Comprehensive Optical Coherence Tomography-Guided RotaTripsy for Massive Coronary Calcified Nodule: A Decision-Making Approach.

ABSTRACT:

Objectives

We aim to describe the step-by-step optical coherence tomography-guided rotational atherectomy and intravascular lithotripsy for treating substantial coronary calcified nodules.

Key steps

These include initial rotational atherectomy with a 1.5-mm burr, multiple optical coherence tomography imaging studies to assess lesion morphology, upsizing the rotational burr to 2.0 mm for further debulking, performing adjunctive intravascular lithotripsy with a 3.5-mm Shockwave balloon (Shockwave Medical Inc), and final stent deployment and optimization.

Potential pitfalls

Potential complications include burr entrapment during rotational atherectomy, inadequate lesion modification with initial rotational atherectomy, and failure to achieve deep calcium fractures leading
