Figure 3. In a 19-month-old boy weighing 10 kg, a 3-mm type A “slow tapering” patent ductus arteriosus was closed using a 5-7 Occlutech Duct Occluder standard shank. The thick arrow shows bulging of the aortic disc, probably due to excessive oversizing. Note the screw pin deformation (thin arrow), which was related to the forced entry of the device in an incompatible delivery system after multiple attempts due to the lack of a dedicated delivery system at the time.
All 18 patients were discharged 24 hours following the pro- cedure. The following day, chest x-rays (anteroposterior and lateral) and Doppler echocardiography were obtained before discharge. Special attention was paid to residual shunts and left pulmonary or aortic isthmic obstruction. Urinalysis was performed only in cases of residual shunting. Patients were scheduled for cardiology consultation and echocardiography at 10 days and at 1, 3, 6, and 12 months.
Statistical Analysis
Results are expressed as percentages and median values.
Results
The median age of the 18 patients was 23.5 months (range, 6–180 months), and median weight was 11
kg (range, 6–54 kg). All patients had isolated PDAs. Table 2 summarizes the basic characteristics of the pa- tients and procedure-related parameters according to PDA morphology. The PDA shape was type A “fast tapering” in seven patients (40%), type A “slow taper- ing” in nine patients (50%), type E in one patient, and type D in one patient. The narrowest PDA diameter ranged from 2 to 5 mm (median, 3 mm). Median pro- cedure time was 55 min (range, 35–105 min), and me- dian uoroscopy time was 9.19 min (range, 3–29.57 min). Device diameters (aortic end) ranged from 3.5 to 6 mm (median, 5 mm); standard device variants were used in 13 patients, and long devices were used in ve patients. The median follow-up period was 12
