Coronary Calcified Nodule Management With Rotational Atherectomy Plus Shockwave Intravascular Lithotripsy vs. Intravascular Lithotripsy Alone: A Prospective, Randomized Trial (NODULE-SHOCK)
Annapoorna Kini
Summary
The NODULE-SHOCK trial is a prospective, investigator-initiated, single-center, randomized controlled trial designed to compare the efficacy of intravascular lithotripsy (IVL) with or without rotational atherectomy (RA) in patients with coronary calcified nodules (Cohort A), and operator-determined vs maximum IVL pulses in patients with non-nodular severe coronary calcium (Cohort B).
Description
The trial consists of two cohorts: * Patients with calcified nodules (CN) (Cohort A) * Patients with non-nodular severe coronary calcium (Cohort B) Randomization will occur as follows: * Rotational atherectomy followed by intravascular lithotripsy (IVL) or IVL alone for lesion preparation prior to stenting (Cohort A). * Operator-determined or maximum IVL pulses prior to stenting. (Cohort B) The trial is designed to compare two calcium modification strategies in each cohort with regard to the primary endpoints of post-procedural minimum stent area assessed by optical coherence tomography at…
