AI Summary & Key Takeaways
AI InsightTwelve (30%) of the fistulas were draining into the pulmonary trunk, eight (20%) into the left ventricle, seven (17.5%) into the right ventricle, five (12.5%) into the superior vena cava, three (7.5%) into the right main pulmonary artery, two (5%) into the right atrium, one (2.5%) into the left atrium, one (2.5%) into the right internal thoracic artery, and one (2.5%) into the sinus coronarius.Conclusion: Compared to conventional angiography, multislice computed tomographic angiography is a non-invasive modality which allows enhancing coronary artery fistulas at a higher rate and visualizing the cardiac anatomy in detail.

Abstract
Background: This study aims to investigate the frequency and the anatomical features of coronary artery fistulas in patients undergoing multislice computed tomographic angiography for various reasons. Methods: Between January 2009 and July 2015, a total of 40 coronary artery fistulas of 26 patients were retrospectively analyzed using multislice computed tomographic angiography in our clinic. The affected arteries and localizations of the fistulas were evaluated.Results: Of the fistulas, 11 (27.5%) were originating from the circumflex artery, 10 (25%) from the left anterior descending artery, four (10%) from the diagonal arteries, three (7.5%) from the left main coronary artery, three (7.5%) from the right main coronary artery, three (7.5%) from the septal artery, three (7.5%) from the conus artery, one (2.5%) from the obtuse marginal artery, one (2.5%) from left anterior descending artery proper (dual LAD), and one (2.5%) from the ramus intermedius. One of the conus arteries was directly originating from the right coronary sinus. Twelve (30%) of the fistulas were draining into the pulmonary trunk, eight (20%) into the left ventricle, seven (17.5%) into the right ventricle, five (12.5%) into the superior vena cava, three (7.5%) into the right main pulmonary artery, two (5%) into the right atrium, one (2.5%) into the left atrium, one (2.5%) into the right internal thoracic artery, and one (2.5%) into the sinus coronarius.Conclusion: Compared to conventional angiography, multislice computed tomographic angiography is a non-invasive modality which allows enhancing coronary artery fistulas at a higher rate and visualizing the cardiac anatomy in detail.
Özet
Amaç: Bu çalışmada çeşitli nedenlerle çok kesitli bilgisayarlı tomografik anjiyografi incelemesi yapılan hastalarda koroner arter fistüllerinin sıklığı ile anatomik özellikleri araştırıldı. Çalışma planı: Ocak 2009 - Temmuz 2015 tarihleri arasında kliniğimizde çok kesitli bilgisayarlı tomografik anjiyografi kullanılarak 26 hastada toplam 40 adet koroner arter fistülü retrospektif olarak incelendi. Etkilenen arterler ve fistüllerin yerleşim yerleri değerlendirildi. Bulgular: Fistüllerin 11’i (%27.5) sirkümfleks arterden, 10’u (%25) sol ön inen arterden, dördü (%10) diagonal arterden, üçü (%7.5) sol ana koroner arterden, üçü (%7.5) sağ ana koroner arterden, üçü (%7.5) septal arterden, üçü (%7.5) konus arterinden, biri (%2.5) obtus marjinal arterden, biri (%2.5) sol ön inen arter properden (dual LAD) ve biri (%2.5) ramus intermediustan köken almaktaydı. Konus arterlerinden biri doğrudan sağ koroner sinüsten köken almaktaydı. Fistüllerden 12’si (%30) pulmoner trunkusa, sekizi (%20) sol ventriküle, yedisi (%17.5) sağ ventriküle, beşi (%12.5) superior vena kavaya, üçü (%7.5) sağ ana pulmoner artere, ikisi (%5) sağ atriyuma, biri (%2.5) sol atriyuma, biri (%2.5) sağ internal torasik artere ve biri de (%2.5) sinüs koronariusa açılmaktaydı. Sonuç: Konvansiyonel anjiyografiye kıyasla, çok kesitli bilgisayarlı tomografi anjiyografi koroner arter fistüllerinin daha yüksek oranda tespit edilebilmesine ve kalp anatomisinin ayrıntılı bir şekilde görüntülenebilmesine olanak sağlayan invaziv olmayan bir yöntemdir.
