Successful occlusion of ventricular septal rupture in myocardial infarction under the guidance of echocardiography

Abstract

Introduction: The traditional treatment of myocardial infarction with ventricular septal rupture is surgical treatment. For the elderly patients with cardiac insufficiency, surgical treatment is very risky. The successful treatment of this case by interventional occlusion is a new method. No relevant literature reports have been found. Case: A 77-year-old man with a past medical history of old myocardial infarction presented to the physician with sudden onset of palpitation and shortness of breath. Echocardiography showed thinning of the interventricular septum near the apex and bulging toward the right ventricular side with "paradoxical motion", on which a rupture of about 8 mm in diameter was seen. CDFI: left ventricular blood shunted to the right ventricle through the rupture.Echocardiographic diagnosis: old left ventricular anteroseptal myocardial infarction with ventricular septal rupture. Due to the older age of the patient and reduced left ventricular function, surgical repair of the ventricular septal rupture site was more difficult. After multidisciplinary discussion, it was agreed that the patient could not afford thoracotomy and was not suitable for thoracotomy, and echocardiography guided interventional occlusion of the ruptured interventricular septum could be performed. Conclusion: Transesophageal echocardiography-guided interventional occlusion of myocardial infarction with ventricular septal rupture in elderly patients with cardiac insufficiency is a new attempt, the successful treatment of this case shows that this method is feasible, for some patients is an appropriate treatment.
