Abstract

Myocardial bridge (MB) is a congenital abnormaly that the a part of an epicardial artery follows a route inside myocardium and leads to narrowing with systolic compression. Most commonly seen in left anterior descending artery (LAD). By means of compression and endothelial dysfunction it can lead coronary ischemia and various clinical presentations. Our case presented to our clinic with inferior myocardial infarction and primary percutenous intervention performed for right coronary artery (RCA). No reflow developed during intervention and glycoprotein IIb-IIIa infusion given to patient. Control coronary angiography revealed a dissecting lesion with a 80% stenosis at the distal of RCA after the infarct related lesion and a myocardial bridge with a 99% stenosis at the posterior descending artery (PDA). Myocardial bridging at the PDA is a very rare situation. Percutenous intervention on those lesions during acute coronary syndrome may result with no-reflow phenomena. Myocardial bridging may increase the risk of no-reflow in acute coronary syndromes.

Abstract

Bu yayında akut koroner sendromlarda sorumlu lezyon distalinde kalan miyokardiyal köprülemeyle işlem esnasında gelişebilecek no-reflow fenomeni arasındaki ilişki değerlendirilmiştir. Miyokardiyal köprüleme, epikardiyumda seyreden koroner arterlerin bir bölümünün kas içinde seyretmesi ile ortaya çıkan ve sistolik bası sonucu arterlerde daralmaya yol açan konjenital anomalidir. Neden olduğu sistolik bası ve endotel disfonksiyonu nedeniyle koroner iskemiye yol açarak çeşitli klinik tablolara yol açabilir. Vakamızda alt yüz kalp krizi nedeniyle Sağ Koroner Arter'e (RCA) acil perkütan girişim yapıldı. İşlem sırasında no-reflow gelişmesi nedeniyle hastaya glikoprotein IIb-IIIa infüzyonu verildi. Ardından yapılan kontrol koroner anjiyografide RCA orta bölgede enfarktüsden sorumlu %80 darlık yapan disseke lezyon, takip eden RCA'nın arka inen dalında (PDA) %99 darlık yapan miyokardiyal köprüleme tespit edildi. PDA tutulumlu miyokardiyal köprüleme nadir bir durumdur. Akut koroner sendrom nedeniyle yapılacak perkütan girişimlerde miyokardiyal köprüleme no-reflow gelişme riskini arttırabilir.
