چکیده
OBJECTIVES To describe the characteristics and outcome of children with an isolated silent patent ductus arteriosus (SPDA), with comparison to non-silent ducts. PATIENTS AND METHODS Between 1999 and 2004, all consecutive cases of isolated silent and non-silent-patent ductus were recorded at the National Register of Pediatric and Congenital Heart Disease, Lebanese Society of Cardiology. Patients with a SPDA were followed clinically and by Doppler echocardiography while all non-SPDA were percutaneously or surgically closed. RESULTS Twenty-four cases of isolated SPDA and 50 cases of isolated non-SPDA ducts were recorded. Male sex was significantly predominant in the silent group (70%). First-cousin consanguinity rates were not different between both groups, with 20.4% for the silent group versus 22% for the non-silent group. Down's syndrome was associated in three cases of SPDA. No cases of endocarditis were noted during a mean follow-up of 33.3 months. Four patients with a SPDA experienced spontaneous closure at the age of 25, 30, 36 and 58 months. CONCLUSION SPDA is a relatively benign disease. The risk of endocarditis cannot be totally ignored, but the systematic closure of the SPDA is not warranted. Larger series and longer follow-up are needed in order to draw conclusions. Spontaneous closure occurred in four patients with SPDA.

Patent ductus arteriosus (PDA) is a persistent patency of a vessel normally present in the fetus that connects the pulmonary arterial system to the aorta. The ductus arteriosus fails to close at birth when breathing commences and placental blood circulation is removed. Closure of the ductus arteriosus arises in response to decline pulmonary vascular resistance and increased systemic vascular re...
