UNEXPECTED COMPLICATION – A CASE OF STEMI OF THE POSTERO-LATERAL WALLOF THE LEFT VENTRICLE COMPLICATED BY A LEFT ATRIAL INFARCTION

Abstract

We present a clinical case of a patient with a left atrial infarction, that occurred during a left ventricular infarction. Although a rare nosological entity, left atrial infarction is a potentially dangerous complication, which is most often expressed in the development of different types of rhythm and conduction disorders. The patient comes with symptoms of acute heart failure against the background of acute left ventricular infarction, treated with percutaneous coronary intervention (PCI), followed by an acute left atrial infarction due to occlusion of the atrial branch of the circumflex artery. In the days after the procedure with severe electrical instability, multiple episodes of tachycardia, alternating with bradycardia. The complication in question was proven and followed up, both angiographically and echocardiographically. Various strategies were applied to control the patient’s condition, which resulted in stabilization of the electrical activity and the most favourable outcome in the given case.
