Porcine heterograft valve replacement in carcinoid heart disease
FJ Schoen, RJ Hausner, JF Howell, HL Beazley and JL Titus
A 53-year-old man with a pancreatic carcinoid tumor and liver metastases
had the carcinoid syndrome with involvement of the tricuspid valve by
carcinoid plaque. The mitral valve was involved by unrelated myxomatous
degeneration (floppy valve). Each valve was replaced by a Hancock
glutaraldehyde-prepared porcine heterograft prosthesis. When the patient
died of complications of the tumor 8 months postoperatively, both valves
had clinically normal function. Nevertheless, the carcinoid plaque, which
was present in all four cardiac chambers and almost completely covered the
endocardial surfaces of both atria, extended onto both prostheses. This
eventually might have interfered with prosthetic valve function.
