ABSTRACT
Balloon pulnounary valvuloplasty is an established method in the treatment of congenital valvular pulmonary stenosis. Balloon valvuloplasty was performed by using one or two balloons in a total of 19 mongrel dogs. Cross sectional area ratio ranging 145-406% was used to compare the relative sizes of the pulmonary annulus the balloon Hemodynamic changes and cardiac damages in single and double balloon groups were analyzed. Survival time of double balloon group was longer than that of single balloon group(P0.05). Major microscopic findings were sloughing of the endotheliu, fibrin deposition, hemorrhage, localized myocardial infarction and so on. In conclusion, double balloon pulmonary valvuloplasty is superior to single balloon technique in survival time and hemodynamics. Therefore, double, balloon technique is recommended for the pulmonary valvuloplasty.
