CHIP-CC Registry: A Prospective Multicenter Registry of Complex High-Risk PCI in China

This is a prospective, multicenter, observational registry designed to evaluate clinical outcomes in patients undergoing complex high-risk indicated percutaneous coronary intervention (CHIP-PCI) in China. Eligible patients will be adults with complex coronary artery disease and severely reduced left ventricular function, or reduced left ventricular function with severe mitral regurgitation, who are considered by the heart team to have an indication for coronary revascularization but are at high risk for coronary artery bypass grafting or decline surgical revascularization. The registry will collect baseline clinical characteristics, coronary angiographic and procedural data, use of intravascular imaging or physiological assessment, revascularization strategy, mechanical circulatory support, peri-procedural complications, laboratory and echocardiographic data, and follow-up outcomes. The primary endpoint is all-cause mortality at 1 year after PCI. Secondary endpoints include major adverse cardiovascular events, cardiac death, myocardial infarction, target vessel revascularization, heart failure hospitalization, major bleeding, and quality-of-life measures. The study also aims to identify prognostic factors and develop a risk prediction model for patients undergoing CHIP-PCI.
