BACKGROUND: Early detection of acute kidney injury (AKI) after cardiac surgery has improved recently with the discovery and validation of novel urinary biomarkers. However, objective tools to predict the risk of AKI before the insult are still missing. We tested the hypothesis that pre-operative serum fibroblast growth factor 23 (FGF23) concentrations would be elevated in children who develop AKI after heart surgery with cardiopulmonary bypass (CPB). We also compared post-operative FGF23 concentrations to other biomarkers for early detection of AKI...

BACKGROUND: Status in terms of major vascular structure invasion is a crucial factor for successful major hepatic resection. In particular, surgery for advanced tumors with inferior vena cava (IVC) invasion is difficult and may even be dangerous for the patient, having high risk of massive bleeding and greater chance of embolic complications such as stroke, bowel ischemia, and pulmonary venous thrombosis. For such reasons, many surgeons hesitate to carry out such surgical resection, and even if they do so, may not totally remove the tumor including the part inside the IVC, achieving R1 resection...

Background: Perinatal and perioperative brain injury is a fundamental problem in infants with severe congenital heart disease undergoing neonatal cardiac surgery with cardiopulmonary bypass. An impaired neuromotor and neurocognitive development is encountered and associated with a reduction in quality of life. New neuroprotective drugs during surgery are described to reduce brain injury and improve neurodevelopmental outcome. Therefore, our aim was to provide a systematic review and best-evidence synthesis on the effects of neuroprotective drugs on brain injury and neurodevelopmental outcome in congenital heart disease infants requiring cardiac surgery with cardiopulmonary bypass...

Inherited disorders of lipid metabolism may cause a heavy burden of cardiovascular disease early in life. Familial hypercholesterolaemia (FH) with abnormalities of LDL metabolism results in marked LDL elevations and accelerated, multivessel atherosclerosis presenting in teenage or young adulthood. We describe the case of a 33-year-old woman who presented with exertional angina in the setting of pregnancy who was found post-partum to have severe triple-vessel disease including left main disease on coronary angiography (Figs...

It is estimated that 15% of traffic accidents cause trauma to large vessels. In about 70%-95% of cases, aortic rupture took place in the distal ligament of the left subclavian artery, whereas in the remaining cases rupture occurred in the ascending aorta above the aortic valve. Trauma to the aortic sinus and coronary arteries is rarely found in traffic accident victims. Therefore, coronary artery trauma is often misdiagnosed as coronary atherosclerotic heart disease. The present case is a 42 years old male who survived from a traffic accident...

BACKGROUND: Neonates undergoing cardiopulmonary bypass (CPB) are at risk for excessive bleeding. Blood is anticoagulated with heparin during CPB. Heparin activity is reversed with protamine at the end of CPB. Paradoxically, protamine also inhibits blood coagulation when it is dosed in excess of heparin. OBJECTIVES: To evaluate heparin-protamine balance in neonates undergoing CPB using research and clinical assays and determine their association with post-operative bleeding...

PURPOSE OF REVIEW: Since the selection of the first thrombin-binding aptamer in 1992, the use of nucleic acid aptamers to target specific coagulation factors has emerged as a valuable approach for generating novel anticoagulant and procoagulant therapeutics. Herein, we highlight the most recent discoveries involving application of aptamers for those purposes. RECENT FINDINGS: Learning from the successes and pitfalls of the FIXa-targeting aptamer pegnivacogin in preclinical and clinical studies, the latest efforts to develop antidote-controllable anticoagulation strategies for cardiopulmonary bypass that avoid unfractionated heparin involve potentiation of the exosite-binding factor X (FX)a aptamer 11F7t by combination with either a small molecule FXa catalytic site inhibitor or a thrombin aptamer...

Manual palpation of pulses is unreliable in detecting pulsatile flow in human participants, complicating the assessment of return of spontaneous circulation after cardiac arrest. Ultrasound may offer an alternative. This study's objective was to investigate whether return of pulsatile flow in humans can be reliably assessed by common carotid artery ultrasound. We conducted a single-blinded randomised study of common carotid artery ultrasound using 20 cardiopulmonary bypass patients to model the return of pulsatile flow...

We present the case of a 64-year-old man with Mycobacterium chimaera prosthetic aortic valve endocarditis likely acquired through exposure to a contaminated heater-cooler device used for cardiopulmonary bypass during valve replacement. This case demonstrates multi-system involvement with a non-tuberculous mycobacterial species that was previously not considered a significant human pathogen. We review the key features of the case and review published literature regarding an international outbreak of M. chimaera arising from point-source contamination during the manufacturing process...

Some primary and secondary liver carcinomas cannot be resected using a conventional approach due to their size, location, or major vascular invasion. The aim of this study was to explore the application of ex vivo liver resection and autotransplantation for complicated HB in children. A 1.5-year-old girl with HB after repeated chemotherapy was analyzed. In this patient, tumor invasion includes the IV, V, and VIII liver segments, and thrombosis formed in the inferior vena cava and right atrium. It is difficult to obtain complete tumor resection using conventional hepatectomy...

In transposition of the great arteries (TGA), certain coronary patterns have been associated with major adverse events early after the arterial switch operation (ASO). We sought to determine the impact of preoperative echocardiographic (ECHO) diagnosis on the intra- and postoperative morbidity. All patients with TGA born between June 2001 and June 2017 and who underwent ASO were reviewed. Data on presumed coronary anatomy (CA) preoperatively were obtained from the preoperative ECHO report. Intraoperative CA was categorized according to Yacoub classification...

Background: Neuroprotection studies are generally unable to demonstrate efficacy in humans. Our specific hypothesis is that multiple pathophysiologic pathways, of variable importance, contribute to ischemic brain damage. As a corollary to this, we discuss the broad hypothesis that a multifaceted approach will improve the probability of efficacious neuroprotection. But to properly test this hypothesis the nature and importance of the multiple contributing pathways needs elucidation. Our aim is to demonstrate, using functional genomics, in human cardiac surgery procedures associated with cerebral ischemia, that the pathogenesis of perioperative human ischemic brain damage involves the function of multiple variably weighted proteins involving several pathways...
