SoCCC Pre-Rounds: Bite-Sized Critical Care Cardiology Topics Delivered By Experts

The Story of DanGer Shock and the Future of the Microaxial Flow Pump with Dr. Jacob Møller

After more than two decades without a major positive randomized trial in cardiogenic shock, is the evidence finally catching up to the technology?  In this episode of SoCCC Pre-Rounds, Dr. Simon Parlow sits down with Dr. Jacob Møller, critical care cardiologist and professor at the University Hospital Copenhagen, to unpack microaxial flow pumps and the landmark DanGer Shock trial. Dr. Møller shares how persistence, collaboration, and a bit of luck helped drive a breakthrough in a field that has long needed one. They explore how these devices work at the bedside, from unloading the left ventricle to reducing myocardial oxygen demand, and what that means in real-world care. The conversation also dives into the challenges of running a high-stakes trial in critically ill patients, along with practical insights on patient selection, complications, lactate trends, and weaning strategies. It’s a sharp look at one of the most important recent advances in cardiogenic shock and where clinicians are still forced to operate without clear evidence. * Microaxial flow pumps unload the left ventricle: By reducing preload and stroke work, they may lower myocardial oxygen demand and support recovery in shock states. * The DanGer Shock trial changes the landscape: It’s the first major positive randomized trial in cardiogenic shock in over 20 years, targeting a highly selected STEMI population. * Patient selection is everything: Only a small fraction of shock patients were eligible, highlighting how precise clinicians must be when applying this therapy. * Weaning starts earlier than we thought: The most critical window may be the first 12–24 hours, with earlier reassessment for device removal. * Evidence is still evolving: Outside of trial populations, clinicians must rely on judgment when considering use in non-STEMI or non-ischemic shock. * [00:00] Introduction to SoCCC Pre-Rounds * [00:57] Live from ACVC 2026: introducing Dr. Jacob Møller * [01:15] What are micro axial flow pumps and how do they work? * [03:52] The origin and evolution of the DanGer Shock trial * [06:39] Trial results and why they were unexpected * [07:48] Expanding beyond STEMI: real-world patient selection * [09:44] Monitoring patients: lactate and hemodynamic trends * [10:20] Early management challenges and complications * [11:36] Rethinking weaning strategies * [12:05] Role of guideline-directed therapy during support * [12:57] Lessons from running a major clinical trial * [14:03] Building a research culture in critical care * [07:51] "After seeing the results of DanGer, we have probably become a little bit more liberal in using the device in other forms of ischemic, like non-STEMI shock." — Dr. Jacob Møller * [09:46] "We look at trajectories, and we look a lot at lactate. Lactate has to go down in these patients; otherwise, something is wrong." — Dr. Jacob Møller * [10:33] "You look at the trajectory, so if it goes from 1.5 and starts going down, then you know there's something wrong." — Dr. Jacob Møller * [13:57] "I'm working in a very small cardiac ICU; we only have seven beds, but we randomized more than 100 patients with out-of-hospital cardiac arrest every year." — Dr. Jacob Møller * Become a member of the Community: https://www.soccc.org/subscribe [https://www.soccc.org/subscribe] Dr. Jacob Møller * https://www.linkedin.com/in/jacob-eifer-m%C3%B8ller-1b2398300/?locale=en [https://www.linkedin.com/in/jacob-eifer-m%C3%B8ller-1b2398300/?locale=en] * https://www.rigshospitalet.dk/ [https://www.rigshospitalet.dk/] Dr. Simon Parlow * https://www.ottawaheart.ca/profile/parlow-simon [https://www.ottawaheart.ca/profile/parlow-simon] Supported By: This episode is made possible by unrestricted support from Zoll LifeVest [https://cardiac.zoll.com/patients/lifevest?utm_term=life%20vest%20cardiac&utm_campaign=Cardiac+-+LifeVest+Patients&utm_source=adwords&utm_medium=ppc&hsa_acc=3725084088&hsa_cam=22620204946&hsa_grp=184004443847&hsa_ad=755140542390&hsa_src=g&hsa_tgt=kwd-2422787973254&hsa_kw=life%20vest%20cardiac&hsa_mt=b&hsa_net=adwords&hsa_ver=3&gad_source=1&gad_campaignid=22620204946&gbraid=0AAAAADqfl7Q-s3_-V8Hkd__LS91jIXf69&gclid=CjwKCAjwsZPDBhBWEiwADuO6y4FsrFZuMqyJYSsOtaDxoS4MidynidBRdOuw34-wjC3TvENsvThC4xoC188QAvD_BwE]— thanks for keeping high-impact education free for our community.

