Calcific Aortic Stenosis
Calcific aortic stenosis is the most common indication for surgical valve replacement in the United States. For years this disease has been described as a passive degenerative process during which serum calcium attaches to the valve surface and binds to the leaflet to form nodules. Therefore, surgical treatment of this disease has been the approach toward relieving outflow obstruction in these ...
متن کاملCalcific pulmonic stenosis.
C ALCIFIC STENOSIS of the aortic valve is a well-recognized and relatively common clinical and pathological entity. In contrast, calcific pulmonic stenosis is rarely encountered either at operation or necropsy. We have observed small deposits of calcium in one or more pulmonic valve cusps in patients who lived into adulthood with left-toright intracardiac shunts, and in older persons with sever...

The maintenance of a normal or near-normal fterload, matched appropriately to robust myocardial conractility and accompanied by adequate venous return and eart rate, together ensure the teleologic cardiac function of e...
متن کاملCalcific Aortic Stenosis
To evaluate the short-term results of percutaneous aortic balloon valvuloplasty, 55 consecutive elderly patients with symptomatic, severe aortic stenosis who were at high risk for surgical intervention underwent the procedure, with follow-up by clinical evaluation and Doppler echocardiography. Over a mean follow-up of 6.2 months, there were three early deaths (<30 days) and eight late deaths. N...
متن کاملValvotomy in calcific mitral stenosis.
The results of transventricular mitral valvotomy in 50 cases of heavily calcified mitral stenosis are presented. The mortality and quality of results in patients undergoing a first valvotomy were more satisfactory than in patients undergoing a second operation. Associated mitral incompetence has an adverse effect on the results, particularly after a second operation. As a result, it is suggeste...
