PERTcast

In this episode, we explore considerations in mechanical thrombectomy for pulmonary embolism, with particular emphasis on determining appropriate endpoints for concluding a procedure and the critical role of time and procedural efficiency. Key takeaways cover optimizing procedure duration, achieving meaningful reductions in pulmonary artery pressure and clot burden, and employing strategies to minimize or prevent blood loss throughout the intervention.

Episode 5: Dr. Rosovsky interviews Dr. Robert Lookstein about the new PERT Consortium Database!! Dr. Lookstein is a Professor of Radiology and Surgery at the Icahn School of Medicine at Mount Sinai.  Dr. Rosovsky is the Director of Thrombosis Research within the Division of Hemaology at Mass General Hospital. 

Episode 4: Dr. Rosenfield interviews Dr. Richard Channick on Post PE care! Dr Channick is the current PERT Consortium president and is the Director of the Acute and Chronic Thromboembolic Disease Program within the David Geffen School of Medicine at UCLA.  Dr. Rosenfield is Section Head of Vascular Medicine and Intervention at Mass General Hospital and past PERT president and founder. What happens after a PE? Following acute pulmonary embolism some patients do not return to their baseline and may suffer from what is called post PE syndrome. Some of these unfortunate patients develop chronic thromboembolic disease or chronic thromboembolic pulmonary hypertension Follow Up Clinic In clinic it's important to assess if patients have returned to their baseline of physical acitivity. If the answer is no, then go for objective testing First step may be getting a follow-up echocardiogram or repeat imaging CTA is extremely helpful for acute pulmonary embolism. CTA is less revealing for chronic pulmonary embolism. VQ scan is the most sensitive test for the chronic pulmonary embolism.  If VQ scan is normal 8 to 10 weeks following acute PE rhythm you do not have any chronic pulmonary embolism Following an abnormal VQ scan next steps should be --> evaluated for CTED or CTEPH. Define chronic thromboembolic pulmonary hypertension and its characteristics? CTED or CTEPH is a scar tissue forming in pulmonary vessels is not an acute clot. à higher degree of such vascular obstruction will lead to increase in PVR and eventually PHTN and RV dysfunction. CTED or CTEPH has distinct appearance on imaging: Chronic clot may have appearance of fibrous bands, webs or bands. Appearance is quite different than acute clot. Extremely high pulmonary artery pressure of about 80 or 90 millimeters of Hg suggest chronic right ventricular pressure overload. Bronchial collaterals on CTA may suggest a chronic process. Acute Vs Chronic Clot on Imaging: Acute clot will have a central occlusive appearance. Sometimes it is hard to differentiate. If patient has not been anticoagulated in the past you anticoagulate and do a follow-up in 8 to 10 weeks. Signs of RV hypertrophy on the echocardiogram also suggests a chronic process   Treatment of chronic thromboembolic pulmonary hypertension First-line of treatment is surgical. [It is complicated cardiac surgery that involves expert surgical team. It involves cardiopulmonary bypass, deep hypothermic arrest and needs and expertise.] Balloon pulmonary angioplasty growing evidence. RIOCIGUAT is the only approved drug for CTEPH. Macitentan has been studied but not approved. PDE inhibitors   also have been tried Upfront medical therapy should not delay the referral for the patients who potentially are surgical candidates. Types of chronic thromboembolic pulmonary disease  and surgical classification Four levels depend on whether the disease starts If the disease starts proximally it is easier for the surgeon to dissect. It depends where the chronic clots are involving the pulmonary vasculature. Level 1 disease: Proximal disease Level 2 disease: Lobar disease Level 3 disease segmental disease Level 4 disease sub-segmental disease Basics Concepts of Balloon Pulmonary Angioplasty (BPA) It involves dilating the narrowed pulmonary segments and improve with the primary pulmonary perfusion and reducing the pulmonary hypertension. First step is to do the pulmonary angiogram. Then match the perfusion defects with the VQ scan.  Work as a team. Goal is not to over distend the pulmonary vasculature. Goal is just to break up the scar or the fibrous tissue and increase distal perfusion. Vascular stenting is not performed usually. BPA is a staged procedure. The session can last anywhere between 2-3 to 12-13 sessions. Each session is 2 to 3 hours involves fair amount of radiation and the contrast. Pulmonary hemorrhage is a very serious complication; BPA has a learning curve.  

