Background A coronary cameral fistula is a rare connection between a coronary artery and a cardiac chamber or vein bypassing the cardiac capillary bed system. Most of these fistulae are congenital and solitary, although they can be acquired and multiple. Cases presentation Case 1: A 10-year-old black South African boy presented with a long-standing history of fatigue; he had a heart murmur, and a bounding pulse and wide pulse pressure. An echocardiogram demonstrated a large coronary cameral fistula involving his left coronary artery and his left ventricle. This was also confirmed on ascending aortogram. Surgical ligation was done and his symptoms improved afterward, but a small residual fistula remained. Case 2: A 7-year-old black South African boy had decreased effort tolerance and a heart murmur on the mid-sternal border. He had cardiomegaly on chest roentgenogram and a dilated left coronary artery origin on echocardiogram. An ascending aortogram confirmed a large left coronary cameral fistula draining to the left ventricle. Case 3: A 28-year-old black South African woman with decreased effort tolerance and chest pain on exertion had a continuous murmur over the lower sternal border. Echocardiography demonstrated a dilated right coronary artery with a fistulous connection to her right ventricle. An ascending aortogram demonstrated a tortuous coronary cameral fistula arising from her right coronary artery to her right ventricle. All three patients were successfully treated percutaneously using the Amplatzer vascular plug type II device. Conclusion The availability of numerous vascular closure devices has made transcatheter occlusion the treatment of choice for the majority of coronary cameral fistulae, rather than the traditional surgical ligation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
