Abstract:
Objective To discuss the hemodynamics and treatment of silent patent ductus arteriosus (PDA) Methods The heart catheterizations were performed in seven silent PDA patients Results The mean pulmonary artery pressure of seven patients was (16?2 4) mm?Hg The mean Qp/Qs was 1 08?0 02 The mean size of the left right shunt was (0 32?0 08) L/min The proportion of left right shunt size in pulmonary blood flow was 0 098?0 024 on average The mean PDA at its narrowest segment was (0 9?0 2) mm We performed neither surgery nor interventional treatment in all patients In 9 5 months follow up (clinical findings, electrocardiography, echocardiography), no atrioventricular chambers enlargement, pulmonary hypertension, infective endoarteritis and infective endocarditis happened Conclusion In silent PDA patients, there is less size of left right shunt and smaller effect on hemodynamics Its treatment with surgical and interventional closure is under discussion
