Abstract

OBJECTIVE: To study outcomes with use of percutaneous mechanical circulatory support (MCS) devices in chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

METHODS: We examined characteristics and outcomes of 1598 CTO-PCIs performed from 2012-2017 at 12 high-volume centers.

RESULTS: Patient age was 66 ± 10 years; 86% were men. An MCS device was used electively in 69 procedures (4%) and urgently in 22 procedures (1%). The most commonly used elective MCS device was Impella 2.5 or CP (62%). Compared to patients without elective MCS, patients with elective MCS had higher prevalence of prior heart failure (55% vs 29%; P

CONCLUSION: Elective MCS was used in 4% of patients undergoing CTO-PCI. Despite more complex clinical and angiographic characteristics, elective use of MCS in high-risk patients is associated with similar technical and procedural success rates, but higher risk of complications, compared to cases without elective MCS.
