title: Delayed left main stem obstruction following successful TAVI with an Edwards SAPIEN XT valve: successful resuscitation and percutaneous coronary intervention using a non-invasive automated chest compression device (AutoPulse).
abstract: Acute coronary artery obstruction at the time of device implantation is a recognized, albeit rare, complication of TAVI and is most frequently managed by emergency percutaneous intervention. This complication usually manifests with circulatory collapse due to compromising left ventricular ischemia and is most often observed immediately following valve deployment in the catheter laboratory or in theater. Immediate circulatory support is often necessary. We describe the first report of delayed left main stem obstruction 3.5 hours after successful deployment of a 26 mm Edwards SAPIEN XT valve via transfemoral implantation, with sudden development of circulatory collapse on the ward. Circulatory support was rapidly and effectively instituted with an automated non-invasive cardiac massage device, AutoPulse, that delivers continuous chest compressions. Successful emergency percutaneous intervention was then undertaken to the left main stem to displace a calcified nodule during automated external cardiac massage with the AutoPulse.
