Keywords: Complex and High-risk Coronary Intervention (CHIP), Coronary and Hemodynamic support

Background:
Percutaneous ventricular assist devices (pVAD) are frequently used for hemodynamic support during complex high risk and indicated percutaneous coronary interventions (CHIP-PCI). Notwithstanding benefits of complete revascularization (CR), outcomes following complete- vs target-lesion revascularization (TR) during pVAD assisted CHIP-PCI remain unknown.

Methods:
From 06/2018 to 08/2020, 75 consecutive patients underwent pVAD assisted CHIP-PCIs at a single academic institution. Major adverse cardiac events (death, MI, stroke, 30 day rehospitalization, repeat revascularization) were evaluated at 30 days according to revascularization strategy (CR vs. TR).

Results:
The median age of study population was 77 (IQR 71,82) years, 69% were males, 49% had diabetes, and 61% had left main disease. Clinical Frailty Score was ≥ 6 in 2/3 ofpatients. Of the 75 patients who received pVAD (Impella: 97%; TandemHeart: 3%), 51% received CR and 49% underwent TR. Patients with TR had lower LVEF (30% vs 35%; p=0.023), higher SYNTAX 1 (38 vs 31; p=0.005), SYNTAX II (59 vs 50; p<0.001), and baseline PA diastolic pressures (31 vs 23 mm Hg; p=0.033). CR was associated with lower 30-day MACE compared to TR (21.1% vs 43.2%, p=0.049), driven primarily by a reduction in stroke (0% vs 18.9%, p=0.005). No differences in 30-day survival, acute kidney injury, bleeding and vascular complications were noted (Figure).

Conclusions:
In this study population, CR during pVAD assisted CHIP-PCI was associated with reduced 30-day MACE compared to TR. The extent to which differences in baseline characteristics may influence MACE during follow-up merits further investigation
