Abstract Background: Up to now, transcatheter closure of patent ductus arteriosus(PDA) without severe pulmonary artery hypertension (PAH) has been well established and accepted in clinical practice. However, in PDA patients with severe PAH, transcatheter closure still remains a challenge, regardless of the tremendous advancement in devices and techniques.Methods: We reviewed the records of PDA patients who underwent transcatheter device closure though single femoral venous approach between January 2005 and December 2018. Severe PAH was defined as systolic pulmonary artery pressure (SPAP) measured by a catheter >70mmHg, excluding irreversible severe PAH assessed by trial occlusion. Propensity score matching was used to assemble a cohort of patients with similar baseline characteristics. Results: A total of 29 patients were in severe PAH (SPAH) group after excluding 2 for failing to the trial occlusion, and 468 in non-severe PAH(non-SPAH) group. After matching, 25 patients were in SPAH group, and 39 in non-SPAH group, without any significant difference in baseline characteristics. The median follow-up periods were 57 and 44 months for groups, respectively. No significant difference was noted in the rates of cumulative adverse events in the 2 groups (p=0.208). No poor effects in left ventricular function and residual shunt evaluated by transthoracic echocardiography(TTE) in SPAH group were detected in the short- and long-term follow-up.Conclusion: In the patients with PDA associated with reversible severe PAH, compared to non-severe PAH, transcatheter closure through single venous approach has comparable adverse events rates and successful closure rate, with equivalent results of TTE examination at the short- and long-term follow-up.

We evaluated long-term angiographical follow-up of cerebral aneurysms treated with detachable platinum coils with special reference to the long-term morphological outcomes of incompletely obliterated aneurysms. Serial long-term follow-up cerebral angiograms (>1 year) were obtained in 47 cases out of 134 cases treated with GDCs or IDCs from 1994 to 1999. In 47 patients, intial angiographical results demonstrated ten complete aneurysmal occlusion, seven aneurysms with a small neck remnant, twenty aneurysms with body filling and ten aneurysms with both of neck remnant and body filling. In the ten completely obliterated aneurysms, follow-up angiograms revealed no aneurysmal recanalization. In seven aneurysms with neck remnant, three remained unchanged, four showed enlargement of contrast filling in the part of the neck of the aneurysm. In twenty aneurysms with body filling, five had developed into complete obliteration, three remained unchanged, 11 had recanalization, and one aneurysm displayed regrowth. In ten aneurysms with both of neck remnant and body filling, two remained unchanged, five had recanalization, and three aneurysms displayed regrowth. Long-term angiographical follow-up results are less satisfactory in cases involving incompletely obliterated lesions. A higher incidence of recanalizations were promoted in cases with neck remnant and/or body filling. Strict follow-up angiography is mandatory when a complete obliteration is not achieved.

This study reviewed the short-term outcome of transcatheter closure of the defects within the oval fossa using an Amplatzer® Septal Occluder. From January 1997 to December 2000, 210 patients with defects within the oval fossa underwent successful transcatheter closure. We reviewed a total of 190 patients with left-to-right shunts, assessing the patients for possible complications and the presence of residual shunts using transthoracic echocardiogram at 24 h, 1 month, 3 months and one year. Their median age was 10 years, with a range from 2 to 64 years, and their median weight was 23.9 kg, with a range from 8.9 to 79 kg. In 5 patients, a patent arterial duct was closed, and in 2 pulmonary balloon valvoplasty performed, at the same sitting. The median size of the Amplatzer® device used was 20 mm, with a range from 9 to 36 mm. The median times for the procedure and fluoroscopy were 95 min, with a range from 30 to 210 min, and 18.4 min, with a range from 5 to 144 min, respectively. Mean follow-up was 20.8 ± 12.4 months. Complete occlusion was obtained in 168 of 190 (88%) patients at 24 h, 128 of 133 (96.2%) at 3 months, and 103 of 104 (99%) at one year. Complications occurred in 4 (2.1%) patients. In one, the device became detached, in the second the device embolized into the right ventricular outflow tract, the lower end of the device straddled in the third, and the final patient had significant bleeding from the site of venupuncture. There were no major complications noted on follow-up. We conclude that transcatheter closure of defects within the oval fossa using the Amplatzer® Septal Occluder is safe and effective. Long-term follow-up is required, nonetheless, before it is recommended as a standard procedure.
