Sutureless Valve Implantation in Sievers Type 0 Bicuspid Annuli: A Word of Caution

A BSTRACT Aim We describe a series of 3f Enable sutureless prostheses implanted in bicuspid valves. Methods Between March 2011 and April 2014, five patients with Sievers type 0 bicuspid valves were selected to receive the sutureless 3f Enable prosthesis . Exclusion criteria were: intraoperative calibration of the aortic annulus >27 mm, left ventricle ejection fraction <50%, age <70 years. Results All the implantations could be performed without the necessity to re‐deploy the prosthesis . The perioperative transesophageal echocardiogragram detected two moderate paravalvular leakages (PVL) in two patients who received a large size of prosthesis (25 and 27 mm, respectively). The two leakages, at a follow‐up of 32 and 24 months, respectively, increased to grade II and II +. No PVL appeared in the other three patients. Conclusion This experience should warn about the inadequate performance of the 3f Enable valve in Sievers type 0 large aortic bicuspid annuli. In this subset any minor intraoperative residual leakage should not be accepted. doi: 10.1111/jocs.12599 (J Card Surg 2015;30:694–696)
