“…Усі порушення цілісності міокарда внаслідок ГІМ можна поділити на розриви вільної стінки та внутрішні розриви [8]. У структурі розривів серця найчастіше (80-95 %) спостерігається розрив вільної стінки ЛШ [9]. Проте літературні дані, присвячені дослідженню частоти поширеності різних локалізацій розривів, значно відріз-няються [3,4,10].…”

The article is dedicated to topical issues of diagnosis and surgical treatment of postinfarction left ventricular (LV) myocardial rupture. Postinfarction LV rupture is one of the most life-threatening complications of acute myocardial infarction (AMI). Given the low prevalence, this complication almost always leads to a fatal outcome. At the same time, a large proportion of patients (over 60%) die before the diagnosis is verified, suddenly, without specific clinical precursors. The aim. To draw the attention of doctors to the problem of diagnosis and surgical treatment of LV myocardial rupture as a complication of AMI. The article describes a clinical case of diagnosis of pseudoaneurysm of the LV free wall after coronary stenting. The peculiarity of this case was absence of a typical pain syndrome, electrocardiographic and echocardiographic signs, suggesting the presenceof such a mechanical complication of AMI. Special attention is paid to the analysis of factors enabling to assess the risk of developing this complication in patients with AMI. The given clinical case demonstrates the importance of early hospitalization and myocardial revascularization by stenting in order to prevent mechanical complications of AMI. Timely diagnosis and urgent surgical treatment of LV myocardial ruptures can reduce mortality due to mechanical complications of AMI. Conclusions. Timely hospitalization and revascularization of the myocardium in AMI patients reduce the risk of LV rupture in the affected area. The use of echocardiography makesit possible to detect severe complications of AMI with sufficient sensitivity. The only effective treatment method forLV rupture is urgent surgical intervention. Postinfarction myocardial rupture repair is a difficult task considering the initial severity of the patient’s clinical condition, the significant volume and technical complexity of the surgical intervention.
