Reversible right bundle branch block caused by spasm of the anterior septal branch: case report.

ABSTRACT:

Background

Coronary Artery Spasm (CAS) often presents in the epicardial coronary arteries. The anterior septal branch is distributed within the myocardium, and occurrences of spasms are rare. Currently, there is no available literature on this topic, and the onset of symptoms remains elusive, potentially leading to misdiagnosis.

Case presentation

We present a case of acute myocardial infarction (AMI) caused by spasm in the anterior septal branch, accompanied by transient right bundle branch block (RBBB). The administration of nitroglycerin via intracoronary injection resulted in the alleviation of spasm in the anterior septal branch and the disappearance of RBBB. After the administration of anti-coronary spasm medications, the patient exhibited favorable recovery outcomes. N
