[Percutaneous transluminal valvuloplasty of the mitral valve].
Percutaneous transluminal balloon valvuloplasty for mitral stenosis represents an alternative method of treatment to standard surgical procedures of open or closed commissurotomy as well as valve replacement. In this overview, our results will be reported with respect to derivation of a summary of indications and contraindications for the procedure. Valvuloplasty for mitral stenosis was carried out in 62 patients, mean age 43 +/- 17 years, 48 women and 14 men. In 14 of the patients surgical procedures had been performed previously including an open or closed commissurotomy or isolated aortic valve replacement. Nine patients were in NYHA class II, 50 in class III and three in class IV. Markedly impaired motion of the valve and calcification was present in 15 patients. In 47 patients, the valve motion was relatively good and associated with mild changes in the subvalvular apparatus in 29 and marked changes in 18. In 54 patients the valvuloplasty was carried out with a combination of two balloon catheters, one 3 X 10 mm trefoil catheter and a single-balloon catheter of 15 mm (n = 16) or 19 mm (n = 38) diameter. Both catheters were inserted via the right femoral vein. The procedure required an average of one and one-half hours. Before and after valvuloplasty, complete right heart catheterization with oxymetric determinations were carried out to detect possible shunts at the atrial level and left ventriculography for detection of mitral regurgitation was performed in addition to echocardiography and Doppler examinations with continuous, pulsed-wave and color Doppler studies.(ABSTRACT TRUNCATED AT 250 WORDS)
