Interest in ultrasound education in medical schools has increased dramatically in recent years as reflected in a marked increase in publications on the topic and growing attendance at international meetings on ultrasound education. In 2006, the University of South Carolina School of Medicine introduced an integrated ultrasound curriculum (iUSC) across all years of medical school. That curriculum has evolved significantly over the 9 years. A review of the curriculum is presented, including curricular content, methods of delivery of the content, student assessment, and program assessment. Lessons learned in implementing and expanding an integrated ultrasound curriculum are also presented as are thoughts on future directions of undergraduate ultrasound education. Ultrasound has proven to be a valuable active learning tool that can serve as a platform for integrating the medical student curriculum across many disciplines and clinical settings. It is also well-suited for a competency-based model of medical education. Students learn ultrasound well and have embraced it as an important component of their education and future practice of medicine. An international consensus conference on ultrasound education is recommended to help define the essential elements of ultrasound education globally to ensure ultrasound is taught and ultimately practiced to its full potential. Ultrasound has the potential to fundamentally change how we teach and practice medicine to the benefit of learners and patients across the globe.Electronic supplementary materialThe online version of this article (doi:10.1186/s13089-015-0035-3) contains supplementary material, which is available to authorized users.

Extant epidemiologic results for pediatric congenital heart disease (CHD) are dated. Given the degree of variability in previous prevalence estimates and the rapid changes in pediatric cardiology diagnostic and treatment procedures, a reexamination of these rates represents a potentially important update in this area of inquiry. This report characterizes the prevalence rates of children with CHD in one state's treated pediatric population by type of lesion and in comparison with published rates from previous studies. Two 15-year data sets (1996-2010) are analyzed. The inclusion criteria for the study required the participants to be 17 years or younger, enrollees in the South Carolina State Medicaid or State Health Plan, and recipients of a CHD diagnosis on one or more service visits to a pediatrician or pediatric cardiologist. A 15-year accrued prevalence rate for pediatric CHD of 16.7 per 1,000 was found among 1,145,364 unduplicated children served. The annual incidence rates varied from 6.3 to 8.6 per 1,000, with an initial downward trend from 1996 to 2002 followed by an upward trend from 2003 to 2008. A higher prevalence of atrioventricular canal/endocardial cushion defects, common/single ventricle, double-outlet right ventricle, tetralogy of Fallot, and truncus arteriosus and a lower prevalence of dextro-transposition of the great arteries were diagnosed in South Carolina than in other states and countries according to published results. The study results underscore the need for periodic updating of prevalence data for pediatric CHD, both in total and for specific lesions, to anticipate and provide more specialized care to young patients with CHD, especially in the more rare and complex cases.
