RESUMO

Myocardial bridge is characterized by systolic compression of a portion of the coronary artery by a segment of overlying myocardium, commonly involves the middle segment of left anterior descending coronary artery. We present a case report of coronary angiographic evidence of systolic short segmental constriction in the proximal right coronary artery (RCA). A 42 year-old man presented with atypical chest discomfort and palpitation. Electrocardiography showed complete AV block with complete AH block on intracardiac electrocardiogram. Myocardial SPECT imaging demonstrated a mild reversible anterior and inferior wall perfusion defect. Diagnostic coronary angiogram revealed short segmental myocardial sling with wedge-shaped systolic compression in the proximal RCA.
