TCTAP C-025 Embolic Myocardial Infarction Caused by Left Atrium Emboli from Atrial Fibrillation

Left atrium segmentation for atrial fibrillation ablation

Segmentation of the left atrium is vital for pre-operative assessment of its anatomy in radio-frequency catheter ablation (RFCA) surgery. RFCA is commonly used for treating atrial fibrillation. In this paper we present an semi-automatic approach for segmenting the left atrium and the pulmonary veins from MR angiography (MRA) data sets. We also present an automatic approach for further subdividi...

ST-elevation myocardial infarction caused by thromboembolism from the left atrial appendage.

A 64-year-old gentleman was admitted for primary percutaneous coronary intervention (PCI) after he experienced chest pain while drinking alcohol in a pub. The electrocardiograms demonstrated atrial fibrillation (AF) with a rapid ventricular response rate and transient ST-segment elevation with loss of R waves in the anterior leads (Figure 1). Coronary angiography revealed a thrombotic occlusion...

Does myocardial infarction beget atrial fibrillation and atrial fibrillation beget myocardial infarction?

Embolic Myocardial Infarction as a Consequence of Atrial Fibrillation: A Prevailing Disease of the Future.

A cute myocardial infarction (AMI) is a major cause of death and disability worldwide. When spontaneous AMI occurs, there is a >90% chance that the underlying etiology is primarily due to coronary events such as plaque rupture, erosion , or dissection referred to as myocardial infarction (MI) type 1. 1 MI can also occur secondary to an ischemic insult in the absence of overt coronary artery dis...

Acute embolic myocardial infarction in a patient with paroxysmal atrial fibrillation receiving direct-current cardioversion.

Coronary embolism with acute myocardial infarction (MI) following direct-current (DC) cardioversion of atrial fibrillation (AF) has rarely been reported. We present the case of a 34-year-old female with severe aortic regurgitation and highly symptomatic paroxysmal AF. Acute embolic MI occurred 4 days after DC cardioversion of AF, although there was no left atrial thrombus detected before this p...
