Valvular atrial fibrillation carries a higher risk of thromboembolism and a greater propensity for non-cerebral emboli compared to non-valvular atrial fibrillation.
The most feared consequence of atrial fibrillation (AF) is thromboembolism, either to the brain causing stroke or to the non-cerebral circulation. Valvular atrial fibrillation (VAF) and non-valvular atrial fibrillation (NVAF) differ not only by morphological substrate of arrhythmia but also by the rate of thromboembolic complications, predisposing factors and destination of embolism. In the setting of VAF, there is a higher risk of thromboembolism and a higher prevalence of thrombus location within the body of the left atrium compared to NVAF. VAF is also associated with a proportionally higher propensity for non-cerebral thromboemboli than in NVAF. The distribution of non-cerebral thromboemboli appears to be similar in VAF and NVAF; however, more research needs to be done in this area, particularly with regard to VAF.

Blustin et al. (2014) conducted a review in Atrial fibrillation. Valvular atrial fibrillation vs. Non-valvular atrial fibrillation was evaluated on Thromboembolism. Valvular atrial fibrillation is associated with a higher risk of thromboembolism and a proportionally higher propensity for non-cerebral thromboemboli compared to non-valvular atrial fibrillation.
