Abstract

Aims: Recent evidence suggests that IVUS use in PCI all-comers may improve clinical outcomes. To date, no study investigated the effect of IVUS use on outcomes in patients with complex coronary lesions requiring treatment with rotational atherectomy and subsequent DES implantation. Methods and results: In this retrospective study total of 361 patients with at least one coronary lesion treated with rotational atherectomy and subsequent DES implantation were recruited between April 2002 and August 2013. Follow-up outcomes [major adverse cardiovascular events (MACE); death, myocardial infarction (MI), target lesion revascularisation (TLR), non-TLR target vessel revascularisation (TVR)] were recorded. In 99 (27.4%) cases, IVUS was used whereas in 262 (72.6%) no IVUS was performed. Between the two groups (no IVUS vs. IVUS use) there was no difference in gender (males; 76.7% vs. 82.8%, p=208), mode of presentation (ACS: 35.1% vs. 30.4%, p=0.422), diabetes prevalence (42% vs. 30.6%, p=0.262) or rate of previous PCI (43.5% vs. 43.4%, p=0.989). Patients in the IVUS group were slightly older (68.4±9.7 vs. 70.6±9.0, p=0.046) with lower rates of previous CABG (30.1% vs. 18.8%, p=0.033). Regarding disease severity between groups (no IVUS vs. IVUS, respectively), a similar prevalence of unprotected LM (3.4% vs. 6.1%, p=0.259), three vessel disease (51.6% vs. 52.1%, p=0.496), bifurcation lesions (20.2% vs. 15.7%, p=0.252), aorto-ostial lesions (3.4% vs. 3.5%, p=0.765) and chronic total occlusions (9.8% vs. 8.6%, p=0.667) was observed. However, according to angiographic type, more complex lesions (type C: 62.0%% vs. 81.4%, p<0.001) were treated in the IVUS group patients. There was no difference in intra-aortic balloon pump counterpulsation (no IVUS vs. IVUS; 7.3% vs. 7.1%, p=0.953) or balloon type used for dilatation after rotablation (p=0.741). In the IVUS group, larger final burr (p=0.015) and larger post stenting dilatation balloon sizes (p=0.003) were used. No signifi
