Abstract only Introduction: Left main disease (LMCA) is a known risk factor for patients’ poor outcomes. Percutaneous revascularization of LMCA in heart failure patients is associated with a particularly high periprocedural risk. Percutaneously introduced left ventricle assist devices (pLVAD) are a potential tool to improve patient outcomes in these high-risk procedures. Hypothesis: Our study aimed to assess short-term clinical outcomes of protected left main percutaneous coronary intervention with the use of a pLVAD. Methods: A prospective registry of patients with chronic heart failure, undergoing protected LMCA PCI included 66 patients, 89% male, the median age of 71.5 y.o, 40 (60.6%) after prior myocardial infarction, 31 (47%) after prior PCI and 12 (18.2%) after CABG, with CTO RCA in 17 (25.6%) of cases. Percutaneous LVAD was used in all patients, 72% access site was the right femoral artery, additional plaque modification techniques were used in 46 (69.7%) patients, IVL was applied in 25 (37.9%) of cases and high-speed rotational or orbital atherectomy was used in 21 (31.2%) of cases. Median of 3 [2;4] DES was implanted. Results: During the in-hospital follow-up, a significant improvement of the left ventricle ejection fraction was observed (median LVEF 30% post PCI vs22% at baseline, p
