis-patient mismatch (PPM). However, age-related comorbidities including aortic root calcification bring significant risk in performing aortic root enlargement.
