Myocardial infarction in a 67-year-old man was complicated by an interventricular defect (Fig. 1) . The communication did not occur via a bretch in the septum, but rather via a tunnel through the inferior myocardial wall from the left to the right ventricle. This case combines patterns of ischemic myocardial rupture and interventricular septal defect.

Images from left ventriculogram (A) and two-dimensional echocardiography (B) of the non-septal, tunneled interventricular communication running through the left ventricular wall and draining into the right ventricle. The arrows indicate the defect. LV, left ventricle; RV, right ventricle.
