انفاندیبول 27 بیمار (60%) به مدت شش ماه تحت دریافت ایندرال قرار گرفتند و 18 بیمار
(40%) ایندرال نگرفتند. در این دو گروه هم بعد از بالن گرادیان به صورت معنی‌داری
افت کرد (0001/0&lt;/span&gt;&lt;span style=&quot;font-size: 7pt&quot;&gt;P&lt;&lt;/span&gt;&lt;span style=&quot;font-size: 10pt&quot;&gt;). در گروه دریافت کننده ایندرال سیر نزولی دایمی و شدیدتر بود.

در ناحیه انفاندیبول متعاقب بالن والولوپلاستی پولمونر به مرور زمان کاهش پیدا می‌کند.
تجویز ایندرال به تسریع این روند کمک می‌کند.&lt;/span&gt;&lt;/p&gt;

&lt;!--stripped--&gt; &lt;strong&gt;Background&lt;/strong&gt;&lt;strong&gt;:&lt;/strong&gt; Isolated
pulmonary valve stenosis represents 8-10% of congenital cardiac anomalies. This study was performed to
evaluate the late outcomes of Balloon Pulmonary Valvuloplasty (BPV) in children with residual
infundibular stenosis.&lt;br&gt;&lt;strong&gt;Methods&lt;/strong&gt; &lt;strong&gt;:&lt;/strong&gt; Seventy-eight patients underwent BPV
in Rajaee Heart Center in Tehran Iran, from
2008-2010.
The patients were divided into two groups: with and without infundibular
stenosis. The group with infundibular stenosis was subdivided into two groups:
with and without propranolol administration. Gradient measurement follow-ups by
Doppler echocardiography were done on the first day and 1, 3, 6 and 12 months afterwards.&lt;br&gt;&lt;strong&gt;Results:&lt;/strong&gt; Thirty five (44.9%) patients were male and
43 (55.1%)
were female. The mean age of participants was 4.29±3.5 years and the mean weight 16.18±8.8
kg 33 patients (43%) did not show residual infundibular stenosis but 45 (57%) did so in the
evaluations. There were no significant differences between the two groups
regarding age, weight, sex, kind of balloon valvuplasty, balloon to body
surface area ratio and pulmonary regurgitation (PR). Propranolol was administered to 27
(60%) patients with residual stenosis for six
months but 18 (40%) did not receive the medication. In both groups, the gradient
significantly decreased immediately after BPV
(P&lt;0.0001). In the propranolol group a constant
decrease in residual gradient was seen. There was a significant relationship
between balloon to body surface area ratio (387±94mm&lt;sup&gt;2&lt;/sup&gt;/m&lt;sup&gt;2&lt;/sup&gt;) with moderate to severe PR (P&lt;0.015).&lt;br&gt;&lt;strong&gt;Conclusion:&lt;/strong&gt; BPV is a safe and effective procedure
to treat PS. Residual infundibular gradient after BPV decreases over time and
propranolol helps decrease the gradient.&lt;/p&gt;
