Transcatheter aortic valve implantation (TAVI) is an emerging surgical approach in patients with severe aortic stenosis unsuitable for conventional aortic valve replacement (AVR). TAVI has been performed through both transfemoral and transapical approaches, each with a specific suitability criterion. A transaortic (TAo-TAVI) approach has been recently established at the authors' institution for high-risk patients who are unsuited to the above techniques. Herein, the case is described of a successful aortic valve implantation using TAo-TAVI in a patient with porcelain ascending aorta that was identified as an incidental finding during conventional AVR. The patient recovered well and was discharged home without any complications.
