BACKGROUND: Coronary bifurcation lesions (CBL) are associated with lower procedural success, worse postprocedural outcomes, and greater unplanned repeat revascularization. We sought to better understand the impact of Impella support in patients undergoing percutaneous coronary intervention (PCI) of CBLs.
METHODS: We used data from the cVAD PROTECT III study (NCT04136392), an FDA-audited, single-arm study of patients undergoing high-risk PCI with Impella support, to examine the outcomes of patients undergoing PCI of CBLs. Patients with a Medina classification of 1.1.1, 1.0.1, or 0.1.1 were considered to have a true CBL, and were compared to patients with nontrue CBLs and/or no CBLs. The primary outcome was the rate of CEC-adjudicated major adverse cardiac and cerebrovascular events (MACCE: composite of all-cause death, myocardial infarction, stroke/transient ischemic attack, and repeat revascularization) at 90 days. Cox proportional hazards regression models were adjusted for age, sex, left main disease, and triple vessel disease.
RESULTS: Of 1,044 patients, 523 had at least one true CBL treated. Baseline characteristics were comparable between groups except for age which was higher in patients with CBLs. Patients with CBLs had a significantly higher pre-PCI SYNTAX scores and number of treated lesions, more left main disease and triple vessel disease, and longer procedure duration. There was no difference in post-PCI SYNTAX score, PCI-related complications, or failure to achieve angiographic success. After adjustment for potential confounders, patients with CBLs had similar rates of 90-day MACCE.
CONCLUSIONS: While patients with CBLs undergoing Impella-supported high-risk PCI had higher complexity, there were similar rates of PCI-related complications and 90-day MACCE.
