This type of complication has been also reported with self-expanding nitinol endovascular stent grafts for treatment of abdominal and thoracic aorta aneurysms.</li> <li id="hl0000120">Recognizing infolding before the complete release of the valve allows to prevent extreme hemodynamic instability, that can be fatal.</li> <li id="hl0000123">The guidewire in the correct position in left ventricle should never be withdrawn or lost. So that the malfunctioning infolded valve can be corrected by post-dilation.</li> <li id="hl0000126">To our knowledge, this is the first case of valve infolding in a patient with<span> </span><i>Bicuspid Aortic Valve<span> </span></i>(BAV) stenosis early recognized by rotational fluoroscopy.</li> </ul>
