Thoracic endovascular repair technique for the treatment of patent ductus arteriosus in an elderly patient: A case report

Case report: Thoracic endovascular aortic repair using a non-touch exclusion technique with a custom-made device for the treatment of a large patent ductus arteriosus

Patent ductus arteriosus (PDA) is a common congenital heart disease affecting roughly one in every 2,000 term births. Although most of the patients are diagnosed and treated during childhood, few cases may persist into adulthood. We presented a 27-year-old male patient with a 20.2 mm diameter PDA who was referred to our hospital with progressive fatigue and exertional dyspnea. Given the potential complications, usual techniques such as coil occlusion and duct occluders were deemed inappropriate for this patient. Thoracic endovascular aortic repair (TEVAR) using a non-touch exclusion technique was successfully performed for this patient. The patient was discharged with no major post-surgical complications. TEVAR could be a new, safe, and effective alternative treatment to other transcatheter procedures for complicated PDAs in some patients.

Patent Ductus Arteriosus Exclusion Technique Using Thoracic Endovascular Aortic Repair

A large patent ductus arteriosus is an uncommon discovery in an adult. A 2.7-cm patent ductus arteriosus was found in a 31-year-old man with heart failure symptoms. Owing to the size, an occluder device failed to prevent left-to-right shunting, and consideration was given for alternatives to percutaneous closure, including traditional open repair vs thoracic endovascular aortic repair (TEVAR). After a left carotid-subclavian artery bypass was performed, the patient underwent a zone 2 deployment of TEVAR graft. TEVAR exclusion is a useful technique in adults, particularly in the setting of a large or calcified ductus.

Transcatheter Closure of Patent Ductus Arteriosus in Elderly Patients: Initial and One-Year Follow-Up Results-Do We Have the Proper Device?

Objectives

Patent ductus arteriosus (PDA) in elderly patients is an uncommon anomaly, and the duct itself is often calcified and fragile; therefore, transcatheter closure is more difficult. The aim is to analyse periprocedural and one-year follow-up results of transcatheter closure of PDA in such patients. Methods and results. Retrospective analysis of 33 elective patients aged ≥55 years (median 63; 56-85; 29 women), in whom PDA was closed percutaneously between 2002 and 2018 in two tertiary centres. All but three patients were symptomatic, with most in NYHA II (n = 14) and III (n = 11) class; pulmonary hypertension (n = 22), arterial hypertension (n = 22), duct calcifications (n = 17), atrial fibrillation (n = 15), significant mitral regurgitation (n = 5), and decompensated renal failure (n = 2) were observed. Different devices were applied depending on PDA morphology; nitinol wire mesh occluders with symmetrical articulating discs have been the most used in recent years (n = 11). Follow-up was conducted at an outpatient clinic (28/33 patients). The procedure was successful in all patients. There was one embolisation, followed by implantation of a larger device. No major complications were noted. A small residual shunt was present in echocardiography in one patient after one year. NYHA class improved in all but two patients (with multiple comorbidities).

Conclusions

Transcatheter PDA closure in elderly patients is safe and efficient with a high complete closure rate and few complications. Amplatzer duct occluder type II is an attractive device in such patients.
