This article is a review of the highlights of pertinent literature published during the 12 months of 2017, which is of interest to the congenital cardiac anesthesiologist. Following a search of the US National Library of Medicine PubMed database, several topics emerged where significant contributions were made in 2017, and that the authors of this manuscript felt were noteworthy to be summarized in this review: Training in pediatric cardiac anesthesia, the costs of congenital heart disease (CHD), catheter versus surgical intervention for CHD, cerebral oxygen saturation in CHD, and mechanical circulatory support in children. Training in pediatric cardiac anesthesia In 2004, the Accreditation Council for Graduate Medical Education (ACGME) Next Accreditation system was implemented with the creation of milestones to all specialties.(1) Since 2007, for surgeons who operate on patients with CHD ranging from neonates to adults, a subspecialty certification in congenital cardiac surgery is granted following completion of a one-year accredited residency and passing of a written examination and an oral examination.(2) The number of accredited surgical programs in the US has increased from 2 in 2006 to 12, and the number of graduates has increased from 2 in 2008 to 44 in 2014.(3,4) Along with the increase in structured training for congenital cardiac surgery, there has been an increase in the need of physicians with advanced knowledge and experience in pediatric cardiac intensive care. Several informal advanced training pathways have been suggested following surgical, anesthesia or intensive care trainings and were discussed at the 10 th International Conference of the Pediatric Cardiac Intensive Care Society.(5) Similarly to surgical and intensive care specialties, pediatric cardiac anesthesiology has evolved as a subspecialty devoted to patients with CHD ranging from neonates to adults. While there is a consensus on the need to define standards for the pediatric cardiac anesthesia fellowship, there remains a wide variability in duration of training and clinical experience. Different training pathways have been proposed in the past few years and several recent publications are highlighted to outline the proposed future pathways. In Germany, a working group representing the German Society for Anesthesiology and Intensive Care surveyed all pediatric cardiac centers with the intent to define "expertise in pediatric cardiac anesthesia".(6) Twenty-seven centers with an active pediatric cardiac surgery program participated in the survey with a response rate of 96.3%. The suggested length of training in pediatric cardiac anesthesia was 12-months in 42.3% of centers with a mean of 10.8-months to achieve sufficient experience. However, the length of training may not be reflective of the competence of the trainee.(7) Because, different learners with different knowledge or experience backgrounds progress at different rates, the time needed by a trainee to achieve competence may vary.(8,9) Recently, based on the ACGME Milestones Model...
