Myocardial Perfusion Imaging (MPI) as an Assessment Tool for Coronary Haemodynamics in A Patient with Myocardial Bridging of the Right Coronary Artery at Universitas Academic Hospital, South Africa; A Case Discussion

We report a case of assessment of haemodynamics of myocardial bridging (MB) of the right coronary artery using myocardial perfusion imaging (MPI). Although most patients with MB are asymptomatic, some may present with ischemia and related complications, including myocardial stunning, infarction, arrhythmia, AV block, transient LV dysfunction and sudden death and hence it becomes necessary to evaluate the hemodynamics of these patients with MB whether symptomatic or not using MPI which is effective and noninvasive. The index case was a 61 year old man found to have myocardial bridging of the right coronary artery. He had no preceding symptom of ischaemia. Myocardial perfusion imaging however established the presence of inferior wall ischaemia in the absence of any coronary artery lumen narrowing.
