We report the occurrence of catheter tip erosion during use of a Rotablator, a rare but serious complication. A heavily calcified lesion of the right coronary artery ostium required use of a Rotablator, and the need for strong push led to the choice of an Amplatz Left guiding catheter. The traction of the catheter toward the ostium and the subsequent angle generated led to friction of the burr against the catheter and the erosion of its tip. If judged essential to get strong support, the Amplatz catheter should be used with caution in this setting.
