Tunnelling a calcified total occlusion.

Among the complex and high-risk coronary intervention cases, a calcified total occlusion of coronary artery poses a great challenge. We came across a 48 years old male who had calcified total occlusion of the right coronary artery. The chronic total occlusion was crossed using Nic-Nano balloon and the calcific plaque was modified using intravascular lithotripsy as an alternative technique to rotational atherectomy which we felt as an evolving alternative approach to treat the calcified total occlusion.
