- Idiopathic degenerative diseases of the conduction system Lev disease: This is due to progressive degenerative fibrosis and calcification of the neighboring cardiac structures, "sclerosis of the left side of cardiac skeleton," including mitral annulus, central fibrous body, membranous septum, base of the aorta, and crest of the ventricular septum. Lev disease has an onset about the fourth decade and is believed to be secondary to wear and tear on these structures caused by the pull of the left ventricular musculature. It affects the proximal bundle branches and is manifested by bradycardia and varying degrees of AV block. Lenègre disease: This is an idiopathic, fibrotic degenerative disease restricted to the His-Purkinje system. It is caused by fibrocalcareous changes in mitral annulus, membranous septum, aortic valve, and crest of the ventricular septum. These degenerative and sclerotic changes are not attributed to inflammatory or ischemic involvement of adjacent myocardium. Lenègre disease involves the middle and distal portions of both bundle branches and affects a younger population than Lev disease.
