Patients were collected from three institutes in the Netherlands. The characteristics of the fistulas(origin, pathway and termination), multiplicity of the origins and pathways of the fistulous vessels were assessed by CAG. Five patients underwent adenosine pharmacologic stress ^(13)N-ammonia PET-CT to assess myocardial perfusion and the functional behavior of the fistula. RESULTS Eleven patients with 12 CAFs, 10 unilateral and one bilateral, originating from the left anterior descending coronary artery(n = 8), right coronary artery(n = 2) and circumflex(n = 2). All fistulas were of the vascular type, terminating into either the pulmonary artery(n = 11) or coronary sinus(n = 1). The CAG delineated the characteristics of the fistula(origin, pathway and termination). Multiplicity of the origins and pathways of the fistulous vessels were common in most fistulas(8/12, 67% and 9/12, 75%, respectively). Multiplicity was common among the different fistula components(23/36, 64%). Adenosine pharmacologic stress ^(13)N-ammonia PET-CT revealed normal myocardial perfusion and ejection fraction in all but one patient, who showed a reduced ejection fraction.CONCLUSION PET-CT may be helpful for assessing the functional status of congenital CAFs in selected patients regarding clinical decision-making. Studies with a larger patient series are warranted.展开更多

Literature review limited to the English language. A total of 211 reviewed patients were collected. Of those, 111 were of Asian and 100 were of Caucasian ethnic origin. The mean age of the Asian and the Caucasian groups of patients were 48.9(range 19-83) and 49.9 years(range 16-85), respectively. In both groups, right heart catheterization was the most commonly(95%) used method for determining pulmonary artery pressure. RESULTS From all of the reviewed subjects, PHT was found in 49 patients(23%), of which 15 were Asian and 34 were Caucasian. In 75% of PHT subjects, mild to moderate PHT was reported and 76% of the fistulas had a vascular mode of termination. Treatment was surgical in 61%, followed by percutaneous therapeutic embolization(27%) and finally conservative medical management in 12% of PHT subjects. PHT was associated with a slight female gender predominance. The majority demonstrated mild to moderate PHT. PHT was reported more frequent in the Caucasian compared with the Asian ethnicity group. The majority of fistulas in patients with PHT had a vascular mode of termination. The results of this review are intended to be indicative and require cautious interpretation.CONCLUSION The likelihood for a CAF patient to develop PHT is presented when possessing the following features, with a Caucasian female having a fistula with a vascular mode of termination.展开更多
