Transcatheter aortic valve implantation (TAVI) is a minimally invasive alternative to open-heart surgery for high-risk patients with severe symptomatic aortic stenosis. However, with reported incidence of 5–10%, acute ischemic stroke remains a serious complication significantly increasing morbidity and mortality among patients undergoing a TAVI procedure [1]. Therefore, several cerebral embolic protection devices aiming to prevent procedural debris reaching the cerebral circulation were introduced. Nevertheless, if ischemic stroke should occur, immediate mechanical thrombectomy is reported to be the most effective therapeutic option [2]. A 77-year-old man with symptomatic high-grade aortic stenosis (EuroSCORE 4.61%) was admitted to the Cardiosurgery Department for operative treatment. Due to a history of triple coronary artery bypass graft surgery and percutaneous coronary interventions he was qualified for a TAVI procedure. Under all sterile conditions and in local anesthesia with analgosedation both right (surgical) and left (percutaneous) femoral access was obtained and pre-implantation balloon aortic valvuloplasty performed. After valvuloplasty, the symptoms of a left-hemispheric stroke (decreased level of consciousness, aphasia, partial gaze palsy, hemianopia and hemiparesis) were observed. The patient’s National Institutes of Health Stroke Scale (NIHSS) score was 12. Immediate cerebrovascular angiography was performed by an on-call neuroradiologist. It revealed occlusion of the left middle cerebral artery (MCA) at the proximal M1 segment (Figure 1 B). Mechanical thrombectomy was performed with an aspiration device (Penumbra, CA, US). Complete recanalization of the vessel marked as Thrombolysis in Cerebral Infarction (TICI) 3 was confirmed in follow-up angiography (Figure 1 C). Afterwards, ACURATE neo L valve (Boston Scientific, MA, US) was deployed with no complications. Control angiography and transesophageal echocardiogram (TEE) confirmed the correct position of the valve (Figure 1 D).
After the procedure the patient’s condition improved. Control noncontrast computed tomography performed 24 hours after thrombectomy ruled out hemorrhagic transformation of infarction. After 10 days of hospitalization he was discharged with no signs of paralysis but persistent aphasia, minor facial paralysis, partial hemianopia, mild sensory loss and inattention on one side (NIHSS 8). TEE at discharge showed significant improvement: mean...
