Effects of transcatheter closure in children with congenital coronary artery fistula / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effects of transcatheter closure method for treating congenital coronary artery fistula (CAF) in children.</p><p><b>METHODS</b>Twenty-three children with CAF received transcatheter closure. Under anesthesia, heart catheterization and selective coronary angiography were performed to show the CAF size and relationship with normal coronary artery. CAF with the narrowest inner diameter < 3 mm (n = 16) were occluded with coil device, and CAF with narrowest inner diameter > 3 mm (n = 7) were closed with Amplatzer duct or VSD occluder.</p><p><b>RESULTS</b>Transcatheter closure was successfully performed in 21 cases and failed in 2 cases (CAF is too tortuous in one case and right CAF outlet near the right coronary artery main stem in another case) and CAF were closed by surgery in these 2 patients. No residual shunt or other complications were observed during the 3 months to 3 years follow up.</p><p><b>CONCLUSION</b>Transcatheter closure was an effective and mini-traumatic method for CAF treatment in children.</p>
