Abstract

Introduction: Myocardial Bridge (MB), which is a congenital coronary artery anomaly, is characterized by remaining of a segment of an epicardial coronary artery in the myocardium. The degree of coronary obstruction caused by MB depends on its location, thickness, length and the degree of cardiac contractility. Although its prevalence in autopsy studies is reported to be as high as 80%, coronary angiography studies report a varying prevalence between 0.5% and 16%.Patients and Methods: The study was conducted retrospectively between November 2011 and October 2013 at Dumlupınar University School of Medicine Evliya Çelebi Training and Research Hospital. Angiographic records of 3835 patients who underwent coronary angiography were retrospectively analyzed in order to investigate the prevalence of MB.Results: Among 3835 patients undergoing coronary angiography, 62 had MB and the angiographic prevalence was calculated as 1.61%. The average age of the patients was 57.1, the youngest was 30 and the oldest was 82 years old. Of the patients, 12 (19%) were females and 50 (81%) were males. MB was most frequently observed in the left anterior descending (LAD) artery. 30 patients (48%) had MB in mid LAD, 30 (48%) had in distal LAD,1 (2%) had in circumflex (Cx) artery, and 1 (2%) had in right coronary artery (RCA).Conclusion: In our study, the prevalence of MB was found similar to the values presented in various angiography studies in the literature. MB was found significantly more common in males. Also, MB was detected most frequently in the LAD artery.

Özet

Giriş: Doğumsal bir koroner arter anomalisi olan Miyokardiyal Bridge (MB), epikardiyal koroner arterlerden birinin bir segmentinin miyokardiyum içerisinde seyretmesi ile karakterize bir durumdur. MB tarafından oluşturulan koroner obstrüksiyonun derecesi, MB'nin lokalizasyonuna, kalınlığına, uzunluğuna ve kardiyak kontraktilitenin derecesine bağlıdır. Otopsi çalışmalarında prevalansı %80 kadar yüksek bulunmasına rağmen, koroner anjiografi çalışmalarında prevalansı %0,5 ile %16 arasında değişmektedir.Hastalar ve Yöntem: Çalışmamız retrospektif olarak yapıldı. 2011 Kasım ve 2013 Ekim tarihleri arasında Dumlupınar Üniversitesi Tıp Fakültesi Evliya Çelebi Eğitim ve Araştırma Hastanesi'nde koroner anjiografi yapılan 3835 hastanın anjiografik kayıtları MB'nin prevalansını araştırmak için retrospektif olarak tarandı.Bulgular: Koroner anjiografi yapılan toplam 3835 hastanın 62'sinde MB bulundu ve anjiografik prevalansı %1,61 olarak hesaplandı. Hastaların yaş ortalaması 57,1 iken, en küçük yaş 30, en büyük yaş 82 olarak bulundu. Toplam hastaların 12'si (%19) kadın iken, 50'si (%81) erkek olarak bulundu. MB en sık olarak sol ön inen (LAD) arterde bulundu. Mid LAD'de 30 hastada (%48), distal LAD'de 30 hastada (%48), sirkumfleks (Cx) arterde bir hastada (%2) ve sağ koroner arterde (RCA) bir hastada (%2) olarak tespit edildi.Sonuç: Çalışmamızda MB'nin prevalansı literatürdeki anjiografi çalışmalarına benzer olarak bulundu. Erkeklerde belirgin olarak daha yaygın tespit edildi. Ayrıca MB en sık olarak LAD arterde tespit edildi.
