Long-lasting durability of Carpentier-Edwards pericardial bovine bioprosthesis in mitral position - a case report of unfavourable post redo valve surgery course

Abstract

We describe a 73 year-old patient with mitral valve pericardial bioprosthesis Carpentier-Edwards 29M implanted due to the rheumatic mitral stenosis 21 years ago. Hemodynamic destabilisation had emerged 18 months before the admission. Echocardiography revealed significant bioprosthesis degeneration with calcification of its leaflets, small pannus on the bioprosthetic ring, moderate mitral stenosis, severe mitral and tricuspid regurgitation with high pulmonary hypertension and moderate aortic regurgitation. Redo valve surgery with mechanical Medtronic 27M valve implantation and tricuspid suture annuloplasty was successfully performed. The postoperative course was complicated by bleeding and severe respiratory insufficiency and the patient died 3 weeks after the surgery.
