Nickel release after implantation of the Amplatzer occluder.
2003
Background Transcatheter closure of atrial septal defects is a new and less traumatic technique than open heart surgery. In recent years, patients with a patent foramen ovale sustaining potential paradoxical embolism have also become candidates for interventional closure devices. One of the more popular occluding devices is the Amplatzer septal occluder, which, like many other occluders, is made of nitinol. Nitinol-based alloys are widely used in medical products, for example, in orthopedics and orthodontics. However, the clinical use of nitinol, which contains 55% nickel, is still controversial because of concerns about its biocompatibility. Therefore, we examined the systemic nickel relea…
Transcatheter Vs. Surgical Closure of Atrial Septal Defects in Adults
2018
Abstract Percutaneous transcatheter device closure of secundum atrial septal defects (ASD) has now largely replaced surgical closure in most centres. The aim of this study was to compare results of transcatheter and surgical ASD closure in adults in Latvia during the years 2002–2014 and to analyse long-term outcomes of transcatheter closure. We analysed data from 334 patients with secundum ASD who underwent ASD closure in Pauls Stradiņš Clinical University Hospital. Patients were included into device or surgical closure groups. In the device group, three follow-ups were made 1, 6, and 12 months after the procedure. No follow-up data were available for surgical arm patients beyond their hosp…
Catheter-based closure of a large atrial septal defect with inferior rim deficiency using pulmonary vein slide-out assisted implantation technique: a…
2021
Abstract Background Transcatheter approach for large and complex atrial septal defects may represent a therapeutic challenge, particularly when the postero-inferior rim is deficient and floppy. Case summary Here, we describe a successful catheter-based closure of a large (>30 mm) secundum atrial septal defect associated with postero-inferior rim deficiency in a 35-year-old female with congestive heart failure using pulmonary vein slide-out assisted implantation technique. Discussion Inferior–posterior rim deficiency is a well-known risk factor for device instability or embolization. Transcatheter closure may represent a safe and effective alternative to the traditional surgical appro…
