Isolated Septal Branch Occlusion Causing Septal Myocardial Infarction, With Suspected Embolic Etiology From Left Atrial Appendage Thrombus: A Case Report
A. Jano, A. Hamadanchi, A. Große, P. C. Schulze, R. Surber
TL;DR
A 76-year-old woman with atrial fibrillation had a heart attack caused by a blood clot from her left atrial appendage, highlighting the need for proper anticoagulation.
Contribution
This case report presents a rare instance of septal myocardial infarction caused by embolic occlusion from a left atrial appendage thrombus.
Findings
The patient's septal myocardial infarction was linked to a thrombus in the left atrial appendage.
Discontinued anticoagulation therapy likely contributed to clot formation and subsequent embolism.
Abstract
We present a case of a 76‐year‐old female who experienced an isolated embolic occlusion of the septal branch, resulting in a septal myocardial infarction (MI) due to a thrombus in the left atrial appendage (LAA). The patient′s history included atrial fibrillation (AF), multiple allergies, and a self‐discontinued anticoagulation regimen. This case underscores the importance of anticoagulation therapy in AF patients and highlights the challenges of managing patients with complex medical histories and medication intolerances.
