Description
A heart pump patient grew a fibrous curtain that sealed her replacement valve shut, and Rohan Joshua Krishnaswamy and co-authors report the case in a 2024 paper. The woman, 49, had lived nearly seven years on a ventricular assist device while waiting for a transplant her immune system kept refusing. A tissue aortic valve had been fitted partway through that wait.
Scans at one and two years showed the valve never opening, with no flow through the outflow tract, yet the cause stayed invisible. Only after transplant, when the old heart was examined, did the truth appear. A pannus, a sheet of fibrous tissue with chronic inflammatory cells, had grown across the valve's underside. It had obliterated the outlet entirely. The authors warn that in pump patients, whose valves barely open anyway, such overgrowth can hide from ultrasound until it is complete.
