Abstract:
Objective To explore the value of transthoracic echocardiographic suprasternal view in the diagnosis of the subtype of the patent ductus arteriosus(PDA).Methods Sixty-five cases with PDA were examined by transthoracic echocardiographic suprasternal view and parasternal great artery short axis view respectively before closure therapy.The diameters of both the aotic and pulmonary side were detected,and subtype diagnoses were made.The results were compared with those from digital subtraction angiography (DSA).Results The demonstrated rates of PDA were 100％ on the parasternal great artery short axis and suprasternal views.Of the 65 cases,12 cases,19 cases and 19 cases were the funnel type of PDA checked on the parasternal great artery short axis view,suprasternal view and DSA respectively.The demonstrated rate of the parasternal great artery short axis view was lower than that of the suprasternal view (x2 =5.14,P ＜0.025 ).The diameter of the aotic side of PDA was (8.31 ± 2.76)mm,(10.87 ± 3.26) mm and (11.15±3.29)mm and the diameter of the pulmonary side of PDA was (5.69± 2.82)mm,(5.75 ± 2.63)mm and (6.09 ± 2.78) mm respectively on the above two views and DSA.Conclusions The diameter of the aotic side of PDA can be accurately detected by using superasternal view,which would be helpful for the diagnosis of PDA subtype.
