The aim of this study is to describe the initial experience with versacross transseptal (TS) system for transseptal puncture for the transcatheter mitral valve repair using the MitraClip device.
Transeptal puncture is a key step in transcatheter mitral valve repair (MVR) and the use of the VersaCross system comprised of a sheath, a dilator and a radiofrequency wire has not been previously described.
Prospective single center study of consecutive patients undergoing transcatheter mitral valve repair with the MitraClip device were included. Targeted TS puncture was performed under transesophageal echocardiographic (TEE) guidance. Baseline demographics, procedural characteristics, and major adverse procedural events were collected.
Twenty-five consecutive patients underwent transseptal puncture using the VersaCross TS system. Transseptal puncture was successful in 100% of patients. The mean time for TS puncture was 3 3 ± 1.6 min with no major adverse procedural events. The mean time from insertion of the VersaCross system to insertion of the MitraClip guide catheter was 3.8 ± 3.0 minutes.
The VersaCross TS system was successful in all patients for MitraClip procedure with no adverse procedural events and may be associated with increased procedural efficiency.
本研究旨在描述使用 MitraClip 装置经导管二尖瓣修复术(transcatheter mitral valve repair, TMVr)中经Versacross 经间隔(transseptal, TS)系统行 TS 穿刺的初步经验。
TS 穿刺是经导管二尖瓣修复术（TMVr）的关键步骤，VersaCross 系统（由鞘管、扩张器和射频导丝组成）的使用此前尚未描述。
前瞻性纳入连续接受 MitraClip 装置行 TMVr 的患者进行单中心研究。在经食管超声心动图(transesophageal echocardiography, TEE)引导下行靶向 TS 穿刺。收集基线人口统计学、手术特征和主要不良手术事件。
25 例连续患者使用 VersaCross TS 系统行 TS 穿刺。所有患者均成功进行 TS 穿刺。TS 穿刺的平均时间为 3 3±1.6 分钟，无主要不良手术事件。从插入 VersaCross 系统到插入 MitraClip 导引导管的平均时间为 3.8±3.0 分钟。
VersaCross TS 系统在所有患者中均成功用于 MitraClip 手术，无不良手术事件，可能与手术效率提高有关。
