Ep. 50 Managing Pulmonary Embolism: Guidelines and Clinical Decisions with Dr. Timothy Fernandes and Dr. Robert Lookstein

BackTable Cardiology

Show Notes

Once your PERT is assembled, how do you navigate the evolving pulmonary embolism (PE) literature to improve patient outcomes at all risk levels? In this episode of the BackTable Podcast, interventional radiologist Dr. Robert Lookstein (Mount Sinai) and pulmonary critical care specialist Dr. Timothy Fernandes (UC San Diego) join host Dr. Harris Chengazi to examine the latest evidence and multidisciplinary strategies for managing acute pulmonary embolism. The discussion highlights the complexities of catheter-directed therapies in intermediate- to high-risk PE, evolving guidelines in the face of new trial data, and prioritization of improving patients’ clinical trajectories.

More about this episodeThe physicians explore the nuances of validated PE risk stratification tools, assessing the relationship between various PE scoring systems and the 2026 ACC/AHA classification for acute PE. They emphasize that the integration of clinical assessment, serial lab work, and patient history must take precedence over static imaging alone in guiding care. The doctors go on to review new trial data, including the improved RV-to-LV ratio and 90-day functional gains seen with mechanical thrombectomy in STORM-PE and reduced clinical deterioration observed with ultrasound-assisted catheter-directed thrombolysis in HI-PEITHO. The conversation concludes with a call for collaborative, safety-first management that focuses on the patient’s clinical status and long-term post-PE functional recovery.

Drug-coated balloons and a head-to-head trial against lithotripsy have put cutting and scoring balloons back at the center of complex percutaneous coronary intervention (PCI). On this episode of BackTable Cardiology, Dr. Nyal Borges interviews Dr. Ziad Ali, director of the DeMatteis Cardiovascular Institute, for an in-depth look at the mechanics, selection, and technique behind cutting and scoring balloons in complex PCI. They cover how these devices create a controlled dissection in fibrolipidic plaque, why they only fracture calcium that sits right at the lumen, and how lesion type and imaging should guide the choice between a conventional balloon, a specialty balloon and intravascular lithotripsy.

What does it actually take to open a chronically occluded pulmonary artery without pushing the patient into reperfusion pulmonary edema? On this episode of BackTable Cardiology, Dr. Hady Lichaa interviews Dr. Riyaz Bashir, interventional cardiologist and vascular medicine specialist at Mayo Clinic in Jacksonville, about the real-world, table-side technique of balloon pulmonary angioplasty for chronic thromboembolic pulmonary hypertension (CTEPH). They walk through vascular access, telescoping sheath setup, right heart catheterization, pressure wire guidance, balloon sizing, and step-by-step planning for each lobe and lesion.

When your questions in cardiology go beyond the bedside and into healthcare innovation and transformation, is an executive MBA your next step? On this episode of BackTable Cardiology, Dr. Ankit Patel interviews Dr. Abdulla A. Damluji of the Cleveland Clinic about his journey from clinical cardiology to business school, and how an MBA empowered him to drive real change in healthcare. Dr. Damluji shares how business education gave him the tools to lead new programs, challenge the financial assumptions behind emerging technologies, and build a cardiovascular center focused on aging.

When a coronary lesion won’t open at conventional pressures, what can an ultra-high pressure balloon do differently? On this episode of BackTable Cardiology, host Dr. Hady Lichaa welcomes Dr. Deepak Kapoor, interventional cardiologist at the Medical College of Georgia at Augusta University, to discuss the science, safety, and real-world applications of ultra-high pressure (UHP) balloons in calcified coronary intervention. Dr. Kapoor walks through the evolution of balloon design, the main scenarios where UHP balloons are most useful, and the technical details that set these devices apart from standard non-compliant balloons and other calcium modification tools.

As new guidelines redefine risk stratification for pulmonary embolism (PE), emerging technologies are also changing what it means to achieve procedural success. On this episode of the BackTable Podcast, interventional radiologist Dr. Julie Bulman (BIDMC) and interventional cardiologist Dr. Jay Giri (Penn Medicine) join host Dr. Chris Beck to discuss the evolving frameworks and technologies redefining standards for catheter-directed treatment of intermediate- and high-risk PE. They discuss the role of multidisciplinary PERT teams, patient selection, the impact of new thrombectomy devices, and why autologous blood return is a growing consideration for procedural success.
