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. ⋯ 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.

The collateral perfusion via the hypertrophied internal thoracic arteries and rich anastomosis between the epigastric arteries reconstituting femoral artery are an important route in patients with peripheral vascular disease (chronic aortoiliac occlusion), providing blood flow to the lower extremities. Selective angiography of the internal thoracic artery plays a major role in the preoperative evaluation in patients with severe aortoiliac occlusive disease undergoing coronary bypass surgery and may prevent a major potential postoperative complication of acute lower extremity ischemia in these patients.
