Ep. 386 The PERT Approach: Innovating on Acute PE Management with Dr. Robert Lookstein

In this episode, host Dr. Chris Beck interviews Dr. Robert Lookstein about the pulmonary embolism response team (PERT) approach for treating acute pulmonary embolisms (PE). Dr. Lookstein is a practicing interventional radiologist in New York City at Mount Sinai Icahn School of Medicine. --- CHECK OUT OUR SPONSOR Penumbra Lightning Flash https://www.penumbrainc.com/products/lightning-flash/ --- SHOW NOTES We begin the episode by learning how Dr. Lookstein became involved in the PE space and how acute PE management has evolved. Dr. Lookstein breaks down the PERT at Mount Sinai, PERTs at other academic institutions, and the core qualities of a strong PERT. He walks us through a typical PE presentation, the process of PERT activation, and the workup with risk stratification. Dr. Lookstein also shares a few physical examination pearls for evaluating patients with PE and teasing out acuity vs. chronicity of presentation . Dr. Lookstein and Dr. Beck discuss endovascular PE interventions - ultrasound accelerated thrombolysis (trade name: EKOS catheter, Boston Scientific), first generation and second generation thrombectomy systems. The doctors also cover how advancements in technology have made these large-bore thrombectomy devices easier to learn about and use. Looking towards the horizon, Dr. Lookstein shares what we can expect from third generation technologies. We highlight how the primary endpoint of the PERT is to relieve the strain and stabilize/preserve the function of the right ventricle, regardless of how much clot is removed/remains. The doctors discuss the possibility of combined treatment algorithms for PE and the clinical data that has guided PERTs (all linked in resources below). To conclude the episode, Dr. Lookstein shares follow-up, longitudinal care, and how to tackle clot-in-transit. --- RESOURCES PERT Consortium: https://pertconsortium.org/ Ultima Trial: https://www.bostonscientific.com/en-EU/medical-specialties/vascular-surgery/venous-thromboembolism-portal/pulmonary-embolism/clinical-data/ultima.html HI-PEITHO Trial: https://www.bostonscientific.com/en-EU/medical-specialties/vascular-surgery/venous-thromboembolism-portal/pulmonary-embolism/clinical-data/hi-peitho.html CANARY Trial: https://www.acc.org/Latest-in-Cardiology/Clinical-Trials/2022/10/25/19/42/CANARY PE-TRACT Trial: https://evtoday.com/articles/2023-feb/pe-tract-a-closer-look STORM-PE Trial: https://pertconsortium.org/storm-pe-trial/ PEERLESS II Trial: https://ir.inarimedical.com/news-releases/news-release-details/inari-medical-announces-peerless-ii-randomized-controlled-trial
