Résumé
Früh et al. [1] report their data from a retrospective study of coarctations. The small number of patients in each group and the lopsided distribution of patients in each arm render statistical analysis meaningless. The data in the abstract are different from that in the text. [Abstract: Group A, B and C: n = 48/16/27. Results section: Group A, B and C: n = 48/17/26.] ‘In the whole group 16 patients need reintervention. In the next paragraph, it appears 15 needed reintervention [12 natives + 3 recoarctation]’. The accuracy of this dataset is questionable. There is no data on resolution of hypertension in the various groups. Were the 24 recurrent coarctations, following surgery or catheter intervention? The authors state that the complication and reintevention rates are comparable between the three groups. The primary focus is supposedly a comparison of the modalities of treatment in each group—not a comparison of overall complication and reintervention rates between the three age groups, which could all be good or all be bad! This is not in line with the primary focus of the paper. ‘In group C, stent implantation is an excellent alternative to surgery’. Do the authors recommend stent implantation as a primary modality or as ‘an alternative to surgery’. In Group B, the reintervention rates for surgery vs catheter intervention [balloons + stents] in native coarctation were 0 vs 37.5%. In recoarctation, there were no catheter interventions at all, which precludes any comparison. Based on these data, how would the authors justify catheter intervention in Group B, as part of the protocol? The 37% incidence of recoarctation following catheter intervention, despite comparable acute reductions in gradients, indicates that an acute gradient reduction is an unreliable predictor of subsequent recoarctation. In Group B, it is stated that the preference is for surgery when there is associated arch hypoplasia. Comparing isolated coarctation with that of arch hypoplasia + coarctation is to compare similar pathological entities but at different points on the spectrum of severity, which potentially biases the results against surgery. Yet, reintervention rates were lower for surgery [0 vs 37.5%]. If anything, these data suggest that surgery is a better option in Group B. The authors state that in Group B, the need for reintervention following balloon dilatation is high, and stents are not recommended due to the frequent need for redilatation. If balloons are risky, stents are not recommended and surgery has a reintervention rate of 0, why do patients in Group B have catheter intervention at all? From Table 2, it is obvious that this study has one of the shortest follow-ups, especially in Group C, where most of the patients had stent implantations. The incidence of recoaractation and reintervention could be significantly under-reported. The conclusions of the study have no direct correlation with the data presented. This is essentially an audit of one centre's practice and throws no new light on the management of coarctation.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
