NCT06127927

Brief Summary

Imported Impella The price is relatively expensive and difficult for ordinary patients to afford. In order to better meet the growing clinical needs in China, Anhui Tongling Bionic Technology Co., Ltd. has developed an interventional left ventricular assist system. The test device was tested in preclinical animals It has shown good effectiveness and safety. Through the implementation of this clinical trial, the interventional left ventricular assist system The safety and effectiveness of the system for hemodynamic support in patients with cardiogenic shock have led to further development of this product in the country.

Outcome Measures

Primary Outcomes (2)

  • Survival rate of subjects at discharge or 30 days after weaning from ventilator (whichever is longer)

    Survival was defined as recovery of cardiac function or survival to bridging therapy; Recovery of cardiac function was defined as no need for any mechanical support or IABP assistance 30 days after removal of the invasive left ventricular assist system or at discharge (whichever was longer). Survival to bridging therapy was defined as survival to the induction of anesthesia for heart transplantation or placement of an implantable ventricular assist device.

    30days

  • The incidence of major adverse events at discharge or 30 days after weaning (whichever is longer)

    Major adverse events included death and stroke.

    30days

Secondary Outcomes (2)

  • hemodynamic indicators

    30days

  • Successful device placement and technical success

Study Arms (2)

Interventional Left Ventricular Assist System Pre-trial

EXPERIMENTAL

The design of the first phase pre-trial clinical study will involve a total of 6 subjects. The survival rate of subjects before discharge or 30 days after weaning was the main effectiveness evaluation indicator, and the safety and effectiveness of the test device were preliminarily evaluated. All SAE events during the study will be reviewed by CEC experts. According to the expert review opinions, if no unexpected serious complications and product defects are found, the Formal Research phase will be started.

Device: Interventional Left Ventricular Assist System

Interventional Left Ventricular Assist System Formal Research

EXPERIMENTAL

A formal clinical trial to evaluate the effectiveness and safety of interventional left ventricular assist system for hemodynamic support in patients with cardiogenic shock through a prospective, multicenter, single-group target value study.The total number of patients enrolled in this study is planned to be 54. This sample size is calculated according to statistical principles, combining the research hypothesis and the estimate of the expected level of efficacy. The sample size calculation is based on the main efficacy index and the main safety index. Since it is set according to the common evaluation index, the sample size is calculated for the two main evaluation indicators separately, and the largest one is used as the final sample size of this trial.
