Comparative StudyEffective radiation dose in computed tomographic angiography of the chest and diagnostic cardiac catheterization in pediatric patients.
Computed tomographic angiography (CTA) and cardiac catheterization are useful adjuncts to echocardiography for delineating cardiovascular anatomy in pediatric patients. These studies require ionizing radiation, and it is paramount to understand the amount of radiation pediatric patients receive when these tests are performed. Modern dosimetry methods facilitate the conversion of radiation doses of varying units into an effective radiation dose. ⋯ The median ED for children <1 year of age in the CTA group was 0.76 mSv compared with 13.4 mSv for the catheterization group (p < 0.0001). Nongated CTA of the chest exposes children to 15 times less radiation than diagnostic cardiac catheterization. Unless hemodynamic data are necessary, CTA of the chest should be considered in lieu of diagnostic cardiac catheterization in patients with known or presumed cardiac disease who need additional imaging beyond echocardiography.

Comparative StudyProspective assessment of novice learners in a simulation-based extracorporeal membrane oxygenation (ECMO) education program.
This study aimed to assess the impact of integrating a simulation-based education module into an extracorporeal membrane oxygenation (ECMO) curriculum on novice learners and to test the duration of time that skills obtained during this training exercise were retained. The authors hypothesized that multidisciplinary, simulation-based ECMO training would improve comfort and confidence levels among participants. An ECMO training curriculum was developed that incorporated in situ simulation modules to train multidisciplinary health care professionals involved in the management of patients receiving ECMO in the pediatric cardiac intensive care unit (PCICU). ⋯ All four questionnaires were completed by 18 participants. Simulation-based training is an effective method of improving knowledge, ability, and confidence levels among novice ECMO specialists and physician trainees. Further research is needed to assess real-time demonstration of skills retention during ECMO emergencies.

Comparative StudySafety advantage of modified minimally invasive cardiac surgery for pediatric patients.
Minimally invasive cardiac surgery (MICS) using a small surgical incision in children provides less physical stress. However, concern about safety due to the small surgical field has been noted. Recently, the authors developed a modified MICS procedure to extend the surgical field. ⋯ According to the indices, modified MICS was similar to traditional open surgery and shorter time or lower bleeding volume than conventional MICS. No major mortality or morbidity occurred. In conclusion, the modified MICS procedure, which requires no special techniques, was as safe as conventional open heart surgery and even reduced perioperative morbidity.

Case ReportsLate manifestation of coarctation of the aorta after arterial switch operation for D-transposition of the great arteries with intact ventricular septum.
We describe an infant with D-transposition of the great arteries with an intact ventricular septum who developed coarctation of the aorta 13 days after arterial switch operation. A mildly hypoplastic aortic isthmus was present on echocardiogram at the time of the arterial switch operation, but there was no echocardiographic or clinical evidence of coarctation of the aorta.

Improving teamwork, confidence, and collaboration among members of a pediatric cardiovascular intensive care unit multidisciplinary team using simulation-based team training.
Findings show that simulation-based team training (SBTT) is effective at increasing teamwork skills. Postpediatric cardiac surgery cardiac arrest (PPCS-CA) is a high-risk clinical situation with high morbidity and mortality. Whereas adult guidelines managing cardiac arrest after cardiac surgery are available, little exists for pediatric cardiac surgery. ⋯ A significant increase (p < 0.05) also was observed in the use of Team STEPPS concepts immediately after training and 3 months later. This study showed SBTT to be effective in improving communication and increasing confidence among members of a multidisciplinary team during crisis scenarios. Thus, SBTT provides an excellent tool for teaching and implementing new processes.