Keeping It Cool: The Evidence, the Controversy, the Future of TTM with Dr. Andrea Elliott

In this episode of SoCCC Pre-Rounds, Dr. Balim Senman and Dr. Andrea Elliott, a cardiologist and critical care physician at the University of Minnesota, dive into the evolving landscape of targeted temperature management (TTM) after cardiac arrest. They explore how temperature control strategies have shifted from early hypothermia trials to modern fever-avoidance methods, with ongoing debates around TTM in critical care. Dr. Elliott discusses landmark studies like Bernard, HACA, TTM, Hyperion, and TTM2, highlighting their impact and limitations. The conversation delves into the real-world application of temperature targets, considering patient severity, neurologic injury, and the unique challenges posed by ECPR patients. Dr. Elliott also covers the physiological costs of hypothermia, common complications, and practical aspects of managing shivering, devices, and protocols. Whether you're a trainee or an experienced clinician, this episode offers evidence-based insights and practical guidance for optimizing post-arrest care. * TTM is for comatose survivors: Only patients who remain unresponsive after ROSC benefit; awake patients do not. * Fever prevention matters most: Trial data on hypothermia vs normothermia are mixed, but fever (>37.7°C) is consistently harmful and must be aggressively avoided. * One size does not fit all: Patients with longer downtimes or more severe neurologic injury may benefit more from active cooling. Allowing spontaneous hypothermia is reasonable. * ECPR patients are different: Prolonged CPR and ECMO-based temperature control make them physiologically distinct from patients in major TTM trials. In This Episode * [00:00] Introduction * [02:16] Historical background of TTM * [03:13] Early human studies and mechanisms * [04:17] Landmark trials Bernard and HACA * [06:06] TM1 Hyperion and TM2 trials * [10:25] Patient selection for TTM * [11:39] Personalized temperature targeting * [13:21] Management of hypothermic and normothermic patients * [15:47] TTM in ECPR and ECMO patients * [18:09] Drawbacks and risks of hypothermia * [19:19] Protocols and cooling devices * [21:59] ECPR-specific cooling techniques Notable Quotes * [16:04] "ECPR patients by definition have had refractory arrest, not attaining ROSC. So that 20- 25 minute time is blown out of the water. Our ECPR population has an average of 60 minutes of CPR time, so more than double. So the time for that neurologic injury is extensive." — Dr. Andrea Elliott * [18:43] "You can actually get into trouble if with some under-resuscitation and some patients, if you get them too cold too quickly, and so you'll have to give extra volume back."— Dr. Andrea Elliott * [22:37] "The most important thing is to make sure that you avoid fevers in our ECPR patients. We also use cooling towers, so we basically cool the fluid or the blood that is in the tubing outside of the patient so that it goes through a cooling bath."— Dr. Andrea Elliott Resources and Links * Become a member of the Community: https://www.soccc.org/subscribe [https://www.soccc.org/subscribe] Dr. Andrea Elliott * https://med.umn.edu/bio/andrea-elliott [https://med.umn.edu/bio/andrea-elliott] * https://www.linkedin.com/in/andrea-elliott-5575b4267/ [https://www.linkedin.com/in/andrea-elliott-5575b4267/] Dr. Balim Senman * https://www.linkedin.com/in/balim-senman-7561436b/ [https://www.linkedin.com/in/balim-senman-7561436b/] * https://x.com/BalimSenmanMD [https://x.com/BalimSenmanMD] * https://www.soccc.org/ [https://www.soccc.org/] Supported By: This episode is made possible by unrestricted support from Zoll LifeVest [https://cardiac.zoll.com/patients/lifevest?utm_term=life%20vest%20cardiac&utm_campaign=Cardiac+-+LifeVest+Patients&utm_source=adwords&utm_medium=ppc&hsa_acc=3725084088&hsa_cam=22620204946&hsa_grp=184004443847&hsa_ad=755140542390&hsa_src=g&hsa_tgt=kwd-2422787973254&hsa_kw=life%20vest%20cardiac&hsa_mt=b&hsa_net=adwords&hsa_ver=3&gad_source=1&gad_campaignid=22620204946&gbraid=0AAAAADqfl7Q-s3_-V8Hkd__LS91jIXf69&gclid=CjwKCAjwsZPDBhBWEiwADuO6y4FsrFZuMqyJYSsOtaDxoS4MidynidBRdOuw34-wjC3TvENsvThC4xoC188QAvD_BwE]— thanks for keeping high-impact education free for our community.

