They most commonly result from complete occlusion of a major coronary artery. We present a unique case of concomitant left ventricular aneurysm (LVA) formation and ventricular septal rupture (VSR) requiring open surgical repair after occlusion of a small (caliber < 1 mm) diagonal branch artery during successful elective stenting of the left anterior descending coronary artery (LAD). Multimodality imaging was integral to the correct diagnosis and therefore treatment of this rare pathology.