Episode 3: James Horowitz interviews Rachel Rosovsky on DOACs. Dr. Rosovsky is the Director of Thrombosis Research in the Division of Hematology at Mass General Hospital. She is also an Assistant Professor at Harvard and a member of the Board of Directors of the PERT Consortium.  Dr. Horowitz is the Director of the CCU at NYU Langone Health and the Co-Chair of the Interdisciplinary Resuscitation Committee. He is also an Assistant Professor or Medicine and a member of the Board of Directors of the PERT Consortium. Directly acting oral anticoagulants.   FDA approved DOACS: Xarelto (rivaroxaban), Eliquis (apixaban), Savasya (edoxaban), Pradaxa (dabigatran). All DOACs have similar efficacy in terms of VTE occurrence and better safety profile compared compared to Coumadin. MOA: Dabigatran: directthrombin inhibitor.   Rest of the DOACs: factor X inhibitors. DOACS usually do not need monitoring. Most common interaction noted with drugs like ketoconazole (CYP3A4). Dosing: Dabigatran and Edoxaban: Overlap with parenteral enoxaparin for 5 to 10 days is needed. Apixaban and Rivoraxaban: Need loading dose. For apixaban it is 10 mg 2 times a day for 7 days followed by 5 mg 2 times a day.  Rivaroxaban: 15 mg 2 times a day for 21 days followed by 20 mg once a day. (Xarelto need to be taken with food) Only 55% of the patients with Coumadin remain in therapeutic range. Drug reversal agents for DOACs Dabigatran reversal: Idarucizumab Xarelto and Eliquis reversal: Andexenat Alpha. Factors in deciding candidacy for DOACs: DOACs in patients with Child-Pugh score B/C cirrhosis should not be used. Renal failure with CrCl 120 kg, based on ISTH guidelines. (higher the BMI may have increased risk of bleeding with better efficacy, potentially due to absorption issues-- levels can fluctuate) Drug monitoring for DOACs: No standardized methods. Not routinely done. It should be considered in patients with extremes of weight and patients who have gone gastric/bariatric surgeries, because all DOACs are absorbed get into upper GI tract. Pregnancy and Venous thromboembolism: No DOACs in pregnancy. Enoxaparin is the treatment of choice -1 mg/kg every 12 hours up to week 36 followed by changing them to unfractionated heparin. (subcutaneous calculated dose). Patients who had prior DVTs/PEs and become pregnant may need prophylactic dose of enoxaparin (40 mg subcutaneous once a day) Cancer and VTE: VTE is a second leading cause of death in cancer patients. Drug of choice was enoxaparin over warfarin. Edoxaban Vs Enoxaparin: Edoxaban with less recurrent VTE, but worse bleeding profile (most bleeds in gastric cancer patients) Rivaroxaban Vs Enoxaparin: Rivaroxaban with less recurrent VTE, but worse bleeding profile (most bleeds in gastric cancer) Cancer patients who may not be good candidate: a) GI cancer b) needing many procedures c) liver/renal failure d)brain mets.  Provoked vs Unprovoked and extended a/c: Unprovoked PE: Two-year risk of recurrence 25% or higher. Provoked by surgery [mainly orthopedic surgery, pregnancy, long hospital stay]: risk of recurrence 1% at one year, 3% at 5 years. Flying is a weak risk factor to be considered as provoked. Amplify-Ext trial: 70% decrease risk of recurrence with low dose apixaban without an increased risk of bleeding in unprovoked VTE. Einstein Choice trial: 70% decrease risk of recurrence with low dose rivaroxaban without an increased risk of bleeding. 60% of patients had provoked VTE with ongoing risk factors. (i.e. Obese patients, patients who are immobile, and are still immobile). Cancer screening following PE: 5-10% of patients with VTE would be diagnosed with malignancy in next 5 years. Recommendation is to do age appropriate cancer screening. Valves and DOACS: (increase risk of ischemic events)   Reference: Rali P, Gangemi A Moores A et al.
