Implication
May support intraoperative TAVI bailout for unexpected calcification in planned AVR; single case leaves open need for prospective validation.
Structured PICO
P
Population
73-year-old woman with severe aortic stenosis and impaired left ventricular function, initially planned for surgical aortic valve replacement but found intraoperatively to have severe calcification of the aortic annulus, coronary ostiae, and proximal ascending aorta making surgical implantation impossible (n=1).
I
Intervention
Transcatheter aortic valve implantation (TAVI) using a CoreValve ReValving System prosthesis, delivered through the ascending aorta.
O
Outcome
Procedural success and post-procedural recovery (functional capacity, aortic valve area, and left ventricle function).
TAVI can serve as a successful intraoperative bailout strategy when planned surgical aortic valve replacement is deemed impossible due to severe, unexpected calcification discovered during surgery.
