Abstract

To evaluate the mid-term results of balloon pulmonary valvuloplasty (BPV) in children. Prospective study. Pediatric Cardiology Department of Queen Alia Heart (QAHI), Jordan. One hundred and thirty-two patients with a median age of 3 years (range 1 day to 16 years), underwent (BPV) between January 1999 and January 2006. We evaluated our patients with regard to peak pressure gradient across the right ventricular outflow tract before and after BPV. Thereafter we followed them at the Outpatient Clinic regarding the peak instantaneous gradient pressure, the pulmonary valve incompetence, right ventricular function based on echocardiographic findings, and the need for repeat BPV. There was significant reduction in the peak to peak gradient from 93.5 ± 32.3 mmHg to 26.1 ± 9.6 mmHg (p <  0.001). Echo-Doppler data showed that residual peak instantaneous gradient dropped from 26.1 ± 9. 6 to 19 ± 6 mmHg; (p <  0.001) on follow-up for 6 years. Mild to moderarte pulmonary valve regurgitation was noticed in 34 patients (27.8%) at one year and in 43 patients (38%) at mid term follow-up, but non had right ventricular dilatation or paradoxical interventricular septal motion. The results of mid-term follow up after balloon dilatation of the pulmonary valve are encouraging. The degree of pulmonary regurgitation is increasing with time. Longer term follow-up studies should be undertaken to evaluate the significance of residual pulmonary regurgitation.
