[Short- and mid-term results of percutaneous aortic valvuloplasty for calcific aortic stenosis in elderly patients].
In order to evaluate the short and mid-term results of percutaneous aortic balloon valvuloplasty, 40 consecutive elderly patients with symptomatic severe calcific aortic stenosis, underwent the procedure consecutively, with follow-up by clinical evaluation and Doppler echocardiography. Over a mean follow-up period of 11.2 months there were 5 deaths, and 12 patients underwent subsequent aortic valve replacement. Doppler echocardiography revealed an increase in aortic valve area from 0.62 +/- 0.20 cm2 to 0.91 +/- 0.23 cm2 after the procedure, but there was a significant trend toward restenosis by 12 months follow-up in 23 of 32 patients (72%). Restenosis was accompanied by symptomatic deterioration in 18 of 23 patients (78%). Although balloon valvuloplasty may often improve haemodynamics and relieve symptoms, these benefits seem to be short-lived in most cases. Restenosis has a high rate of occurrence. Aortic balloon valvuloplasty should be reserved for truly inoperable cases and for haemodynamically-unstable patients, who may later undergo surgery.