The POCUS Revolution: Why Echo Belongs in Every ICU with Dr. Hatem Soliman

In this episode of SoCCC Pre-Rounds, Dr. Simon Parlow is joined by Dr. Hatem Soliman, a leading expert in critical care echocardiography, for a deep dive into the game-changing role of point-of-care ultrasound or POCUS in resuscitation and cardiac intensive care. Together, they unpack how resuscitative echocardiography can help identify reversible causes of cardiac arrest, like pericardial tamponade or tension pneumothorax, and even guide real-time chest compression placement to improve CPR effectiveness. Dr. Soliman highlights two must-have views: the apical five-chamber for stroke volume and the short-axis great vessels view to assess RV function and pulmonary pressures. If you're looking to sharpen your bedside skills and bring more precision to your resuscitation toolkit, this episode is packed with insights you won’t want to miss. Key Takeaways * Move beyond the IVC: Hepatic, portal, and renal vein Doppler give a clearer picture of systemic venous congestion than IVC alone. * Cardiac output needs context: Doppler VTI can mislead unless combined with views like apical five-chamber and timing indices like isovolumetric contraction time. * Every echo parameter has a pitfall: Never interpret one measure in isolation; always integrate findings with clinical judgment. * His go-to views in shock? Apical 5 chamber (LVOT VTI) and parasternal short axis of great vessels (PA flow) to assess perfusion and RV afterload. In This Episode * [00:00] Introduction to the podcast * [02:24] Role of echo in cardiac arrest * [03:43] Training and cautions with echo in CPR * [06:19] Key skills for new trainees in critical care echo * [07:33] Physiological assessment in critical care echo * [09:21] Multi-organ ultrasound and venous congestion * [11:45] Systemic venous congestion in post-ICU patients * [12:18] Comprehensive cardiac output assessment * [15:50] Pitfalls and dangers of critical care POCUS * [17:18] Favorite echo views in cardiac ICU Notable Quotes * [06:33] "Critical care echo is actually complex... you need to further proceed from this basic level to intermediate and then advanced levels in which you will be able to assess physiological changes in the heart." — Dr. Hatem Soliman * [09:22] "The practice of multi-organ ultrasound and looking beyond the chest cavity for congestion is a very important advancement in point-of-care ultrasound." —Dr. Hatem Soliman * [17:24] "If I have two views to look at in a very short time... the apical five chamber view to get the LVO TVTI because that immediately gives you a clue about stroke volume and cardiac output." — Dr. Hatem Soliman Dr. Hatem Soliman Dr. Hatem Soliman is a cardiac intensivist at Harefield Hospital and senior lecturer at King’s College London. He serves on the executive board of the European Association of Cardiovascular Imaging and the editorial board of JACC: Cardiovascular Imaging.

