Myocardial Infarction Seen Tardively Complicated by Ventricular Septal Rupture Extending to the Right Ventricule: A Dilemmatic Scenario

Ventricular septal rupture (VSR) is an uncommon but well-recognized mechanical complication of acute myocardial infarction (MI). Mortality without intervention is 70% in intrahospital at 30 days, and 90% at one year due to cardiogenic shock. Transthoracic echocardiography (TTE) is the choice tool in the diagnosis and evaluation of VSR. We report an original case of a 72-year-old patient diagnosed with myocardial infarction of the inferior wall of the left ventricle, complicated by the rupture of its basal segment aneurysm extending to the right ventricle. After which standard drug treatment was prescribed. Inferior wall myocardial infarction complicated with VSR at its basal segment is a rare mechanical complication of MI and this clinical case shows a rare location of VSR compared to forms described in the literatures. On the third day, the patient died from refractory cardiogenic shock, and neurological complications which could have been prevented by surgery. Treatment of VSR secondary to MI is an emergency based on either an open heart surgery or percutaneous intervention inorder to reduce morbi-mortality rate.
