BackgroundTricuspid annular plane systolic excursion measured by M‐mode (MM‐TAPSE) has been validated as a marker of right ventricular systolic performance. A similar measurement by 2D imaging (2D‐TAPSE) can be obtained. We sought to determine the correlation and strength of agreement between MM‐TAPSE and 2D‐TAPSE in children.MethodsEchocardiographic studies performed for clinical indications were reviewed retrospectively. All consecutive subjects ≤18 years of age were included. The cohort was divided into those with normal echocardiographic findings and those with disorders affecting the right ventricle. Digitally recorded images were analyzed for both MM‐TAPSE and 2D‐TAPSE. Measurements of 2D‐TAPSE were made in an apical four‐chamber view, from the tricuspid valve annulus to a consistent point at the apex of the imaging sector at end‐diastole and end‐systole, with the difference representing the 2D‐TAPSE value.ResultsA total of 329 subjects (mean age 9.0 ± 6.1 years) met entry criteria. Correlation coefficient between MM‐TAPSE and 2D‐TAPSE was 0.90. Bland–Altman analysis showed agreement between the two methods to be within 1.2 ± 2.6 mm (mean percentage difference of 6.5%). About 1 mm difference between MM‐TAPSE and 2D‐TAPSE was consistently observed in all diagnostic subgroups, and across all age categories.ConclusionMM‐TAPSE and 2D‐TAPSE correlate strongly, with 2D‐TAPSE being consistently about 1 mm less than values obtained by the M‐mode technique. We conclude that 2D‐TAPSE can provide a reliable alternative to MM‐TAPSE to quantitatively measure right ventricular systolic function and may be especially useful in situations where retrospective comparisons are sought.

Objectives Debriefing is a common feature of technology‐enhanced simulation ( TES ) education. However, evidence for its effectiveness remains unclear. We sought to characterise how debriefing is reported in the TES literature, identify debriefing features that are associated with improved outcomes, and evaluate the effectiveness of debriefing when combined with TES . Methods We systematically searched databases, including MEDLINE , EMBASE and Scopus, and reviewed previous bibliographies for original comparative studies investigating the use of TES with debriefing in training health care providers. Reviewers, in duplicate, evaluated study quality and abstracted information on instructional design, debriefing and outcomes. Effect sizes ( ES ) were pooled using random‐effects meta‐analysis. Results From 10 903 potentially eligible studies, we identified 177 studies (11 511 learners) that employed debriefing as part of TES . Key characteristics of debriefing (e.g. duration, educator presence and characteristics, content, structure/method, timing, use of video) were usually incompletely reported. A meta‐analysis of four studies demonstrated that video‐assisted debriefing has negligible and non‐significant effects for time skills ( ES = 0.10) compared with non‐video‐assisted debriefing. Meta‐analysis demonstrated non‐significant effects in favour of expert modelling with short debriefing in comparison with long debriefing (ES range = 0.21–0.74). Among studies comparing terminal with concurrent debriefing, results were variable depending on outcome measures and the context of training (e.g. medical resuscitation versus technical skills). Eight additional studies revealed insight into the roles of other debriefing‐related factors (e.g. multimedia debriefing, learner‐led debriefing, debriefing duration, content of debriefing). Among studies that compared simulation plus debriefing with no intervention, pooled ES s were favourable for all outcomes (ES range = 0.28–2.16). Conclusions Limited evidence suggests that video‐assisted debriefing yields outcomes similar to those of non‐video‐assisted debriefing. Other debriefing design features show mixed or non‐significant results. As debriefing characteristics are usually incompletely reported, future debriefing research should describe all the key debriefing characteristics along with their associated descriptors.

Background— The incidence and impact of clinical stroke and silent radiographic cerebral infarction complicating open surgical aortic valve replacement (AVR) are poorly characterized. Methods and Results— We performed a prospective cohort study of subjects ≥65 years of age who were undergoing AVR for calcific aortic stenosis. Subjects were evaluated by neurologists preoperatively and postoperatively and underwent postoperative magnetic resonance imaging. Over a 4-year period, 196 subjects were enrolled at 2 sites (mean age, 75.8±6.2 years; 36% women; 6% nonwhite). Clinical strokes were detected in 17%, transient ischemic attack in 2%, and in-hospital mortality was 5%. The frequency of stroke in the Society for Thoracic Surgery database in this cohort was 7%. Most strokes were mild; the median National Institutes of Health Stroke Scale was 3 (interquartile range, 1–9). Clinical stroke was associated with increased length of stay (median, 12 versus 10 days; P =0.02). Moderate or severe stroke (National Institutes of Health Stroke Scale ≥10) occurred in 8 (4%) and was strongly associated with in-hospital mortality (38% versus 4%; P =0.005). Of the 109 stroke-free subjects with postoperative magnetic resonance imaging, silent infarct was identified in 59 (54%). Silent infarct was not associated with in-hospital mortality or increased length of stay. Conclusions— Clinical stroke after AVR was more common than reported previously, more than double for this same cohort in the Society for Thoracic Surgery database, and silent cerebral infarctions were detected in more than half of the patients undergoing AVR. Clinical stroke complicating AVR is associated with increased length of stay and mortality.
