    MEDTRONIC RECEIVED INFORMATION VIA LITERATURE REGARDING AN EXAMINATION THE RATE AND MODE OF OCCURRENCE OF COMMISSURAL DEHISCENCE IN FIRST- AND SECOND-GENERATION PORCINE BIOPROSTHETIC VALVE EXPLANTS. ALL DATA WERE COLLECTED FROM A SINGLE CENTER BETWEEN JANUARY 1970 AND JANUARY 2004. THE STUDY ANALYZED 586 EXPLANTED BIOPROSTHESES. PATIENT DEMOGRAPHICS: PREDOMINANTLY FEMALE WITH A MEAN AGE OF 65 YEARS. OF THE EXPLANTED VALVES, 455 WERE MEDTRONIC HANCOCK STANDARD (104 AORTIC POSITION, 338 MITRAL POSITION, 13 TRICUSPID POSITION) AND 31 WERE MEDTRONIC HANCOCK II (6 AORTIC POSITION, 24 MITRAL POSITION, 1 TRICUSPID POSITION). NO SERIAL NUMBERS WERE PROVIDED. AMONG ALL HANCOCK STANDARD AND HANCOCK II PATIENTS, ADVERSE EVENTS INCLUDED: REOPERATION DUE TO STRUCTURAL VALVE DETERIORATION (MOSTLY A RESULT OF DYSTROPHIC CALCIFICATION), VALVE REPLACEMENT DUE TO VALVE INCOMPETENCE CAUSED BY COMMISSURAL DEHISCENCE (OBSERVED WITH HANCOCK STANDARD AND HANCOCK II MITRAL RECIPIENTS), CALCIFICATION/CALCIFIC DEPOSITS, AND VALVE ¿TEARS AND WEARS.¿ FOR ALL HANCOCK STANDARD AND HANCOCK II RECIPIENTS, VALVE EXPLANTATION OCCURRED AT A MEAN TIME OF 10 YEARS POST IMPLANT.
