[Abstract] The left atrial appendage (LA-Ap) is one of the major sources of cardiac thrombus formation responsible for thromboembolism inpatients with atrial fibrillation (AF). We hypothesized that the particular anatomical characteristics of the LA-Ap may facilitate thrombus formation. Methods : Seventy-four AF patients underwent transesophageal echocardiography (TEE) and multi-detector CT (MDCT) examinations. These patients were divided into two groups, with and without systemic embolism (Emb) [Emb (+) group, 10 patients, male/female =7/3 ; Emb (—) group, 64 patients, male/female = 51/13]. To evaluate the location of the LA-Ap in relation to the left atrium (LA), we determined four distinctive points on MDCT images using two carefully defined orthogonal sections : the superior summit of the mitral annulus (point-A), the anterior and posterior sites of the LA-Ap orifice (point-B and C), and the posterior LA (point-D). Next, we evaluated the relation of the geometrical intervals (A-B, B-C, C-D) to the prior thromboembolism. Results : Using multivariate analysis, a shorter A-B interval was recognized as an independent factor positively associated witha history of thromboembolism. Conclusion : The position of the LA-Ap orifice may affect the hemodynamic state of the LA-Ap, and anterior deviation of the LA-Ap orifice (low take-off of the LA-Ap) may be a risk factor for thrombus formation in LA-Ap and systemic embolism. |
