Micro-axial Flow Pump-Supported PCI in Complex Coronary Artery Disease With Ischemic LV Dysfunction (PIVOT)

June 28, 2026 updated by: China National Center for Cardiovascular Diseases

Micro-axial Flow Pump-Supported PCI Plus Optimal Medical Therapy Versus Optimal Medical Therapy Alone in Complex Coronary Artery Disease With Ischemic LV Dysfunction: A Prospective, Multicenter, Randomized Controlled Trial

Based on a multi-center randomized controlled study, this research aims to evaluate the efficacy and safety of interventional therapy supported by the CorVad percutaneous left ventricular assist system (Micro-axial Flow Pump） for patients with complex coronary heart disease (CHD) complicated by ischemic left ventricular systolic dysfunction. Through a prospective, multi-center, open-label 1:1 randomized controlled trial, a total of 452 patients with severe ischemic systolic dysfunction and complex coronary lesions were enrolled. The study compared the 12-month incidence of Major Adverse Cardiovascular and Cerebrovascular Events (MACCE) between patients who received interventional therapy supported by the CorVad percutaneous left ventricular assist system in addition to the most appropriate medical therapy and those who only received the most appropriate medical therapy. This was done to test whether the interventional therapy supported by the CorVad percutaneous left ventricular assist system can improve the prognosis of patients with severe ischemic systolic dysfunction and complex coronary lesions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
