Abstract Ductus arteriosus is a physiological structure if not closed after birth, may lead to many complications. Today, trans-catheter closure of patent ductus arteriosus with Occluder devices is the preferred method. Surgical ligation is used only in certain cases such as large symptomatic patent ductus arteriosus in very small infants and premature babies; unfavourable structure of the duct or economic considerations. In this article, we described haemodynamic and morphological characteristics of five patients with large patent ductus arteriosus which were occluded with Amplatzer device. From 23 January, 2010 to 31 July, 2018, five patients referred to our clinic with large patent ductus arteriosus and pulmonary arterial hypertension for further evaluation. After assessing them with various diagnostic methods, we decided to close defect with ventricular septal defect Occluder device. Patients aged 21–44 years and one of them was male. Ductus closure was successfully done with ventricular septal defect Occluder device. Closure was successful for all of them but in one case, whose device was embolized to pulmonary artery after 24 hr and he underwent surgery. Trans-catheter closure of large patent ductus arteriosus in adult patients with pulmonary hypertension is feasible. Despite the fact that complications may occur even with the most experienced hands, the ‘double disk’ Amplatzer ventricular septal defect muscular Occluder could be advantageous in this setting.

Abstract Background Bronchopleural fistula (BPF) is a relatively rare complication after various types of pulmonary resection. The double-sided mushroom-shaped occluder (Amplatzer device, AD) has been gradually used for BPF blocking due to its reliable blocking effect. We have improved the existing AD implantation methods to facilitate clinical use and named the new approach Sheath-free method (SFM). The aim of the present report was to explore the reliability and advantages of the SFM in AD implantation. Methods We improved the existing implantation methods by abandoning the sheath of the AD and using the working channel of the bronchoscope to directly store or release the AD without general anesthesia, rigid bronchoscopy, fluoroscopy, or bronchography. A total of 6 patients (5 men and 1 woman, aged 66.67 ± 6.19 years [mean ± SD]) had BPF blocking and underwent the SFM in AD implantation. Results AD implantation was successfully performed in all 6 patients with the SFM, 4 persons had a successful closure of the fistula, one person died after few days and one person did not have a successful closure of the fistula. The average duration of operation was 16.17 min (16.17 ± 4.67 min [mean ± SD]). No patients died due to operation complications or BPF recurrence. The average follow-up time was 13.2 months (range 10–17 months). Conclusion We observed that the SFM for AD implantation—with accurate device positioning and a clear field of vision—is efficient and convenient. The AD is effective in BPF blocking, and could contribute to significantly improved symptoms of patients.

Abstract Background Inappropriate shocks have been reported in approximately 1/3 of patients with implantable cardiac defibrillators (ICDs). We report an unusual case of inappropriate ICD shocks due to atrial fibrillation (AF) caused by a missed atrial septal defect (ASD) in a patient with a modified Bentall procedure. Case summary A 67-year-old Caucasian male, with an ICD and a history of a modified Bentall procedure 24 years ago, reported to our outpatient clinic with recurrent inappropriate ICD shocks due to episodes of fast AF. The transthoracic echocardiographic exam revealed 2 large aneurysms at the ostia of the coronary arteries. We performed further evaluation with transesophageal echocardiogram (TOE) and computed tomography (CT) angiography. The aneurysms measured on CT were 3.14*2.29 cm on the right ostium and 1.9*0.99 cm on the left. A large secundum-type atrial septal defect (ASD) of 1.5 cm was revealed that was missed in all previous echocardiographic studies. The therapeutic options of surgical closure of the ASD and repair of the aneurysms or a more conservative approach with percutaneous closure of the ASD and closer follow-up were discussed with the patient. The patient declined the surgical option due to high complication risk, and closure of the ASD with an Amplatzer device was performed 3 months later. A 3 -year Follow-up was uneventful. Conclusion It is of major importance to comprehensively and thoroughly assess patients before and after a surgical intervention to not miss other treatable conditions preoperatively and complications in the postoperative period.

AbstractObjectiveOur aim was to assess the immediate and short term results of closure of moderate and large patent arterial ducts using the self-expanding and repositionable Amplatzer device.MethodWe attempted closure in 25 patients (10 Females and 15 males) using the Amplatzer occluder. Their median age was 48 months with a range from 8months to 26years and median weight of 14kg with a range from 4.5kg to 48kg. The mean ductal diameter was 4 (S.D 1.51mm). A 6F/7F long sheath was used to deliver the device. Follow up was performed with colour- flow mapping of the pulmonary trunk within 24 hours, at 3 months, and 6 months of closure.ResultsOf the 25 patients, the device was placed successfully in 23. Concurrent angiography showed immediate closure in 12 patients, while 8 had trivial shunting and 3 had mild shunting. Within 24 hours, Doppler examination revealed complete closure in all but three patients, who had a mild residual shunt. Two attempts were unsuccessful. Both these patients underwent successful surgical ligation. All except one patient were discharged on the next day. Of the 23 patients, 15 (65%) have been followed up for 3months, while 8 (35%) have completed 6 months of follow-up. Of the three patients initially with mild residual flow, two had completely closed at 3 months The one remaining patient is yet to be seen at the 3 month follow-up. Thus, at 3 months, all patients studies had shown complete closure.ConclusionAntegrade transcatheter closure using the Amplatzer duct occluder is an efficacious treatment for bigger patent arterial ducts. Long-term follow-up is necessary to show sustained benefits and confirm the absence of side effects.

Aim: To report results of transcatheter occlusion of moderate to large patent arterial ducts, having a minimum diameter above 2.5 mm, with the Amplatzer duct occluder, and to compare these with results achieved using Rashkind or Sideris devices and Cook detachable coils. Design and setting: Retrospective study conducted on intention-to-treat data from a tertiary referral centre. Patients: Since 1989, 116 consecutive patients, 77 females and 39 males, underwent percutaneous closure with several devices. We used the Rashkind double umbrella in 23 patients, the Sideris buttoned device in 39 patients, coils in 17 patients, and the Amplatzer duct occluder in 37 patients. The median age of the patients was 37 months, and the median weight 13 kg. The mean minimum diameter of the duct was 3.8 ± 1.22 mm, with a median of 3.5 mm, and range from 2.5 to 10 mm. Results: Implantation succeeded in all but 9 of the children (92%). The time of fluoroscopy was shorter, and full occlusion was better as judged on angiography, in patients closed using the Amplatzer device, despite closure of larger ducts, than in patients closed using other devices (p < 0.0001, p = 0.0003, and p = 0.0015 for the Rashkind, Sideris, and coils, respectively). Complications included embolisation in 2 patients, and haemolysis in 3 patients. In 12 patients, a second device was inserted because of residual shunting noted during follow-up. Complete occlusion was achieved earlier after implantation (p = 0.0002), and the rate of complete occlusion was better in patients receiving an Amplatzer device (97%, p = 0.024) than in patients undergoing closure with other devices. Conclusion: Transcatheter closure of moderate to large patent arterial ducts using the Amplatzer duct occluder is an effective and safe procedure, providing better results than those achieved using other occluders.
