[Changes in intracardiac hemodynamics after percutaneous catheter balloon valvuloplasty in different types of valvular stenosis of the pulmonary artery].
Percutaneous catheter balloon valvuloplasty was carried out in 75 patients with valvular pulmonary stenosis (VPS), whose ages ranged from 18 months to 38 years. In 40 of them (53.3%) VPS was complicated by infundibular stenosis of the right ventricle. After percutaneous catheter balloon valvuloplasty 13 patients received out-patient treatment with beta-adrenergic blocking agents in doses of 20 to 120 mg/24 hours. Control examination in periods of 6 months to 2 years after the operation was conducted in 35 patients among whom 10 patients had been given beta-adrenergic blocking agents in the postoperative period. A stable reduction of the right ventricle-pulmonary artery (RV-PA) gradient and positive dynamics of the cardiac volume indices were recorded in 25 patients after correction of isolated VPS and in 6 patients after percutaneous catheter balloon valvuloplasty and treatment with beta-adrenergic blocking agents. The residual RV-PA gradient in 4 patients after treatment with beta-adrenergic blocking agents remained within a range of 30 mm Hg. Percutaneous catheter balloon valvuloplasty is an effective method for the correlation of isolated VPS. Coexistence of VPS with infundibular right-ventricular stenosis is not a contraindication for the use of this method for correcting the anomaly. In such a case the roentgenosurgical intervention should be supplemented by treatment with beta-adrenergic blocking agents in individual doses.
