简要总结
The development of a high grade AV-block is a frequent complication associated with transcatheter aortic valve implantation (TAVI). Patients who were suitable for TAVI will be enrolled in this study. The HV-interval will be determined before and immediately after implantation.
The hypothesis is that a prolonged HV-interval is associated with a high rate of complete AV-block following TAVI.

结局指标
主要结局
Determination of HV interval
时间窗: Changes in Baseline to 24 hours
HV-interval will be determined by a 5F quadripolar electrode catheter with a CRD-2 curve configuration. Intracardiac signals will be assessed and determined before and after implantation.
次要结局
- AV-block development after 1 month, 6 months and 12 months(1 month, 6 months and 12 months)
