Spontaneous anterior coronary interventricular artery dissection in a young woman in the late postpartum period: clinical case

Abstract

BACKGROUND: Cardiovascular complications during pregnancy and postpartum period are rare but often fatal. The causes and mechanisms of the development of such complications are not fully understood. Spontaneous dissection of the coronary artery against the background of the influence of sex hormones is one of the mechanisms for the development of acute coronary syndrome in the postpartum period. The false lumen of the intramural hematoma overlaps the true lumen, causing arterial obstruction, leading to acute myocardial hypoxia. Thus, awareness that the pathophysiology of spontaneous coronary artery dissection differs from that of acute coronary syndrome associated with atherosclerotic plaque rupture is important, and these patients require different treatment approaches. Currently, an unambiguous and precise strategy for this pathology has not been established, which is why difficulties remain in the management of these patients and choosing treatment strategies. CLINICAL CASE DESCRIPTION: The article describes a complex clinical case of the development of acute myocardial infarction in the postpartum period in a young woman without risk factors against the background of spontaneous dissection of the coronary artery, complicated by cardiogenic shock, which required emergency percutaneous coronary intervention and stenting of the infarct-dependent artery. The postoperative period proceeded with complications, and extracorporeal membrane oxygenation was required. However, an integrated approach and correctly chosen treatment strategies help stabilize the patients condition. CONCLUSION: Currently, no unambiguous and precise strategy of treatment has been established, so difficulties remain in the management of patients and decision making. In our opinion, an individual patient approach should be followed, taking into account the general state of the organism, type and volume of dissection, consequences and complications, and experience and technical capabilities of the clinic.
