In advanced cases, attacksof syncope are common, and the general condition of nutritionmay be considerably impaired. Pain of an angina-Hke char-acter is frequently observed. The amount of alteration in thepulse, more especially the degree of distention during theventricular diastole ; the extent of the dilatation of the leftventricle ; and the condition of the mitral valve—whethercompetent or not—are points of great importance in estimatingthe gravity of this lesion. Figure 59 represents in a diagrammatic manner the efTectsof aortic lesions upon the Fig. 59.—Representation of the effects of a lesion of the aortic valves (aorticregurgitation in this case) on the heart and circulation. The letters havethe same significance as in fig. 57. The left ventricle is hypertrophiedand dilated ; the mitral valve is as yet competent. Differential diagnosis of Cardiac Murmurs. 22 i PULMONARY AND TRICUSPID LESIONS. The effects produced by pulmonary and tricuspid lesionswill be readily understood after what has been already statedin describing the effects of mitral lesions. Pulmonary lesions—which are extremely rare, except ascongenital conditions—produce alterations in the right cavitiesof the heart and engorgement of the systemic venouscirculation. Tricuspid regurgitation (which is frequent in the advancedstages of mitral lesions, and which may also arise, as I havepreviously pointed out, from primary disease of the lungs,such as emphysema and cirrhosis) is always attended withmarked signs of sy
