Abstract

Balloon pulmonary valvoplasty was performed in a patient with congenitally corrected transposition, aged 28 years, who had already undergone surgical closure of a ventricular septal defect and implantation of a conduit between the pulmonary arteries and the right-sided morphologically left ventricle. The patient developed stenosis of the conduit 22 years after the procedure as confirmed by cardiac catheterization and angiocardiography, which also showed stenosis of the native pulmonary valve. A balloon valvoplasty of the native valve was carried out with improvement of the gradient from the ventricle to the pulmonary arteries. The patient developed complete heart block immediately after the procedure, which reverted to first degree block in one week and to the previous cardiac rhythm within 21 days.
