Abstract:
Objective To evaluate the value of transthoracic echocardionraphy(TTE)and angiographic appearance for measurement of the diameter of patent ductus arteriosus(PDA)in transcatheter interventions.Methods In 52 patients,the position,diameter and length of ductus arteriosus between the descending aorta and the pulmonary artery were observed and the narrowest diameter of PDA was measured by TTE.In angiographic appearance,pig catheter was selected to perform left lateral aortography and measure the narrowest diameter of PDA.Comparative studies were performed on the numbers measured by 2 methods.Results Aortography showed that 45 patients had funnel shape PDA and 5 patients had tubular shape PDA,while 1 patient had funnel plus tubular shape PDA and 1 patient had residual shunt after operation.TTE showed that 46 patients had funnel shape PDA,4 patients had tubular shape PDA and 1 patient had window shape PDA,1 patient had residual shunt after operation.The mean diameter of PDA measured by angiographic appearance was(3.72?2.51)mm,which was statistically lower than those by TTE(4.47?2.31)mm(t=5.17 P
