The following was published in an article titled "transseptal puncture in children under 20 kg", the author(s), 2022.Published by cambridge university press, volume 32, supplement 2, pages s1¿s279.Between january 2006 and july 2021 33 berlin heart excor© devices were implanted in paediatric patients.We analysed preoperative and intraoperative characteristics, as well as complications after the implant (haemorrhagic, infectious, thromboembolic and neurological).Outcomes of the patients were also evaluated (transplant vs.Death).Sa total of 21 patients were included in this study.Eight of them were girls.The mean age of the patients was 3.4 years (0 days-8.4 years).9/21 of these patients had a bodyweight of less than 10 kg, and the remaining 12/21 patients were between 10-20 kg (mean 11 kg (2.7-20kg)).The median procedure and fluoroscopy times were 140 min and 3 min, respectively.Tp was performed in 7 patients during an electrophysiological study due to svt.Tp was performed in 7 patients with hypoplastic left heart syndrome to create an interatrial shunt.In 7 patients, tp was performed to cre-ate a right-left shunt due to pulmonary hypertension.Tp was not successful in 4 patients.The mean weight of the patients who failed tp was 4.5 kg.The only major complication was pericardial tamponade developed in a patient diagnosed with complex congenital heart disease(chd).Conclusion: in conclusion, transseptal puncture can be performed safely in suitable patients.It may be riskier in complex chd patients with abnormal cardiac anatomy than patients with normal cardiac anatomy performed for the electrophysiological study.Pericardial effusion/cardiac tamponade occurred during the study.

The results of the investigation are inconclusive since the device was not returned for analysis.Review of the device history record was not possible as the lot number is unknown.Based on the information received, the cause of the reported pericardial effusion/cardiac tamponade remains unknown.Per the ifu, cardiac perforation is a known risk during the use of this device.
