Rotational Atherectomy Plus Intravascular Lithotripsy Versus Intravascular Lithotripsy Alone for Coronary Calcified Nodules: The NODULE-SHOCK Trial

JACC Cardiovasc IntervPublished single-center randomized trial

Authors' conclusion

RA plus IVL increased final stent area vs IVL alone in CN lesions, whereas maximum IVL pulses did not significantly increase final stent area compared with operator-determined pulses in severe calcification without CNs. These findings warrant validation in larger multicenter trials with clinical endpoints.

Study context

Population
Patients with optical coherence tomography-defined coronary calcified nodules (CNs) (Cohort A) and patients with severe calcification without CNs (Cohort B)33 per group in Cohort A, 27 per group in Cohort B · Cohort A 66 (55%) · Cohort B 54 (45%)
Participants
120 patients
Comparison
Cohort A: Rotational atherectomy (RA) plus intravascular lithotripsy (IVL) vs IVL alone; Cohort B: maximum vs operator-determined IVL pulses
  • RA plus IVL (Cohort A)n = 33
  • IVL alone (Cohort A)n = 33
  • Maximum IVL pulses (Cohort B)n = 27
  • Operator-determined IVL pulses (Cohort B)n = 27
Primary endpoint
Minimum stent area (MSA) at the CN site in Cohort A and at the maximum calcium arc site in Cohort B
