Brief Summary

Patients with coronary artery disease and undergoing high-risk percutaneous coronary intervention (PCI) are at increased risk of hemodynamic instability and poor outcomes. Mechanical circulatory support (MCS) devices may offer hemodynamic stabilization during PCI, potentially improving short- and long-term outcomes. The study rationale is to investigate the safety and clinical efficacy of temporary MCS with the iVAC 2L transaortic device in high-risk percutaneous coronary intervention. The transaortic system for short-term circulatory support with pulsatile blood flow iVAC 2L consists of an external membrane pump, a 17Fr diameter catheter for reversed blood flow (intake cannula) with a patented two-way rotary valve. The pump has two chambers, one for blood and one for helium, separated by a flexible diaphragm. The blood chamber connects to the catheter and the air chamber connects to a standard IABP console. The bi-directional valve is located 72 mm from the aspiration tip of the catheter and determines the direction of blood flow. The catheter is advanced retrogradely through the common femoral artery so that the tip is located in the left ventricular (LV) cavity and the valve is in the ascending aorta. Synchronized with the cardiac cycle via ECG, the device draws blood from the LV into the pump chamber during systole and ejects blood from the pump into the ascending aorta during diastole. The primary composite outcome is all-cause mortality, including acute myocardial infarction, stroke and TIA during hospitalization and at Day 360 of follow-up, expressed as a percentage of total patients.

Outcome Measures

Primary Outcomes (1)

  • All-cause mortality

    Constitutes one of the components of the MACCE composite endpoint: all-cause mortality, acute myocardial infarction, stroke or transient ischemic attack (TIA), and repeat revascularization (PCI or CABG).

    At day 7 after PCI or at discharge, if earlier. At day 360 of follow-up.

Secondary Outcomes (20)

  • Major vascular complications

    From the beginning of the PCI until its conclusion, the PCI is estimated to be from 40 to 270 minutes.

  • Incidence of recurrent myocardial infarction or reinfarction

    During the 360-day follow-up period

  • Angiographic failure

    Immediately after PCI.

  • Incidence of intraprocedural complications

    From the beginning of the PCI until its conclusion, the PCI is estimated to be from 40 to 270 minutes.

  • Left ventricular myocardial function

    At day 7 after PCI or at discharge, if earlier.

  • +15 more secondary outcomes

Study Arms (1)

Safety and clinical efficacy of temporary MCS with the iVAC 2L transaortic device in high-risk PCI

EXPERIMENTAL

100 pts with coronary artery disease with indications for High-Risk Percutaneous Coronary Intervention and no contradictions for the placement of the iVAC2L.

Device: iVAC 2L

Interventions

iVAC 2LDEVICE

The goal of this study is to investigate the safety and clinical efficacy of temporary mechanical support system with the iVAC 2L transaortic device in high-risk percutaneous coronary intervention (PCI) in Russia and Belarus. The POTOK trial will include patients with indications for elective, urgent and emergency PCI.
