High-Risk Chronic Total Occlusion Percutaneous Coronary Interventions Assisted With TandemHeart.

Background: Hemodynamic support is increasingly utilized to avoid hemodynamic collapse during high-risk chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Intermediate-term outcomes of Tandem Heart (TH)-supported CTO-PCI have not been previously reported.

Methods: We retrospectively evaluated procedural and clinical outcomes in consecutive patients undergoing TH-assisted CTO-PCI at our institution from April 1, 2016 to January 30, 2019.

Incidence and prognosis of vascular complications after percutaneous placement of left ventricular assist device.

Objective: Mechanical assist devices have found an increasingly important role in high-risk interventional cardiac procedures. The Impella (Abiomed Inc, Danvers, Mass) is a percutaneous left ventricular assist device inserted through the femoral artery under fluoroscopic guidance and positioned in the left ventricular cavity. This study was undertaken to assess the incidence of vascular complications and associated morbidity and mortality that can occur with Impella placement.
