A 72-year-old man was admitted to the local hospital with non-ST elevation myocardial infarction. In the first 24 hours, a new onset apical murmur was heard. Transthoracic and transesophageal echocardiography showed interventricular septal (IVS) rupture and dissection of the right ventricle (RV) wall forming an echolucent pseudocavity that partially occupied the RV and communicated with the true RV cavity. Multislice computed tomography characterized in detail the IVS and RV wall dissection, and further showed the right coronary artery in the outer border of the RV and pseudocavity, excluding pericardial fluid. Despite surgical correction, progression to cardiogenic shock and death occurred 33 days after admission.
