Eur J Cardiothorac Surg

Objective: The Hancock II (HII) is a second-generation porcine bioprosthesis introduced into clinical use in 1982. This study aimed to evaluate very long-term outcomes for the HII valve in a large patient population.
Methods: Between May 1983 and November 1993, 517 consecutive patients (pts) (309 male, mean age: 64+/-9 years) underwent valve replacement (VR) surgery with HII, with 302 (58.

Article Synopsis
- The study analyzed 15-year outcomes for 1,274 patients who received either aortic or mitral valve replacements using the Hancock II bioprosthesis across hospitals in the Venetian area.
- The overall 15-year survival rate was 39.7%, with survival influenced by factors such as gender, heart function class, and presence of coronary artery disease; aortic valve replacements had better outcomes for embolism and reoperation rates.
- Patients over 60 years showed a 96.5% freedom from structural valve deterioration after aortic valve replacement compared to 88% for mitral, indicating better longevity of aortic implants, especially in older patients.

Objective: We performed a multi-institutional study to compare the long-term structural valve deterioration of isolated Hancock Standard versus Hancock II bioprostheses.
Methods: From 1983 to 2002, 714 Hancock Standard and 1293 Hancock II bioprostheses were implanted at hospitals of the Venetian territory (Padova, Treviso, and Venice). Follow-up on January 1, 2003, included 14,749 patient-years with a median of 12 years and was 96% complete: 115 Hancock Standard and 53 Hancock II bioprostheses were at risk at 15 years.
Background: The aim of this study was to evaluate the performance of cryopreserved aortic allografts (CAA) in the treatment of adult aortic valve pathologies.
Methods: Between May 1992 and October 2002, 122 CAA were implanted in 119 adult patients with pathologies of the aortic valve. The mean age of the patients was 38.
