title: Symetis valve implantation in failing freestyle with close proximity between coronary Ostia and annulus.
abstract: Transcatheter treatment of patients with degenerated aortic valve stentless prosthesis and low proximal coronary ostia to the aortic annulus remain a challenge because of the elevated risk for coronary obstruction. Newer generation transcatheter aortic valve devices that engage and pull the aortic valve calcium towards the aortic annulus may be beneficial in these patients. We present a case of successful treatment of a degenerated tubular stentless prosthesis with low coronary ostia with a Symetis Acurate TA prosthesis.
