Abstract:
Objective To investigate the safety and effectiveness of percutaneous balloon pulmonary valvuloplasty (PBPV) in the treatment of pulmonary stenosis (PS). Methods The subjects were 52 patients with PS from 2007 to 2012, including 24 male and 28 female. Their age ranged from 1 year old to 56 year old and mean age was 9.2±7.6 years old. Their body weight ranged from 10 kg to 60 kg and mean weight was 17.3±8.9 kg. All patients were assessed with electrocardiogram (ECG), chest X-ray, right heart catheterization and right ventricular angiagraphy before the procedure. Results All 52 patients received PBPV successfully. Comparing the transvalvular pressure gradient before and after the operation, it decreased from 86.3±27.6 mmHg (1 mmHg=0.133 kPa) to13.8±7.7 mmHg, and statistically difference (P<0.01). Among these patients, one patient occurred ventricular fibrillation and Aspen syndrome (hypoxie-ischemic encephalopathy), one patient occurred respiratory and cardiac arrest, 24 patients occurred transient arrhythmia, one patient had hypotension, one patient had bradycardia and one patient showed desaturation. All these symptoms resolved after appropriate treatment during the PBPV. Two patients had hematoma in the puncture point and 2 patients had reactive infundibular stenosis after PBPV. Conclusions Performing the percutaneous balloon pulmonary valvoplasty on the patients with pulmonary stenosis is safe and effective. PBPV causes less pain and can be used as the preferred treatment for pulmonary stenosis.
