Thrombotic calcific mitral stenosis. Morphology of the calcific mitral valve.
We compared the morphology of the calcific stenotic mitral valve (CSMV) with noncalcific stenotic mitral valves (NCSMV) removed at surgery; control valves were obtained at autopsy. X-rays of the excised valves permitted localization and quantitation of calcification. A classification of CSMV applicable to noninvasive techniques based on this methodology is presented. Moderate to heavily CSMV ha...
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...
متن کاملPercutaneous mitral valvuloplasty in an adult patient with calcific rheumatic mitral stenosis.
A 75 year old man with long-standing rheumatic mitral stenosis who refused surgical intervention was treated with percutaneous balloon valvuloplasty. Prevalvuloplasty evaluation revealed a heavily calcified mitral valve, a mean transvalvular gradient of 18 mm Hg, a Fick cardiac index of 1.7 liters/min per m2, a mitral valve area of 0.6 cm2 and 1 + mitral regurgitation. After transeptal catheter...
متن کاملCalcific 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...