Cardiac Tamponade in the ICU: Diagnosis, Echo, and Management with Dr. Courtney Bennett

In this episode of SoCCC Pre-Rounds, Dr. Balim Senman sits down with Dr. Courtney Bennett, a critical care cardiologist and echocardiographer at Mayo Clinic Rochester, to unpack the bedside recognition and management of cardiac tamponade. The conversation emphasizes tamponade as a clinical diagnosis, highlighting key physical exam clues such as tachycardia, hypotension, elevated JVP, pulsus paradoxus, and electrical alternans. Dr. Bennett explains the physiology of ventricular interdependence and why the rate of pericardial fluid accumulation matters more than volume alone. The episode also explores how point-of-care echocardiography supports but does not replace clinical judgment, distinguishing early findings like inflow variation from late signs such as chamber collapse. Management strategies are discussed in real-world terms, including when to urgently drain an effusion, how to stabilize patients with fluids and vasopressors while awaiting intervention, and common pitfalls like inappropriate diuresis. This episode delivers practical, high-yield guidance for clinicians managing undifferentiated shock in the cardiac ICU. Key Takeaways * Tamponade is a clinical diagnosis: Pericardial effusion alone does not equal tamponade without hemodynamic compromise * Tachycardia often comes first: Hypotension and shock may follow as compensation fails * Small, rapidly accumulating effusions can be fatal, while large chronic effusions may be well tolerated * Echo supports, not replaces clinical judgment: Chamber collapse suggests late disease; inflow variation may signal early tamponade * Drain emergently when unstable: Approach and urgency depend on patient trajectory, not imaging alone In This Episode * [00:00] Introduction * [01:11] Definition of cardiac tamponade * [01:50] Physical exam findings in tamponade * [03:25] Pulsus paradoxus: definition and mechanism * [04:57] Etiologies of pericardial effusion * [05:43] Volume vs. hemodynamic instability * [06:40] Clinical vs. echo diagnosis of tamponade * [08:09] Echocardiographic findings in tamponade * [10:02] Management: tamponade vs. stable effusion * [12:10] Stabilizing the pre-tamponade patient * [13:23] Fluid vs. diuretics in tamponade Notable Quotes * [01:28] "This is a diagnosis when a patient has pericardial effusion. So excess fluid around the heart that's causing them to have hypotension, low blood pressure, and part of that actually could be what we would describe as Beck's triad." — Dr. Courtney Bennett * [12:38] "So first and foremost, I would start with IV fluid resuscitation bolus. I don't think there's a well-defined amount that we should use. 500 a liter of fluid. You have to use your clinical assessment because many of our patients may also be peripherally volume overloaded as well. But typically in this scenario, fluid is really the upfront management."— Dr. Courtney Bennett * [13:48] "Sometimes I work with learners who think that because there's an excess of fluid around the heart, we should be giving diuretics. That's not the case because diuretics will decrease the preload and actually worsen the hypotension."— Dr. Courtney Bennett Resources and Links * Become a member of the Community: https://www.soccc.org/subscribe [https://www.soccc.org/subscribe] Dr. Courtney Bennett * https://alumniassociation.mayo.edu/colleague-notes/courtney-bennett-d-o/ [https://alumniassociation.mayo.edu/colleague-notes/courtney-bennett-d-o/] Dr. Balim Senman * https://www.linkedin.com/in/balim-senman-7561436b/ [https://www.linkedin.com/in/balim-senman-7561436b/] * https://x.com/BalimSenmanMD [https://x.com/BalimSenmanMD] * https://www.soccc.org/ [https://www.soccc.org/] Supported By: This episode is made possible by unrestricted support from Zoll LifeVest [https://cardiac.zoll.com/patients/lifevest?utm_term=life%20vest%20cardiac&utm_campaign=Cardiac+-+LifeVest+Patients&utm_source=adwords&utm_medium=ppc&hsa_acc=3725084088&hsa_cam=22620204946&hsa_grp=184004443847&hsa_ad=755140542390&hsa_src=g&hsa_tgt=kwd-2422787973254&hsa_kw=life%20vest%20cardiac&hsa_mt=b&hsa_net=adwords&hsa_ver=3&gad_source=1&gad_campaignid=22620204946&gbraid=0AAAAADqfl7Q-s3_-V8Hkd__LS91jIXf69&gclid=CjwKCAjwsZPDBhBWEiwADuO6y4FsrFZuMqyJYSsOtaDxoS4MidynidBRdOuw34-wjC3TvENsvThC4xoC188QAvD_BwE]— thanks for keeping high-impact education free for our community.

