Valvular heart disease.
Era Before 1950 In 1950, rheumatic valvular heart disease (VHD) was the most common cause of VHD. The link between streptococcal infection and rheumatic fever was established, and a successful trial of penicillin prophylaxis against rheumatic fever was reported.1 In 1944, Jones published a seminal article on diagnosis of rheumatic fever.2 The American Heart Association (AHA) and Circulation pla...
متن کاملValvular Heart Disease
324 Malfunction of any of the cardiac valves results in a less efficient circulatory system. Valvular dysfunction causes work overload in one or both ventricles. In extreme cases, resultant congestive heart failure can cause death. More information about etiology, pathogenesis, differential diagnoses, and diagnostic approaches used for evaluation of valvular diseases can be found in chapters 27...

An appreciation of the natural history of acquired valvular heart disease is a prerequisite to an understanding of how surgical intervention has altered the natural outlook. The prognosis for a patient with valvular heart disease treated medically is dependent on the stage of the disease at which he is first seen. Therefore, assessment for surgery requires evaluation of the pathophysiologic con...

308 As technology advances resulted in more effective percutaneous approaches to the treatment of valvular stenosis, the terminology used to describe these procedures evolved as well. The term “commissurotomy” originated from the surgical procedure developed for commissural mitral valve stenosis (see chapter 34), and some thought valvuloplasty should be reserved for surgical procedures that mor...
متن کاملValvular Heart Disease
Valvular involvement by disease causes stenosis, insufficiency (regurgitation or incompetence), or both. Stenosis is the failure of a valve to open completely, thereby impeding forward flow. Insufficiency, in contrast, results from failure of a valve to close completely, thereby allowing reversed flow. These abnormalities can be either pure, when only stenosis or regurgitation is present, or mi...
