ABSTRACT
Percutaneous balloon valvotomy was performed in 21 cases (aged 6 to 62 years) with moderate to severe aortic valve stenosis, using either single (16 cases) or double balloon (5 cases) technique. All patients had basal transaortic pressure gradient 50 mmHG or above. A majority of patients had significant haemodynamic improvement immediately following balloon dilatation. The mean systolic transaortic pressure gradient reduced from 94 mmHg (range 50 to 160) to 42 mmHg (range 14 to 82; P less than 0.05) immediately after the dilatation. The final gradient was less than 40 mmHg in 11 cases. The mean cardiac index improved from 3.86 L/min/M2 (range 2.8 to 5.2) to 4.14 L/min/M2 (range 3.4 to 5.6; PNS) following the procedure. There was no death or major complication related to the intervention. There was a procedure-related mild aortic regurgitation in 4 cases. We conclude that percutaneous balloon dilatation is an effective, safe, low cost, nonsurgical method for treating patients with aortic valve stenosis.
