Percutaneous Ventricular Restoration with a Partitioning Device for Ischemic Heart Failure Treatment.

PURPOSE OF THE REVIEW: Percutaneous ventricular restoration with a ventricular partitioning device (VPD) is a novel minimally invasive procedure designed to restore the left ventricular (LV) shape by isolating the infarcted and aneurysmal LV apex from remainder of the cavity in heart failure patients with severely reduced LV ejection fraction. In this review, we perform an in-depth analysis of the design and purpose of the VPD and review the available clinical data, with special attention to hemodynamics, outcomes, and complications.

RECENT FINDINGS: PARACHUTE trials have shown >90% procedural success rate of VPD implant. Heart failure patients had improvement in hemodynamics (reduction in LV volumes and increase in LV ejection fraction) and functional status (6-min walking distance and quality of life scores) after the VPD implant. Optimal implant position is necessary to obtain a good clinical outcome. Percutaneous VPD implantation has thus far been a safe intervention capable of improving surrogate markers of heart failure but there is still a need to develop more durable devices with a long-lasting hemodynamics effect.
