  A 78-year-old woman with severe aortic stenosis underwent transcatheter aortic valve implantation (TAVI) with a balloon expandable bioprosthesis: a 23-mm Sapien XT valve (Edwards Life Sciences, Inc., CA, USA). A set of the valve and a balloon (NovaFlex, Edwards Transfemoral Balloon Catheter, Edwards Life Sciences, Inc., CA, USA) was successfully delivered to an optimal position using a 16-French expandable introducer hydrophilic sheath. Inflation of the balloon was commenced, and expansion was initially smooth. However, it ruptured immediately before completion of expansion, resulting in a rapid deterioration in hemodynamics. Even though no migration of the stent valve was observed, transesophageal echocardiography and aortography revealed massive paravalvular aortic regurgitation (AR), suggesting that AR was attributable to insufficient expansion. After post -dilatat.. Read More»
