Atrial Septal Defect Occluder Device Embolization: Experience of a Tertiary Care Cardiac Center

Background: Percutaneous device closure of atrial septal defect (ASD) has become an increasingly popular procedure as it offers several advantages. However, it is associated with infrequent, but life?threatening complications such as device embolization. Objective: To analyze the risk factors, common sites of embolization, associated complications, timing of embolization, and the treatment executed. Settings and Design: A retrospective study was performed at a tertiary referral center for cardiac services. Material and Methods: Pre?procedure, intra?procedure, and post?procedure data of patients whose ASD device embolized was collected retrospectively and analyzed for risk factors, common sites of embolization, associated complications, timing of embolization, and the treatment executed. Results: Thirty devices were embolized, out of which 13 were retrieved percutaneously in the Catheter laboratory, whereas 17 patients underwent surgery. Fourteen patients had an unfavorable septal morphology for device closure. Ten devices were embolized in the catheter laboratory, five in the intensive care unit, and two in the ward. The devices were embolized to almost all chambers of the heart and great vessels. One patient had an inferior vena cava rim tear while attempting percutaneous retrieval. One patient required a short period of total circulatory arrest (TCA) for retrieval of the device from ascending aorta, while another required a lateral position for retrieval from descending aorta. One patient required re?exploration for bleeding, while another had an air embolism and succumbed. Conclusions: Once embolization occurs, the risks associated increase manifold. Most of the surgical extractions are uneventful; however, there could be certain complications that may need repair of valvular apparatus, the institution of TCA, or the need for the lateral position. Air embolization though very rare can occur which could be fatal.

Percutaneous ASD Closure Requiring Emergency Surgical Removal of Embolized Cardiac Occluder Devices

Introduction: Atrial septal defect (ASD), ventricular septaldefect (VSD), patent ductus arteriosus (PDA) are mostcommon congenital acyanotic heart diseases. Surgery isthe gold standard treatment for these defects. Percutaneousdevice closure is now getting popular for closure of thesedefects (Ostium Secundum ASD, PDA, muscular VSD).Device dislodgement, migration and embolization is a causeof failure in this procedure. For this emergency surgicalretrieval of migrated device becomes necessary at times.Here two different scenarios of failed device closure of ASDare presented who required emergency surgical retrieval ofdevice.Case report: In the first case the device got embolized intothe main pulmonary artery which was retrieved surgicallyand his post-operative period was uneventful. In the secondcase the device got embolized into right ventricle. Surgicallythe device was retrieved but post operatively the patient wasfound to have CVA from which she recovered gradually anddischarged.Conclusion: Proper assessment of defect size and rim aroundthe defect is necessary. Devices of all sizes should be availablewith the team doing the procedure. During implantation incase of unsatisfactory device position it should be retrievedand elective surgical closure should be planned. Surgeonsshould be kept in backup in all catheter based procedure.

Successful Percutaneous Retrieval of Embolised Septal Occluder Device and Device Closure of Atrial Septal Defect in Combined Procedure

Transcatheter device closure is the treatment of choice in patients with secundum atrial septal defects with adequate rims. It is technically safe, feasible and has the obvious advantage of being a nonsurgical technique. Patient is free from the scar especially young, unmarried females. It is not free of complications. Device embolization and arrhythmias are the major complications. Embolised device can cause hemodynamic compromise by obstructing the blood flow if it gets embolised in pulmonary artery. We report a case of 24 year old female, taken for device closure of atrial septal defect. Device gets embolised in pulmonary artery causing hemodynamic compromise by causing obstruction to blood flow. This embolised device was successfully retrieved percutaneously. The atrial septal defect was closed with one size larger device, in the same sitting. Patient is asymptomatic and is free from any scar.

The Operative Management of Embolized Septal Occluder at Ascending Aorta / 계명의대학술지

Percutaneous device closure of secundum atrial septal defect (ASD) has become a definite therapy in selected patients. However the more transcatheter device was implanted, the more complication was developed. Especially, the device embolization remains a major complication requiring immediate intervention. We report a case of a displaced ASD occluder in the ascending aorta. We were successfully removed the device through a total circulatory arrest and closed the ASD.

Emergent Surgical Intervention for Embolization of Atrial Septal Defect Closure Device

The percutaneous transcatheter closure of secundum atrial septal defect has recently become an increasingly widespread alternative to surgical closure in many centers. Although immediate, short, and intermediate term results of percutaneous transcatheter septal closure are promising, the procedure is not free from inherent complications that could be lethal. We report a case of device embolization necessitating emergent surgical retrieval.
