Abstract:
The so-called Gamna-Gandy body is a sclerosiderotic granulomatous lesion composed of degenerate collagen fibers encrusted with iron and calcium. Only five cases of Gamna-Gandy body in the heart have been documented. We studied 7 patients with cardiac myxoma who underwent surgery in our university hospital, and Gamna-Gandy body was present in 3. All the Gamna-Gandy body-positive patients had ingested anticoagulant agents and/or antiplatelet drugs. These results suggest that the Gamna-Gandy body in cardiac myxoma is not a rare pathologic condition and that anticoagulant and/or antiplatelet therapy may have a causal relation to the pathogenesis of this lesion.

Specialized Characteristics of Cardiac Muscles
Cardiac muscle cells are smaller than skeletal muscles, averaging 10–20 mm in diameter and 50–100 mm in length. However, they have large energy demands for continuous contraction and relaxation. This energy is almost exclusively derived from aerobic metabolism of energy...
