The Short and Intermediate Term Efficacy of Transcatheter Closure by Homemade Amplatzer Mushroom Occluder of Patent Ductus Arteriosus for the Middle-aged or Geratic Patients

Objective: To evaluate the short and intermediate term efficacy as well as safety of transcatheter closure by homemade Amplatzer mushroom occluder of patent ductus arteriosus in the treatment of middle-aged or geratic patients. Methods: 32 cases with PDA who were confirmed by clinical manifestation, electrocardiogram(ECG), X-ray fluoroscopy, transthoracic color Doppler echocardiography(TTE) from January 2007 to December 2011 were selected and received the transcatheter occlusion. Then the follow-ups were conducted. Results: 32 cases were all successfully occluded with the rate of 100%. In follow-ups, X-ray fluoroscopy showed pulmonary venous pleonaemia reduced and cardio-thoracic ration decreased. After 48 hours, the LAD, LVDd and PASP reduced obviously(P0.01); after 1 year(30 cases), 2 years(20 cases), 3 years(12 cases) and 4 years(5 cases). There was no death, complication or therapy. Conclusion: Transcatheter closure of PDA in middle-aged or geratic patients using the homemade Amplatzer mushroom occluder was safety and efficacy with easy procedure, less complication, high successful rate and shorter hospitalization.
