Vascular complications with transcatheter aortic valve implantation using the 18 Fr Medtronic CoreValve System: the Rotterdam experience.

Author information

Department of Cardiology, Thoraxcentre, Erasmus Medical Centre, Rotterdam, The Netherlands.



Transcatheter aortic valve implantation (TAVI) requires large bore catheters. Access site complications, therefore, can be a concern. The aim of this study is to present the 30-day incidence of major and minor vascular complications in patients treated with the third generation 18 Fr Medtronic CoreValve System.


We prospectively evaluated the vascular complications occurring in all patients treated with the 18 Fr Medtronic CoreValve System between October 2006 and October 2009 in the Thoraxcenter using various proposed definitions. Ninety-nine consecutive patients were treated with TAVI using the 18 Fr Medtronic CoreValve System. Vascular events were encountered in 13 patients (13%), seven of these cases (54%) were related to incomplete arteriotomy closure with the Prostar device which is the default access closure technique in our centre. Depending on how major vascular complications were defined, the incidence varied from 4 to 13%. Blood transfusions in combination with surgical or percutaneous intervention were required in eight cases.


Transcatheter aortic valve implantation with the 18 Fr Medtronic CoreValve System(R) has a 4 to 13% vascular complications' rate. More than half of the vascular events were due to incomplete Prostar arteriotomy closure, despite its use by experienced operators. Current percutaneous closure devices for these large arteriotomies seems suboptimal. Uniformity in how to define TAVI related vascular complications is needed.
