    Abstract:
    Between February, 1986 and October, 1987 percutaneous aortic valvuloplasty was attempted in 78 patients: 25 men (32 p. 100) and 53 women aged from 61 to 89 years (mean 79.5 years). All patients were symptomatic; 9 were in class II, 49 in class III and 20 in class IV of the NYHA classification. The decision to try percutaneous valvuloplasty was determined by the high surgical risk associated with age (over 75 in 87 p. 100 of the patients), poor physiological condition or concurrent pathology, or by refusal of surgery. 70 dilatations could actually be made (90 p. 100) either by the brachial route (n = 39) or the femoral route (n = 18) or the transseptal route (n = 7) or by a combined brachial and femoral route which enabled the double balloon technique to be used (n = 6). The procedure comprised 5.6 +/- 3 inflations and lasted for 58 +/- 29 min. The diameter of the largest balloon utilized was greater than 20 mm in 75 p. 100 of the cases. Dilatation reduced the aortic gradient from 62 to 28 mmHg (p less than 0.001) without altering the cardiac index (2.36 to 2.32 l/min/m2) and significantly increased the aortic valve area from 0.49 to 0.76 cm2 (p less than 0.001). At the end of the procedure the aortic valve area was greater than 0.7 cm2 in 63 p. 100 and greater than 1 cm2 in 14 p. 100 of the patients. Five patients had to be operated upon within the month following dilatation (3 after technical failure, 2 for poor functional results).(ABSTRACT TRUNCATED AT 250 WORDS)
