Rupture of an isolated septal artery during diagnostic angiography in a patient with myocardial noncompaction

Myocardial noncompaction is characterized by prominent trabeculations, deep intertrabecular recesses, and a thick noncompacted endocardial myocardium. Its prevalence in the general population is still unclear, but echocardiography series report a prevalence rate of 0.05% (1). The coexistence of coronary anomaly and myocardial compaction is extremely rare (2). To the best of our knowledge, intramyocardial rupture of an isolated septal coronary artery was first defined in a patient with myocardial noncompaction and concurrent coronary anomalies
