Ultrasound and angiography images. a Images from transesophageal echocardiography directly prior to cardiac intervention depicting no pathological structure. b Images from transesophageal echocardiography 5 days after stroke showing a thrombus (approx. 1.4 x 0.6 cm) in the left atrial appendage. c, d Angiography images before (c) and after (d) mechanical thrombectomy of proximal M1 occlusion with one stent-retriever assisted vacuum-locked extraction (SAVE) resulted in successful reperfusion (TICI grade 2b).

Preprocedural transesophageal echocardiography on the day of ablation excluded an intracardiac thrombus (Fig. 1a). Suite. Successful mechanical thrombectomy was performed with one stent-retriever assisted vacuum-locked extraction (SAVE) with nearly complete reperfusion (Thrombolysis in Cerebral Infarction scale grade 2b) without any complications (Fig. 1d). Although transesophageal echocardiography prior to catheter ablation revealed no pathological structure, a thrombus (approx. 1.4 x 0.6 cm) in the left atrial appendage was detected 5 days after the cardiac intervention (Fig. 1b).
