Figure Legends:
Figure 1. The PVC morphology and its target. A. The 12
leads ECG showed the PVC morphology, which indicated its origin of left
ventricular anterior papillary muscle. B. The earliest
activation site of the PVC was located at the left ventricular anterior
papillary muscle (31ms ahead the surface QRS wave).
Figure 2 . The last retrograde transaortic manipulation. After
several attempts, the mapping catheter was finally introduced into the
left ventricle. Noted that the excessive contact force was encountered
during the retrograde transaortic manipulation (A-D).
Figure 3. The cervical computed tomography angiography. Noted
that the anomaly left vertebral artery is directly originated from the
aortic arch (red arrow).
Figure 4. Acute left cerebellar infarction. Cranial magnetic
resonance imaging (T1W1, T1W2 and DWI) confirmed acute left cerebellar
infarction.
supplementary video. The excessive contact force and the
retrograde transaortic manipulation. After several attempts, the mapping
catheter was finally introduced into the left ventricle. The excessive
contact force was encountered during the retrograde transaortic
manipulation from 12 seconds to 16 seconds of the video.
