Authors report their results with transcatheter closure of patent arterial duct during a period of 1 year. Thirty patients underwent the procedure at the mean age of 5.22 yrs (range 5 mos-22.3 yrs) and mean bodyweight of 19.1 kg (range 5.8-73 kg). There were 9 males and 21 females. The diagnosis of the patent arterial duct was established by physical examination and noninvasive techniques. The procedures were attempted in all patients above 5 kg bodyweight with patent arterial duct and normal pulmonary artery pressure, irrespective of the shunt-size. All procedures were performed under general anesthesia in one session with the diagnostic cardiac catheterisation. Transcatheter closure was successful in 29 patients. In one patient the device embolized into the left pulmonary artery, snaring was unsuccessful, surgical closure of the patent duct and removal of the device took place uneventfully. Control aortography 15 minutes after the coil placement showed insignificant residual shunt through the patent duct in 8 patients (27%), while echocardiography at 1 month proved complete closure in all. The patients were followed by noninvasive methods. No mortality was observed. Authors emphasize the low risk and cost-effectiveness of the procedure. They stress the importance of the patients selection. Authors applied the technique for the first time and introduced it to the regular patient-care practice in Hungary.
