A case of endocardial dissection caused by Micra implantation

Figures

• 

  Fig. 1. Preoperative right ventriculogram showed an intact endocardium. (A. Right anterior oblique position; B. Left anterior oblique position)

• 

  Fig. 2. Contrast agent was retained after injection, forming a pocket-type structure with an opening diameter of approximately 25 mm and an axial length of approximately 20 mm

• 

  Fig. 3. Extravasation of contrast into the pericardial cavity when angiography was performed near the area of residual contrast. (A) Right anterior oblique position; (B) Left anterior oblique position)

• 

  Fig. 4. Release the Micra at a high intervals after adjusting the position. (A. Right anterior oblique positioning image; B. Left anterior oblique positioning image; C. Left anterior oblique fluoroscopic Micra final release parallel to the image of the pericardial perforator tube.)

• 

  Fig. 5. Postoperative cardiac echocardiography revealed an endocardial tear in the apical region of the right ventricle

• 

  Fig. 6. Cardiac CTA was performed 3 days after surgery and showed an endocardial defect in the region of the median septal sulcus of the right ventricle

• 

  Fig. 7. Micra release cup. The visible edge of the cup has an outwardly rolled contour,, but the edge is still relatively sharp considering that it is only 0.3 mm thick
