We report a case series of this complication and also review the possible mechanisms, such as kokesi phenomenon or insufficient pecking motion with decreased rotational speed. We also review the potential techniques ever proposed to rescue this complica-tion percutaneously, including simple manual traction, balloon dilation to release the trap, snaring the burr as distal as possible for forceful local traction and wedging the burr with a child catheter to facilitate retrieval. Gentle pecking motion of the burr for sufficient ablation and shortening the run less than 15 s may avoid such complications. Interventional cardiologists using the rotablator should be familiar with the tips and tricks to avoid and rescue this complication.展开更多

Most patients have experienced symptoms for more than 15 years. Massive calcification of the left atrium generality spared the interatrial septum in the previous studies. However, to our knowledge, fewer than five cases have presented as full left atrial calcification （Table）.展开更多
