Background: Myocardial infarction (MI) was previously thought to be a disease affecting mainly the left ventricle. Right ventricular infarction was just a pathological entity. Several authors had recognized the presence of the right ventricular (RV) dysfunction of acute MI but little attention was paid to its clinical significance. The relevance of RV function, is poorly defined in post-AMI patients. The involvement of the RV during inferior AMI has been defined as a strong predictor of major complications and in-hospital mortality that often more than 25% compared to patients without RV involvement. Percutaneous coronary intervention (PCI), known as coronary angioplasty, is a nonsurgical technique for treating obstructive coronary artery disease This article aimed to review the percutaneous Coronary Intervention of right coronary artery on right ventricular function after acute inferior myocardial infarction.
