Özet

Bicuspid aortic valve (BAV) is currently considered an exclusion criterion for transcatheter aortic valve implantation (TAVI). The risk of adverse aortic events such as incomplete sealing, severe paravalvular regurgitation or dislocation due to elliptic shape and asymmetric calcifications in annulus are higher in TAVI. In this case report, we detailed a case of successful trans-femoral TAVI in a 51-year old male with BAV and its management without in-hospital and 30-day complications. The challenge in this case was the patient's anatomy with a 27-mm annulus for balloon expandable device. The applied strategy was balloon sizing and overdilating the 29-mm stented valve with additional volume that obviated re-ballooning. Trans-femoral TAVI was performed uneventfully under fluoroscopic and transoesophageal echocardiography guidance. A multidetector computed tomography (MDCT) evaluation at 1 month did not show device dislodgement or any other complications. Evidence for evaluation post-TAVI is not sufficient in BAV. We believe patients with BAV should undergo a comprehensive assessment after TAVI including MDCT evaluation.
