Postprocedural aortic regurgitation (AR) is a challenging complication following transcatheter device closure of perimembranous ventricular septal defects (pmVSD) in pediatric patients. This study aimed to identify risk factors for AR and evaluate its long-term outcomes. A total of 1,427 children who underwent successful pmVSD closure between June 2002 and August 2023 were retrospectively analyzed, with a median follow-up of 80 months (range, 12 to 248). Patients were further divided into early (2002-2016) and late (2017-2023) eras to assess temporal effects. Postprocedural AR occurred in 157 patients (11.0%), including 151 new-onset and 6 aggravated cases. AR was mostly trivial or mild, with 3 moderate cases (one requiring early valve repair). AR developed in 105 patients early after closure and in 52 during follow-up. Multivariate analysis identified repeated track creations (odds ratio [OR]: 2.000; 95% confidence interval [CI]: 1.286 to 3.112; P = 0.002) and opening the left disk above the aortic valve (OR: 5.071; 95% CI: 2.476 to 10.389; P < 0.001) as independent risk factors. Subgroup analysis showed consistent findings in the early era, whereas a smaller subaortic rim emerged as an additional risk factor in the late era. At the last follow-up, 2 patients had moderate AR, 10 mild, and 62 trivial. In conclusion, most AR cases after pmVSD closure are mild or trivial with favorable long-term outcomes. Minimizing repeated track creations and avoiding opening the left disk above the aortic valve may help reduce AR risk, whereas a smaller subaortic rim may increase its likelihood.

术后主动脉瓣反流（AR）是经导管装置关闭膜周室间隔缺损（pmVSD）后儿科患者的一个具有挑战性的并发症。本研究旨在确定AR的危险因素并评估其长期预后。本研究回顾性分析了2002年6月至2023年8月期间1427例成功关闭pmVSD的儿童，中位随访时间为80个月（范围12至248个月）。患者进一步分为早期（2002-2016）和晚期（2017-2023），以评估时间效应。术后发生AR 157例（11.0%），其中新发151例，加重6例。AR大多轻微或轻微，3例中度（1例需要早期瓣膜修复）。105例患者在术后早期发生AR， 52例在随访期间发生AR。多因素分析发现，重复造径（比值比[OR]: 2.000； 95%可信区间[CI]: 1.286 ~ 3.112; P = 0.002）和主动脉瓣上方打开左盘（比值比：5.071;95% CI: 2.476 ~ 10.389; P < 0.001）是独立的危险因素。亚组分析在早期显示了一致的结果，而在晚期，较小的主动脉下边缘成为一个额外的危险因素。最后一次随访时，中度AR 2例，轻度AR 10例，轻度AR 62例。总之，大多数pmVSD关闭后的AR病例是轻微或微不足道的，长期预后良好。尽量减少重复造径和避免打开主动脉瓣上方的左盘可能有助于降低AR风险，而较小的主动脉下缘可能增加AR风险。

Compared with left heart catheterization (LHC), the pressure gradient of an aortic valve (PG_AV) measured by echocardiography during transcatheter aortic valve replacement (TAVR) in small annuli is overestimated. The purpose of this study was to improve the accuracy of PG_AV measurements by echocardiography in small annuli and to evaluate the influence of PG_AV on prognosis. The internal derivation cohort included 273 consecutive patients with aortic stenosis and a small annulus (computed tomographic scan showing an annulus circumference < 72 mm or area < 400 mm²) who underwent TAVR. Patients completed transthoracic echocardiography (TTE) and LHC measurements during TAVR, and an extreme gradient boosting (XGBoost) algorithm was trained. The primary outcome was a composite end point of all-cause mortality and readmission for heart failure. The mean PG_AV level measured by TTE was overestimated compared to the LHC measurement {52.5 [interquartile range: 47.5-57.0] mmHg vs. 42.5 (interquartile range: 38.0-46.0) mmHg, P < 0.001}. After adjustments to the XGBoost, the mean PG_AV measured by TTE could be significantly improved [Pearson correlation coefficient = 0.94, P < 0.001]. Importantly, patients with a predicted mean PG_AV ≥ 68.6 mmHg showed a significantly increased incidence of composite end points at 2 years after the procedures (40.7% vs. 16.0%, P < 0.001). The XGBoost model could effectively improve the accuracy of the mean PG_AV measured by TTE during TAVR, and the predicted mean increase in the PG_AV level may lead to a worse prognosis.Clinical Trial Registration: ClinicalTrials.gov Protocol Registration System (NCT05044338).

与左心导管（LHC）相比，经导管主动脉瓣置换术（TAVR）中超声心动图测量的小环空主动脉瓣压力梯度（PGAV）被高估。本研究旨在提高超声心动图测量小环空PGAV的准确性，并评价PGAV对预后的影响。内部衍生队列包括273例连续接受TAVR的主动脉狭窄和小环（计算机断层扫描显示环周长为2）患者。患者在TAVR期间完成了经胸超声心动图（TTE）和LHC测量，并训练了极端梯度增强（XGBoost）算法。主要终点是全因死亡率和心力衰竭再入院的综合终点。与LHC测量值相比，TTE测量的平均PGAV水平被高估了{52.5[四分位数范围：47.5-57.0]mmHg vs. 42.5(四分位数范围：（38.0 ~ 46.0） mmHg时，TTE测量的pav可显著改善[Pearson相关系数= 0.94,P AV≥68.6 mmHg显示术后2年复合终点发生率显著增加（40.7% vs. 16.0%）， TAVR期间TTE测量的PGAV水平平均升高可能导致预后较差。临床试验注册：ClinicalTrials.gov方案注册系统（NCT05044338）。
