Percutaneous Closure of Patent Ductus Arteriosus in an Asymptomatic Adult

TL;DRAbstract

he ductus arteriosus allows deoxygenated blood from the right ventricle through the descending aorta and to the placenta in the fetal period. Functional and anatomical closure is complete by several weeks after birth. Patients with ductus-dependent physiology generally have advanced congenital malformations and require surgi-cal intervention early in life. However, some patients will present as adults with a patent ductus arteriosus (PDA). We describe a 43-year-old woman who was found to have a PDA during evaluation for a precordial murmur, and she underwent successful percutaneous closure.Case RepoRtA 43-year-old woman with mild systemic hypertension was referred after a precordial murmur was detected by her primary physician. Her only complaint was occasional pal-pitations. Her systemic blood pressure was well controlled on lisinopril 10 mg daily. A continuous murmur was pres-ent in the left first and second intercostal spaces. Echocardiogram revealed normal-sized cardiac cham-bers a
