Complications of valvular surgery--5 cases report with special reference to the conduction system--

Five interesting autopsy cases of post-valvular replacement death are reported and discussed with special reference to disturbances of the conduction system. The most important acute changes are hemorrhages; the significance of a venous hemorrhage is emphasized. Chronic changes are collagenization of conduction system. One case of mycotic valvulitis, probably due to aspergillus, and one case of dissecting aneurysm probably related to previous valve replacement surgery are included.
