Abstract
Implantation of leadless pacemaker is efficacy and safety compared with the traditional pacemaker in structurally normal hearts. However, delivery experience of leadless pacemaker in patients with severe right heart enlargement remains limited. We present the rare case of a patient with giant right heart and moderate to severe tricuspid regurgitation implanted with a leadless Micra transcatheter pacemaker system. The extension of the Micra delivery catheter can be improved by using a single‐loop snare on the catheter proximal to appropriate right ventricle (RV) pacing position. The snare‐kissing‐catheter technique can aid in successful deployment in the setting of challenging right heart enlargement.
