OBJECTIVE: Sutureless prostheses for surgical @entity886 ( @entity886 ) are usually used in degenerative calcified @entity472 . Less is known on the application of sutureless prostheses for pure @entity337 . METHODS: Between 2011 and 2014, 442 @entity1 were operated on with the Perceval aortic sutureless valve implant. We identified 11 @entity1 (10 female, mean age 70.5) who underwent sutureless @entity886 for pure @entity337 (off-label use). Three @entity1 had a left ventricle ejection fraction of 30% or less. Mean logistic EuroSCORE was 15.2 (range 2.2-45.2). In five @entity1 associated mitral procedures (three [60%] repair and two [40%] replacement) were performed. Four procedures were performed through a minimally invasive approach (three right minithoracotomies and one partial sternotomy). RESULTS: Mean cardiopulmonary bypass time was 130.2   min and aortic cross clamp time was 82.2   min. Mean implanted prosthesis size was 24.5        1.3 (median 25) mm (insignificant correlation with preoperative aortic valve annulus measurement by transthoracic echocardiography: 21.6        1.5 [median 21] mm, Pearson's r   =   0.373, p   =   0.259). One @entity1 died on 24th day after @entity886 associated with aortic arch replacement and hypothermic @entity1167 (10 years after correction for @entity1580 ). No residual para- or intravalvular leakage was present on discharge and 12-month follow-up. No migration of the prosthesis occurred. CONCLUSION: Sutureless @entity886 is an option in selected @entity1 with @entity337 . Preoperative aortic annulus measurement by echocardiography has poor predictive value for estimation of prosthetic valve size.
