Syphilitic Heart Disease

Syphilitic Heart Disease is a serious condition that affects the heart, caused by a long-term infection with the bacterium Treponema pallidum. This disease primarily damages the aorta, the large blood vessel that carries blood from the heart to the rest of the body. Over time, the infection causes inflammation and scarring of the aortic wall, leading to problems like aortic aneurysm or aortic valve insufficiency. These changes can weaken the heart's ability to pump blood effectively, causing symptoms such as chest pain, shortness of breath, and heart failure. The condition usually develops many years after the initial syphilis infection if left untreated. It is a late complication of tertiary syphilis, highlighting the importance of early diagnosis and treatment of syphilis infections.

Syphilitic Heart Disease is a manifestation of tertiary syphilis characterized by chronic inflammation of the aortic root and ascending aorta due to infection with Treponema pallidum. The hallmark pathology is endarteritis obliterans of the vasa vasorum, leading to ischemic injury of the aortic media, resulting in aortitis, medial necrosis, and fibrosis. This process causes aortic dilation, aneurysm formation, and aortic valve insufficiency, which can progress to congestive heart failure. The disease typically presents decades after the initial untreated syphilis infection. Histologically, there is a dense plasma cell infiltrate and destruction of elastic fibers in the aortic wall. Clinically, it is significant due to its potential for life-threatening complications such as aortic rupture and severe valvular dysfunction.
