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.

Objectives: The aim of this study was to determine the mechanisms and effectiveness of pulmonary antrum radial-linear (PAR) ablation in comparison with pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (AF) after a long-term follow-up. Background: The one-year follow up data suggested that PAR ablation appeared to have a better outcome over the conventional PVI for paroxysmal AF. Methods: The enrollment occurred between March, 2011, and August, 2011, with the last follow-up in May, 2014. A total of 133 patients with documented paroxysmal AF were enrolled from 5 centers and randomized to PAR group or PVI group. Event ECG recorder and Holter monitoring were conductedduring the follow-up for all patients. Results: The average procedure time was 151±23 min in PAR group and 178±43 min in PVI group ( P <0.001). The average fluoroscopy time was 21±7 min in PAR group and 27±11 min in PVI group ( P= 0.002). AF triggering foci were eliminated in 59 patients (89.4%) in PAR group, whereas, only 4 patients (6.0%) in PVI group (P<0.001).At median 36 (37-35) months of follow-up after single ablation procedure, 43 of 66 patients in PAR group (65%) and 28 of 67 patients in PVI group (42%) had no recurrence of AF off antiarrhythmic drug (AAD) (P=0.007); and 47 of 66 patients in PAR group (71%) and 32 of 67 patients in PVI group (48%) had no recurrence of AF with AAD (P=0.006). At the last follow-up, the burden of AF was significantly lower in PAR group than in PVI group (0.9% ± 2.3% vs 4.9% ± 9.9%;90th percentile, 5.5% vs 19.6%; P=0.008). No major adverse event (death, stroke, PV stenosis) was observed in all the patients except one case of pericardial tamponade. Conclusions: PAR ablation is a simple, safe, and effective strategy for the treatment of paroxysmal AF with better long-term outcome than PVI. PAR ablation might exhibit the beneficial effect on AF management through multiple mechanisms. Registration: ChiCTR-TRC-11001191

Echocardiographic Findings

Data on long-term follow-up for closure of so-called secundum type“ atrial septal defects within the oval fossa using recently developed devices are limited, and results focused on presence of residual shunting. The purpose of our study was to report the experience from a single center establishing the effectiveness of transcatheter closure in patients with various types of defect other than those located centrally within the oval fossa.A total of 72 patients was included in this study. On transesophageal echocardiography, the size of the defects varied from 6 to 18 mm, with estimation of the stretched diameter from 11 to 21 mm. The ratio of stretched diameter to the extent of the residual septum ranged from 0.28 to 0.54. Mean follow-up was 30.5+ 7.4 months, with a range from 13 to 42 months. The rate of closure using devices with diameters from 28 to 40 mm increased from 80% immediately after implantation to 93% in the 57 patients examined 24 months after implantation. For further analysis, we compared the 44 patients with a solitary, centrally located, defect to 28 having morphological variations, including superiorly located defects with deficient superior and aortic rims, multifenestrated and aneurysmal defects, or isolated additional defects. There was no incidence of formation of thrombus, sustained atrial arrhythmia, or infective endocarditis. Residual shunting was not influenced by location or morphology of the defects, but increased with size, stretched diameter, and the ratio of pulmonary to systemic flows. Serial transthoracic echocardiographic findings revealed malposition of one right-sided superior arm of the device in 8 patients, while protrusion of one leftsided arm onto the right atrial aspect was observed in 3 patients. Fluoroscopy showed fatigue fracture of a single arm in 7 patients (9.7%) within the first 6 months after implantation.These results demonstrate that transcatheter closure with the non self-centering double umbrella device was effective and safe on medium-term follow-up, and could be extended to defects within the oval fossa having various morphologies. Residual shunting resolved with time, and was not related to either morphology or the position of the device.

The aim of this prospective observational study was to assess efficacy and safety of the ablation procedure in patients with low LV ejection fraction (LVEF) and ventricular tachyarrhythmias originated from right ventricular outflow tract (RVOT) during long-term follow up. Fifty four consecutive patients with symptomatic premature ventricular complexes (PVC) or ventricular tachycardias (VT) with left bundle branch block (LBBB) pattern, inferior axis morphology and transition zone predominantly in V3-V4 were included in this study. The patients were followed up during 36 months after ablation procedure. The mean follow up period was 42.26 months. The long-term efficacy after one ablation procedure was 94.4% (51 patients) and after redo procedures - 98.1 % (53 patients). The LVEF increased from 422 at baseline to 565% after 36 months of follow up (p = 0.001). Radiofrequency catheter ablation in patients with low LVEF and ventricular tachyarrhythmias originated from RVOT is a safe and highly effective treatment during long-term follow up.

The Stability

The long-term outcome of detachable coil embolization of cerebral aneurysms is still unknown. The purpose of this study was to evaluate the stability of the anatomic occlusion of aneurysms treated with the Cook detachable coil system and assess the rate of recanalization and recurrence. A study involving 250 patients with 271 ruptured aneurysms treated with the Cook detachable system between January 1997 and September 2003 who subsequently underwent six month, one year and two year follow-up angiography were enrolled in the study. Angiographic findings were reviewed to determine the percentage of aneurysm occlusion. Long-term follow-up angiograms (at two years) demonstrated complete occlusion in 75% of cases, and subtotal occlusion in 25% of cases. Overall morbidity was 7.3%, aneurysm recurrence 3.2%, and aneurysm re-treatment 3.2%. Recurrent subarachnoid hemorrhage occurred in only one patient. Angiographic follow-up demonstrated the stability and durability of treatment with the Cook detachable coil system.
