73. Case Report: Wet Beriberi & Stiff Left Atrial Syndrome – Scripps Clinic

Описание: CardioNerds (  / cardionerds  ) (Amit Goyal (  / amitgoyalmd  ) & Daniel Ambinder (  / dr_danmd  ) ) join Scripps cardiology fellows (https://www.scripps.org/cardiologyfel...) (Christine Shen (  / iconsideritjoy  ) and Andrew Cheng (https://www.scripps.org/for-health-ca...) ) for some Cardiology and California Burritos in San Diego! They discuss an informative case of Wet Beriberi and Stiff Left Atrial Syndrome. Dr. Thomas Heywood (  / jtheywood  ) provides the E-CPR and program director Dr. Malhar Patel (  / malharppatel  ) provides a message for applicants. Episode notes were developed by Johns Hopkins internal medicine resident Tommy Das (  / thomasmdas  ) with mentorship from University of Maryland cardiology fellow Karan Desai (  / karanpdesai  ) .

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 (https://www.acc.org/membership/sectio...)  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 mid-60s with history of rheumatic mitral stenosis s/p mechanical mitral valve replacement, HFpEF, and paroxysmal atrial fibrillation s/p ablation presents with subacute worsening dyspnea despite escalating diuretic doses. TTE shows an EF of 62%, normal gradients across the mitral valve without mitral regurgitation, and a dilated IVC. She is admitted with a presumed diagnosis of decompensated heart failure, and started given IV furosemide. Her symptoms slightly improve though do not resolve, and her creatinine increases from 1.4 to 2.1.  



In light of the unclear hemodynamic picture, a RHC is done, showing a RA pressure 9, RV pressure of 80/10, PAP 70/25 with mPAP 40, PCWP 30, SVR 872, CO 11 (by thermodilution), and CI 5.2. Notably, large V waves are noted on the RHC. Given concern for mitral regurgitation in the setting of large V waves, a TEE was pursued, which confirmed the lack of MR seen on TTE. Thus, her large V waves were felt to be due to stiff left atrial syndrome, and a cardiac CT showed a severely calcified “coconut left atrium”. Labwork revealed a profoundly low thiamine level (21, with LLN of 70), raising concern for wet beri beri syndrome.  



The patient’s unifying diagnosis was indolent left atrial syndrome that was exacerbated by high outout heart failure due to Wet Beri Beri syndrome. The patient received thiamine supplementation, and was diuresed to euvolemia with dramatic improvement in symptoms. A repeat RHC after thiamine replacement showed a CO of 5.7 and CI of 2.74 by thermodilution, demonstrating resolution of her high output heart failure.
