ReviewTAVR Procedural Volumes and Patient Outcomes: Analysis of Recent Data.
In less than 15 years, transcatheter aortic valve replacement (TAVR) has progressed from a procedure of last resort in patients at prohibitively high perioperative risk for major morbidity and mortality from surgical valve replacement to a viable alternative option to surgery in most patients with native (non-bicuspid) aortic valve stenosis. The number of medical centers offering TAVR has rapidly proliferated. There is mounting evidence that there are variations in patient outcomes associated with the yearly number of TAVR cases performed at each respective center. This review outlines the evolution of TAVR indications, common complications, the current literature addressing the association between procedural volumes and patient outcomes in TAVR, and offers a synopsis of risk factor assessment for patients considered for TAVR.

ReviewA Narrative Review of Analytics in Pediatric Cardiac Anesthesia and Critical Care Medicine.
Congenital heart disease (CHD) is one of the most common birth anomalies, and the care of children with CHD has improved over the past 4 decades. However, children with CHD who undergo general anesthesia remain at increased risk for morbidity and mortality. The proliferation of electronic health record systems and sophisticated patient monitors affords the opportunity to capture and analyze large amounts of CHD patient data, and the application of novel, effective analytics methods to these data can enable clinicians to enhance their care of pediatric CHD patients. This narrative review covers recent efforts to leverage analytics in pediatric cardiac anesthesia and critical care to improve the care of children with CHD.

ReviewNear-Infrared Spectroscopy in Pediatric Congenital Heart Disease.
Near-infrared spectroscopy (NIRS) is widely used to monitor tissue oxygenation in the pediatric cardiac surgical population. Clinicians who use NIRS must understand the underlying measurement principles in order to interpret and use this monitoring modality appropriately. The aims of this narrative review are to provide a brief overview of NIRS technology, discuss the normative and critical values of cerebral and somatic tissue oxygen saturation and the interpretation of these values, present the clinical studies (and their limitations) of NIRS as a perioperative monitoring modality in the pediatric congenital heart disease population, and introduce the emerging and future applications of NIRS.

ReviewThe Use of Umbilical Cord Blood for Autologous Transfusion in Neonatal Open Heart Surgery.
In the last few decades, the use of umbilical cord blood (UCB) has received increasing attention, not only as a source of stem cells, but also as a transfusion product for the treatment of anemia in the neonatal and even the adult population. This review focuses on data reports and collection efforts related to the autologous transfusion of UCB in full-term neonates with prenatally diagnosed critical congenital heart defects. This review summarizes different aspects of UCB transfusion, including indications and contraindications; the collection procedure; storage timing; and special properties of one of its constituents, fetal hemoglobin, in the setting of hypothermic cardiopulmonary bypass.

Measuring Cerebral Carbon Dioxide Reactivity With Transcranial Doppler and Near-Infrared Spectroscopy in Children With Ventricular Septal Defect.
Neurologic impairment is frequently observed in children with congenital heart disease. Impairment in cerebrovascular carbon dioxide reactivity (CO2R) is related with poor neurologic outcomes. The present study examined CO2R measured with transcranial Doppler (TCD) and near-infrared spectroscopy (NIRS) in children with ventricular septal defect undergoing cardiac surgery. ⋯ During anesthesia, CO2R remains preserved in children with a ventricular septal defect. Even though there is lack of correlation between CO2R-TCD and CO2R-NIRS, changes in TOI and VMCA were correlated as the PETCO2 changed. NIRS may be used as a surrogate to investigate CO2R when the ultrasound window is poor.
