CASTRO B., Abdón; YONG P., Bernal; YONG R., Adrián  and  ZUNIGA V., Marcela. Efectividad de la valvuloplastia pulmonar percutánea en el tratamiento de la estenosis pulmonar valvular moderada y severa en el Hospital Nacional de Niños, a los 10 años de practicar el procedimiento. Rev. costarric. cardiol [online]. 2003, vol.5, n.3, pp.11-14. ISSN 1409-4142.

Pulmonary valvuloplasty is nowadays the treatment of choice for moderate to severe valvular pulmonary stenosis. In 1992, Kan introduced the technic and today it is a procedure easy to perform, cheap and with excellent results. A retrospective study was carried out in the Hospital Nacional de Niños in San José, Costa Rica in order to analyze their situation. A total of 98 cases with pulmonary valvuloplasty were found with ages from 4 days to 24 years.. There was no sex predominance. Forty one children were under one year of age and 56 were older than one year. The most frequent age when the procedure was done was at three years. The transvalvular gradients varied from 31 to 170 mmHg in pre-dilation and 0 to 96 mmHg in post dilation of the pulmonary valve. No deaths were reported and the most common complications were one case of asystole, one case of atrial flutter and one case of supraventricular tachycardia. In conclusion, pulmonary valvuloplasty is a low risk procedure with satisfactory results.
