Seventy-eight per cent describe their career perspectives as promising, and 84% would start a fellowship in pediatric cardiology again. CONCLUSION  The majority of pediatric cardiology fellows and residents are satisfied with their working environment and with their choice of a career in pediatric cardiology. Besides the heavy work load, we identified the urgent desire for better structured transparent clinical training concept including the teaching of manual skills, i.e., invasive procedures and catheterization.

A traction-assisted (TA) strategy has been recently developed for ESD. In this study, we evaluated the safety and efficacy of TA-ESD compared with conventional ESD (C-ESD). METHODS  We searched PubMed, Embase, Web of Science, and the China National Knowledge Infrastructure to identify randomized clinical trials that compared TA-ESD and C-ESD. No filters for language or date of publication were used. Outcomes included complete resection rate, resected specimen size, procedure time, hemostasis usage (frequency), overall complication rate, perforation rate, and delayed bleeding rate. We used the mean difference (MD) for continuous outcomes in a random-effects model and Peto odds ratio (POR) for binary outcomes where any zero cell existed. Effect sizes and their 95 % confidence intervals (CIs) were determined. RESULTS  12 out of 929 identified articles, including 1499 patients, were analyzed. According to pooled results, TA-ESD produced similar R0 resections to C-ESD, but its procedure time (minutes) was shorter than that of C-ESD (MD - 16.02, 95 %CI - 22.71 to - 9.33). Moreover, TA-ESD had a lower complication rate (POR 0.47, 95 %CI 0.29 to 0.76) and perf
