47. Case Report: Syphilitic Aortitis with Severe Aortic Regurgitation – UT Southwestern

CardioNerds (Amit & Dan) join UT Southwestern cardiology fellows (Shreya Rao, Sonia Shah, and Nick Hendren) for some delicious Dallas Tacos! They discuss a fascinating case of syphilitic aortitis with severe aortic regurgitation presenting as cardiogenic shock. Program director Dr. Gail Peterson provides the E-CPR and a message for applicants. Episode notes were developed by Johns Hopkins internal medicine resident Evelyn Song 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 57 year old male presents with 3 months of progressive dyspnea on exertion, orthopnea and lower extremity edema. However, his symptoms suddenly worsened over the past few days. He has no other known medical history or prior surgeries. Further, he denies tobacco, alcohol or illicit drug use and reports a preference for male sexual partners.  On presentation to the hospital, he had a markedly wide pulse pressure, a decrescendo diastolic murmur at the left upper sternal border and a water hammer pulse readily identifiable. TTE confirmed the clinical findings of severe aortic regurgitation with holodiastolic flow reversal in the thoracic, as well as the thoraco-abdominal aorta. Right heart catheterization was performed and showed equalization of the LVEDP and aortic diastolic pressure at 40 mmHg with Cardiac Output of 1.73 L/min. RPR was positive at a high titer (1:512). He was ultimately diagnosed with syphilitic aortitis with severe aortic regurgitation.  He progressed to cardiogenic shock and was managed with nitroprusside, dobutamine, and furosemide infusion as well as IV penicillin for syphilitic aortitis and presumed neurosyphilis. The patient was stabilized and eventually underwent an uncomplicated prosthetic aortic valve replacement and aortic root resection and reconstruction and has done well post-operatively!  Pathology was consistent with syphilitic aortitis: "lymphoplasmacytic inflammation, large foci of necrosis, and neovascularization"
