Background: The aim of the present study was to investigate whether
intra-aortic balloon pump (IABP) support was associated with better outcomes
after rotational atherectomy (RA) in patients with multivessel disease and low
left ventricular ejection fraction (LVEF). Methods: Between January 2015
and December 2021, 596 consecutive patients with severely calcified coronary
lesions who underwent elective RA were retrospectively enrolled. Of these, a
total of 156 patients were included in this study based on the propensity score
matching and divided into two groups according to elective IABP insertion (IABP
group, n = 80) or no insertion (non-IABP group, n = 76) before the RA procedure.
The primary endpoints were procedural success and major adverse cardiovascular
events (MACE) before discharge. The secondary endpoints were mortality and
readmission due to heart failure (HF) during 90-day and 180-day follow-up.
Results: 77 of patients (96.3%) in the IABP group and 72 of patients
(94.7%) in the non-IABP group got procedural success (p = 0.714),
separately. We had not observed significant differences in periprocedural
complications except for less frequent hypotension in the IABP group (p
