Case Report: A new therapeutic option for a rare patent ductus arteriosus child complicated with pulmonary artery aneurysm due to infectious endocarditis.

Patent ductus arteriosus (PDA) is one of the most common forms of congenital heart disease (CHD). Infectious endocarditis (IE) is a rare but serious complication of PDA. PDA combined with pulmonary artery aneurysm (PAA) due to IE is rare in children. In this report, we report a rare pediatric PDA case, complicated with PAA due to IE. Transcatheter closure of PDA without the surgical intervention of PAA was performed, with a favorable prognosis.
