Continuous sutures in replacement of mitral and tricuspid valves with prostheses
M Murtra, E Castells, M Puig-Massana, F Martinez, J Simon and M Petit
Four years' experience with 363 patients, in whom 360 mitral and 65
tricuspid prosthetic valves have been implanted with single continuous
sutures, is presented. The occurrence of prosthetic valve detachment is
particularly discussed. There were 4 cases of detachment of the prosthetic
mitral valve and no cases of tricupsid dehiscence. All 4 patients with
detached valves required reoperation. Calcifications that penetrate into
the annulus and myxomatous degeneration of the valve are considered more
important factors in the production of prosthetic cases so long as a
uniform distribution of stitches is maintained (not too close to each
other) and excessive tension in the suture line is avoided.
