Abstract

Objectives To describe results from our "modified crossover technique" for vascular access management during transcatheter aortic valve implantation (TAVI). Background Vascular access management remains a major cause of complications following TAVI due to the large bore sheaths required. Methods All suitable patients undergoing TAVI in our center, between June and August 2011, underwent our "modified crossover technique," which enables the passage of a balloon through left radial access and inflation in the proximal iliac to allow percutaneous closure in a clean field. Results In total, 15 patients were included: the logistic EuroSCORE was 19.7 ± 12.1% and STS score 5.7 ± 5.6%. The mean therapeutic femoral access site diameter was 8.1 ± 1.0 mm. Ten (66.7%) patients received Edwards SAPIEN™ XT (two using the new E-sheath) and five (33.3%) patients a Medtronic CoreValve ReValving System® device. The "modified crossover technique" was used successfully in all patients. There were three vascular complications occurring at the therapeutic access site: one rupture of the external iliac artery, one Prostar failure, and one pseudoaneurysm of the right common femoral artery. All complications were successfully treated percutaneously with covered stent implantation via access from the contralateral femoral artery. In view of the balloon inflation from the left radial artery, the complications could be treated in a clean field with minimal blood loss. Conclusions Our "modified crossover technique" using the left radial artery as the diagnostic site for balloon inflation appears a helpful adjunct in managing TAVI vascular access sites.
