Abstract:

Objective To introduce the experience of using Amplatzer Duct Occluder Ⅱ (ADO Ⅱ) for closing coronary artery fistula and to analyze its efficacy and safety. Methods Clinical data of patients whose coronary artery fistulas were closed by ADO Ⅱ between September 2011 and October 2013 were collected. The retrospective analysis was conducted according to operation and short-term follow-up outcomes. Results The average age of 5 patients was 3.8 years. Among 4 cases of right coronary-right ventricular fistulas, 3 cases used 4 mm×6 mm ADO Ⅱ and 5F delivery sheath, while the other case used 4 mm×4 mm ADO Ⅱ and 4F delivery sheath. One case of left coronary-right ventricular fistula used 4 mm×6 mm ADO Ⅱ and 5F delivery sheath. Intraoperative angiography and postoperative echocardiography showed no residual shunt and the results of electrocardiogram were normal the next day after operations. The average follow-up time was 16 months and no complications were found. Conclusion The delivery sheath of ADO Ⅱ is small and soft, which facilitates for approaching the fistula and efficiently closing the coronary artery fistula.
