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) refers to an abnormal channel between the pleural space and the bronchial tree. It is a potentially fatal postoperative complication after pulmonary resection and a complex challenge for thoracic surgeons because many patients with BPF ultimately develop refractory empyema, which is difficult to manage and has a major impact on quality of life and survival. Therefore, an operative intervention combined with conservative and endoscopic therapies may be required to control infection completely, to occlude BPF, and to obliterate the empyema cavity during treatment periods. Case presentation Two patients who suffered from BPF complicated with chronic empyema after lobectomy were treated in other hospitals for a long time and did not recover. In our department, we performed staged surgery and creatively combined an Amplatzer Septal Occluder (ASO) device (AGA Medical Corp, Golden Valley, MN, USA) with pedicled muscle flap transposition. First, open-window thoracostomy (OWT), or effective drainage, was performed according to the degree of contamination in the empyema cavity after the local infection was controlled. Second, Amplatzer device implantation and pedicled muscle flap transposition was performed at the same time, which achieved the purpose of obliterating the infection, closing the fistula, and tamponading the residual cavity. The patients recovered without complications and were discharged with short hospitalization stays. Conclusions We believe that the union of the Amplatzer device and pedicle muscle flap transposition seems to be a safe and effective treatment for BPF with chronic empyema and can shorten the length of the related hospital stay.

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.

A total of 6 patients (5 men and 1 woman, aged 66.67±6.19 years [mean ± SD]) had bronchopleural fistulas sealed using the SFM for AD implantation. Results: Closure was successfully performed in all 6 patients with the SFM, and the average duration of operation was 16.17 minutes (16.17±4.67 minutes [mean ± SD]). Five patients achieved complete occlusion after the operation, and 1 patient who had multiple fistulas did not. No patients died due to operation complications and 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 sealing, and patient symptoms significantly improved after sealing.

A case of a severe paravalvular mechanical mitral prosthesis leak in a high-risk patient that underwent previously 4 mitral valve surgeries is described. An Amulet-Amplatzer device was correctly implanted on the left atrial appendage, with the temptative to close also the contiguous severe leak. A residual moderate paravalvular leak caused acute hemolysis with severe renal failure requiring hemodialysis. The transesophageal echocardiogram is crucial in localizing and defining the extent of the paravalvular leak. It is not clear if the hemolysis was precipitated by the evolution of the disease or by the residual regurgitation after Amulet device deployment. Certainly, given the intricacy of the procedure the results might be limited also for highly expert operators. To our knowledge, this is the first case reporting the use of the Amulet-Amplatzer device for paravalvular leak closure.

AbstractTranscatheter atrial septal defect (ASD) device closure has emerged as a safe and effective alternative procedure for surgical ASD repair. However, ASD device malposition and embolization has been reported with an incidence of 0.5 to 1.1%. We report here a case of a 32-year-old male, who presented to the hospital 5 months after ASD device closure for routine follow-up. This case reports highlights the significance of transesophageal echocardiography (TEE) evaluation in successful surgical retrieval of a dislodged ASD Amplatzer device.
