“…This shows that AF contributes to the enlargement of the atria, although it cannot be ruled out that this enlargement of the atria sometimes precipitates the development of AF. Similar results were obtained by Keren et al 38 and Presti et al, 39 and the results are indirectly supported by the success of electrical cardioversion therapy, which is related to the duration of AF and the degree of left atrial enlargement. 40 The finding that the left atrial dimension increases with the duration of AF may contribute to the decision to use electrical cardioversion therapy, especially when the duration of AF is unknown.…”

I review the present understanding of thromboembolic complications and their prevention in patients with nonrheumatic atrial fibrillation. Chronic atrial fibrillation carries an annual 3-6% risk of thromboembolic complications, which is 5-7 times greater than that of controls with sinus rhythm. Paroxysmal atrial fibrillation is associated with a lower risk of thromboembolic complications than chronic atrial fibrillation. Heart failure and systemic hypertension seem to be significant clinical risk factors for stroke in patients with atrial fibrillation, but disagreement persists, and, with few exceptions, subgroups at particular risk have not been convincingly identified. The risk of stroke in persons with thyrotoxic atrial fibrillation seems to be lower than believed previously. Clinical studies have shown that left atrial dilatation is a consequence of the duration of atrial fibrillation rather than a cause, but the relation of left atrial enlargement to stroke is uncertain. Cerebral blood flow may be reduced during atrial fibrillation but seems to increase after cardioversion to sinus rhythm. A high prevalence of silent cerebral infarction has been detected in patients with chronic atrial fibrillation, but there seems to be a low risk of silent cerebral infarction in persons with paroxysmal atrial fibrillation. The one prospective study published to date on stroke prevention in patients with nonrheumatic chronic atrial fibrillation showed that anticoagulation with warfarin significantly reduced the incidence of thromboembolic complications.

“…Small patient cohorts suggest that echocardiographic measurements of LA diameter correlate with the probability of maintaining sinus rhythm after spontaneous, chemical, or direct current cardioversion of AF. This association has been supported by some (4,(15)(16)(17)(18)(19)(20)(21) but not all (22)(23)(24)(25) studies. The LA volume measured by transthoracic echocardiography may be superior to LA diameter for predicting adverse outcomes, including recurrent AF.…”

“…The video-taped images were analyzed using a Panasonic AG-6200Q videotape pro viding slow speed and frame by frame forward features. Left and right atrial measurements were obtained from two-dimensional echograms with the largest left (LAA) and right (RAA) atrial areas at the end of ventricular systole [13][14][15]. The left and right atrial out lines at end systole for measurements of LAA and RAA were traced using a microcomputer with a digitizer (NEC PC-8001 mk II).…”

Fetal and early neonatal atrial measurements correlating with plasma atrial natriuretic peptide were studied to evaluate the circulatory change before and after delivery in a longitudinal study of 10 normal fetuses from 1 week before until 5 days after delivery. Before delivery, right atrial area value was significantly larger than that of left atrial area; however, there were no significant differences between left and right atrial areas after delivery. Right atrial area value before delivery was significantly larger than those after delivery, whereas the left atrial area did not change before and after delivery. Combined atrial area value before delivery was also larger than those after delivery. Plasma atrial natriuretic peptide values did not change after delivery. These results suggest that the change from fetal to neonatal circulation mainly caused by the pulmonary circulation induces the change of right atrial size before and after delivery.