The Basics of the Pulmonary Artery Catheter with Dr. Aniket Rali

Did you know that pulmonary artery catheters are crucial for patients with unclear shock etiology? In this episode of SoCCC Pre-Rounds, Dr. Elliot Miller sits down with Dr. Aniket Rali, a dual-trained critical care and heart failure cardiologist at Vanderbilt, for a deep dive into the art and science of pulmonary artery catheterization, also known as the Swan-Ganz catheter. Dr. Rali demystifies the PAC by walking us through the fundamentals of when to use it, who should not get one, and how to interpret and troubleshoot the data it provides. Whether you're a resident inserting your first swan or a fellow refining your hemodynamic assessments, this episode will elevate your bedside practice. From contraindications and waveform recognition to zeroing, troubleshooting, and avoiding wedge-related complications, Dr. Rali shares high-impact pearls grounded in real-world CICU experience. Key Takeaways * Use PACs when shock etiology is unclear; they're diagnostic, not therapeutic * Avoid PACs in patients with endocarditis, thrombus, or proximal PE * Know your waveforms; it's your only guide during bedside placement * Always level and zero the transducer for accurate pressures * Justify PAC use daily and remove once it’s no longer needed * Troubleshoot waveform loss by checking positioning, clots, or tubing * Avoid repeated wedging; use diastolic-to-wedge trends when possible * Use chest X-ray to confirm safe placement and prevent complications In This Episode * [00:00] Introduction * [01:16] Pulmonary artery catheter basics * [02:04] Indications for PA catheter use * [06:57] Special considerations: left bundle and pacemaker leads * [08:12] Bedside placement preparation and checklist * [11:33] Presenting PA catheter data on rounds * [12:03] Ensuring data accuracy and daily safety checks * [15:17] Sequence for presenting hemodynamic data * [16:23] Cardiac output measurement methods * [18:31] Choosing between Fick and thermodilution * [20:04] Limitations in shunt physiology * [20:58] Troubleshooting PA catheter issues Notable Quotes * [02:17] "At the end of the day, a diagnostic tool is not going to treat your patient. But if it provides you with additional information that helps you reach the right diagnosis, then it becomes a valuable tool." — Dr. Aniket Rali * [09:07] "I firmly believe that the more you sweat in peace, less you bleed in war. And that holds true of any procedure." — Dr. Aniket Rali * [10:07] "You really should not be putting in a bedside swan unless you have mastered the waveforms, because the waveforms are your only guidance as to which cardiac chamber you are in." —Dr. Aniket Rali * [12:31] "I encourage trainees, next time they have a patient with a SWAN Ganz catheter in, to just have them move their arm or move the catheter up by a foot and down by a foot and see how the pressure readings change." — Dr. Aniket Rali * [27:28] "Long live the swan." — Dr. Aniket Rali Dr. Aniket Rali Dr. Aniket Rali is a heart failure and critical care cardiologist at Vanderbilt University. She’s known for her expertise in hemodynamics, real-world application of advanced monitoring, and thoughtful mentorship of trainees learning the art of bedside right heart catheterization.
