Abstract
Transcatheter aortic valve implantation (TAVI) is relatively contraindicated in the bicuspid aortic valve, and to our knowledge has not been tried where the true native annulus is of a size far in excess of current device capabilities. We present here a case of a successful emergency TAVI of a 73-year-old previously healthy man, who presented with cardiogenic shock, ventricular tachycardia storm and severe left ventricular dysfunction because of the underlying critical bicuspid aortic stenosis with aortic annulus area of 991.9 mm2 and associated moderate aortic incompetence (the Society of Thoracic Surgeons (STS) risk score; score mortality of 40.9%). Despite the critical condition of the patient and technically challenging anatomy, successful TAVI was performed and the patient remains well with near-normal left ventricle (LV) function at 6 months follow-up.
