英文摘要 | Transcatheter occlusion of secundum atrial septal defect has been tried since 1976. Some investigators have incorporated on-line transesophageal echocardiography so as to better monitor the procedure. Most, however, have used endotracheal intubation and general anesthesia. The aim of this study was to evaluate the feasibility of adjunct guidance using on-line transesophageal echocardiography without intubation and general anesthesia in adolescent or adult patients undergoing transcatheter occlusion of secundum atrial septal defects. Ten consecutive cases (age 15 - 68 years) of secundum atrial septal defects with a pulmonary to systemic flow ratio of > 1.5 and a balloon-stretched diameter of < 25 mm were enrolled in the study. The Sideris' buttoned devices were used. The procedure was guided by on-line transesophageal echocardiography and fluoroscopy. Endotracheal intubation and general anesthesia were not employed. The diameters of the atrial septal defects ranged from 6 to 19 mm as determined by transesophageal echocardiography, from 7 to 20 mm as determined by atrial angiography and from 11 to 25 mm as determined by balloon sizing. The Sideris' buttoned devices were successfully deployed in all the patients. On-line transesophageal echocardiography greatly facilitated balloon sizing, device deployment and immediate assessment. One device unbuttoned 24 hours after the procedure and was retrieved smoothly. The remaining 9 patients were followed-up for 12 months. Two patients had no shunt, 3 had a trivial (average diameter by transesophageal echocardiography = 1 - 3 mm) and 4 had a small (average diameter = 4 - 6 mm) residual shunt at the latest follow-up. The cardiothoracic ratios decreased from 0.52 + 0.06 to 0.48 + 0.06 (p = 0.0131). There was no mortality, stroke or device fracture during the follow-up period. Thus, transcatheter occlusion of secundum atrial septal defect under adjunct guidance using on-line transesophageal echocardiography without endotracheal intubation and general anesthesia is promising for selected patients. |
