Abstract

Objective: 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%. Materials and Methods: The study was conducted retrospectively between November 2006 and October 2015 at Yuzuncu Yil University Faculty of Medicine. Angiographic records of 18500 patients who underwent coronary angiography were retrospectively analyzed in order to investigate the prevalence of MB. Results: Among 18500 patients undergoing coronary angiography, 203 had MB and the angiographic prevalence was calculated as 1.11%. The average age of the patients was 59.3, the youngest was 28 and the oldest was 84 years old. Of the patients, 40 (20%) were females and 163(80%) were males. MB was most frequently observed in the left anterior descending (LAD) artery. 59 patients (29%) had MB in distal LAD, 142 (70%) had in mid LAD, and 2 (1%) had in circumflex coronary artery (Cx). 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

Amaç: Koroner arter anomalisi olan Myokardiyal köprüleşme (MB), epikardiyal koroner arterlerden birinin bir segmentinin miyokardiyum içerisinde seyretmesi ile karakterize bir durumdur. MB tarafından oluşturulan koroner obstrüksiyonun derecesi, MB'nin yerleşimine, 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. Gereç ve Yöntem: Çalışmamız retrospektif olarak yapıldı. 2006 Kasım ve 2015 Eylül tarihleri arasında yüzüncü yıl üniversitesi tıp fakültesinde koroner anjiografi yapılan 18500 hastanın anjiografik kayıtları MB'nin prevalansını araştırmak için retrospektif olarak tarandı. Bulgular: Koroner anjiografi yapılan toplam 18500 hastanın 203'ünde MB bulundu ve anjiografik prevalansı %1,11 olarak hesaplandı. Hastaların yaş ortalaması 59,3 iken, en küçük yaş 28, en büyük yaş 84 olarak bulundu. Toplam hastaların 163'ü (%80) erkek iken, 40'ı (%20) kadın olarak bulundu. MB en sık olarak sol ön inen (LAD) arterde bulundu. Distal LAD'de 59 hastada (%29), midLAD'de 142 hastada (%70), sirkumfleks (Cx) arterde 2 hastada (%1) 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.
