“…3). The optimum balloon diameter should be between 1.2 and 1.3 times the size of the pulmonary valve annulus for singleballoon dilation (7,8). Lower balloon-to- Balloon dilatation of pulmonary valve produces long term gratifying results, and re-stenosis rates are extremely low except in neonates.…”

SUMMARYCatheter based techniques, whether palliative or corrective, are now the accepted therapy for many congenital cardiac defects. The spectrum of transcatheter procedures has rapidly increased over the last three decades with improving technical skills of the operator combined with sound anatomic and hemodynamic understanding of the patient's condition and the choice of appropriate equipments. In today's pediatric cardiology practice many congenital defects can be treated with balloons used for dilatation of the stenotic valves or vessels combined with the use of various stents for prevention of recurrence of stenosis, some defects can be closed with various devices or coils. With rapidly growing concepts, innovative hardware improvements, development and expertise of interventionalists and surgeons, the application of catheter interventions and hybrid procedures are becoming standard practice. Some of these are practiced in India. Many of them at present are not being practiced in India due to non availability of hardware and the prohibitive cost.

Eight-six children (aged 20 days to 14 years, 20 under age 1 year) underwent 94 percutaneous balloon valvuloplasty for pulmonary valve stenosis. The patients were divided into three groups: typical pulmonary valve stenosis (71), pulmonary valve dysplasia (9), and residual stenosis after surgical valvotomy for pulmonary atresia with intact ventricular septum (PAIS) (6). Each of the three groups was divided into two subgroups. In the early cases, balloon catheters with diameter 10-20% exceeding pulmonary valve annulus were used and the drop of the gradient was 39.5%. In the later cases, balloon diameters 30-40% greater than the valve anulus or double balloons were used and a drop of 66.7% in the RV-PA pressure gradient was achieved. The dilation in patients with dysplastic valve and residual stenosis after surgical valvotomy for PAIS was less effective. Doppler echocardiography was the technique used to evaluate residual gradient. Six months to 4 years follow-up demonstrated a persistent decrease of the valve gradient.

To alleviate large fixed right ventricular (RV) outflow gradients, percutaneous balloon dilatation of pulmonic stenosis (PS) was performed in 38 patients with mean age of 14 +/- 14 years (median: 9 years, age range: 9 months to 63 years). There were 21 males and 17 females. Thirty-four patients had typical PS (5 of them also having other complex congenital cardiac anomalies, while 13 additional patients had a patent foramen ovale); 2 further subjects had subpulmonic, and 2 dysplastic pulmonary valvular obstructions. Sixteen patients were in the New York Heart Association (NYHA) Class I, 15 in Class II, 6 in Class III, and 1 in Class IV. Electrocardiographic (ECG) evidence of right ventricular hypertrophy (RVH) was present in 29 patients (76%); 3 patients had right bundle branch block (RBBB). For the entire group, there was a marked decrease in the mean systolic transpulmonic gradient in the immediate post-valvuloplasty period (from 97 +/- 43 to 26 +/- 17 mmHg; P < 0.0001). One patient expired 8 hours post-valvuloplasty (he was in the NYHA Class IV, and had severe RV failure). No other cardiovascular complications were encountered; the median hospital stay was 3 days (range: 1-10 days). At an 8-month follow-up, 12 patients who were reevaluated invasively had a median transpulmonic gradient of 27 mmHg (range: 5-92 mmHg) as compared to their pre-valvuloplasty values of 84 mmHg (range: 49-142 mmHg; P < 0.004).(ABSTRACT TRUNCATED AT 250 WORDS)
