Abstract: | Investigations of laser-induced fluorescence spectra for human cardiac valve tissue with calcinosis are performed as compared
to similar spectra of bone and myocardial tissue of an animal that are excited by an excimer laser with a 248-nm wavelength.
It is shown that a healthy tissue has a laser-induced fluorescence maximum in the region of 300–400 nm which corresponds to
protein tissue luminescence. For tissue affected by calcinosis, the laser-induced fluorescence spectra differ significantly
from the spectra of healthy tissue and have a maximum in the region of 400–500 nm. The obtained results offer the prospects
for using laser-induced fluorescence to diagnose tissue with calcinosis in open-heart surgery.
