1112 DOUBLE RUPTURE OF INTERVENTRICULAR SEPTUM AFTER MYOCARDIAL INFARCTION

Abstract

Abstract Ventricular septal rupture (VSR) is a mechanical complication of acute myocardial infarction (MI). VSR and early surgical repair is associated with a high mortality rate and suboptimal results with frequent postoperative residual shunt. Rapid diagnosis and proper management are critical. We present the case of a 73-year-old patient who came to our Emercency Room (ER) reporting oppressive chest pain and profuse sweating . The physical examination showed a 4/6 L rude holosystolic murmur in right parasternal location. Electrocardiogram (ECG) showed inferior MI. Hematochemicals tests detected an increase of myocardial necrosis markers. Two-dimensional and three-dimensional transthoracic echocardiography (TTE) showed normal-sized left ventricle with akinesia of inferior and posterolateral walls and akinesia of posterior basal septum with ventricular septal rupture at this level. Coronary angiography showed total occlusion in mid right coronary artery (RCA). An intra-aortic balloon pump (IABP) was inserted to promote hemodynamic stability of the patient and as a bridge. Afterload was reduced using vasodilatators. A preoperative transesophageal echocardiography (TOE) showed the presence of an additional septal rupture into middle posterior interventricular septum. The role of echocardiographic assessment in VSR, therapeutic management, IABP use and timing of surgery are discussed.
