Right Ventricular Infarction Associated with Anteroseptal Myocardial Infarction: A Clinicopathologic Study of Nine Cases

摘要: The association of right ventricular (RV) infarction with inferoseptal myocardial is well established. However, a question remains about the occurrence RV in anteroseptal infarction. To determine frequency and clinical correlates this entity, we studied autopsied hearts from patients isolated left (LV) infarcts. Among 3,249 autopsy specimens, 88 cases were identified. From each, sections taken anterior, lateral, inferior regions at basal, middle, apical levels. All 1,584 slides reviewed by blinded assessment. LV infarcts compared to confirm similarity age. Patient records cardiac investigations for evidence involvement. Of infarcts, 9 (10%) had coexistent (6, old; 3, new). For these 9, involved 11% 33% area, anterior descending coronary artery was infarct-related each. 3 who an echocardiographic examination within 4 weeks dysfunction. One patient, 15 years after infarction, normal ventricle echocardiography. In acute heart catheterization during phase revealed increased right-sided diastolic pressures out proportion left-sided (right atrial pressure pulmonary capillary wedge pressure, 60% 95%). conclusion, 10% infarct free wall associated identifiable hemodynamic features.
