Due to Syphilitic aortitis (a complication of tertiary syphilis) the aortic valve ring becomes dilated. The free margins of valve cusps no longer approximate leading to aortic valve insufficiency. As blood regurgitates into the left ventricle between each systole, volume overload ensues and the ventricular wall hypertrophies in an attempt to maintain cardiac output and blood pressure. The massive ventricle can lead to a heart weighing over 1000 grams (the weight of a normal heart is about 350 grams), referred to as<unk>  (Latin for cow's heart). Fluri and Gebbers define<unk>  as a heart exceeding 500 g in weight. Looking through autopsies on Internal Medicine patients at the Kantonsspital Luzern, they found 415 cases out of 1181 autopsies in the two periods 1978-81 and 1997-2000.<unk>  was found in 25.3% of cases in the earlier period, with mean age at death 67.7 years, and in the later period 20.6% with mean age 74.3 years. The male female ratio was 4:1. "In 93% of all patients with CB, we found<unk> onary atherosclerosis as a sign of high blood pressure and in 79% a COPD." In 84% of cases the cause of death was directly related to the<unk> , but in 37% the cause of death was still unclear. They concluded that<unk>  was a decreasing but still frequent autopsy finding. High blood pressure, COPD and male sex were the main risk factors. The decreasing incidence was ascribed to improved medical management: they mention treatments for high blood pressure and<unk> onary artery disease, which suggests that "COPD" in their abstract refers to the latter.
