Background:
We describe a vascular closure technique, convenient in practice, that permits effective femoral artery closure after CoreValve (Medtronic) implantation during transcatheter aortic valve implantation (TAVI). Vascular complications of transfemoral access implantation have been associated with significantly increased patient morbidity and mortality, as well as with increased hospitalization, among patients undergoing TAVI.
Technique:
The crossover technique is performed while using the sheath dilatator in order to tightly grasp the crossover wire; a peripheral artery balloon is inserted in the iliac artery and inflated above the puncture site. The 18 Fr sheath is removed while hemostasis is achieved in that way. Minor vascular complications were observed in 10% (3 out of 30) of the patients treated with this vascular closure technique. No major vascular complications were observed.
Conclusions:
The described vascular closure maneuver is operator friendly, without demanding special skills and can be added to the therapeutic quiver for minimizing vascular complications after TAVI.
