[Balloon valvuloplasty of the aortic valve: short-term and medium-term results in 50 patients].

Fifty patients with severe symptomatic aortic stenosis underwent a balloon valvuloplasty of the aortic valve with acceptable initial haemodynamic results. Follow-up at one month showed clinical improvement in 66% of the patients. Long-term follow-up (clinical, Doppler echocardiography and repeat cardiac catheterization) was disappointing. The intervention-free rates at one and two years were 44% and 26%, respectively. Aortic balloon valvuloplasty should be limited to patients with a severe aortic stenosis and short life expectancy because of non-cardiac disease and to patients with severely depressed left ventricular function as a bridge to valve replacement.
