Successful treatment of patent ductus arteriosus accompanying right-sided aortic arch and aberrant left subclavian artery: a case report

Abstract

Background

The coexistence of a right-sided aortic arch (RAA), an aberrant left subclavian artery (ALSA), and a patent ductus arteriosus (PDA) is a rarely seen vascular ring anomaly. There is currently no general guideline consensus on the management and follow-up of this congenital defect, posing a challenge to the clinicians. At this point, the heart team plays a critical role in the management of the disease.

Case summary

In the present case, a 25-year-old male patient was presented to the outpatient clinic with dyspnoea and fatigue. A transthoracic echocardiography revealed PDA with a left-to-right shunt. To evaluate the anatomy thoroughly, a thoracic computed tomographic angiography was performed and showed PDA accompanying ALSA and RAA. The patient was evaluated by the Heart Team, and a percutaneous closure of PDA was recommended due to signs of left ventricular volume overload. The closure was successfully performed with Amplatzer vascular plug II. At follow-up, the patient was free of symptoms.

Discussion

Clinicians should be aware of the potential concomitant lesions during the diagnostic work-up. In selected patients, percutaneous closure of PDA may be the first-line therapy in experienced centres.
