53. Case Report: CTEPH & May Thurner Syndrome – Temple University
Sep 7, 2020
01:05:38
CardioNerds (Amit Goyal & Daniel Ambinder) join Temple Cardiology Fellows (Anika Vaidy and Anne- Sophie LaCharite-Roberge) in Philadelphia, PA! They discuss a fascinating case of pulmonary hypertension secondary to Chronic Thromboembolic Pulmonary Hypertension (CTEPH) associated with May Thurner syndrome and large uterine fibroids. Dr. Vaidya provides the E-CPR and message to applicants. Episode notes were developed by Johns Hopkins internal medicine resident, Eunice Dugan, with mentorship from University of Maryland cardiology fellow Karan Desai.

The CardioNerds Cardiology Case Reports series shines light on the hidden curriculum of medical storytelling. We learn together while discussing fascinating cases in this fun, engaging, and educational format. Each episode ends with an “Expert CardioNerd Perspectives & Review” (E-CPR) for a nuanced teaching from a content expert. We truly believe that hearing about a patient is the singular theme that unifies everyone at every level, from the student to the professor emeritus.
We are teaming up with the ACC FIT Section to use the #CNCR episodes to showcase CV education across the country in the era of virtual recruitment. As part of the recruitment series, each episode features fellows from a given program discussing and teaching about an interesting case as well as sharing what makes their hearts flutter about their fellowship training. The case discussion is followed by both an E-CPR segment and a message from the program director.

Patient Summary
A woman in her late 40s with history of iron deficiency anemia, uterine fibroids, and recurrent DVTs/PEs for the past 6 years despite different anticoagulation regimens, presented with syncope and progressive dyspnea on exertion. Family history was negative for DVT/PE or hypercoagulable states. On exam, she was euvolemic. Labs were significant for anemia, a normal pro-BNP, and a negative extensive hypercoagulable workup. TTE showed interventricular systolic septal flattening, right ventricular outflow tract pulse wave doppler with mid-systolic notch, and shortened acceleration time consistent with elevated pulmonary artery pressure. A VQ scan showed bilateral right greater than left mis-matched perfusion defects. CT angiogram showed right greater than left chronic mural thrombus, correlating with pulmonary angiogram which showed severe proximal and mid-vessel disease on the right and distal disease on the left. RHC corroborated the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) with mean pulmonary artery pressure of 41 and PVR of 5.2 Woods Units (WU).
To determine the etiology of her recurrent clots, a lower extremity venogram was performed and showed 80% stenosis of her left common iliac vein by the overlying right common iliac artery confirming May-Thurner syndrome. Lower extremity venogram also showed severe proximal stenosis of right iliac vein thought to be due to large uterine fibroids. Given her severe proximal and mid-vessel clot burden, she underwent pulmonary thromboendarterectomy with a subsequent drop in pulmonary vascular resistance to 1 WU. The etiology of DVTs and CTEPH was determined to be external compression related to both May-Thurner syndrome and uterine fibroids. To prevent future thromboembolic events, she underwent stenting of her left common iliac vein and hysterectomy. With these interventions, RV function returned to normal, and her symptoms completely resolved!
