Is endovascular thrombectomy safe and effective for acute ischemic stroke caused by new-onset atrial fibrillation after TAVI?
Endovascular thrombectomy can be an effective and safe treatment for acute ischemic stroke caused by new-onset atrial fibrillation in the subacute phase after TAVI.
BACKGROUND: Thromboembolic events are infrequent but serious complications of transcatheter aortic valve implantation (TAVI), occurring in 2.3-10% of the patients. However, the cause of post-TAVI stroke is unclear. CASE DESCRIPTION: A 90-year-old female underwent transfemoral-TAVI for severe aortic stenosis. Ten days later, she presented with an ischemic stroke of the left middle cerebral artery territory due to new-onset atrial fibrillation (NOAF). She underwent emergent endovascular thrombectomy with good reperfusion approximately 6 hours after onset of symptoms. At hospital discharge, her National Institutes of Health Stroke Scale score was 11. CONCLUSIONS: Although NOAF is rare during the subacute phase of TAVI, in this patient it might be the cause of her stroke. This finding suggests that dual antiplatelet therapy alone may be insufficient in the prevention of stroke after TAVI. Nonetheless, this case demonstrates the efficacy and safety of endovascular thrombectomy in patients with acute ischemic stroke caused by NOAF after TAVI.
Matsuo et al. (Sun,) conducted a case report in Ischemic stroke after transcatheter aortic valve implantation (n=1). Endovascular thrombectomy was evaluated on Reperfusion and National Institutes of Health Stroke Scale (NIHSS) score at hospital discharge. Endovascular thrombectomy achieved good reperfusion in a 90-year-old female with acute ischemic stroke caused by new-onset atrial fibrillation 10 days after TAVI, with an NIHSS score of 11 at discharge.
