Abstract

Reverse redistribution pattern (RRP) is defined as the presence of a perfusion defect on the resting cardiac image, rather than on the exercise image. RRP is relatively uncommon. Recent reports suggest that RRP seems to represent segments with a mixture of viable and nonviable myocardial tissue that are frequently supplied by patent infarct-related arteries. We report a 75-year-old man who was detected to have reverse redistribution pattern associated with atrial fibrillation and coronary artery disease on $^{99m}$Tc-MIBI myocardial perfusion study. In this review, we report a case and discussed possible pathophysiological mechanism of the perfusion abnormality.

Özet

Revers redistribüsyon paterni (RRP) egzersizde bulunmazken veya hafifken istirahatte bir perfüzyon defektinin ortaya çıkması veya artması olarak tanımlanır. RRP göreceli olarak seyrektir. Yeni çalışmalar RRP'nin açık infarktüs arteriyle beslenen canlı ve nekrotik dokuların karışımı olan bölgelerde gözlendiğini düşündürmektedir. Bu derlemede $^{99m}$Tc-MIBI miyokard perfüzyon çalışmasında RRP saptanan, koroner arter hastalığı ve atriyal fibrilasyonu olan 75 yaşında bir erkek hasta bildirildi ve bu perfüzyon anormalliğinin olası fizyopatolojik mekanizmaları tartışıldı.
