Earlier studies that investigated the relation of atrioventricular (AV) conduction system to perimembranous ventricular septal defect (pmVSD) were based on cardiopathological specimens. To study the relationship of conduction system to pmVSD using 3-dimensional electroanatomic mapping system (EAMS) in patients undergoing device closure. Fifteen consecutive cases of pmVSD from January 2014 to July 2017 (age > 2 years and weight > 8 kg) were included in the study. The course of conduction system and its relationship with the pmVSD was mapped before and after device closure, with the use of EAMS. Median age and weight of the cohort was 10 years (range 4-21 years) and 25 kg (range 13-55) respectively. Device implantation was successful in all patients except 1. The course and relation of the conduction system were posteroinferior to the pmVSD in all cases (100%), and away from the defect in 67% (10/15). In patient with baseline RBBB, the right-sided conduction system was in close proximity to the pmVSD. Two patients had part of left-sided conduction system in close proximity to pmVSD or device edges. Two patients developed RBBB following device deployment, which reverted to normal on follow up. No patient developed high grade AV block during the median follow-up of 34 months (range 24-62). This experimental study has shown the feasibility of 3D EAM of conduction system during device closure of pmVSD. This novel concept can be utilized to understand the anatomy of conduction system in other congenital heart diseases.

在接受膜周室间隔缺损的经导管装置闭合术的患者中绘制传导系统图:概念验证研究。

早期研究房室 (AV) 传导系统与膜周室间隔缺损 (pmVSD) 的关系是基于心脏病学标本。使用 3 维电解剖标测系统 (EAMS) 在接受装置闭合的患者中研究传导系统与 pmVSD 的关系。研究纳入了 2014 年 1 月至 2017 年 7 月(年龄 > 2 岁,体重 > 8 kg)的 15 例 pmVSD 连续病例。使用 EAMS 绘制了设备闭合前后传导系统的过程及其与 pmVSD 的关系。该队列的中位年龄和体重分别为 10 岁(范围 4-21 岁)和 25 公斤(范围 13-55)。除 1 例患者外,所有患者均成功植入装置。传导系统的过程和关系在所有情况下(100%)都落后于 pmVSD,67%(10/15)远离缺陷。在基线 RBBB 患者中,右侧传导系统非常靠近 pmVSD。两名患者的左侧传导系统部分靠近 pmVSD 或设备边缘。两名患者在设备部署后出现 RBBB,在随访中恢复正常。在 34 个月的中位随访期间(范围 24-62),没有患者出现高级别 AV 阻滞。该实验研究表明了在 pmVSD 设备闭合期间传导系统的 3D EAM 的可行性。这一新概念可用于了解其他先天性心脏病中传导系统的解剖结构。右侧传导系统靠近 pmVSD。两名患者的左侧传导系统部分靠近 pmVSD 或设备边缘。两名患者在设备部署后出现 RBBB,在随访中恢复正常。在 34 个月的中位随访期间(范围 24-62),没有患者出现高级别 AV 阻滞。该实验研究表明了在 pmVSD 设备闭合期间传导系统的 3D EAM 的可行性。这一新概念可用于了解其他先天性心脏病中传导系统的解剖结构。右侧传导系统靠近 pmVSD。两名患者的左侧传导系统部分靠近 pmVSD 或设备边缘。两名患者在设备部署后出现 RBBB,在随访中恢复正常。在 34 个月的中位随访期间(范围 24-62),没有患者出现高级别 AV 阻滞。该实验研究表明了在 pmVSD 设备闭合期间传导系统的 3D EAM 的可行性。这一新概念可用于了解其他先天性心脏病中传导系统的解剖结构。在 34 个月的中位随访期间(范围 24-62),没有患者出现高级别 AV 阻滞。该实验研究表明了在 pmVSD 设备闭合期间传导系统的 3D EAM 的可行性。这一新概念可用于了解其他先天性心脏病中传导系统的解剖结构。在 34 个月的中位随访期间(范围 24-62),没有患者出现高级别 AV 阻滞。该实验研究表明了在 pmVSD 设备闭合期间传导系统的 3D EAM 的可行性。这一新概念可用于了解其他先天性心脏病中传导系统的解剖结构。
