Brief summary

The primary purpose of this clinical trial is to evaluate the safety and efficacy of the percutaneous left ventricular assist system versus extracorporeal membrane oxygenation (ECMO) for circulatory support during high-risk PCI.

Detailed description

This prospective, multi-center, randomized controlled clinical trial of the Percutaneous Ventricular Assist System is designed to measure the incidence of freedom from major adverse cardiovascular and cerebrovascular events (MACCE) at 30 days after PCI.

Interventions

DEVICEPercutaneous Ventricular Assist System

Percutaneous Ventricular Assist System provides intraoperative circulatory support during high-risk PCI.

ECMO provides intraoperative circulatory support during high-risk PCI.

Incidence of freedom from major adverse cardiovascular and cerebrovascular events (MACCE)30 days after procedureMACCE defined as death, myocardial infarction, stroke, and target vessel revascularization.

Secondary

MeasureTime frameDescription
Incidence of death30 days, 90 days after procedureRate of all-cause death during the trial.
Incidence of myocardial infarction30 days, 90 days after procedureRate of patients with myocardial infarction during the trial.
Incidence of stroke30 days, 90 days after procedureRate of patients with stroke during the trial.
Incidence of target vessel revascularization30 days, 90 days after procedureRate of patients with target vessel revascularization during the trial.
Incidence of need for cardiac operation or thoracic or abdominal vascular operation or vascular operation for limb ischemia30 days, 90 days after procedureRate of patients with unplanned cardiac operation or thoracic or abdominal vascular operation or vascular operation for limb ischemia during the trial.
Incidence of acute kidney injury Remove30 days, 90 days after procedureRate of patients with acute kidney injury during the trial.
Incidence of cardiopulmonary resuscitation or ventricular arrhythmia requiring cardioversion30 days, 90 days after procedureRate of patients with cardiopulmonary resuscitation or ventricular arrhythmia requiring cardioversion during the trial.
Procedural success rateImmediately after procedureProcedure success is defined as (1) Technical success; (2) Freedom from serious in-hospital procedural complications
Incidence of severe hypotension30 days, 90 days after procedureRate of patients with severe hypotension during the trial. Severe hypotension defined as systolic blood pressure or augmented diastolic pressure (whichever is greater) \<90 mmHg for ≥5 min requiring inotropic/pressor medications or IV fluid.
Incidence of freedom from major adverse cardiovascular and cerebrovascular events (MACCE)90 days after procedureRate of patients with freedom from major adverse cardiovascular and cerebrovascular events (MACCE) during the trial. MACCE defined as death, myocardial infarction, stroke, and target vessel revascularization.
Hemodynamic support success rate during PCI procedureDuring procedureHemodynamic support success is defined as (1) Percutaneous mechanical circulatory assist device was delivered and activated successfully, and withdrawn from the body successfully; (2) Hemodynamic stability during procedure (defined as mean arterial pressure (MAP) \<60mmHg for no more than 10 minutes during the PCI procedure and additional pressor medication is not required).
Technical success ratemmediately after procedureTechnical success is defined as (1) Hemodynamic support success; (2) Coronary revascularization success (defined as ①residual stenosis \<30% after coronary stent implantation; ②restoration of TIMI anterograde flow of II or III).
Change in LVEF compared to baseline30 days, 90 days after procedureLVEF is assessed at 30 days, 90 days after procedure, and compared to baseline
Improvement in cardiac function30 days, 90 days after procedureCardiac function is evaluated based on NYHA classification and compared to baseline. New York Heart Association (NYHA) Functional Classification includes four categories(CLASS I to CLASS IV, higher class mean a worse outcome) based on physical activity limitations.
Evaluation of Experimental device performanceImmediately after procedurePerformance evaluation includes the catheter pump and extracorporeal control device (For each assessment: 1-10 points;1=worst, 5=moderate, 10=best).
