Assessment of Thromboembolic Risk in Low Risk Patients with Non-Valvular AF According to CHA2DS2-VASc Score by TEE
Muhammad Hassan Ibrahim Muhammad Saleh;
Abstract
A
trial fibrillation is the most common type of cardiac arrhythmia characterized by irregular, rapid and disorganized atrial depolarizations with a discrete lack of P waves on electrocardiograms leading to an irregular ventricular rhythm (Michaud et al., 2015).
In atrial fibrillation, the atrium does not contract as strongly as it should. This can cause blood to stagnate in the heart and form clots. When the blood clots dislodge, they may move to the brain, blocking narrow brain artery flow and causing a stroke. Research suggests that over 90 percent of blood clots responsible for stroke in patients with AF originate from the left atrial appendage (LAA) (Randall et al., 2010).
Anticoaglation can be used to reduce the risk of stroke from AF. Anticoagulation is recommended for most AF patients other than those at low risk of stroke according to CHA2DS2-VASc score (Lip et al., 2015).
The aim of the study is to assess risk of thromboembolism in low risk patients with Non-Valvular AF according to CHA2DS2-VASc score using TEE and TTE and Find further reliable parameters other than detection of thrombi to exclude thromboembolic risk in this group patients.
