Abstract:
Endomyocardial biopsy and hemodynamic study were made with the heart catheterization in 8 patients with Keshan disease. The procedure was performed smoothly and safely in all patients, without complications. Endomyocardial tissues were obtained from these eight patients. Light and electronmicroscopic observations showed that the endocardium is normal in all biopsy specimens, but abnormal morphologic findings, such as degeneration of the myocardiaum, hypertrophy of muscle fibers, old scars, etc., were present in all patients. Infiltration of interstitial fatty tissue was found in 4 cases. Heart catheterization. 2 patients with latent Keshan disease were normal. There was an increase in the pulmonary arterial pressure in 5 out of 6 patients with chronic type, and 2 showed distinct pulmonary arterial hypertension. Thus, endomyocardial biopsy may be regarded as a better method to examine the myocardium, and it is of value in diagnosis and prognosis.
