Pd. Kvidal et al., LONG-TERM FOLLOW-UP-STUDY ON 64 ELDERLY PATIENTS AFTER BALLOON AORTICVALVULOPLASTY, Journal of heart valve disease, 6(5), 1997, pp. 480-486
Background and aims of the study: The aims of this study were to evalu
ate symptomatic improvement and event-free/overall survival after ball
oon aortic valvulotomy in patients with significant sclerotic aortic v
alve stenosis. Methods: Sixty-four patients with calcified aortic sten
osis, in NYHA class III-IV, and of mean age 79.0 years, underwent a to
tal of 75 scheduled attempts at balloon aortic valvulotomy, with singl
e balloon catheters between December 1987 and June 1993. Patients were
either considered as poor surgical candidates or themselves preferred
such valvulotomy. Results: Periprocedural major complications, includ
ing death in 6%, occurred in association with 16% of the procedures. A
mong 57 patients ist whom initial dilatation was successful, the avera
ge period of symptom relief was 9.4 months (median 7.0, range: 0 to 47
months). Independent predictors for longer duration of symptom relief
and survival were systolic arterial pressure >115 mmHg and female gen
der; ejection fraction greater than or equal to 30% was only predictiv
e of survival. Actuarial survival rates at one, two and three years we
re 77, 48 and 36% respectively, Conclusions: Balloon aortic valvulotom
y is followed by a short period of symptomatic relief and carries a lo
w periprocedural mortality, but considerable morbidity. By comparison,
aortic valve replacement patients aged over 70 and with serious physi
cal limitations (NYHA class IIIB-IV) showed much better overall surviv
al. As contraindications to surgery are in most cases relative, aortic
valve replacement should always be considered as the only choice in t
he surgical decision-making.
