Myocardial ultrastructural lesions in septic valvulopathies.
The electron microscopic aspect of the myocard fragments was examined during surgical extirpation and prosthesis of some septic valvulopathies. Various and disseminated lesions were observed. We remarked the range of mitochondrial lesions, glycogenic deletions, lysosomal activations, the intensity of interstitial and intrasarcoplasmatic oedema that disintegrate sarcolemal structures and intercalary disks. The difficulties concerning the surgical valve prosthesis on the severe toxicoseptic and hypoxic myocardial alterations were mentioned.
