A rare case of myocardial bridging as a cause of complete heart block: A diagnostic challenge

Blog Article

Complete heart block (CHB) is a disruption in electrical impulses to travel from atria to ventricles and can rarely be caused by myocardial bridging (MB), where cardiac tissue compresses a coronary artery during systole.The incidence of MB ranges from 0.5 % to 16 % in coronary angiography patients.

This case report presents a 30-year-old female presented with iphone 14 price arizona dizziness, shortness of breath, and chest pain, diagnosed with third-degree AV block.Echocardiography revealed interventricular septal thickening and mild mitral regurgitation.Coronary angiography identified myocardial bridging in the mid LAD artery causing significant systolic stenosis.

After ruling out reversible causes, a dual-chamber permanent pacemaker was implanted due to persistent heart block.The patient remained stable postprocedure, with decreasing cardiac biomarkers, and was discharged symptom-free with a follow-up appointment scheduled.MB can lead to serious cardiovascular events, including myocardial infarction hbl5266ca and CHB.

Clinicians must recognize the risks associated with MB and maintain a high suspicion for CHB to ensure timely management.Further studies are needed to clarify the CHB-MB relationship and improve patient outcomes.
