				        	Objective This study was conducted to investigate the clinical outcomes and safety of percutaneous coronary intervention (PCI) to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction. Methods Twenty-seven patients with severe left ventricular systolic dysfunction (ejection fraction≤35%) undergoing PCI were included. All the patients received PCI only to the single-opened vessel lesion under the conditions of: (1) There were limitations to open chronic total occlusion (CTO);(2) Single-opened vessel lesion was not calcified and tortuous. Clinical outcomes, including success rate of PCI, changes of symptoms in-hospital, brain natriuretic peptide (BNP) and left ventricular ejection fraction (LVEF) pre-and one week post-PCI, the major adverse cardiac events (MACE, including death, myocardial infarction and target vessel revascularization) at 30-days after discharged were observed. Results The success rate of PCI was obtained in all 27 patients(100%), and all the patients received drug eluting stent implantation. The symptoms improvement occurred in all patients and the NYHA class improved from grade Ⅳto grade Ⅲin 22 patients(81.5%) in-hospital. Significant differences were noted in the mean BNP and LVEF between pre-PCI and one week post-PCI, BNP[(2699.6±1104.7) pg/ml vs. (737.0 ± 261.7) pg/ml, P<0.05],LVEF[(26.9±5.7)%vs. (36.0±3.41)%, P<0.05)]. No MACE happened in-hospital and at 30-days follow up. Conclusions PCI only to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction under the condition of limitations to open CTO is safe and can significantly improve clinical outcomes in-hospital and at 30-days follow up, but it must be emphasized that single-opened vessel lesion not with obvious calcification and tortuosity.
