[Current status of aortic valvuloplasty in patients aged 80 and over. Apropos of a recent series of 70 patients (1989-90)].
In contrast with aortic valve replacement, the treatment of choice for severe aortic stenosis because of the better long-term results, percutaneous aortic valvuloplasty, has only limited indications, mainly because of the high rate of restenosis. However, in very elderly patients, the surgical risk is high, sometimes prohibitive. For this reason, the authors report their latest results with this technique in a series of octogenarians. Between January 1989 and December 1990, 70 aortic valvuloplasties were performed in octogenarians (average age 85 +/- 3 years). The indications were advanced age > or = 85 years (46%), poor left ventricular ejection fraction < 40% (20%), secere associated coronary artery disease (3%), associated extracardiac pathology (11%), poor general condition (11%) or refusal of surgery (4%). The great majority of these patients (83%) were very symptomatic: 70.5% had Grade III-IV dyspnoea, 20% had Grade III-IV angina and 20% had syncopal attacks. Valvuloplasty reduced the mean transvalvular pressure gradients from 61 +/- 23 to 30 +/- 11 mmHg (p < 0.01) and increased aortic valve surface area from 0.53 +/- 0.19 to 0.94 +/- 0.12 cm2 (p < 0.001). There were two deaths (2.9%) in the catheterization laboratory and 4 (5.7%) complications during the hospital period (myocardial infarction: 1, cerebrovascular accident: 1, severe aortic regurgitation: 1 and complete atrio-ventricular block: 1). There were no serious vascular complications. The average duration of the hospital period was 6 +/- 5 days. Clinical follow-up of 17 +/- 7 months was obtained in 97% of patients.(ABSTRACT TRUNCATED AT 250 WORDS)
